Abstract
The fate of toxic chemicals in the aquatic environment is determined by two factors: their reactivity, and the rate of their physical transport through the environment. All mathematical models of the fate of toxic chemicals are simply useful accounting procedures for the calculation of these processes as they become quite detailed. To the extent that the biological, chemical, and physical reactions and transport of toxic substances can be accurately predicted, their fate and persistence and the inevitable exposure to aquatic organisms can be modeled. Several models exist to estimate the fate and transport of toxic chemicals in lakes, rivers, and estuaries. Because of the inherent complexities of transport, estuarine modeling has not advanced as far as the others. In this chapter, transport of chemicals in the aquatic environment was described, and simplifications of the mass balance equations were developed. In some cases considerable insight can be gleaned from a simplified approach. The required level of model complexity depends on the user 's needs, expertise, and data base. Two examples of some ' first-cut ' approximations to chemical fate and transport illustrated the utility of this approach. (See also W87-08670) (Lantz-PTT)
