Abstract

The distribution and composition of the 17 organochlorine pesticides (OCPs) in selected samples were investigated with the gas chromatography coupled with Agilent triple quadrupole mass spectrometer (GC–MS). Only DDT has the highest detection rate of 100% within one year period. The total residual concentrations of 17 OCPs ranged from 0.1794 to 4.6479 ng/L, with a mean concentration of 2.7516 ng/L and1.3627 ng/L in dry and wet seasons, respectively. The highest concentration of the detected pesticides was far below the maximum allowable limits of drinking water sources standards of China and the threshold value of the US EPA. According to the indicators of the ratio values of (DDD+DDE)/DDT and α-HCH/γ-HCH, composition analyses and the source of pollution were also discussed in this study. It indicated that the origin of OCPs were historical residues and a recent usage or discharge of HCHs and DDTs into the Jinxiuchuan reservoir. In general, the concentrations of OCPs in the surface water body of Jinxiuchuan reservoir were much lower than others drinking water sources, and the risk was very low. Nevertheless, additional work including the monitoring investigation should be strengthened to guarantee the safety of drinking water.
