Environmental Chemistry of Arsenic


Book Description

With contributions from world-renowned experts in the field, this book explores developments in the transport kinetics, seasonal cycling, accumulation, geochemistry, transformation, and toxicology of arsenic. It details advances in the prevention and control of arsenic and arsenic compounds in the air, soil, and water and offers analytical methods for the detection and study of arsenic in the environment and human body. Providing bioremediation techniques for effective treatment of contaminated water supplies, the book discusses factors that influence the removal of arsenic from water as well as diurnal and seasonal variations in the arsenic concentration of surface water supplies.




Reviews of Environmental Contamination and Toxicology


Book Description

Reviews of Environmental Contamination and Toxicology provides detailed review articles concerned with aspects of chemical contaminants, including pesticides, in the total environment with toxicological considerations and consequences.




Biological Chemistry of Arsenic, Antimony and Bismuth


Book Description

Arsenic, antimony and bismuth, three related elements of group 15, are all found in trace quantities in nature and have interesting biological properties and uses. While arsenic is most well known as a poison - and indeed the contamination of groundwater by arsenic is becoming a major health problem in Asia - it also has uses for the treatment of blood cancer and has long been used in traditional chinese medicine. Antimony and bismuth compounds are used in the clinic for the treatment of parasitic and bacterial infections. Biological Chemistry of Arsenic, Antimony and Bismuth is an essential overview of the biological chemistry of these three elements, with contributions from an international panel of experts. Topics covered include: chemistry of As, Sb and Bi biological chemistry of arsenic biological chemistry of Sb and Bi arsenic and antimony speciation in environmental and biological samples arsenic in traditional chinese medicine arsenic in aquifers biomethylation of As, Sb and Bi uptake of metalloids by cells bismuth complexes of porphyrins and their potential in medical applications Helicobacter pylori and bismuth metabolism of arsenic trioxide in blood of the acute promyelocytic leukemia patients anticancer properties of As, Sb and Bi radio-Bi in cancer therapy genotoxicity of As, Sb and Bi metallomics as a new technique for As, Sb and Bi metalloproteomics for As, Sb and Bi Biological Chemistry of Arsenic, Antimony and Bismuth conveys the essential aspects of the bioinorganic chemistry of these three elements, making this book a valuable complement to more general bioinorganic chemistry texts and more specialized topical reviews. It will find a place on the bookshelves of practitioners, researchers and students working in bioinorganic chemistry and medicinal chemistry.




Arsenic in Drinking Water


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.




Arsenic Toxicity: Challenges and Solutions


Book Description

Arsenic (As) is a widely distributed element in the environment having no known useful physiological function in plants or animals. Historically, this metalloid has been known to be used widely as a poison. Effects of arsenic have come to light in the past few decades due to its increasing contamination in several parts of world, with the worst situation being in Bangladesh and West Bengal in India. This edited volume brings together diverse group of environmental science, sustainability and health researchers to address the challenges posed by global mass poisoning caused by arsenic water contamination. The book covers sources of arsenic contamination, and its impact on human health and on prospective remediation both by bioremediation and phytoremediation. Applications of advance techniques such as genetic engineering and nanotechnology are also discussed to resolve the issue of arsenic contamination in ground water and river basins. The book sheds light on this global environmental issue, and proposes solutions to remove contamination through a multi-disciplinary lens and case studies from Bangladesh and India. The book may serve as a reference to environment and sustainability researchers, students and policy makers. It delivers an outline to graduate, undergraduate students and researchers, as well as academicians who are working on arsenic toxicity with respect to remediation and health issues.




Arsenic


Book Description

This book is dedicated to the multifaceted description of the crucial issue of arsenic contamination and its effect on human health. From soil to man, this book describes the several steps from arsenic speciation in rocks, water and environment in general, through the contamination of rice-based foods in infants diet, up to the devastating effects on human health. The axis soil-food-health raises more issues than ever imagined and the book is aimed at linking all the interdisciplinary aspects involved while giving a complementary interpretation of the phenomenon. Medical geology has recently emerged as a new discipline trying to explain the events with an interdisciplinary approach and to solve the related problems for human health. Far from being exhaustive, this book is aimed at briefly addressing the 'arsenic issue' and concerns for human health while presenting the different techniques employed for arsenic removal, from natural or polymeric adsorbents to biological filtration.
