Full Description
Chemicals in the Environment: Fate, Impacts, and Remediation is devoted to the broad review of metals and organic compounds in the environment. The volume focuses on three main aspects of chemicals in the environment: 1) fate and transport in soil, sediment, water and air; 2) resulting environmental impacts in the environment, wildlife, and humans, and 3) remediation methodologies and applications. An introductory chapter examines the history of metals and
organic chemicals in the environment, exposure to these chemicals through food, air and water, identification of chemical hazards, process and scope of ecological impairment, fate and transport modeling, impacts and monitoring, and remediation methods.
