Available in PDF, EPUB and Kindle. Book excerpt: The Society of Environmental Geochemistry and Health (SEGH) Second International Conference on Arsenic Exposure and Health Effects was held June 12-14, 1995 in San Diego, California. The conference was at tended by 152 people who heard 41 presentations on all aspects of arsenic research. The speakers represented 14 countries. Approximately 40 of the participants and speakers were from countries other than the US. The participants represented government, academia, industry and the interested public. The sponsorship ofthe conference is a good indicationofthe wide spread interest in the subject and the meeting. The sponsors, in addition to SEGH, were the US Environmental Protection Agency (US EPA), the Agency for Toxic Substances and Disease Registry (ATSDR), the Atlantic Richfield Company (ARCO), the Electric Power Research Institute (EPRI), the American Water Works Association Research Foundation (AWWARF), Kennecott Corporation, the American Smelting and Refining Company (ASARCO), and the International Council on Metals in the Environment (ICME). The funding was split approximately equally between industry (including industrial organizations such as EPRI) and government. In addition to the many fine presentations, the meeting provided a forum for scientists from different countries to compare experiences and share information. It also provided a forum for the discussion of both scientific and policy issues between representatives of various governmental bodies (at the local, state, and federal level) and representatives of various indus trial organizations. These discussions occurred both in the formal meetings and informal settings during the meeting.

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 Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 1999-07-14 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) has been considering a more stringent regulation of arsenic in water. A significant reduction in the maximum contaminant level (MCL) could increase compliance costs for water utilities. This book discusses the adequacy of the current EPA MCL for protecting human health in the context of stated EPA policy and provides an unbiased scientific basis for deriving the arsenic standard for drinking water and surface water. Arsenic in Drinking Water evaluates epidemiological data on the carcinogenic and noncarcinogenic health effects of arsenic exposure of Taiwanese populations and compares those effects with the effects of arsenic exposure demonstrated in other countriesâ€"including the United States. The book also reviews data on toxicokinetics, metabolism, and mechanism and mode of action of arsenic to ascertain how these data could assist in assessing human health risks from arsenic exposures. This volume recommends specific changes to improve the toxicity analyses and risk characterization. The implications of the changes for EPA's current MCL for arsenic are also described.

Download or read book Arsenic in Groundwater written by M. Manzurul Hassan and published by CRC Press. This book was released on 2018-03-08 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic-contaminated groundwater is considered one of the world’s largest environmental health crises, as more than 300 million people in more than one-third of countries worldwide are at risk of groundwater arsenic poisoning. This book addresses how arsenic in groundwater impacts human health by using the frameworks of natural sciences, social sciences, and health sciences in the context set by environmental and legal considerations. Arsenic in Groundwater: Poisoning and Risk Assessment examines the spatial, quantitative, and qualitative aspects on arsenic poisoning; for instance, using geographical information systems (GIS) to investigate the spatial discontinuity of arsenic-laced water in spatial and temporal dimensions to uncover patterns of variations over scales from meters to kilometers. Spatial risk mapping provides insight for academics, researchers, policy makers, and politicians on possible long-term strategies for arsenic mitigation. Qualitative methodological approaches uncover the hidden issues of arsenic poisoning on human health and the related social implications. The book also examines legal aspects, such as the right to safe drinking water, as well as an in-depth look at how community participation can shape public policy. Features: Describes arsenic poisoning from both the scientific and social science perspectives Includes technical insights drawn from GIS-based modeling for spatial arsenic discontinuity and spatial health risks of arsenic poisoning Provides a state-of-the-art review of the human health literature and cutting-edge scientific evidence for arsenic-related health and social implications Examines the environmental justice and legal issues of drinking water and its quality Presents environmental policy and public mitigation strategies with Public Participation GIS (PPGIS) related to arsenic contamination More than 2,000 references serve as valuable resources for various aspects of arsenic poisoning

Download or read book Arsenic Contamination in Asia written by Hiroshi Yamauchi and published by Springer. This book was released on 2018-11-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides valuable new insights into preventive measures for chronic arsenic poisoning, exploring the various causes, metabolism and toxicity, preventive drugs, functional foods and various methods for removing arsenic from contaminated water. The mechanisms of chronic arsenic poisoning vary between countries and regions, and the pathological difference, though reported on, is still only poorly understood. As large-scale chronic arsenic poisoning is concentrated in Asia, the contributions in this book were written by pioneers from Asia. Further, the management of removed arsenic has not yet become standardized, and this volume will serve as a vital source of new ideas by highlighting significant detoxification methods aimed at the disposal of arsenic. Arsenic Contamination in Asia represents a valuable sourcebook for scientists working in the fields of environmental health, occupational health, environmental science, fisheries science, agriculture, pharmacy, analytical chemistry, and clinical medicine. Also, beginning researchers, seasoned experts, and students who are seeking comprehensive information on the natural sciences including medicine will find this work thought-provoking, instructive and informative.

Download or read book Cancer Risks Associated With Elevated Levels of Drinking Water Arsenic Exposure written by F. J. Frost and published by IWA Publishing. This book was released on 2005-07-31 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2000, the USEPA reduced the drinking water arsenic MCL from 50 ?g/L to 10 ?g/L, affecting many U.S. community water systems. This study was conducted because of the large number of systems involved, the costs of compliance with the new standard, and the increasingly uncertain scientific basis for the regulation. Two large, recently conducted studies of low-dose drinking water arsenic exposures do not support the need for the regulation. The objective of this project was to examine whether lung and bladder cancer mortality or incidence rates are elevated in U.S. populations consuming drinking water that exceeds the new USEPA MCL for arsenic of 10 ?g/L. This study took place in two phases. In the first phase, the research team estimated the mean drinking water arsenic level of most U.S. counties and identified counties with a mean arsenic level >10 ?g/L and >20 ?g/L. In the second phase, they evaluated the relationships between lung and bladder cancer mortality (1950?1999) and incidence (1973?1999) in these populations using multi-level, hierarchical statistical models (i.e., MLwiN statistical software). The research team employed three approaches: (1) combining all cancer deaths for all ages across the decades (1950?1990) for which data were available, (2) conducting a subanalysis limited to the population age 50 years and older, and (3) combining cancer deaths for those decades (1960?1999) for which comparable census variables were available. Arsenic in drinking water at levels >10 ?g/L was not associated with greater mortality from bladder or lung cancer, nor was a higher level of arsenic associated with greater incidence of bladder or lung cancer. There was considerable variation between counties in both lung and bladder cancer mortality. County lung and bladder cancer mortality rates were strongly related to neighboring county lung and bladder cancer mortality rates. This relation suggests that making an adjustment for neighboring county cancer mortality rates controls the unmeasured confounding factors. Higher mortality rates for bladder and lung cancer were observed in counties designated as metropolitan and, for males, counties with a high percentage of persons employed in manufacturing. Lower mortality rates were observed in counties with higher mean educational levels and counties with a larger mean household size. These same covariate relationships were not apparent in the incidence analysis. This study did not find evidence of increased risk for lung or bladder cancer mortality or incidence from exposure to arsenic in drinking water. The findings are consistent with other recent studies of the health effects of low dose arsenic exposure and are inconsistent with the USEPA predictions of excess cancer risk from low dose arsenic exposure. Multi-level hierarchical analysis is a highly appropriate method for determining if areas with elevated drinking water contaminants have elevated health risks. It makes optimal use of existing data in a cost-effective analysis that adjusts for many covariates. It is an approach that should be considered for addressing future drinking water health effects issues. In particular, this study adds to the literature on low dose arsenic health effects, providing the first summary of mortality and cancer incidence in U.S. populations exposed to elevated drinking water arsenic. It should provide some reassurance to customers of many drinking water utilities. Originally published by AwwaRF for its subscribers in 2004.

Download or read book Arsenic Exposure and Health Effects written by Willard R. Chappell and published by Elsevier Science. This book was released on 1999 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Society of Environmental Geochemistry and Health (SEGH) Third International Conference on Arsenic Exposure and Health Effects was held from July 12-15, 1998 in San Diego, California. Several outstanding papers and posters generated lively discussion and debate not only about scientific issues but also about policy and regulatory issues. While developed countries are considering spending perhaps billions of dollars per year to reach concentrations of 10 micrograms per liter or less, countries like Bangladesh, India and China are trying to deal with much more severe, epidemic scale, arsenic problems with millions of dollars or less. Like its predecessors in 1994 and 1995, The Third SEGH International Conference on Arsenic Exposure and Health Effects (1998) continued the theme of global impact of arsenic. In addition, two new countries with significant arsenic problems, Inner Mongolia and Bangladesh, were represented. The Bangladesh problem could be larger than the one in West Bengal with a possible two-thirds of the population at risk. The conference also featured a session on mechanisms of cancer carcinogenesis. Several scientists presented their work on this important issue which is central to considerations of such questions as the shape of the dose-response curve at low doses. This latter issue was featured in the final session of the conference. Another session that was new and of great interest was on the treatment of victims of chronic arsenic poisoning. This was the most dynamic conference to date and this resulting monograph represents the state-of-the-art in arsenic research on a worldwide basis. It will contribute to the solution of the many problems caused by arsenic exposure throughout the world.
