Phototransformation of Pesticides in Aqueous Solution,ated pesticides singlet or triplet states are involved in the scission of the carbon-chlorine bond, while the triplet state is often the first step for the reaction of the other pesticides. In this paper some reactions are presented to illustrate these two types of mechanisms.
