Contamination of drinking water is a worldwide problem, and ongoing work is taking place across the globe to address the issues affecting this precious commodity. Focussing on the presence of heavy metals in water, this book addresses the opportunities and challenges of this important area of research. Written and edited by experts working within the area the book highlights new techniques and research methodologies used to treat the widespread issue of dissolved heavy metals in drinking water supplies. The text covers a wide range of topics, including biofilterations, use of nanotechnology against heavy metals, removal of heavy metals using industrial and agricultural waste, use of surfactants, soil degradation and removal of dyes and pigments from industrial effluents. Providing an up-to-date treatise on this developing field, this text will be essential reading for water and environmental scientists, toxicologists, biochemists and regulators, and anyone interested in the treatment and decontamination of the World's drinking water supplies.
