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: Arsenic is one of the most toxic and carcinogenic elements in the environment. This book brings together the current knowledge on arsenic contamination worldwide, reviewing the field, highlighting common themes and pointing to key areas needing future research. Contributions discuss methods for accurate identification and quantification of individual arsenic species in a range of environmental and biological matrices and give an overview of the environmental chemistry of arsenic. Next, chapters deal with the dynamics of arsenic in groundwater and aspects of arsenic in soils and plants, including plant uptake studies, effects on crop quality and yield, and the corresponding food chain and human health issues associated with these exposure pathways. These concerns are coupled with the challenge to develop efficient, cost effective risk management and remediation strategies: recent technological advances are described and assessed, including the use of adsorbants, photo-oxidation, bioremediation and electrokinetic remediation. The book concludes with eleven detailed regional perspectives of the extent and severity of arsenic contamination from around the world. It will be invaluable for arsenic researchers as well as environmental scientists and environmental chemists, toxicologists, medical scientists, and statutory authorities seeking an in-depth view of the issues surrounding this toxin.

Available in PDF, EPUB and Kindle. Book excerpt: Arsenic contamination of groundwater has been reported in over 20 countries worldwide where tens of millions of people are being exposed to excessive levels of arsenic in their drinking water, especially in countries of the Asian region, Bangladesh in particular. This study focusses on analytical techniques currently used for the estimation and speciation of arsenic in aqueous phase (soil and water) and in plant tissues; the uptake of arsenic by two commonly used vegetable crops (amaranth and silverbeet) using solution culture and pot culture studies; speciation-toxicity relationship of arsenic to plants; the nature of arsenic species in plant tissue and Bangladesh groundwater samples; and the effect of iron (Fe) on arsenic (As) uptake by plants and animals.

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 Speciation, Detection, and Quantification in Drinking Water Using High Performance Liquid Chromatography and Inductively Coupled Plasma Mass Spectrometry written by Brittany A. Almassalkhi and published by . This book was released on 2009 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary approach for the analysis of drinking water for heavy metals is through the United States Environmental Protection Agency's Methods 200.7 and 200.8 for Inductively Coupled Plasma Optical Emission Spectroscopy and Inductively Coupled Plasma Mass Spectroscopy, respectively. One of the most prominent heavy metals that has been of focus, and led to a decrease in the maximum contaminate level for drinking water, is total arsenic. It is, however, important to quantify the levels of each arsenic species in drinking water due to their different toxicities. In this study, a routine method to test, separate, and thereby quantify both the organic and inorganic arsenic species in real world samples was accomplished. Specifically four arsenic species: arsenite, arsenate, monomethylarsonate, and dimethylarsinate were separated in under six minutes through the use of ion-pairing reverse phase chromatography hyphenated with inductively coupled plasma mass spectrometry. Using tetrabutylammonium hydroxide as the ion-pairing reagent on a C18 column, the separation was obtained and utilized with real world samples that were tested and quantified.

Download or read book Field Speciation Method for Arsenic Inorganic Species written by Dennis A. Clifford and published by International Water Assn. This book was released on 2005-01-01 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inorganic arsenic (As) in drinking water is considered a human carcinogen with multiple sites of attack. There are numerous reports in the literature, based on past and ongoing experience in various countries in Asia and South America concerning the higher risks of skin, bladder, lung, liver, and kidney cancer that result from continued consumption of elevated levels of arsenic in drinking water. In ground waters, only inorganic arsenic in the form of arsenite [As III] and arsenate [As V] are significant. As III is much more toxic than As V. Moreover, due to the anionic character of As V in the drinking water, As V can be removed more easily than As III. Arsenic speciation of water samples changes over time, specifically, during transportation of samples to the laboratory and storage of samples for analysis due to redox reactions and photochemical oxidation. But, it is important to know the exact concentrations of the arsenic species in the drinking water at the source in order to develop proper treatment strategies, and for epidemiological studies. Therefore, arsenic-containing waters must be speciated immediately in the field or preserved for later speciation in the laboratory. Currently, there is no generally accepted (standard) method for field speciation or for preservation. This study describes the development of a reliable field-speciation method for inorganic arsenic species, and compares the new method with a recently developed USEPA preservation method.

Available in PDF, EPUB and Kindle. Book excerpt: There are more than 100 different arsenic with different characteristics in the soil-water-plant ecosystem. The identification and quantification of individual arsenic species is essential for understanding the distribution, environmental fate and behavior, metabolism and toxicity of arsenic. Due to the hazardous nature of arsenic, people have a high interest in the measurement of arsenic species. The reaction of the formation of arsenic speciation in the soil-water-plant environment is briefly studied. There is little information on methods used to quantify arsenic forms and species in contaminated soil, water and plant. The purpose of this article is to understand the available sample pretreatment, extraction, separation, detection and method validation techniques for arsenic speciation analysis of arsenic species in soil, water and plant. The performances of various sample preparation and extraction processes, as well as effective separation techniques, that contribute greatly to excellent sensitivity and selectivity in arsenic speciation when coupling with suitable detection mode, and method validity are discussed. The outlines of arsenic speciation techniques are discussed in view of the importance to the completeness and accuracy of analytical data in the soil-water-plant samples. To develop cheap, fast, sensitive, and reproducible techniques with low detection limits, still needed to confine research on arsenic speciation present in environmental matrices.

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.
