Water resources management policy in the UK 1721 European legislative framework

European River Basin Districts

The Water Resources Act of 1963 can be seen as the beginning of river basin management in the UK. Now, in the early twenty-first century, water resources management falls under the over-arching framework of European legislation that takes this concept further. The European Water Framework Directive 2000 60 EC (WFD) established an integrated approach to the protection, improvement and sustainable use of rivers, lakes, estuaries, coastal waters and groundwater. It introduced two significant advances in the environmental framework for management of water resources. One of these was a move from regulation based on specific Environmental Quality Standards (EQS) and emissions control of dangerous chemical pollutants to a more The WFD introduced broad ecological objectives to promote sustainable use of water resources. This 'ecological health' is assessed by a system of classification and assessment that considers both the ecological potential of water bodies and the present and planned...

Reinforcement And Its Relation To Dependence

An effect that alters the user's perceptions, thoughts and emotions in a manner that is usually (but not always) experienced as pleasurable or rewarding. The various drugs that are potentially abused or addictive are all thought to act in different ways to stimulate a common nerve-cell pathway originating in the midbrain and running to the base of the forebrain, where it releases the transmitter chemical dopamine. This pathway is often referred to in scientific shorthand as the reward system, though this is probably a misnomer. Activation of this pathway leads to an increased probability that the behavior that caused the activation (in this case, the drug-taking) will be repeated or reinforced, and the drug is called a reinforcer. A drug must have a reinforcing effect if it is to become addictive, but it is important to recognize that reinforcement is not the same as addiction. Reinforcement is an essential mechanism for survival, learning and adaptation. The satisfaction of thirst by...

Prevention of Ingestion of Pathogens by Animals

Contaminated animal feeds are an important source of foodborne pathogens ingested by animals. This has been particularly proven by, but is not limited to, examples of Salmonella spp. in poultry and pigs. In addition, contaminated drinking water can be another source of pathogens' ingested by animals. With respect to animal feeds, two sources of microbial contamination are of particular concern the proteinaceous ingredients included during its preparation and vermin (rodents, birds) contacting them during its further handling storage. In any case, to prevent reduce ingestion of pathogens by animals on-farm, feed can be subjected to some antimicrobial treatments shown to be beneficial, e.g. in Salmonella control in pigs, including fermentation (liquid feeds), acidification by acidulants and heat treatments. Antimicrobial treatment of drinking water is another measure to reduce the risks.

Pharmacokinetic and Metabolic Data

2The terms route of exposure and route of intake refer to how a substance enters the body (e.g., by ingestion, injection, or dermal absorption). These terms should not be confused with form of intake, which refers to the medium or vehicle used (e.g., supplements, food, or drinking water).

Waterquality measurement

In countries within tropical regions, the problem of water quality is usually even more acute, since the collection and treatment of waste water is often less advanced (Gleick, 2008). In small settlements, sources of drinking water and disposal of sewage are sometimes scarcely separated, and in congested cities lacking adequate drainage, the dangers from water-borne diseases are compounded.

What Have Animal Models Taught Us

In the Lochner et al. study, female albino Wistar rats were used to study the effects of alcohol 33 , It appears that a primary aim of this study was to contrast the effects of acute and long-term alcohol exposure on the myocardium, rather than examine sex-related differences. In long-term experiments, female rats received 15 ethanol in their drinking water for 18 months. Afterwards, isolated Langendorff experiments were performed to evaluate the effects of long-term alcohol exposure as well as the effects of acute alcohol exposure in the chronically exposed alcoholic hearts. Measures of contractility included peak height of developed tension (PHT), tension time index (TTI), tension time per minute (TTM), maximum rate of rise of tension (dp dtmax),

Waterquality standards

The quality of river water and groundwater varies considerably in space and time. Typical values of physical, chemical and biological characteristics of rivers and groundwater used as a source of public water supply (PWS) in the UK are given in Table 8.1. As a consequence of the differences in the characteristics of upland rivers from lowland rivers or groundwater, these potential sources of PWS require different types and degrees of water treatment however, all three supplies need to be treated to the same drinking water standards. Rivers, particularly lowland rivers, tend to be more polluted than groundwater, and so greater efforts have been directed towards measures to improve the status of rivers. A key aspect of this attempt to restore river water quality has been the refinement and enforcement of environmental standards for river water.

Hydrological impact of an extreme precipitation event the UK Summer 2007 floods

The early summer of 2007 in the UK was, in many places, the wettest on record (Marsh, 2008) though there is some dispute as to whether it was really the wettest May to July period in England and Wales since records began in 1776 as widely reported at the time (Eden, 2009). Table 9.3 shows the 20 most extreme 3-month rainfall totals recorded since records began. There is some uncertainty about what the total average over England and Wales should be, but 2007 ranks no higher than 26th in this list. In June, two spells of heavy rainfall, on the 15th and 25th, resulted in 'pluvial' flooding of properties in Hull in Yorkshire as drainage systems were overwhelmed. Fluvial flooding occurred in Sheffield and Doncaster as the River Don overtopped its banks. Totals of over 110 mm were recorded in the Sheffield and Hull areas. July was particularly unsettled and, on the 20th, an active frontal system resulted in daily totals of over 120 mm falling on already wet ground (Fig. 9.5a). The highest...

Effects of Antioxidants on Metastasis

There are concerns that antioxidants may facilitate metastasis. That they may have this effect in some situations should not be surprising, given the above discussions. In one of the few animal studies that tested combined antioxidants, metastasis increased.192 In this study, high and very high doses of antioxidants were given in drinking water to rats with established, carcinogen-induced tumors. The high doses were about 2.4 grams of vitamin C and 1,200 I.U. of vitamin E per day (as scaled to humans). The very high doses were 10fold greater. Both groups received selenium (at 2 mg kg) and a thiol antioxidant compound (2-MPG, at 15

Maximum residue limits

Maximum levels of pesticides are also set for drinking water. Pesticides get into water from spraying, runoff, percolation or from treatment of fish in aquaculture. Good practice is increasingly being developed to minimize the levels in raw water and treatment works are developing systems to reduce incoming levels to levels acceptable for drinking water.

Broadening The Investigator Community

Drinking water, and contaminated Investigators at other federal agencies Many federal mission agencies have capabilities for addressing problems relevant to EMSP. For example, some agency investigators are involved in work at testbed sites16 on generic problems such as ground-water contamination by chlorinated solvents, petroleum hydrocarbon mixtures, and certain heavy metals. Research that utilizes these testbeds can provide new knowledge that can be applied directly to cleanup of the weapons complex.

If You Have Swallowing Problems

About half of all persons affected by MS experience dysphagia or difficulty in swallowing. Dysphagia can be a serious problem. It can result in choking, aspiration, malnutrition, dehydration or pneumonia. Coughing when drinking water, choking when eating, and or, having a hoarse, wet sounding voice are indications that you may have a swallowing problem. If you suspect a swallowing problem, you may benefit from a consultation with a speech-language pathologist. Once a specific problem has been identified, the speech-language pathologist can recommend foods, beverages, textures, and techniques to improve the quality, enjoyment, and safety of your eating.

Glutathione as an Anticancer Compound

Effect on cancer progression or could assist or inhibit it. Each of these results has been observed in animal studies. For example, in one study in rats, 5.3 grams per day, as scaled to humans, given orally caused partial or complete regression in 81 percent of established afla-toxin-induced liver tumors.41 In another rat study, oral administration of 2 g kg of glutathione inhibited growth of transplanted breast cancer cells tumor inhibition was associated with a decrease in PGE2 production, suggesting that intracellular concentrations of glutathione were increased.42 At least one animal study reported detrimental effects 500 mg kg of glutathione in the drinking water increased the size of chemically induced tumors in rats.43 In other animal studies, glutathione had no effect on tumor growth.44

Background And Relevant Pharmacokinetics

Iodine is an essential trace element required for the proper functioning of the thyroid gland. It is mainly consumed as iodide salts obtained from sea salt, shellfish and seawater fish and vegetables, which are more bioavailable than the organic form of iodine. The iodine content of soil is considered to be one of the most variable of all mineral levels, influenced by local geography and the type and quantity of fertiliser used in agriculture (Gropper et al 2005). The amount of iodine present in local drinking water (0.1-100 ig L) is reported to be a good indication of soil levels (Geissler & Powers 2005). In iodine-deficient areas, the iodide concentration in drinking water is

Type II Estrogen Receptors

In addition to inhibiting cell proliferation by binding to type II receptors, flavones have prevented the overexpression of MeHPLA esterase by cancer cells this enzyme degrades MeHPLA, thereby decreasing its growth-inhibitory effects. Oral administration of luteolin (at 56 mg kg) in drinking water for seven days blocked estrogen stimulation of MeHPLA esterase in rat uterine tis-sues.61 The equivalent human dose is roughly 910 milligrams of luteolin per day. Similar results were seen after subcutaneous administration of luteolin in rats (at 5 mg kg).69 The equivalent human oral dose is about 540 milligrams per day.

Invivo Activity of EGCG

Both EGCG alone and green tea extract appear to have cancer preventive effects in vivo, largely due to inhibition of free radical damage and improved carcinogen metabolism. Dozens of studies have reported that topical, oral, or intravenous administration of EGCG or GTE inhibited development of rodent neoplasms in a variety of tissues (tongue, lung, stomach, skin, for example) by a variety of chemical inducers and promot-ers.128-14a 160 In the mouse studies, the typical dose was a 1 to 2 percent tea (from tea leaf) as the sole source of drinking water.141-145 This provided the equivalent of about 330 to 660 mg kg of GTE. The equivalent human Oral administration of approximately 100 mg kg of EGCG in drinking water inhibited metastasis of transplanted melanoma cells in mice by about 72 percent.121 Although not a study on tumors, 1.3 percent green tea as drinking water (about 140 mg kg EGCG) inhibited VEGF-induced corneal angiogenesis in

Hazard Identification

Studies on the effects of orally administered arginine on the immune system have provided conflicting results. Barbul and coworkers (1980) reported significant increases in thymus weights, thymic lymphocyte content, and in vitro activity of thymic lymphocytes after supplementing the diet of male mice with 0.5, 1, 2, and 3 percent arginine hydrochloride (one-half in the diet and one-half in drinking water) for 6 days. No dose- response was found, with the maximum stimulation noted at 0.5 percent supplementation of the normal chow diet containing 1.8 percent arginine. Reynolds and coworkers (1990) reported significantly increased thymus weight, spleen cell mitogenesis, and inducible natural killer cell activity in mice after oral arginine (drinking water) doses of 60, 120, or 240 mg kg of body weight d. No dose-response was reported with maximum stimulation noted at 60 mg kg of body weight d. In young or aged rats, ingestion of diets supplemented with 3 percent L-arginine for 15 days...

Adverse Reactions

A 13-week subchronic oral toxicity study of perilla leaf extracts in drinking water did not show any acute toxicity. There were no treatment-related changes in body weight gain or in haematological or blood biochemistry values. Nor were there any treatment-related histopathological changes observed in the highest dose group (Yun etal 1999).

Presentday Cultivation And Usage

The plant is cultivated in various regions of world, including Afghanistan, Bangladesh, Ethiopia, Gambia, Ghana, India, Indonesia, Iran, Malaysia, Myanmar, Nepal, Oman, Pakistan, the Philippines, Qatar , Saudi Arabia, Sudan, Tanzania, Thailand, Togo, Uganda, the United Arab Emirates, and Vietnam. The plant readily colonizes on stream banks and in savannah areas, where the soils are well drained and the water table remains fairly high all the year round. Fairly drought-tolerant, it yields much less foliage where continuously under water stress. It is not harmed by frost, but can be killed back to ground level by a freeze. It quickly sends out new growth from the trunk when cut, or from the ground when frozen. The young leaves, flowers, and pods are common vegetables in the Asian diet, considered to be of high nutritional value. Seeds are used for water purification. Coagulant protein and various phytochemicals identified for medicinal use have been isolated and investigated (Table...

Transport of pollutants in groundwater

There is a very important issue about the use of groundwater as a source of water supply. Potentially, because of the filtering effect of the soil and unsaturated zone, the geochemical quality of groundwater is normally expected to be better than most surface water sources. However, if a groundwater body becomes polluted, then it can become unusable for drinking water. Many countries have very strict regulations about land uses in important groundwater recharge areas. Sweden, for example, has road signs indicating when a recharge area is being entered, while in the UK maps of source protection zones can be found on the Environment Agency web site.6 In the UK, three protection zones are defined with respect to time of travel in the saturated zone to an abstraction well In the past, however, there has been much careless and thoughtless pollution of groundwater. On Long Island, New York, for example, over 50 per cent of the water supply wells have had to be closed, primarily because of...

Ethics of Human Brain Research

The use of mind-altering drugs has long been and remains controversial. A striking example was the public's response in August 2004 when trace amounts of fluoxetine hydrochloride (Prozac), a selective serotonin reuptake inhibitor were found in drinking water in the United Kingdom. It is not known how it got there. The emotional reaction was even greater than the response of many persons to the first use of widespread fluo-ridation of drinking water to prevent caries.

Parasites that invade and remain in the enterocytes of the intestine

Cryptosporidium parvum is an obligate intracellular protozoan parasite in the phylum Apicomplexa. The strains of C. parvum are classified into two major genotypes as either type I or type II. Type I strains usually only infect humans while type II strains infect both animals and humans (Leav et al., 2003). Infection occurs after ingestion of food or water contaminated with environmentally resistant oocysts shed from fecal matter. The most infamous outbreak of cryptosporidiosis occurred in Milwaukee, WI, in 1993 where over 400 000 people were infected from a contaminated water source (MacKenzie et al., 1995). The infectious dose of the type I strain involved in the outbreak was estimated as 1-10 oocysts (Dillingham et al., 2002). When oocysts are ingested, they are resistant to the acidic environment in the stomach and pass into the intestine. In the presence of bile salts and pancreatic enzymes, the sporozoites excyst and invade the epithelium surface of the intestine in both the...

Implications for foodborne disease treatment and prevention

Also, basic sanitation, including proper disposal of animal and human waste as well as safe drinking water, is not available. As illustrated in this chapter, most parasitic infections are due to fecal-oral contamination. Therefore, even with free drug distribution programs promoted by multiple organizations such as the WHO to treat some of the most common infections (e.g. A. lumbricoides with albendazole and mebendazole), pharmacologic approaches will be only short-term solutions to a larger more challenging problem (Bennett and Guyatt, 2000 Montressor et al., 2002). Furthermore, there is concern that blanket treatment of an entire population with drugs regardless of the infection status of an individual will promote drug resistance. Drug-resistant helminths have already been found in the livestock industry, and there are scattered reports among human populations (Albonico et al., 2004 Jones and George, 2005).

The future data requirements of hydrology 2041 Coping with data limitations

Where uncertainty might be important, then it might also be the case that some resources can be made available to collect additional data to try to constrain the uncertainty in informing any decision to be made. This then presupposes some understanding how different types of data might have value in constraining uncertainties in this way. However, searching the hydrological literature suggests that little or no such guidance is available (there is some related work on rain-gauge network design to reduce uncertainty in areal estimates of rainfall inputs and the siting of additional ground water wells to improve the calibration of groundwater models). This will be an important topic for hydrological research in the future.

Veterinary Drugs and Growth Promoters Residues in Meat and Processed Meats

Visual Difference

Veterinary drugs, which comprise a large number of different types of substances, are generally intended for therapeutic (to control infectious diseases) and prophylactic (to prevent against infections) purposes in farm animals. Other substances with growth promoting effect may exert antimicrobial effect against the microbial flora in the gut to take maximum profit of nutrients in the feed or by affecting the animal's metabolism. Most of these substances are orally active and can be administered either in the feed or in the drinking water. Other active hormones are applied in the form of small implants into the subcutaneous tissue of the ears. These are slow release (several weeks or months) devices and the ears are discarded at the slaughter. Growth promoters allow a better efficiency in the feed conversion rate. The net effect is an increased protein deposition, partly due to muscle proteases inhibition (Fiems, Buts, Boucque, Demeyer, & Cottyn, 1990), usually linked to fat...

Antibacterial activity

Naidu and co-workers (1990 1991) have identified specific LF-binding proteins in Staphylococcus aureus isolated from human and animal infections as well as among various species of coagulase-negative staphylococci causing bovine mastitis. Apo-bLF at concentrations of 0.1 -0.4 could convert compact colonies of Staphylococcus haemolyticus transient to diffused in soft agar (Godo et al., 1997). This surface-active property of LF has prevented autoaggregation of cocci in compact ball-like colonies by hydrophobic interaction or trypsin-sensitive proteins. In vivo anti-staphylococcal activity of hLF, bLF and bLF hydrolysate was reported in an experimental mouse model (Bhimani et al., 1999). All the LF preparations demonstrated weak in vitro antibacterial activity while holo-LFs showed no activity. LF-treated mice (1 mg, i.v.) when injected with 106 staphylococci, showed 30-50 reduction in kidney infections, and viable bacterial counts in the kidney decreased 5- to 12-fold. The inhibitory...

Using surveillance data to characterize and analyze risk factors for foodborne illness

The main limitations of the FoodNet surveillance have been discussed (CDC, 2001a). Currently the system encompasses nearly one-fifth of the US population, although the data may not be entirely representative of the national situation. Secondly, FoodNet does not completely eliminate underreporting. Since most foodborne illnesses will not require in-depth medical investigation, data still merely reflect the fraction of cases that are laboratory-confirmed. Even if an illness case becomes the object of a laboratory work-up, procedural and performance differences among laboratories may influence the isolation outcome. For instance, while stool specimens are routinely tested for Salmonella and Shigella and often for Campylobacter, testing for E. coli 0157 is only carried out half the time, and other pathogens even less frequently. Importantly, some reported cases may be the result of an exposure not linked to food, such as drinking water or person-to-person contact, and the source of...

Dengue hemorrhagic fever shock syndrome

Acute diarrhea affects almost everyone at some time, usually from eating contaminated food or drinking contaminated water. Diarrhea is not a disease in itself, but a symptom. While it may not seem to be a serious problem, if it remains untreated severe diarrhea can lead to dehydration and electrolyte imbalance. This is a particular concern among the very young and the very old. Treatment During a severe attack, water and electrolytes must be replaced to prevent dehydration. Drinking water with sugar and salt added is one way to do this (one teaspoon salt and four teaspoons sugar dissolved in one quart of water). antidiarrheal drugs should not be taken to treat diarrhea caused by infection, since they may in fact prolong the illness. See also cholera, cryptosporidiosis, enterovirus, ESCHERICHIA COLI, ESCHERICHIA COLI 0157 h7, giardiasis, marburg virus.

Bioinorganic Chemistry And Its Pharmaceutical Applications

Centuries, while the remainder enter the human body simply because they are present naturally in drinking water or in the plant and animal tissues which make up our food. The concentrations of the adventitious elements vary from person to person, depending on their geographical environment and their eating habits.

Candida lusitaniae infection

Chicken or when the organisms are transferred from the raw meat or raw meat drippings to the mouth. The bacteria are common among healthy chickens on chicken farms, where they may spread undetected among the flocks (perhaps through drinking water supplies). When the birds are slaughtered, the bacteria are transferred from the intestines to the meat. Prevention Hands should be washed after using the toilet. Anyone with diarrhea should use a separate towel and washcloth and should not prepare food (especially uncooked food). Properly cooking chicken, pasteurizing milk, and chlorinating drinking water will kill the bacteria.

Set realistic deadlines

Your body is 70 water, so it's easy to lose weight quickly. Any diet that dehydrates you will create quick, dramatic weight loss. If you want to lose ten pounds over the weekend, just stop drinking water Of course that would be pretty dumb and pretty dangerous too, but that's precisely what you're doing when you lose weight rapidly - you're simply dehydrating yourself (or even worse - you're losing muscle too ) Your goal should be to lose body fat, not body weight.

Legionella Pneumophila Cruises Burning Mouth Syndrome

Outbreaks have occurred after persons have inhaled spray from a contaminated water source (such as air-conditioning cooling towers, whirlpool spas, or showers) in workplaces, hospitals, or other public places. Infection isn't spread from one person to another, and there is no evidence of people becoming infected from auto air conditioners or household window air conditioners. Legionella can be found in many different water systems, but the bacteria reproduce best in warm, stagnant water such as is found in some plumbing systems and hot water tanks, cooling towers and condensers of large air-conditioning systems, and whirlpool spas. Religious customs also affected many treatments for leprosy. In 250 B.C., Chinese patients pricked their swollen limbs to let out the foul air. Ramses II of Egypt believed that people with leprosy who used his water wells would be cured. And in medieval Europe, it was believed that leprosy could be cured by the touch of a king.

Pressure potential pressure head and hydraulic head

When the hydrostatic pressure of water within the subsurface is greater than the atmospheric pressure, the pressure potential is positive. Where it is less than atmospheric pressure, the subsurface water system has a negative pressure potential, which is also termed the matric potential, capillary potential, suction or tension. Within soil, regolith or rock that is fully saturated, the pressure potential can be measured with a piezometer. A piezometer is a narrow tube installed within the ground, where only the lower section is in contact with subsurface water system via a screened section and gravel pack (Fig. 6.5).

Requirements and High Intakes

Lithium deficiency reportedly results in depressed fertility, birthweight, and life span, and altered activity of liver and blood enzymes in goats. In rats, lithium deficiency apparently depresses fertility, birthweight, litter size, and weaning weight. Other in vitro biochemical actions suggesting that lithium could possibly act as an essential element include the stimulation of growth of some cultured cells, and having insulinomimetic action. Lithium is best known for its pharmacological properties it is used to treat manic-depressive psychosis. Its ability to affect mental function perhaps explains the report that incidence of violent crimes is lower in areas with high-lithium drinking water.

Dental programs in Mexico

In Mexico, a school-based caries preventive program was established in the 1970's in the State of Mexico it was a pioneer program, and later in 1988 the program of salt fluoridation was implemented for the first time as a pilot program in the state. The program was carried out with technical support from the Pan American Health Organization (PAHO) and financial from W.K. Kellogg. Then, the salt fluoridation program is positioned as a nationwide policy in 1992. Because in the country there are five states and other municipalities with concentrations of fluoride in drinking water above the optimum amount, steps were taken to prevent consumption in these regions.

Flattened head syndrome See positional plagio

Fluoride's benefits for teeth were discovered in the 1930s when dental scientists noted remarkably low decay rates among people whose water supplies contained significant amounts of natural fluoride. Several studies conducted during the 1940s and 1950s confirmed that when a small amount of fluoride is added to the community water supply, decay rates among residents of that community decrease. Two of the most common sources of fluoride are via tap water and fluoridated toothpaste. Although fluoride occurs naturally in all water sources, in most major municipalities it has been added to the water to help prevent tooth decay for the past 50 years. The recommended fluoride level in community water systems is 0.7 to 1.2 parts fluoride per million parts water. while fluoride is important, it only works when used at the appropriate levels. Too much fluoride can cause a harmless discoloration of the teeth known as enamel fluorosis, which is usually caused when children take fluoride...

Dietary Contamination

Nickel and bismuth are not considered to be common dietary contaminants. Nickel is mainly inhaled as a dust by workers, whereas bismuth is mainly ingested in bismuth-containing medications such as Pepto-Bismol. Vegetables contain more nickel than other foods, and high levels of nickel can be found in legumes, spinach, lettuce, and nuts. Baking powder and cocoa powder may also contain excess nickel, possibly by leaching during the manufacturing process. Soft drinking water and acid-containing beverages can dissolve nickel from pipes and containers. Daily nickel ingestion can be as high as 1 mg (0.017mmol) but averages between 200 and 300 mg (3.4 and 5.1 mmol).

Sources of Salt Intake

Various approaches to measuring the daily salt intake in individuals have been tried. Salt comes from (1) natural products (2) salt added during industrial processing (3) salt from catering (4) other sodium-containing sources (5) discretionary use of salt in cooking and table salt and (6) sodium in drinking water. Traditional methods of estimating salt intake, e.g., with economic data, lead to marked errors and usually substantial overestimates. These have now been replaced by more modern methods.

Parasites that are in the intestine and cross the intestinal barrier

The definitive hosts for the parasite are in the family Felidae, which includes the domestic cat. A cat becomes infected after consuming raw meat containing encysted parasites (e.g. a mouse). The parasites are released in the cat's intestine and undergo sexual replication to form environmentally resistant oocysts. These oocysts can contaminate fresh produce and municipal water systems as evidenced by the outbreak in British Columbia in 1995 where an estimated 2800-7000 people were infected (Bowie et al., 1997). Once ingested by intermediate hosts, the parasite undergoes rapid asexual replication as a tachyzoite form until it converts into the slowly growing encysted bradyzoite in muscle and brain tissues. Once ingested from undercooked meat, these encysted bradyzoites are resistant to acid pepsin digestion and can continue the parasite's life cycle in either the definitive or intermediate hosts. The intermediate host cycle (virtually all warmblooded animals) from carnivorism can exist...

California encephalitis See encephalitis California

In the 1980s, more than 3,000 residents in Ben-nington, Vermont, became ill with diarrhea when their town's water supply was contaminated with the rod-shaped bacterium C. jejuni. The most common source of Campylobacter infection is in contaminated poultry (one-third to half of all raw chicken on the market is contaminated). Consumers get sick when they eat under-cooked chicken, or when the organisms are transferred to the mouth from the raw meat or raw meat drippings. The bacteria is common among healthy chickens on chicken farms, where it may spread undetected among the flocks (perhaps through drinking water supplies). When the birds are slaughtered, the bacteria is transferred from the intestines to the meat.

Physiotherapy procedures in the management of the patient with prostate cancer

Host Derived Bacterial Signaling Compounds HDBSCs How Microbial Pathogens Sense Host Stress at the Intestinal

The discovery by Lyte that host epinephrine and other catecholamines provide major signals to E. coli and other pathogens to express a more adherent and hence virulent phenotype against the intestinal mucosal epithelium set the stage for the discovery of similar compounds released during host stress that might signal pathogenic organisms to express enhanced virulence (Chen et al. 2003). We began to work with P. aeruginosa in a unique animal model that we developed in our laboratory. To recreate operative trauma and the colonization of P. aeruginosa in the distal intestinal, we performed a 30 surgical hepatectomy in mice and simultaneously injected P. aeruginosa strain 27853 into the cecum. To mimic the clinical circumstances of a major surgical intervention, mice were fasted for 48 h where they drank only D5W in their drinking water. This model recapitulated a typical major surgical intervention by imposing surgical injury, intestinal colonization with a hospital pathogen, and a short...

Bioavailability of Ingested Aluminum

Complete balance studies using the 26Al tracer have been undertaken to determine bioavailability. These showed that the fractional uptake of aluminum following administration as a citrate solution was 0.005 and following its intake as hydroxide was 0.0001. The coadministration of citrate with aluminum hydroxide enhanced aluminum uptake by a factor of approximately 10. A later study measured the bioavailability of aluminum in drinking water, and a fractional uptake of 0.002 was determined. It follows that at a maximum concentration of aluminum in drinking water of 200 mg 1, this source will normally account for approximately 6 of total (non-medical) aluminum uptake.

Fightor Flight Response

In August 2004, fluoxetine hydrochloride (Prozac), a selective serotonin reuptake inhibitor (SSRI), was found in drinking water in the United Kingdom. How it got there, no one knows. Is it possible that mind-altering drugs might someday be added to drinking water the same way that fluoride is added to prevent caries

Water contaminated 297

Water, contaminated Water can be a source of infection if it contains infective or parasitic organisms and is drunk, swum in, or comes into contact with food. Throughout the world, tainted water is a major source of the spread of infectious disease, including viral HEPATITIS A, DIARRHEA, TYPHOID FEVER, CHOLERA, AMEBIASIS, and some types of worm infestation. Water can become contaminated by feces (either human or animal) that contain infective material in rivers, lakes, reservoirs, or wells. Contamination can also occur via untreated sewage or leakage between sewage and water supplies. The risk of waterborne infection in the United States is far less than in the Third World because of adequate sanitary facilities, sewage treatment and disposal, and the sterilization and testing of municipal water supplies. This does not mean that all U.S. drinking water is safe, however. The CRYP-TOSPORIDIOSIS parasite is believed to infect millions of Americans each year through tainted tap water. In...

Division of Bacterial and Mycotic Diseases A

Cause Humans are infected by swallowing contaminated drinking water from shallow wells and ponds found commonly in the tropics. Worm larvae penetrate the intestinal wall, develop and mature in the abdominal cavity, and finally migrate to areas just underneath the skin. The adult worm discharges embryos through an opening in the skin. The entire process (from drinking water to embryo) takes about 13 months. Prevention It is important for travelers to purify drinking water, boiling any water that appears impure. Uncooked food washed with contaminated water should be avoided.

Evidence for a Role in Alzheimers Disease

The etiology of nonfamilial, sporadic AD is unknown. However, cases have been attributed to head injury and environmental factors, including aluminum. Involvement of aluminum in AD has been suggested because (1) of the similar symp-tomologies of AD and dialysis dementia (2) the administration of aluminum to animals produces histological changes within the brain that are, in some respects, similar to those seen in the brains of AD patients (3) of some reports indicating the presence of aluminum within the cores of senile plaques (4) of the results of some epidemiological studies that have linked AD incidence either with aluminum levels in drinking water or with its consumption as medicines and (5) a disease similar to AD is prevalent in some Pacific islands (Guam), where the levels of aluminum in soils and water are high.

Scaling disorders of infancy 441

To lower the risk of an accident, families should lower the temperature setting of the water heater and install scald-prevention devices (such as faucet covers) for the water systems in the home. Water heaters usually come from U.S. factories set at 140 F or above a temperature that can scald a child within two seconds. The simplest method of protecting against scalds throughout the house is to reduce the temperature setting to between 120 and 125 F. If that is not possible, installing scald-protection devices can help.

Chlamydial pneumonia See pneumonia

For centuries cholera thrived only in northeast India, where outbreaks still occur regularly, but as the world trade routes opened in the 1800s, cholera became pandemic, spreading throughout the world and killing millions of people in a series of epidemics. It was London physician John Snow who correctly identified sewage-contaminated drinking water as the source of the epidemic of 1853-54. In his research, he compared the incidence of cholera in a neighborhood with two different sources of water, one of which was contaminated with sewage. cholera-infected bilgewater into the Lima harbor. The bacteria contaminated the fish and shellfish, which peruvians ate raw from there the bacteria got into the sewers and from there into the water supply. The disease then spread throughout South and Central America where the epidemic continues to this day. The particular bacterium responsible for the pandemic El tor (V. cholerae 01) can survive in water for long periods. By September 1994 more than...

Pa Supplementationendogenous Versus Exogenous

Because wheat bran is one of the richest dietary sources of PA, some studies 17,44,45 , have used it in dietary models of PA intake. However, the use of wheat bran as a source of PA compared to addition of pure PA to a purified animal diet or drinking water brings out the issue of endogenous versus exogenous sources of PA. Due to its chemical properties, pure exogenous PA in the diet can interact with other food components. For example, it may form complexes with the mineral, protein or starch components in the diet 12 . Pure PA given in the drinking water may also interact with other food components provided that it is consumed concurrently with diet. If the animal consumes its water and food at different time periods, then the interaction of the pure PA in the drinking water with other components of the diet may be minimized. However, endogenous PA present within the matrix of a high-fiber food source such as wheat bran, may not be able to interact with other dietary components or...

Carcinogenicity Tests Animal Bioassays

The basic approach for carcinogenicity testing involves administering the test material to two suitable animal species for a considerable proportion of their natural lifespan. Because of their small size and relatively short life expectancy, the rat and mouse are the species of choice, although the hamster is occasionally used. In the US, inbred strains of animals are widely used (the F344 rat and the B6C3F1 hybrid mouse), although out-bred strains are commonly used in Europe. To examine the carcinogenic potential of food components, the test substance is usually given in the diet, although in some circumstances administration may be in the drinking water or by gavage. The study continues until a certain proportion in one or other of the treatment groups has died or has been killed in a moribund state. As a minimum, 50 animals are allocated at random to each of the experimental groups, allowing a statistically significant carcinogenic effect to be detected if five animals in a test...


High levels of copper may aggravate PMS and it can be increased by the use of birth control pills. Excess copper can cause mental and emotional problems and may be prominent in schizophrenia. Anemia not helped by iron may be an indication of elevated copper levels. Serum copper, elevated by estrogens, rises progressively during pregnancy and takes several months to return to normal after delivery, during which time the mineral could be a factor in the depression and psychosis women often experience right after giving birth. Excess copper may be getting into the diet from contaminated food and water and copper pipes through which drinking water flows.


Acrylamide is considered by the International Agency for Research on Cancer to be ''probably carcinogenic to humans'' based on the results of several animal carcinogenicity studies. As a result, there has been widespread concern about the potential risks from exposure to acrylamide among industrial, manufacturing, and laboratory workers. Consumer exposure to acrylamide in treated drinking water has posed a much lower concern since drinking water is subject to special treatment techniques that control the amount of acrylamide in drinking water.


We recently completed a study in which we tested the hypothesis that chronic moderate alcohol consumption reduces cardiac ischemia-reperfusion injury by activation of mitoKATP channels 45 , Adult male Sprague-Dawley rats received a diet of rodent chow and 18 ethanol (vol vol) in their drinking water for 10 months, a feeding schedule previously reported to induce cardiac protection 27 , At the end of the treatment period, there were no differences in body weight, heart weight, baseline LV developed pressure, or coronary flow between ethanol-fed rats and age-matched controls. Serum ethanol levels were measured prior to each experiment and averaged 15 1 mg dL (3 mM) 45 , Hearts from control and treated rats were isolated and perfused using a modified Langendorff method. After a 20 minute equilibration period, hearts were subjected to 45 minutes of no-flow ischemia and 48 minutes of reperfusion. LV developed pressure recovered to 45 of pre-ischemic levels in hearts from ethanol-fed...

Health Risks

Disasters often pose significant health threats. One of the most serious concerns after a disaster, especially a natural disaster, is sanitation. Disruptions in water supplies and sewage systems can pose serious health risks to victims because they decrease the amount and quality of available drinking water and create difficulties in waste disposal. Drinking water can be contaminated by breaks in sewage lines or the presence of animal cadavers in water sources. These factors can facilitate the spread of disease after a disaster. Providing potable drinking water to victims and adopting alternative methods of sanitation must be a priority after a disaster. Disasters can also cause disruptions to the health care infrastructure. Hospitals and health centers may suffer structural damage, or health personnel may be among the casualties, limiting the ability to provide health services to disaster victims. Emergency Health Kits that contain essential medical supplies and drugs are often...


Recently, there has been increased interest and development in calcium phosphate-based remineralization technology (Reynolds and del Rio, 1984 Rosen et al., 1984). One of the newest modalities in preventive dentistry is the introduction of amorphous calcium phosphate (ACP) into methacrylate composites, gum, pastes, and other dental products. Casein is the predominant phosphoprotein in bovine milk and accounts for almost 80 percent of its total protein, primarily as calcium phosphate stabilized micellular complexes (Aimutis, 2004). Several laboratory and animal experiments have investigated the low cariogenic potential and the possible cario-static activity of dairy products (milk, casein, caseinates and cheeses). The use of casein as an anticariogenic additive to food, toothpaste or drinking water has not been implemented because of its adverse organoleptic properties and the large amount required for efficacy (Reynolds, 1998).

Riparian rights

The common law rights of a riparian owner come from the ownership of property adjoining a natural watercourse (or a lake). Riparian rights are normally subject to reasonable use of the watercourse by all who have access to it. A riparian owner has the right to use the water (from a watercourse or lake) for domestic purposes, drinking water for cattle and for irrigation purposes (provided that any diversion for irrigation is not continuous and it is returned without diminution, other than by evaporation and absorption).

Poliomyelitis 405

When improved sanitation and other health measures arrived (such as water purification and milk pasteurization), there was less chance for babies and young children to contract the mild form of the disease and become immune. When the disease struck older children and adults, it was more likely to paralyze. In northern Europe and the United States, small epidemics began to appear in the late 19th and early 20th centuries. It was not until the summer of 1917, when 27,000 U.S. citizens were paralyzed and 6,000 more died, that the real threat began to emerge. The northeast was especially hard hit in New York City and its suburbs, more than 9,000 cases were reported and 2,488 people died. The 1917 epidemic set off a panic as thousand fled the city to mountain resorts. Movie theaters were closed, meetings were canceled, and public gatherings were shunned. No one understood what spread the disease, so doctors stopped performing tonsil-lectomies until fall and warned children not to drink...


Fluoride as a caries-preventive agent was discovered as the side effect of fluorosis in teeth in areas with elevated levels of fluoride in the drinking water (Ten Cate, 2004). Research on the oral health effects of fluoride started around 100 years ago. For the first 50 years or so it focused on the link between water borne fluoride - both natural and artificial - and dental caries and fluorosis (Petersen, et al., 2004). It was difficult to determine small (sub-ppm) concentrations of fluoride in drinking water. Nevertheless, the early studies on fluoridation of the drinking water were convincing and initiatives were taken to add various types of fluorides to other oral hygiene products (Ten Cate, 2004). In the second half of the 20thcentury, fluoride research was focused on the development and evaluation of fluoride toothpastes and rinses and, to a lesser extent, alternatives to water fluoridation such as salt and milk fluoridation. Drinking water is not fluoridated in Sweden, and...

Graham Sylvester

He advocated bread at least twelve hours old, made of the whole of the wheat, and coarsely ground. He also recommended hard mattresses, open bedroom windows, cold shower baths, loose and light clothing, daily exercise, vegetables and fruits, rough (whole-grain) cereals, pure drinking water, and cheerfulness at meals. He taught that temperance included both physical and moral reform.


As will be discussed in more detail below, PA has been shown to be protective of a variety of cancers in many different in vitro and in vivo models. However, comparison of these studies is complicated by differences in the method of PA supplementation. A majority of the studies on PA and cancer have used either 1-2 pure PA supplemented to a low-fiber diet or added to the drinking water, while a limited number of studies used cereal brans as a source of naturally occurring PA. Which method of PA supplementation is more effective is not clear. Because animals eat various amounts of diet and drink varying volumes of water, those fed, for example, 1 PA in the diet, may be receiving different amounts of PA than animals consuming drinking water supplemented with the same percentage of PA, particularly because the addition of PA to the drinking water may also require adjusting the pH of the water to make it more palatable for the animals 18 . This issue is further complicated by the fact...

Colon Cancer

IN VIVO STUDIES-PURE PA IN DRINKING WATER In in vivo studies, pure PA given in the drinking water has been shown to reduce the rate of colonic cell proliferation, an early biomarker of colon cancer risk, at early (four weeks) 22 and late (36-40 weeks) 23,24 time points (Table 14.1). It has also been shown to reduce various colon tumor parameters when given at either the initiation 14,25 or promotional stages 24,26 of colon carcinogenesis (Table 14.1). When administered to azoxymethane (AOM)-treated rats, up to five months post-initiation, PA (2 ) significantly reduced colon tumor number, size and mitotic rate, when compared to the control group 24 , suggesting that PA can have anticancer effects at both the initiation and promotion stages of colon cancer. Also, using 2 PA provided in the drinking water, Pretlow et al. 26 showed a reduced number of colon tumors and tumor volume (Table 14.1).

Mammary Cancer

Table 14.2 provides a summary of animal studies on the effect of endogenous or exogenous PA on mammary cancer and its early risk markers. In animal studies, dietary PA supplementation (1.2 ) reduced cell proliferation in the mammary gland 15 . The reductions were stronger when the PA was added to diets supplemented with high levels of iron and calcium, suggesting that PA was binding these cations and inhibiting their promotive effects. In mammary tumorigenesis studies, PA supplementation was initially shown to bring about a slight, nonsignificant decrease 53 . However, subsequent experiments 16,54 showed that pure PA, supplemented in the drinking water, effectively decreased tumor incidence in a dimethylbenzanthracene (DMBA) mammary tumor model. Since then, similar effects have been observed with pure PA provided in the diet 32,55 . The debate over endogenous versus exogenous PA discussed above for models of colon cancer has been addressed to an extent for models of mammary cancer by...


Nisatidine See histamine receptor antagonists. nisin antibiotic isolated from lactic Streptococcus group N inhibits some but not all Clostridia not used clinically. The only antibiotic permitted in the UK to preserve specified foods. It is naturally present in cheese, being produced by a number of strains of cheese starter organisms. Useful to prolong storage life of cheese, milk, cream, soups, canned fruits and vegetables, canned fish and milk puddings. It also lowers the resistance of many thermophilic bacteria (see thermophiles) to heat and so permits a reduction in the time and or temperature of heating when processing canned vegetables. nitrates The inorganic form of nitrogen used by plants found in soils and included in inorganic fertiliser. Nitrate is a natural constituent of crops in amounts sometimes depending on the content in the soil. Also found in drinking water as a result of excessive use of fertilisers.

Not long ago, Britain's Drinking Water Inspectorate announced that they'd found Prozac in the country's drinking water. Needless to say, the citizenry took it very calmly. Apparently the drug is ending up in their drinking glasses by way of the water supply. Yum There's nothing quite as tasty as Prozac Already Been Calming. Some people may have slowly releasing drugs implanted under their skins to correct specific molecular abnormalities in their brain (The Mad Dog Weekly, 2004). 2004, Britain's Environment Agency revealed that Prozac has been found in groundwater and rivers that provide Britain's drinking water.

Major sources are fluoridated water and dietary supplements, toothpaste, seafood, tea. Most toothpastes contain 1 mg g. but prescription strength products may contain as much as 5 mg'g. The water in some world regions naturally has a fluoride content well in excess of 1 mg l (Singh et al 2001). Bottled Vichy water contains 5mg t, most other bottled waters contain much less. Water purification systems, with the exception of reverse osmosis and deioni ution systems, remove little fluoride from water (Whitford. 2000). Min Res 1998 13 1660-7 Malhotra A. Tewari A. Chawla MS.

Eating too fast or too much puts pressure on the sphincter muscle, weakening it, as does too much body weight. Eating the wrong foods or food combinations can cause heartburn. Foods that can act as muscle relaxants causing the sphincter muscle to open inappropriately are chocolate, fatty foods, and alcohol. Foods that increase the acidity of the stomach are coffee, beer, milk, and colas. Coffee, citrus foods, hot spicy foods, and tomatoes can irritate an already sensitive esophagus. Anxiety and stress can interfere with digestion. It is best to eat 3 hours before lying down. Lying on the left side eases symptoms because the esophagus enters the stomach on the right. Drinking water at the first sign of pain can dilute irritating acids.


Perchlorate exists as an anion (CIO4 ) with a central chlorine atom surrounded by four oxygen atoms arranged in a tetrahedron. Perchlorate is manufactured in the United States and is used as the primary ingredient of solid rocket propellant. Perchlorate wastes from the manufacture and or improper disposal of perchlorate-containing chemicals are frequently detected in the soil and water. Levels of perchlorate have been detected in 58 California public water systems and in water samples from 18 states. The widespread water contamination by perchlo-rate and its potential to cause health effects in those consuming contaminated drinking water have led four US agencies the EPA, Department of Defense, Department of Energy, and National Aeronautics and Space Administration to request that the US National Academy of Sciences convene a study on ''Toxicological Assessment of Perchlorate Ingestion.''

Occurrence in Food

Although the primary concerns from perchlorate contamination result from drinking water consumption, recent evidence has indicated that perchlorate may contaminate food items as well. A small survey of 22 lettuce samples purchased in northern California showed perchlorate contamination in 4 samples. A subsequent study of California lettuce showed detectable perchlorate levels in all 18 samples tested. The toxicological significance of such findings has not been established, but the studies clearly indicate that perchlo-rate can enter lettuce, presumably from growing conditions in which perchlorate has contaminated water or soil. Milk has also been shown to be subject to per-chlorate contamination. A small survey of seven milk samples purchased in Lubbock, Texas, indicated that perchlorate was present in all of the samples at levels ranging from 1.12 to 6.30 mg l. To put such findings in perspective, the State of California has adopted an action level of 4 mg l for perchlorate in...

Nonfood Uses

Aluminum compounds are widely utilized by industry. They are used in the paper industry, for water purification, in the dye industry, in missile fuels, in paints and pigments, in the textile industry, as a catalyst in oil refining, in the glass industry, and as components of cosmetic and pharmaceutical preparations. Of these, the uses within the cosmetic pharmaceutical industry are of particular significance since they provide the most likely sources of aluminum uptake by the body.

Other Religions

Jainism is an ascetic Asian religion whose adherents advocate ahimsa, or noninjury, both as an ethical and philosophical goal, and whose example has had a strong admonitory influence on non-Jains. The Jaina monastic community has a number of characteristic practices which evince an extreme regard for life. Monks carry a small brush with which they carefully sweep the floor before sitting or lying so as to avoid crushing any insects. They may wear masks to prevent inadvertent inhalation of small creatures, and strain their drinking water. Wild honey is avoided, as bees may be killed during its collection.

Hepatitis A

The most common type of hepatitis in children, hepatitis A is spread by eating food or drinking water contaminated with the hepatitis A virus that is shed in the stool. Formerly known as infectious hepatitis, hepatitis A tends to occur in cycles. In the United States, cases peaked from 1961 to 1971, declined, and then peaked again from 1983 to 1991 numbers dropped again after 1992. Food has been implicated in more than 30 outbreaks since 1983. It was implicated in 2004 in a large out break at a Pennsylvania Chichi's Restaurant, later traced to tainted scallions from Mexico.


Fluoridation The addition of fluoride to drinking water. Drinking water containing about 1 part per million of fluoride protects teeth from decay, and in some areas fluoride is added to drinking water to achieve this level. Naturally, the fluoride content of water ranges between 0.05 and 14ppm.
