Available in PDF, EPUB and Kindle. Book excerpt: From the Introduction With regard to nitrate and nitrite, the perceived hazards are to the ecological balance in rivers and lakes, and to human health. Increased nitrate levels in river water lead to increased growth of algae and consequent decrease in the level of biologically available oxygen (BAO). In extreme forms, the algae form unsightly blooms on the water surface, and the BAO level falls below that necessary to support fish and other animal life. At this extreme, there is little dispute that efforts should be made to restore the ecological balance, and this is best achieved by reversing the increase in nitrate concentration that caused the problem. The health hazards are less clear, but include the risk of methaemoglobinaemia in young infants and the possible risk of gastric cancer, particularly in certain high-risk patient groups. These health risks have led to legislation to control the exposure of humans to nitrate from drinking water and as a food additive . . . What can be done about this and how can the problem be solved (if, indeed, there is a problem)? It is normal practice to add nitrate and nitrite to food as a cosmetic and as a preservative. Is this necessary? If so, how much do we need to add? Are there alternatives? What effect does added nitrate have on total nitrate exposure of humans? . . . In this book, we have attempted to answer, or at least to give the background to, some of the questions. . . .

Download or read book Nitrate and Nitrite in Drinking Water written by and published by National Academies Press. This book was released on 1995-01-01 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Safe Drinking Water Act directs the U.S. Environmental Protection Agency (EPA) to establish national drinking-water standards for chemical and biological contaminants in public water supplies. The standards are to be set at concentrations at which no adverse effects on human health occur or are expected to occur from lifetime consumption, allowing a margin of safety; enforceable standards are standards that are feasible to achieve with the use of the best technology available. The standards are to be reviewed periodically to ensure continued protection of public health. Consistent with the requirement for periodic review, EPA asked the National Research Council to evaluate the current drinking-water maximum-contaminant-level goals (MCLGs) and maximum contaminant levels (MCLs) for nitrate and nitrite in public water supplies. The Subcommittee on Nitrate and Nitrite in Drinking Water, convened under National Research Council procedures, reviewed information on the occurrence and toxicity of nitrate and nitrite. The subcommittee evaluated this information in the context of the drinking-water standards for those substances and drew conclusions about the adequacy of the current standards to protect human health.

This book was released on 2018-02-25 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Occurrence and Distribution of Nitrates and Nitrites in Food, Feces and Urine In 1847 Felouze made use of the reaction between ferrous chloride and hydrochloric acid in the presence of nitric acid or the salts of nitric acid. These substances when heated together react with the formation of nitric Od6 and an oxidation of the ferrous chloride to ferric chloride, This method marks the real beginning of chemical methods for the determination of nitric acid and a short description of the Felouze mode of procedure is of interest. Felouze made up a solution of potassium per-manganate and determined its factor by means of piano Wire dissolved in hydrochloric asid in the absence of air. He then placed a weighed amount of this iron Wire ii a flask, added hydrochloric acid. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Nitrate Contamination written by Istvan Bogardi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.
Download or read book The Mediterranean Diet written by Richard Hoffman and published by John Wiley & Sons. This book was released on 2013-04-22 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent large-scale epidemiological studies have confirmed the pre-eminence of the Mediterranean diet for reducing the risk of primary and secondary heart disease and cancer. There is also increasingly convincing evidence for its protective value against diabetes, dementias and other age-related disorders, and for increasing overall longevity. The Mediterranean Diet: Health and Science is a timely, authoritative and accessible account of the Mediterranean diet for nutritionists and dieticians. It discusses the Mediterranean diet in the light of recent developments in nutritional biochemistry, disease mechanisms and epidemiological studies, and also provides advice on nutrition policies and interventions. The Mediterranean Diet: Health and Science opens with an overview of the Mediterranean diet, and this is followed by a survey of the latest epidemiological evidence for its health benefits. There is detailed nutritional information on olive oil, wine, fish, fruit and vegetables and other components of the Mediterranean diet, and this information is used to explain how the diet protects against a range of age-related diseases. The book emphasises the importance of understanding the Mediterranean diet in its totality by discussing the evidence for beneficial interactions between various components of the diet. There are also discussions of how agricultural practices, as well as food preparation and cooking techniques, influence the nutritional quality of the diet. The book concludes by discussing the social context in which the Mediterranean diet is eaten, and public health issues associated with adopting a Mediterranean diet, especially in the context of more northerly countries. Written by nutritional biochemist Richard Hoffman and a past President of the French Nutrition Society, Mariette Gerber, who between them have many years experience in this area, this exciting and highly topical boook is an essential purchase for all nutritionists and dietitians worldwide. Libraries in all universities where nutrition, dietetics and food science and technology are studied and taught should have copies of this excellent book on their shelves.
