| Abstract: | "In order to survey the present pollution from volatile organic compounds in Baiyangdian Lake, 15 water samples were collected in March 2016, and analyzed for 54 VOCs by purge and trap gas chromatography-mass spectrometry. The distribution characteristics and health risk assessments were investigated, and the pollution from the VOCs was evaluated by a comprehensive pollution index. The survey showed that:1 in circle a total of 14 VOCs were detected in Baiyangdian water, with a 100% detection rate for dichloromethane, benzene, toluene, ethylbenzene, xylene, and 1,3,5-trimethylbenzene; xylene had the highest concentration with an average concentration of 564.9 ng .L(-1); and trichloroethylene had the lowest concentration with an average concentration of 3.3 ng .L(-1) and a detection rate of only 13.3%; 2 in circle the total concentration of VOCs in Baiyangdian water was between 423.0 and 4207.8 ng .L(-1), and benzene was the main pollutant, with its main source coming from the effluent from the upstream sewage treatment plant, the industrial wastewater, and the exhaust emissions of motor vehicles in the city; and 3 in circlethe health risk assessment showed that VOCs in Baiyangdian Lake did not produce carcinogenic and non-carcinogenic risks to humans, and the VOC comprehensive pollution index shows that the VOCs in the Baiyangdian Lake were at a clean level" |
