Pesticides are enumerated among persistent organic pollutants (POPs) which make up the emerging contaminants in the aquatic environment. The risk inherent to pesticide pollution is prominent due to their low solubility in water, low sorption affinity to soils, toxicity, chemical stability, bioaccumulation and low biodegradability. The major sources of pollution by pesticides are drainage water from intensive agriculture, including water from washing pesticides containers and application equipment, and effluent from agricultural industries and pesticide manufacturing plants. The overall objective of the study is development of an effective treatment system for pesticide wastewater from a company producing chlorpyrifos. cypermethrin and chlorothalonil pesticides. There has been no work reported on complete treatment of pesticide wastewater containing these pesticides. The study was conducted in two phases. In phase I, five advanced oxidation processes (AOPs) (Fenton, UV photo-Fenton, solar photo-Fenton, UV/Ti02/H20 2 and FeUAC/H202) were applied for degradation of chlorpyrifos, cypermethrin and chlorothalonil pesticides in aqueous solution.
