Spectrum analysis on organic pollutants in drinking water out of Han River and Yangtze River water sources in Wuhan City

Objective To investigate the kinds of organic pollutants extracted from tap water out of Wuhan Han River and Yangtze River water sources.The results would help to provide more reliable data and evidence for monitoring pollution of Han River and the Yangtze River water and assessing the hazard of organic pollutants in drinking water out of the river water sources. Methods XAD-2 and XAD-8 equal proportion mixed resins (XAD-2/8) were used to concentrate organic pollutants contained in tap water out of Wuhan Han River and Yangtze River water sources during high flow and low water season.The organic pollutants were detected by GC/MS and the types of organic pollutants were compared in different water samples. Results The results of GC/MS showed that the amount of organic pollutants detected in tap water out of Han River water source during high flow and low water season was 110 and 102 respectively, the amount of organic pollutants detected in tap water out of Yangtze River water source during high flow and low water season was 79 and 95 respectively.The major kinds of organic compounds were diolefine, alkene, halogenated hydrocarbon, ester and phthalate. Conclusion The tap water out of Han and Yangtze River water sources was both polluted by organic matters, furthermore, the pollutants were found to be complex in variety and originated from extensive sources, which should arouse the attention of the government and the people.
