摘要

摘要: 为明晰克鲁伦河流域地下水饮用水水源中挥发性有机物(volatile organic compounds,VOCs)的污染特征和风险水平,采用吹扫捕集气相色谱质谱联用仪对2020年8月在克鲁伦河流域采集的12个水样(7个地表水、5个地下水)进行分析,并采用美国国家环境保护局(US EPA)推荐的健康风险和生态风险评价模型对VOCs风险进行评价。结果表明:研究区域水体中VOCs污染程度较低,总体呈现地下水略高于地表水的状况;12个采样点均有VOCs检出,其中1,1-二氯乙烷、2,2-二氯丙烷、1,2-二氯丙烷、1,3-二氯丙烷、1,1-二氯乙烯检出率为100%;检出的VOCs中,1,3-二氯丙烷浓度最高,为1 186.44~4 677.97 ng/L,平均值为2 524.01 ng/L,邻二甲苯浓度最低,平均值仅为0.99 ng/L;各采样点无非致癌健康风险,致癌健康风险在可接受范围内,对水生生物有中等强度生态风险。

Abstract: In order to clarify the pollution characteristics and risk levels of volatile organic compounds (VOCs) in the groundwater drinking water sources of Klulun River Basin, a purge and trap gas chromatograph-mass spectrometer was used to analyze the pollution in the Klulun River in August 2020. Twelve water samples (7 surface water and 5 groundwater) collected in the basin were tested and analyzed, and the health risk and ecological risk assessment models recommended by US EPA were used to assess the risk of VOCs. The results showed that the degree of VOCs pollution in the water bodies of the study area was low, and the groundwater was generally slightly higher than the surface water. VOCs were detected in 12 sampling points, including 1,1-dichloroethane, 2,2-dichloropropane, 1,2-dichloropropane, 1,3-dichloropropane and1,1-dichloroethylene, and the detection rate of these VOCs were 100%. Among the detected VOCs, the concentration of 1,3-dichloropropane was the highest, with an average value of 2 524.01 ng/L, ranging from 1 186.44 to 4 677.97 ng/L; the concentration of o-xylene was the lowest, with an average value of only 0.99 ng/L. There was no non-carcinogenic health risks at each sampling site, the carcinogenic health risks were within an acceptable range, and there was moderate ecological risks to aquatic organisms.
