鞍山市大气中多环芳烃健康影响评价

通过对鞍山市典型区域（6个污染源、4个居住区、一个对照点）大气颗粒物中PAHs的监测，采用BaP当量致毒系数TEF，研究了鞍山市大气颗粒物中典型PAHs毒性当量分布特征。研究结果表明，鞍山大气中典型PAHs污染主要以4～6环为主，不致癌BaP当量浓度为0．066ng/m3，致癌BaP当量浓度为12．7ng／m3，强致癌BaP当量浓度为8．1ng/m3，很强致癌BaP当量浓度为12．7ng／m3。BaP毒性当量浓度呈现出采暖期要远远高于非采暖期，工业区及工业区周边BaP毒性当量浓度要远远高于居住区和对照点。

Health Impact Assessment of PAHs on Atmosphere of Anshan

The polycyclic aromatic hydrocarbons（PAHs） in large atmospheric particles were monitored in the typical areas of Anshan （6 pollution sources,4 residential areas and a control point） with BaP as toxicity equivalent factor （TEF）. Distributions of PAHs toxic equivalent of atmospheric particle was also investigated in Anshan. The results show that the 4 to 6 rings are the main PAHs pollution areas in Anshan. No carcinogenic BaP equivalent concentration is 0. 066 ng/m3. BaP concentration equivalent to cancer is 12. 7 ng/m3. Strong carcinogenic BaP equivalent concentration is 8. 1 ng/m3. The stronger carcinogenic BaP equivalent concentration is 12. 7 ng/m3. BaP toxicity equivalency quantity was much higher in heating period than in non - heating period. BaP toxicity equivalency quantity in industrial zone and surrounding areas was also much higher than in residential areas and control point.
