Document Summary

Substances that are released into the atmosphere, deliberately or inadvertently, from natural or anthropogenic sources and that have the potential to be toxic or cause harm. Four part process: release into the environment, transport into biota, with or without chemical transformation, exposure of one or more target organisms, response of individual organism, population or community. In order to control, regulate or remove sources of atmospheric pollution, a clear scientific understanding of the physical, chemical and biological processes involved is essential, with assessment and management of risk. Transport into biota of atmospheric pollutants and exposure of target organisms to atmospheric pollutants. Components of the model for which atmospheric pollution is most distinctive. Atmosphere as a medium for chemical or physical transformation. Atmosphere as a vector for local deposition into water or onto soil. Atmosphere as a vector for long range transport. Direct inhalation, entry through pores, stomates, or contact with skin.
