Fluoride in Drinking Water

ISBN: 030910128X

Languages : en
Pages : 531
Book Description
Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.

Book Description
In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparationâ€"including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.

Book Description
The objective of this research was to evaluate the effects of dietary heated fats from a commercial deep-fat frying operation and of cyclic fatty acids (CFA) on rat liver enzyme activity. The fats were partially hydrogenated soybean oil (PHSBO) used 4 days (4-MH) and 7 days (7-DH) for frying foodstuffs. Balanced diets containing these used fats were fed to rats for 10 weeks. In a second experiment, rats were pair-fed diets containing graded doses of 7-DH. In a third, 0.15% CFA diet was fed to animals. In a fourth, rats were pair-fed diet containing the 7-DH treated (T-7DH) with magnesium silicate which removes some polymers from the used oil. All four sets of experiments were conducted with control rats fed non-heated PHSBO (NH) diet. All diets were isocaloric with 15% fat. Animals fed 7-DH diet either ad libitum or by pair-feeding, showed significant increased contents of cytochromes P$sb{450}$ and b$sb5$ as well as increased activity of (EC 1.6.2.4) NADPH-cytochrome P$sb{450}$ reductase when compared to controls. The 4-MH diet group showed the same trends for cytochromes contents and reductase activity in comparison to controls. Similar results were obtained with CFA diet. The activities of (EC 2.3.1.21) carnitine palmitoyltransferase-I; (EC 1.1.1.42) isocitrate dehydrogenase; were significantly decreased in each case either ad libitum or by pair-feeding in comparison to controls. Significantly depressed activity of (EC 1.1.1.49) glucose 6-phosphate dehydrogenase was also noticed for these animals when compared to NH. Similar results were recorded when fed CFA diet to rats. In addition, liver and microsomal protein were significantly increased when the used oils were fed to rats either ad libitum or by pair-feeding in comparison to NH. Enlarged and fatty livers were noted. Similar results were obtained when fed CFA diet. Liver glycogen was significantly decreased when fed the used oils or CFA diets in comparison to controls. However, when animals were fed T-7DH diet, the activities of the enzymes were significantly improved.

Book Description
Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.
