Direct Photolysis Processes
Solar light is able to photoinduce the phototransformation of a lot of pesticides. In this chapter, we describe some of the most important photochemical processes leading to the chemical transformation of pesticides, in particular photodehalogenation, photoisomerization, photo-Fries and photo-Claisen. In each case, theoretical considerations are given and illustrated by examples taken from the literature. This chapter provides useful data for the understanding of the photoreactivity of a wide range of molecules of environmental concern.
