  • 摘要: 2015年1月份采集鞍山市主城区共6个采样点的PM2.5样品，并采集了固定源、移动源、开放源、生物质燃烧源、餐饮油烟等5类污染源，使用GC-MS进行16种多环芳烃（PAHs）质量浓度的分析，运用PMF法和毒性当量分别进行了来源解析和毒性评价.结果表明，鞍山市主城区冬季大气PM2.5中ρ（PAHs）和ρ（BaP）较高，PAHs以3环、4环为主，占PAHs总浓度的82.56%；冬季大气中PAHs主要来源为煤烟尘、焦化尘、移动源、开放源、生物质燃烧源和其他污染源，其贡献率分别为27.8%、24.2%、18.1%、13.4%、4.7%和11.8%；毒性评价表明，鞍山市冬季PAHs的TEQ均值为33.51 ng·m-3，铁西三道街的毒性当量浓度最高.
    Abstract: PM2.5 samples were collected in January 2015 from six main sampling sites in Anshan city. Stationary source,mobile source,open source,biomass burning sources and cooking oil fume were sampled. The concentrations of PAHs were analyzed by GC-MS, and the sources of PAHs were analyzed by PMF and the toxicity assessment was conducted by TEQ. The results showed that the ρ (PAHs) and ρ (BaP) contents in PM2.5 were high,and the three and four ring PAHs were the main PAHs in the city, accounting for 82.56%. The main sources of PAHs in the atmosphere were coal dust, coke dust, mobile source, open source, biomass burning sources and others sources of pollution,the contributions were 27.8%,24.2%,18.1%,13.4%,4.7% and 11.8%,respectively. The toxicity assessment showed that the mean TEQ of PAHs in Anshan was 33.51 ng·m-3,and the TEQ was the highest in TXSDJ.
