Description:
Multimedia understanding of pollutant behavior in the environment is of particular concern for chemicals that are toxic and are subject to accumulation in the environmental media (air, soil, water, vegetation) where biota and human exposure is significant. Multimedia simulation modeling involves the simultaneous tracking of environmental stressors from a source through air, water, and soil to locations where human populations or ecological components may be exposed. By estimating realistic and technically valid distribution of emissions under a variety of scenarios, multimedia-based simulation models can be useful screening-level tools that can help both regulatory agencies and industry develop the best operating and control strategies to reduce risks. The purpose of this paper is to review the several approaches to multimedia modeling technology and to evaluate selected multimedia simulation models. First, a general comparison of the available multimedia modeling approaches is presented. Detailed evaluations of model components and capabilities are also presented for selected models. Significant differences in model capabilities as well as useful features of each of the models are identified; models differ with respect to environmental processes included and the mathematical formulation and assumptions related to the implementation of solutions. In addition, simulations were performed to investigate formulations and functions of the model by benchmarking analysis. Model capabilities and limitations of the state-of-the-art environmental multimedia modeling technology are also discussed from a user's point of view.
