| 摘 要： | 根据浑河水环境中多环芳烃的监测数据,运用主成分分析法(Principal Component Analysis)对水体中16种多环芳烃的分布情况和来源进行了分析.通过因子得分对浑河14个断面污染状况进行综合排序,发现七台子、七间房PAHs污染最严重,主要以交通和炼焦源为主;其次为东洲河,主要为石油类产品和化石燃料中低温燃烧源.而作为沈阳市的污水排放渠的于台断面中多环芳烃污染较轻.表明浑河流域水体中多环芳烃污染来源于面源污染,主要由大气沉降、路面上残留的汽车燃烧产物被雨水冲刷后带入水体所致.

| Abstract: | Principal Component Analysis （PCA） was applied to analyze the distribution and sources ot PAHs in the surface water from the Hun River. Integrated evaluation results of water quality at the 14 monitoring sections showed that PAHs pollution at Qitaizi and Qijianfang monitoring section were the most heaviest, and the major source contributions derived from traffic emissions and coke oven. Dongzhou monitoring section was the second, where the PAHs primarily from petroleum and incomplete combustion source. While the Yutai section was the lightest. These results indicated that the PAHs pollution in surface water of Hun River mainly derived from agricultural ／urban runoff and atmospheric deposition. |
