内容説明
This book provides a basic introduction to sediment-heavy metal interactions and how sediment chemical data can be used to address environmental questions and issues. It is designed to promote self-teaching and is written so that students and professionals with a minimum of formal training in the environmental sciences can understand it. The book addresses all of the major physical and chemical factors that control sediment-trace element chemistry, as well as sampling and sampling design, data manipulation, and data interpretation. Following in the steps of the successful first edition, which was used as a text for a three day short course for U.S. Geological Survey professionals interested in sediment trace chemistry and its application to water quality issues, A Primer on Sediment-Trace Element Chemistry, 2nd Edition is ideal for academics, geochemists, chemists, hydrologists, environmental lawyers, and water quality professionals needing a comprehensive introduction to this field.
