In order to achieve viable solutions to present-day environmental problems, professionals must understand the spatial and temporal links which exist between the different environmental compartments of biota, air, water, and land and aquatic sediments. This book explains many of the seminal theories used to identify links and predict the movement of natural and anthropogenic chemical compounds among environmental compartments. Theories are presented within the context of laboratory and field examples. Examples are given for many issues of public concern. New insights into theories regarding accumulation of contaminants such as PCBs are presented, challenging the passive acceptance of previously held dogma. The book is primarily for university education, but is also intended as a resource for environmental scientists and policymakers. To encourage self-study a number of exercises are incorporated in the text and two demo models are provided on a diskette, one showing radionuclide transport from dumped nuclear waste in the Kara Sea, the second illustrating the role of biodiversity in coastal zone management.
Any concentration of a substance measured in a living or non-living system results from its distribution among all of the environmental compartments: air, water, sediments, and biota. The transfer of a substance from one compartment to another is regulated by physical forces and the chemical properties of the substance and also those of the compartments. When transfer processes are nearly constant in time, a substance will achieve predictable equilibria distributions. It is of utmost importance that students, environmental scientists, and policymakers understand the basic processes which control the distribution of a substance in order to interpret measurements obtained from within a limited number of compartments.
This book explains how to identify compartmental links, evaluate distributions and predict movements of natural and anthropogenic substances in the environment. It is directed toward university education and is also intended as a resource for environmental professionals. The book contains exercises/answers and a disk.
