This book focuses on the behavior and impact of trace metals in the environment by studying typical cases from China such as the Hetao Area of the Yellow River, Shanghai, and Nanjing. Based on samples and experiments on the behavior of pollutants, it systematically discusses the regulation of trace metals¿ distribution, accumulation, and migration, associated with the cause of formation demonstration. The author subsequently uses the acquired data to review the evolving trend of trace metal behaviors in natural systems (river or lake water, sediments, and soils), develops suggestions for the prevention of their negative effects, and devise treatments. Moreover, he proposes solutions to difficult research issues such as trace metal speciation extraction, and an analysis, along with operational procedures. Given its scope, the book will provide a valuable guide for researchers and engineers in relevant disciplines of the environmental sciences and engineering, and for environmental policymakers to consult in practices.

Dr. Hui Zhang works as a faculty member in School of Environmental Science and Engineering, Shanghai Jiaotong University. He have been on the subject of pollutant behavior in environment for near 30 years, with valuable achievements such as many books and papers.

As the PI of the Research Group of Pollutant Behavior Chemistry of Shanghai Jiaotong University, his recent interests mainly focus on the impacts of human activity in geo-chemical cycles of substances on water and soil quality change (trace metals, arsenic, nitrogen, phosphorus and persistent organic pollutants) in natural and engineered systems (water, soil, and pollutant treating systems). Favorite researches are in four main areas: (1) Metals, nitrogen, phosphorus in soil and sediment; (2) Arsenic geochemistry and health; (3) Behaviors and controlling for pollutants (inorganic and organic) in the treatment of sewage sludge; and (4) Inactivation remediation for the metal contaminated soil.
