Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.
Download or read book Total Diet Studies written by Gerald G. Moy and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of low levels of toxic chemicals in their foods. Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace. The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study. Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.

Download or read book Modern Approaches to Terminological Theories and Applications written by Heribert Picht and published by Peter Lang. This book was released on 2006 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises contributions originally presented at the 15th European Symposium on Languages for Special Purposes held at the University of Bergamo on 29 August - 2 September 2005. The volume is divided into four parts: Approaches to Terminological Theories; Terms in Discourse; Knowledge Elicitation, Ordering and Management; Term extraction and terminographical work. The research presented in the various contributions to this volume clearly indicates that terminology as an inter- and transdisciplinary field of knowledge is firmly developing its theoretical foundations and practical applications in accordance with and within the framework of its overall goal: to ensure and to augment the quality of communication with professional content.

This book was released on 2011-03-02 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: La France, troisième consommateur mondial de produits phytosanitaires, est confrontée à la remise en question de leur utilisation. Plusieurs raisons y concourent : la prise de conscience des impacts sur l'environnement, voire sur la santé humaine, le renforcement des réglementations qui encadrent leur emploi, la réduction du nombre de produits autorisés et efficaces. C'est dans ce contexte que les ministères chargés de l'Agriculture et de l'Environnement ont demandé à l'Inra et au Cemagref de réaliser une expertise scientifique collective faisant le point sur les connaissances disponibles concernant les conditions d'utilisation des pesticides en agriculture, les moyens d'en réduire l'emploi et les impacts environnementaux. L'expertise examine l'utilisation actuelle des pesticides, les contaminations de l'environnement, les impacts sur les écosystèmes, les techniques et les aménagements de l'espace agricole susceptibles de réduire leur dispersion. Dans un deuxième temps, elle analyse la logique et les limites des systèmes de culture intensifs et spécialisés, qui favorisent de fait le développement des bioagresseurs (adventices, maladies et ravageurs) et peuvent donc difficilement s'affranchir d'un recours important aux pesticides. Par cet emploi répété et large, ces systèmes accélèrent aussi l'apparition de bioagresseurs résistants aux produits. Ensuite, sont examinés les techniques non chimiques de contrôle des bioagresseurs et l'intérêt des stratégies fondées sur la prévention, c'est-à-dire sur des systèmes qui réduisent les risques phytosanitaires. Enfin, elle étudie les conditions économiques qui renforcent actuellement la dépendance des systèmes agricoles vis-à-vis des pesticides, la nécessité de mettre en place une politique volontariste pour une réduction significative de leur emploi et les différents instruments réglementaires et économiques mobilisables pour élaborer une telle politique.
