【摘要】 采集南京市燃煤、焦化、机动车和烹调四种污染源样品,采用高效液相色谱仪测定其中的PAHs含量,建立四种源的成分谱.根据所得数据,运用化学质量平衡(CMB)受体模型对PM10中的PAHs进行源解析研究,以确定燃煤源、焦化源、交通源和烹调源对PM10中PAHs的贡献率.更多还原

【Abstract】 The samples of four sources were collected,such as coal combustion,coke plant,motor vehicle and dining hall.Both source and receptor samples were pretreated. High performance liquid chromatography (HPLC) was used to analyze the sixteen PAHs in pretreated samples.Based on the determined data at various sampling sites,the main sources of PAHs on inhalable particles in Nanjing city were estimated by chemical mass balance (CMB) receptor model,the contribution rate of different PAHs sources were obtained.更多还原
