Abstract

The micro-contamination of drinking water resources with pesticides is of great concern nowadays due to their persistence in the aquatic environment and potential adverse effects to human health. Among various water treatment processes, UV and UV-based advanced oxidation processes (AOPs) have gained great attention due to their effectiveness in bacteria inactivation and low yield of disinfection byproducts. This work reviews, in a comprehensive manner, the degradation of several classes of pesticides including organochlorines, organophosphates, carbamates, chloroacetamides and triazines by UV and UV-based AOPs. The degree of pesticide removal, reaction kinetics, degradation byproduct identification and possible degradation pathways, and evaluation of toxicity of degradation byproducts are covered and discussed.
