Fate of chemicals

There are numerous methods available to identify the potential for chemicals to cause both healtli conditions and adverse effects on tlie eiiviroiiment. These can include, but are not limited to, toxicology, epidemiology, molecular and atomic structural analysis, MSDS sheets, engineering approaches to problem solving, fate of chemicals, and carcinogenic versus non-carcinogenic healtli hazards...

Examples of models of the environmental fate of chemicals, utilizing partition coefficients and fngacities, are given in the works cited earlier, and also in Chapter 3 in Walker et al. (2000, 2006). 

The environmental fate of chemicals is determined by both chemical/physical and biological processes in turn, the operation of these processes is dependent on the properties of the environmental chemicals themselves. Polarity, vapor pressure, partition coefficients, and chemical stability are all determinants of movement and... 

In Chapter 3, the distribution of enviromnental chemicals through compartments of the gross environment was related to the chemical factors and processes involved, and models for describing or predicting environmental fate were considered. In the early sections of the present chapter, the discnssion moves on to the more complex question of movement and distribntion in the living environment— within individuals, communities, and ecosystems—where biological as well as physical and chemical factors come into play. The movement of chemicals along food chains and the fate of chemicals in the complex communities of sediments and soils are basic issues here.

This symposium concerns models for predicting the fate of chemicals in the environment. Strictly speaking, the topic of this paper does not fall into the usual definition of fate models. However, every fate model has at least one source term. Although the source term for one fate model may be the output of another fate model (as when air transport models provide the deposition rates that are the inputs to an aquatic fate model), the chain always has to be traced to the original sources, whether they are natural or associated with human activities.
