Appendix 1: Physical constants of some organophosphates. Appendix 2; Calculations for adsorption and leaching. Information concerning the fate of pesticides after application in the environment is useful to research workers concerned with safe and effective use. It is important to know whether a compound will persist or whether it will be inactivated. Frequently, persistence is desirable for sustained control; for many uses, however, rapid detoxification of the compound may be desirable to avoid cumulative effects. Disappearance of pesticides takes place by leaching, volatilization, adsorption, decompositino, or metabolism; and the use to which a particular pesticide is best suited may depend on the effects of one or more of these processes. This review is primarily concerned with the metabolism and decomposition of pesticides. The importance of these processes is apparent upon consideration of the facts (1) that the duration of toxic action can be related to the rate and manner in which the compound is metabolized; (2) that the rate of elimination from the body is dependent upon the physico-chemical properties of the metabolic products ; (3) that the ability of the compound to react a site of action may be limited by the rate at which it is metabolized and the character of the metabolic products ; and (4) that the toxicity of a compound can be decreased or intensified upon conversion to a metabolite. These points indicate the importance of knowing the pathways of metabolism as well as the degree of accumulation of metabolic products in tissue. For a more practical standpoint, the identification and measurement of residue levels of pesticides and their metabolites is necessary in order to fully evaluate the effects of pest control programs on wildlife.
