There have been many reports regarding the concentrations of pesticides in environmental waters. In contrast, only a few studies of pesticide transformation products in water environments (PTPWs) could be found in the literature, which can be attributed to the lack of an established PTPW list. Pesticides sprayed in water environments are quickly degraded, producing PTPWs such as hydrolysates and oxidative degradation products. These PTPWs remain in surface water, and are then chlorinated in waterworks. Thus, monitoring PTPW concentrations in environmental waters, and studying PTPW removal in waterworks are important in order to provide chemically safe tap water. Thus, in the present study, a PTPW list consisting of 610 PTPWs of 145 pesticides reported in the Evaluation Reports published by the Pesticides Expert Committee, Food Safety Commission, and 73 PTPWs of 14 pesticides found by reviewing 12,269 scientific papers was compiled in order to promote monitoring studies of PTPWs in environmental waters and PTPW removal in waterworks.
