Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-11-26 with total page 241 pages. 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 Elements Principles and Corpuscles written by Antonio Clericuzio and published by Springer Science & Business Media. This book was released on 2000 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Elements, Principles and Particles, Antonio Clericuzio explores the relationships between chemistry and corpuscular philosophy in the age of the Scientific Revolution. Science historians have regarded chemistry and corpuscular philosophy as two distinct traditions. Clericuzio's view is that since the beginning of the 17th century atomism and chemistry were strictly connected. This is attested by Daniel Sennert and by many hitherto little-known French and English natural philosophers. They often combined a corpuscular theory of matter with Paracelsian chemical (and medical) doctrines. Boyle plays a central part in the present book: Clericuzio redefines Boyle's chemical views, by showing that Boyle did not subordinate chemistry to the principles of mechanical philosophy. When Boyle explained chemical phenomena, he had recourse to corpuscles endowed with chemical, not mechanical, properties. The combination of chemistry and corpuscular philosophy was adopted by a number of chemists active in the last decades of the 17th century, both in England and on the Continent. Using a large number of primary sources, the author challenges the standard view of the corpuscular theory of matter as identical with the mechanical philosophy. He points out that different versions of the corpuscular philosophy flourished in the 17th century. Most of them were not based on the mechanical theory, i.e. on the view that matter is inert and has only mechanical properties. Throughout the 17th century, active principles, as well as chemical properties, are attributed to corpuscles. Given its broad coverage, the book is a significant contribution to both history of science and history of philosophy.

Download or read book Uranie written by Camille Flammarion and published by Createspace Independent Pub. This book was released on 2012-07-30 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: I WAS seventeen. She was called Uranie. Was Uranie, then, a young girl, fair, with blue eyes, innocent, but eager for knowledge? No, she was simply what she has always been, one of the nine muses; she who presided over astronomy, and whose celestial glance animated and directed the spheral choir; she was the heavenly idea hovering above earthly dullness; she had neither the palpitating flesh, nor the heart whose pulsations can be transmitted through space, nor the soft warmth of humanity; but she existed, nevertheless, in a sort of ideal world, superior to humanity, and always pure; and yet she was human enough in name and form to produce in the soul of a youth a vivid and profound impression; to awaken in that soul an undefined and undefinable sentiment of admiration: almost of love.

Book excerpt: Any real understanding of where we stand scientifically today and where we are headed depends to a great extent on an awareness of how we reached those scientific achievements. The increased impact of science and technology on our lives makes such an understanding even more important. For this reason, this book is intended to provide information about the major works of science in the collections of the Library of Congress. These selected works are organized here by traditional scientific discipline and are treated in historical and, generally, chronological order. The contents contain chapters on: (1) astronomy; (2) botany; (3) zoology; (4) medicine; (5) chemistry; (6) geology; (7) mathematics; and (8) physics. A bibliography provides information about particular Library of Congress collections to which a book or manuscript may belong, as well as specific bibliographic information. Title translations are also included. (TW)

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.
