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.

Available in PDF, EPUB and Kindle. Book excerpt: The main focus of Arsenic in Groundwater: Poisoning and Risk Assessment is to explore the untold stories of groundwater arsenic in view of its poisonous nature for human health, social implications, exposure and risk assessment, worldwide concentrations with space-time dimension, micro level GIS application in spatial arsenic concentration, policy response and mitigation options, and water right and legal issues of safe drinking water. There are very few books on arsenic issues and almost all the books are mainly based on geology, geochemistry and health issues. There is a gap in spatial, social and legal issues of arsenic toxicity, and the lack of literature on GIS-based modeling for spatial risk of arsenic contamination is a serious methodological limitation. Therefore, this book is a departure for health geography with a social science and legal context. The book deals with the arsenic issue within a social science point framework, with the context being set by environmental and legal considerations. Due consideration is given to the methodological issues of spatial, quantitative and qualitative enquiries on arsenic poisoning, for instance using GIS to investigate the distribution of arsenic-laced water in space-time to uncover the pattern of variations over scales from metres to kilometres. The production of spatial risk maps provides an indication to researchers, policy makers, and politicians of possible long-term strategies of mitigation. Qualitative methodological approaches uncover the hidden issues of arsenic poisoning on human health and their social implications as well as their coping strategies and adaptation in the face of community and in-family ostracism.

Download or read book Best Practice Guide on the Control of Arsenic in Drinking Water written by Prosun Bhattacharya and published by IWA Publishing. This book was released on 2017-07-15 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic in drinking water derived from groundwater is arguably the biggest environmental chemical human health risk known at the present time, with well over 100,000,000 people around the world being exposed. Monitoring the hazard, assessing exposure and health risks and implementing effective remediation are therefore key tasks for organisations and individuals with responsibilities related to the supply of safe, clean drinking water. Best Practice Guide on the Control of Arsenic in Drinking Water, covering aspects of hazard distribution, exposure, health impacts, biomonitoring and remediation, including social and economic issues, is therefore a very timely contribution to disseminating useful knowledge in this area. The volume contains 10 short reviews of key aspects of this issue, supplemented by a further 14 case studies, each of which focusses on a particular area or technological or other practice, and written by leading experts in the field. Detailed selective reference lists provide pointers to more detailed guidance on relevant practice. The volume includes coverage of (i) arsenic hazard in groundwater and exposure routes to humans, including case studies in USA, SE Asia and UK; (ii) health impacts arising from exposure to arsenic in drinking water and biomonitoring approaches; (iii) developments in the nature of regulation of arsenic in drinking water; (iv) sampling and monitoring of arsenic, including novel methodologies; (v) approaches to remediation, particularly in the context of water safety planning, and including case studies from the USA, Italy, Poland and Bangladesh; and (vi) socio-economic aspects of remediation, including non-market valuation methods and local community engagement.

This book was released on 2004 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: A working group of 23 experts from 13 countries met in Lyon to evaluate the evidence for carcinogenicity of arsenic (mostly naturally occurring) as a contaminant of drinking-water, and of the water-disinfectant chloramine. The working group also evaluated or re-evaluated four chlorination by-products found in drinking-water, namely chloral hydrate, di- and trichloroacetic acids, and 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (also known as MX). High-level exposure to arsenic in drinking-water occurs in some regions such as China, Latin America, Bangladesh and West Bengal. The Working Group reviewed epidemiological studies of human cancer (mainly ecological studies in Taiwan and Chile, and several case-control and cohort studies) in relation to arsenic in drinking-water. Arsenic in drinking-water (primarily inorganic, as arsenate and to a lesser extent arsenite) was evaluated as carcinogenic to humans (Group 1) on the basis of sufficient evidence for an increased risk for cancer of the urinary bladder, lung and skin. Studies on inorganic arsenic in experimental animals provided limited evidence for its carcinogenicity, but sufficient evidence was found in experimental animals for the carcinogenicity of dimethylarsinic acid (an organic form of arsenic), which produced urinary bladder tumours in rats and lung tumours in mice after oral administration.

Available in PDF, EPUB and Kindle. Book excerpt: Elevated levels of arsenic (As) in soils and water around the world are both a significant human health and environmental hazard. With increasing global water demands, there is a requirement to further the understanding of the biogeochemical cycling of As from soils and sediments. This thesis focussed on exploring the environmental controls on the occurrence and subsequent mobility of As in a range of natural environments. Arsenic was found to undergo mobilisation from both river sediments and upland peats under changing environmental conditions. The transport of As was found to be correlated with both iron (Fe) and organic carbon (OC), however temporal changes in both sediment/soil composition and movement of water through catchments have a important role in controlling the ultimate transport of As within the environment. A range of investigative methods were employed to study the occurrence and mobility of As within the river sediments of the Allier and Loire Rivers (France), including sequential extraction procedures and batch incubation studies. Arsenic was associated with the reducible phases of sediments, indicating the major role of Fe(oxy)hydroxides in the storage of As in river sediments. In addition to the presence of labile As, the rapid release of As was dependent on the initial sediment composition. Temporal changes in sediment composition may therefore play an important role in controlling the movement of As within fluvial systems. The combination of lead (Pb) and strontium (Sr) isotopic analysis with sequential extraction studies of sediments from the Loire and Allier Rivers was able to determine the relative dominance of granites and basalts within the sediments. This approach provided a first order study on which to better understand the mineral origins of the sediments. The analysis of multiple Pb isotopes was able to eliminate possible anthropogenic contribution to contamination within the sediments, confirming the importance of geogenic cycling of As within the rivers. Information on the origin of mineral formation was obtained through 87Sr/86Sr isotopic analysis, with the formation of Fe-minerals not occurring uniformly along the course of the rivers. While the Sr within the sediment phase targeting well-crystallised Fe(oxy)hydroxides was in equilibrium with the sampled river water, the formation of amorphous Fe minerals was likely occurring in waters upstream of the study sites, within the Massif Central. Total concentration profiles peat from two subcatchments within the Peak District (United Kingdom) provided evidence for both the retention and post depositional movement (PDM) of As within the solid phase, dependent on local conditions. For the first time, the partitioning of As was determined within ombrotrophic peat, and found to be in contrast to Pb, with oxidisible As (likely associated with organic matter) dominating, while Pb was found predominantly within the reducible sediment phase. High temporal resolution monitoring of the organic-rich streamwater draining the peat showed the transport of As was variable, with As found largely in the soluble form despite extensive peat erosion. The evidence for PDM, and the subsequent soluble transport of As demonstrated the importance of biogeochemical processes in releasing As from the solid phase. Once mobilised, both the ratio of Fe:OC and the form of Fe were found to be factors controlling transport of As, with the flushing of stored porewaters an important contribution to As transport from the peat. Despite OC-rich waters, the occurrence of high concentrations of Fe may dominate control of As within the aqueous phase. At relatively high (>0.2) Fe:OC ratios, the particle size distribution of As was closely correlated with that of >1um Fe, although the presence of dissolved and colloidal As was found even within these waters. Given the temporal variability of As transport within the streams, knowledge of the mixing order and ratio between Fe, OC, and As within natural waters may be required for prediction of the mobility and ultimate fate of As.

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
