Demonstrates how the chemical structure of organic compounds influences the molecular interactions which control transfer and reaction processes in the natural environment. Thoroughly explains how to quantify these processes using the principles of chemistry, physics and biology in a macroscopic environmental system. Focuses on the behavior of major synthetic organic chemicals introduced in large quantities into the environment. Contains more than 100 illustrations, an extensive bibliography and useful reference material such as constants, units and equations. Serves as a text for introductory courses in environmental organic chemistry as well as a source of information for the professional concerned with risk and hazard assessment of organic chemical pollutants in the environment.
