Why Model Chemical Exposure?Chemicals are either destroyed by use and thus producing degradation compounds, or released into the sewers and the air, or dumped, or incinerated after use. A small, but increasing fraction is used again (recycled). Compounds released from the technosphere usually enter the biosphere.

Transport and Transformation Processes important processes are transport, e.g. flowing with a river and reaction, e.g. photodegradation. We now will consider these processes in more detail. At first, the physical transport processes of diffusion, ad/convection and dispersion are described, followed by chemical reaction processes.

Multi-Media Modelseasurements of chloroorganic pesticides like DDT and Dieldrin could be explained by their dispersive use. However, other compounds like PCBs which are solely used in closed devices were also found ubiquitously. This observation led to the recognition that almost all chemicals have a tendency to be d
