摘　　要：通过分析沈阳市城区11个代表性的大学校园室内和街道的灰尘样品的Pb含量,采用美国EPA健康风险评价模型,对沈阳市大学校园灰尘Pb污染状况进行了健康风险评价.结果表明,沈阳市校园灰尘在不同程度上受到了重金属Pb的污染.非采暖期,室内和街道Pb含量平均值分别为60.42mg·kg-1、64.66mg·kg-1;采暖期,室内和街道灰尘中Pb含量分别为89.66mg·kg-1、99.22mg·kg-1,均高于辽宁省土壤重金属元素的背景值.重金属非致癌风险顺序为采暖期大于非采暖期,低于风险阈值。The Pb content of indoor and urban streets dust samples in 1 1 typical university campuses was analyzed.Using the EPA health risk evaluation model,the health risk of the Pb pollution in university campuses of Shenyang was evaluated. The results show that, the dust in university campuses of Shenyang is contaminated by Pb in varying degrees.The average contents of Pb in indoor and street were 60.42 mg·kg-1 and 64.66 mg·kg-1 in non-heating period;and during the heating period,the contents of Pb in indoor and street dust were 89.66 mg·kg-1 and 99.22 mg·kg-1 ,which were higher than the background value of soil heavy metal elements in Liaoning Province.The order of non-carcinogenic risk of heavy metals is：heating period is greater than non-heating period,which is below the risk threshold,and has non-carcinogenic risk.
