The Yangtze River and Jialing River are the drinking water sources in the main urban area of Chongqing, and the qualitative analysis of their organic pollutants has not been reported. Using solid-phase extraction-GC/MS technology to analyze the organic pollutants in drinking water source water in the main urban area of Chongqing, a total of 101 organic pollutants were detected, including 64 kinds of source water from Jialing River and 46 kinds of source water from Yangtze River. The main pollutants include: phthalates, esters, ketones, phenols, heterocycles and benzene and its derivatives. The source water of the Jialing River is more polluted during the dry season than in the wet season, and the concentration of organic pollutants is significantly higher than that in the source water of the Yangtze River; Compounds with higher detection rates are: bis(2-methylpropyl) phthalate, dibutyl phthalate (100%), 1-chloro-4nitro-benzene (60%), 1,1,3,3,3-Pentachloropropane (50%), 2,6-Di-tert-butyl-p-cresol (40%); In addition, a variety of thiophosphoric acids were detected in the water samples of Plant B during the dry period The highest single content of ester is 56.5μg/L.
