Arsenic contamination has become a global phenomenon. With the development of advanced technological detection tools, more geographical areas have been identified. The people most affected are those in the poorer socio-economic groups. The research articles in this book have been contributed by scientists working in areas severely affected by these difficulties. The book includes an assessment of environmental health risks and economic impacts, and the technologies available for dealing with the problem. Written in a straightforward style, the book is designed to update knowledge on the dynamics of natural arsenic from the aquifers through groundwater to the food chain. It outlines efficient techniques for arsenic removal and inform administrators, policy makers and company executives, and aims to increase awareness of the problem.
