Dynamic Aspects of Pesticide Photodecomposition
The fact that sunlight wavelengths possess sufficient energy to effect photochemical transformations in organic molecules has created a great deal of interest in the environmental photochemistry of pesticides (Crosby and Li, 1969; Plimmer, 1970). Since those who conducted initial studies on this subject were faced with the problem of simulating natural conditions, many approaches were used--some apparently quite satisfactory and others with little or no relation to conditions encountered in nature. From our results and those reported in the literature, it has become increasingly evident that pesticide photochemistry is very dependent upon the environmental compartment in which the compound resides during irradiation.
