Book Description
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 Description
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.

[email protected]) Security issues related to desertification in the Mediterranean Region were the subject of a special NATO workshop held on 2-5 December 2003 at the Museum of Sciences Principe Felipe in Valencia, Spain. This workshop was organized by the U.S. Environmental Protection Agency (Las Vegas, Nevada, USA), Centre for Desertification Research (Valencia, Spain), and the Desert Research Institute (Reno, Nevada, USA) on behalf of the NATO Science Committee and the NATO Committee on the Challenges of Modern Society (Public Diplomacy Division). Additionally, the European Society for Soil Conservation participated as a collaborating institution. Other participating institutions included the Spanish Ministry of Environment, Generalitat Valencia (Department of Territory and Housing), the Secretariat of the United Nations Convention to Combat Desertification and the City of Art & Sciences of Valencia which hosted the Meeting.

Book Description
This edited book, Soil Contamination - Threats and Sustainable Solutions, is intended to provide an update on different aspects of soil contamination exerted by a multiplicity of exogenous and endogenous causes. We hope that this book will continue to increase information from diverse sources and to give some real-life examples, extending the appreciation of the complexity of this subject in a way that may stimulate new approaches in relevant fields.

Book Description
This collection of five essays by Germanys most prominent and influential social thinker both links Luhmanns social theory to the question What is modern about modernity? and shows the origins and context of his theory. In the introductory essay, Modernity in Contemporary Society, Luhmann develops the thesis that the modern epistemological situation can be seen as the consequence of a radical change in social macrostructures that he calls social differentiation, thereby designating the juxtaposition of and interaction between a growing number of social subsystems without any hierarchical structure. European Rationality defines rationality as the capacity to see the difference between systems and their environment as a unity. Luhmann argues that, in a world characterized by contingency, rationality tends to become coextensive with imagination, a view that challenges their classical binary opposition and opens up the possibility of seeing modern rationality as a paradox. In the third essay, Contingency as Modern Societys Defining Attribute, Luhmann develops a further and probably even more important paradox: that the generalization of contingency or cognitive uncertainty is precisely what provides stability within modern societies. In the process, he argues that medieval and early modern theology can be seen as a preadaptive advance through which Western thinking prepared itself for the modern epistemological situation. In Describing the Future, Luhmann claims that neither the traditional hope of learning from history nor the complementary hope of cognitively anticipating the future can be maintained, and that the classical concept of the future should be replaced by the notion of risk, defined as juxtaposing the expectation of realizing certain projects and the awareness that such projects might fail. The book concludes with The Ecology of Ignorance, in which Luhmann outlines prospective research areas for sponsors who have yet to be identified.
