Heavy metals in soils continue to receive increasing attention due to the greater understanding of their toxicological importance in ecosystems, agriculture and human health, the growing scientific and public awareness of environmental issues and the development of even more sensitive analytical techniques to measure their concentrations accurately. Building on the success and acclaim of the first edition, this book has been thoroughly revised and updated and continues to provide a balanced and comprehensive review of the subject in two sections: the first providing an introduction to the metals'' chemistry, sources and methods used for their analysis; and the second containing chapters dealing with individual elements in detail. This volume is for soil scientists, research chemists, geochemists, agronomists, environmental scientists and professionals who deal with contaminated land. BJ. A. Contributors Professor B. J.
