This report discusses the question of the potential long-term impacts of the accumulation and mobilization of toxic and environmentally harmful chemicals in the environment. This paper deals with the potential problems caused by long-term accumulations of chemicals in the environment, cites examples of economic costs of such occurrences, and defines the  means by which, under certain circumstances, such accumulations behave as "time bombs". The report gives examples of such behavior and discusses how chemical time bombs may be predicted.
