This book is concerned with heavy metals, which are considered to be the most hazardous pollutants present in the water system. Heavy metals are extensively studied and their effects on human health are reviewed here. Although several adverse health effects of heavy metals are known for a long time, exposure to heavy metals continues and is even increasing in some parts of the world. This books deals with the source of heavy metals in the environment and possible mitigation measures for metal recovery. The technology available for the detection of heavy metals and the latest remediation techniques are also discussed in detail. In this way, the book also addresses general background to polymers and their composite materials for removal of specific toxic heavy metals from waste water. The different adsorption isotherm models and adsorption mechanism using biosorption methods are also described. The widespread applications of low-value agricultural products, ion-exchange, coagulation, precipitation, flocculation, ultra-filtration and electrochemical methods are mentioned. The book reviews the essential issues and will be of interest to academicians, research scholars and industries. It will be the precious resource for all undergraduate and postgraduate students at institutes and universities.
