Aquatic Mesocosm Studies in Ecological Risk Assessment [Hardcover]

A Special Publication of the Society of Environmental Toxicology and Chemistry (SETAC)

Aquatic Mesocosm Studies in Ecological Risk Assessment discusses the methods currently used for conducting simulated field studies and provides a series of case histories in which mesocosm type studies have been used to assess the impact of pesticides on aquatic ecosystems. Specific chapters address the dosing and exposure components of such studies and how they influence experimental design. Advantages and disadvantages of various statistical designs are addressed in detail. Regulatory aspects of the design and interpretation of these studies are also covered. The book will be a superb reference for aquatic biologists, ecologists, toxicologists, environmental toxicologists, environmental chemists, and regulatory personnel.Introduction.
