The model system CemoS
(Chemical Exposure Model System) was
developed for the exposure prediction of hazardous chemicals
released to the environment. Eight different models were
implemented involving chemicals fate simulation in air, water,
soil and plants after continuous or single emissions from point
and diffuse sources. Scenario studies are supported by a substance
and an environmental data base. All input data are checked for
plausibility. Substance and environmental process estimation
functions facilitate generic model calculations. CemoS is
implemented in a modular structure using object-oriented
programming.
