| 摘 要： | 对包河表层沉积物6个位点的样品中多环芳烃进行了研究,分析其含量、分布特征及其生态风险评价,并结合采样点的情况对其进行源解析,共检测出6种多环芳烃,含量范围为0~9. 50 ng/g。按城市分布情况来看,工业厂附近多环芳烃的含量相对较高。比值法和因子分析法结果显示,多环芳烃污染主要来源于煤炭的燃烧,目前包河表层沉积物中多环芳烃含量处于低风险水平,尚未对生物造成显著的负面影响.

| Abstract: | The paper presents a study of polyeyelie aromatie hydroearbons (PAHs) in the surface sediment samples collected from Baohe in Shangqiu. Their concentration,distribution and ecological hazards were analyzed. Moreover,their possible sources were discussed based on the conditions of sampling sites. The PAHs concentrations of sampling sites near industral factories are much higher than that from other sampling sited. The indexes of source identification indicated the main source of PAHs in the samples was combustion source,which included coal and wood inadequate combustion. Presently the concentrations level of PAHs in the study area belonged to low level ecological risk,which have not caused the marked negative influence on organism. |
