Download or read book Arsenic Contamination in the World written by Susan Murcott and published by IWA Publishing. This book was released on 2012-09-30 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic Contamination in the World: an International Sourcebook provides a global compendium of cited arsenic occurrences in the world as they affect public health. This book details arsenic contamination by source, region and arsenic-affected country. Arsenic is identified in 105 countries and territories, representing a larger database than any previous published work. Sources of arsenic contamination are categorized as Anthropogenic, Geogenic, Volcanogenic, Coal, Mining and Petroleum-related. National, regional and international maps locate the affected areas and populations. A synthesis of critical country information includes an estimate of the exposed population of 226 million people worldwide. This reference work is an indispensable tool for medical doctors, public health workers, scientists, water experts, governments, industries, non-profit organizations and communities in identifying site-specific arsenic contamination. An extensive bibliography of peer-reviewed literature gives the reader important arsenic contamination locations as the first step towards remediation. This Sourcebook is updatable via an on-line annex which provides up-to-date information on new arsenic occurrences and developments. We invite readers to participate in updating this database at: http://www.iwawaterwiki.org/xwiki/bin/view/Articles/ExecutiveSummaryofArsenicContaminationintheWorld By synthesizing the known occurrences of arsenic world-wide, this reference book offers an essential tool for understanding and addressing the global arsenic geological-public health interface.

Download or read book Arsenic Distribution Within the Sediments and Pore Waters of the Historical Mining impacted Belle Fourche and Cheyenne River Floodplains written by Bryce Daniel Pfeifle and published by . This book was released on 2011 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold mining operations in the Lead area of South Dakota directly discharged spent mine tailings into Whitewood Creek from 1876 until 1977. These tailings contained sulfide-bearing minerals including arsenopyrite, which composed 0.8 percent of the primary ore body. Physical and chemical processes have resulted in substantial transport and deposition of arsenic-enriched sediments along Whitewood Creek, the Belle Fourche River, the Cheyenne River and Lake Oahe. It is estimated that 110 million metric tons of tailings are still contained within the Belle Fourche and Cheyenne river floodplains. Sediment pore-water dialysis chambers (peepers) were deployed over a two-week sampling period and their contents were analyzed for As and Fe speciation and other select trace element concentrations to determine temporal and seasonal influences associated with sediment redox geochemistry. Sediment cores were taken adjacent to the peeper deployment sites and underwent X-ray diffraction, ICP-EAS, Biolog microbial analysis, and sequential Fe and As extractions. Other field and lab analyses of the sediments and pore waters are further discussed within this document. The more heavily As-impacted Belle Fourche River sites had the greatest maximum pore water (2570 ug/1 at BF-V-1) and sediment (1010 ppm at BF-V2) As concentrations. Results show that pore water As concentrations appear to be primarily controlled by dissolution of iron oxyhydroxides resulting from reducing conditions, with As(III) and Fe(II) as the dominant aqueous species. Iron and AS sequential extraction results indicated stores of soluble metals are still present within the sediments. Their release into the pore water seems to be accelerated as the tailings-infused alluvial sediments are subjected to changing water levels as well as erosion and redeposition, allowing changes in the redox conditions to promote As and Fe dissolution. The fluctuation of redox conditions also seems to promote Fe transformation into more crystalline mineral structures, which reduces sorption site capacities and could allow As to become more inertly bound to the iron minerals. Microbial reduction of Fe and As does not appear to be a major dissolution trigger but could affect the speciation of As, especially within the Cheyenne River alluvial system, where microbial activity was greatest. Because of the heterogeneous and dynamic nature of these alluvial systems, their long-term biogeochemical stability in not likely.

Book excerpt: This book presents an overview of the chemistry, geology, toxicology and environmental impacts of arsenic, presenting information on relatively common arsenic minerals and their key properties. In addition, it includes discussions on the environmental impacts of the release of arsenic from mining and coal combustion. Although the environmental regulations of different nations vary and change over time, prominent International, North American, and European guidelines and regulations on arsenic will be reviewed. Includes information on recent environmental catastrophes (e.g. Bangladesh and China) A thorough discussion of the arsenic cycle, including the cosmological origin of arsenic Includes Appendices providing extensive glossary and measurement conversion tables

Download or read book Arsenic Water Resources Contamination written by Ali Fares and published by Springer. This book was released on 2019-07-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume brings together a 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 sheds light on this global environmental issue, and proposes solutions to aquatic 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. Part one of the book describes the issue of arsenic contamination in ground water and river basins, including its source and distribution in specific locations in India. Part two explains the routes of exposure to environmental arsenic, its transport in aquatic ecosystems, and the health risks linked to arsenic exposure in food and the environment. Part three addresses sustainable arsenic contamination mitigation strategies and policies, the socioeconomic, demographic, cultural and psychological aspects of arsenic contamination, and the potential applications of GIS and remote sensing in providing solutions. Part four concludes by discussing the role of local and regional institutions in water resources management for a variety of issues including but not limited to arsenic contamination, and presents a case study in the Indus river basin in Pakistan to propose future contamination mitigation strategies.
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-12-26 with total page 242 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.
