Book Description
This is the second of two volumes that presents the results of a cooperative research effort between industry, academia, utilities to evaluate and demonstrate the treatment effectiveness of a wide range of technologies for arsenic removal. (Volume 1; ISBN: 1-58321-310-4; published Feb 2004) This volume focused on larger-scale in-situ demonstration testing of the major technologies reviewed in Volume 1, plus several additional technologies. Objectives were to describe the underlying chemical and physical controls over arsenic removal, consider the operational performance parameters and anticipate where improvements might occur. Sponsored by Arsenic Research Partnership, AWWRF, USEPA, and ACWA.

Book Description
The congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for arsenic research aimed at practical solutions of problems with considerable social impact, as well as focusing on cutting edge and breakthrough research in physical, chemical, toxicological, medical and other specific issues on arsenic on a broader environmental realm. The congress "Arsenic in the Environment" was first organized in Mexico City (As 2006) followed by As 2008 in Valencia, Spain and As 2010 in Tainan, Taiwan. The 4th International Congress As 2012 was held in Cairns, Australia from July 22-27, 2012 entitled Understanding the Geological and Medical Interface of Arsenic. The session topics comprised: 1. Geology and hydrogeology of arsenic; 2. Medical and health issues of arsenic; 3. Remediation and policy; 4. Analytical methods for arsenic; and 5. Special topics on "Risk assessment of arsenic from mining", "Geomicrobiology of arsenic", "Geothermal arsenic", "Rice arsenic and health perspectives", "Sustainable mitigation of arsenic: from field trials to policy implications", and "Biogeochemical processes of high arsenic groundwater in inland basins" Hosting this congress in Australia was welcome and valued by the local scientific communities. Australia is a mineral rich country where mining has generated significant economic benefit to its people. Unfortunately historical mining for base metals, gold and arsenic had led to environmental contamination of arsenic. Locally produced arsenical compounds were widely used as pesticides and in timber preservation. It is known that there are several thousands of cattle- and sheep-dip sites contaminated with arsenic in Australia. However, commonly observed symptoms of chronic arsenic poisonings such as those found in endemic-blackfoot areas are seemingly absent from these types of environmental contamination due to good quality of potable water supply. Does this fall in the classic argument of "the dose makes the poison"? This congress theme of "understanding the geological and medical interface of arsenic" will advance our knowledge in minimising the risk posted by this so-called number one prioritised contaminant – arsenic.

Book Description
Groundwater resources naturally contain high levels of arsenic in many parts of the world. Over the last two decades, the As-containing groundwater in South-East Asia has received much attention, but the situation is just as crucial in Latin America, where the number of studies is still relatively low, and the extent and severity of As-exposure in the populations has yet to be fully evaluated. This book aims to promote knowledge of the occurrence and genesis of As-rich groundwater in Latin America. It deals with constraints on the mobility of As in groundwater, As-uptake from soil and water by plants, As-propagation through the food chain, human health impacts, and As-removal technologies. Case studies are presented from Argentina, Bolivia, Chile, Ecuador, El Salvador, Mexico, Nicaragua and Peru, amongst others, and are viewed against the background of experience from other world regions. The book is a state-of-art overview of arsenic research in Latin America. It aims to create interest within the Latin American countries affected by the presence of arseniferous aquifers and to increase awareness among administrators, policy makers and company executives. It will also serve to inform the international scientific community, and improve international cooperation on arsenic in groundwater.

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.

Book Description
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.

Book Description
This work provides those involved in water purification research and administration with a comprehensive resource of methods for analyzing water to assure its safety from contaminants, both natural and human caused. The book first provides an overview of major water-related issues in developing and developed countries, followed by a review of issues of sampling for water analysis, regulatory considerations and forensics in water quality and purity investigations. The subsequent chapters cover microbial as well chemical contaminations from inorganic compounds, radionuclides, volatile and semi-volatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, as well as potential terrorist-related contamination. The last chapter describes the Grainger prize-winning filter that can remove arsenic from water sources and sufficiently protect the health of a large number of people. - Covers the scope of water contamination problems on a worldwide scale - Provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants - Describes the filter that won the $1 million Grainger prize and thereby highlighting an important approach to remediation
