ABSTRACT
In Chapter 3, the distribution of environmental 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 discussion moves on to the more complex question of movement and distribution 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.
