CemoS 2 - Chemical exposure model System

What's it about?

Short introduction

The model system CemoS2 (Chemical Exposure Model System) was developed for the exposure prediction of hazardous chemicals released to the environment. It is essentially a re-implementation of the existing CemoS1, using the Java programming language. Whereas the model structure is almost identical to the previous prject, CemoS2 provides many additional features, such as automatic unit conversion or a 'wizard' guiding you through the process of running a model simulation.
Six different models were implemented involving chemical fate simulation in air, water, soil and plants after continuous or single emissions from point and diffusive sources. More models will follow.

Scenario studies are supported by a substance data base and an environmental data base. All input data are checked for plausibility. Substance and environmental process estimation functions facilitate generic model calculations. Users can easily add their own estimation functions.
CemoS is implemented in a modular structure using the object-oriented programming language Java. Advanced users can easily integrate their own models into the program.

Development

CemoS is a project work in the course of studies Applied Systems Science at the University of Osnabrück, running since March 2001.
CemoS was developed and programmed by Andreas Beyer, Jörg Klasmeier, Alexander Meyer, Christian Fiedler, Ba Kien Tran, Birgit Wippermann, Britta Tietjen and Johannes Witt.
