Behaviors of trace metals in environment : the pollution in regional and metropolis areas 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
