摘　　要：目的了解重庆市区交通干道苯并(a)芘质量污染状况,分析其对人群健康的危害。方法测定重庆市区主要交通干道空气中苯并(a)芘质量浓度、总悬浮颗粒、PM10、PM2·5和PM1浓度,分析各污染物之间的关系。结果除隧道外,重庆市主要交通干道苯并(a)芘浓度最高为0·5707μg/m3,TSP为1·5167mg/m3,PM10为0·8575mg/m3,均超过国家环境卫生标准。结论表明重庆市区大气中苯并芘[B(a)P]污染已极为严重,有必要对其引起的人群健康效应进行深入研究。Objective To understand benzo(a)pyrene pollution on the main traffic roads and analyze its effect on human health in Chongqing city. Methods The concentration of B(a)P,TSP,PM10,PM2.5 and PM1 in the air of the main traffic roads in Chongqing city were detected. The relationships between different pollutants were analyzed. Results The maximal concentration of benzo(a)pyrene ,TSP, PM10 in the air of the main traffic roads other than tunnel were 0.570 7 μg/m^3,1.516 7 μg/m^3 and 0.857 5 mg/m^3, respectively. They all exceeded the national environmental health standard. Conclusions Benzo(a)pyrene pollution is very serious in the air of Chongqing city.
