Abstract
The Center for Exposure Assessment Modeling (CEAM) was established to meet the scientific and technical exposure assessment needs of the United States Environmental Protection Agency's Program and Regional Offices and the various state environmental agencies. To support environmental risk-based decisions concerning protection of air, water, and soil, CEAM provides proven predictive exposure assessment techniques for aquatic, atmospheric, terrestrial, and multimedia pathways for organic chemicals and metals. A wide range of analysis techniques is provided, ranging from simple desk-top techniques through computerized steady-state models to sophisticated, state-of-the art continuous simulation models. The paper reviews the capabilities of 12 environmental models for urban and nonurban nonpoint sources, conventional and toxic pollution of streams, lakes and estuaries, tidal hydrodynamics, geochemical equilibrium, and aquatic food chain bioaccumulation.
