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.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

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 Analyse chimique des sols written by Clément Mathieu and published by . This book was released on 2003 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce manuel pratique présente un inventaire détaillé et raisonné des analyses chimiques des sols réalisées en laboratoire. La caractérisation des sols et la compréhension de leur dynamique nécessitent en effet, outre des interventions in situ, des mesures et des analyses en laboratoire, notamment par les méthodes dites " classiques ". Répondant aux besoins d'informations actualisées les concernant, ce volume décrit ces méthodes choisies en 14 rubriques qui abordent successivement, après avoir rappelé l'importance des prélèvements sur le terrain et de la préparation des échantillons de terre : les mesures du pH ; le dosage du carbone organique; le dosage de l'azote total ; le dosage de l'azote ammoniacal et de l'azote nitrique ; le dosage du calcaire total et du calcaire actif et la détermination du pouvoir chlorosant ; le dosage du gypse ; le dosage de la salinité totale; le dosage des sols solubles ; la mesure de la capacité d'échange cationique ; le dosage des cations échangeables ; le dosage de l'acidité d'échange ; le dosage du phosphore ; le dosage du fer, de l'aluminium et du manganèse ; le dosage des oligoéléments et des éléments traces. Chaque rubrique est introduite par un rappel des concepts et des définitions du domaine analysé. Ce rappel permet de fixer les limites des méthodes présentées, d'évaluer les avantages et les inconvénients de leur usage. Les auteurs s'appuient également sur leurs expériences de terrain diversifiées pour proposer des choix appropriés. Après avoir exposé les méthodes, le matériel nécessaire et les modes opératoires, ils présentent des résultats. Analyse chimique des sols s'applique à l'analyse des sols en régions climatiques tempérées, méditerranéennes, arides ou tropicales. II s'adresse aux chercheurs en sciences de la Terre, aux professionnels de l'agriculture, de l'aménagement du territoire, de la protection des milieux naturels et des laboratoires d'analyses agréés, intervenant dans le cadre de programmes concernant les ressources en sols, les productions agricoles, la conservation du milieu ou de programmes de recherche. II est également indispensable aux enseignants et étudiants en pédologie, en agronomie et en science de l'environnement.
