This two-volume series will describe the mechanisms that are operating on chemicals as thy move in the environment. Knowledge of these mechanisms is a vital component in performing a risk assessment. Volume I will deal with the physical and chemical properties of a material and how these influence the degradation and dissipating reactions. Volume 2 will address the transport of the chemical as it moves through the environment from the source to the final sink.

1. Environmental Systems Analysis, An Overview 2. Modeling Chemical Transport and Mass Balances in the Atmosphere 3. Modeling Chemical Transport in Lakes, Rivers, and Estuarine Systems 4. Nonpoint Source Pollution Models for Chemicals 5. Risk Benefit Analysis for Chemical Exposure
