Papers from the 7th Conference on the Biogeochemistry of Trace Elements

The presence of arsenic in the environment causes severe health risk with increased incidences of cancer in may regions of the world, making it to a global problem. Today, the greatest part of the world population depends on groundwater for drinking, and in many regions groundwater contains arsenic above the drinking water standards and thus raise public health concern in both developed and developing countries. The book gives a state-of-art overview of the recent developments in the fields or arsenic research. it deals with the geogenic and anthropogenic arsenic sources, the occurrence of arsenic and their distinct species in soils, and ground- and surface waters in naturally and anthropogenically affected ecosystems, and discusses mobilization, and transport as function of changing geochemical conditions. Health effects, resulting from human arsenic uptake through arsenic-contaminated drinking water and food are addressed. The book comprises chapters outlining innovative approaches for arsenic removal from contaminated soil using phytoremediation, and low-cost remediation methods fro removal of arsenic from contaminated water using locally available sorption materials. The contribution ion this book include a wide range of considerations of arsenic from the molecular to the landscape scale. It concludes global and regional perspectives of the ext3nt and severity of arsenic contamination in difference sectors of human life and the need of an increase of the attention to this problem.Bhattacharya, Prosun is the author of 'Papers from the 7th Conference on the Biogeochemistry of Trace Elements ', published 2007 under ISBN 9780444518200 and ISBN 0444518207.
