| 摘 要： | 2007年2月在攀枝花市不同功能区采集了大气PM10样品42个和污染源样品32个,采用超声抽提GC/MS方法测定分析了16种多环芳烃(PAHs)的含量。结果显示攀枝花市PM10颗粒相PAHs单体浓度范围为0.34～416.45ng/m3,总量浓度范围为24.56～2569.66ng/m3;攀枝花市5个采样点中河门口片区PM10多环芳烃单体浓度范围为5.64～416.45ng/m3,污染最严重。源样品测定结果分别为扬尘78.74ug/g,煤烟尘6.12ug/g,钢铁工业尘30.54ug/g,焦化尘3187.42ug/g。应用比值法和化学质量平衡(CMB)模型对污染源进行识别,燃煤和炼焦是攀枝花市PAHs的主要来源,对攀枝花市大气可吸入颗粒物中多环芳烃污染的分担率分别为55.8%、19.9%。

| Abstract: | Total 42 atmospheric samples of PM10 and 32 pollutant source samples were collected in Panzhihua City during February 2007.The concentrations of 16 Polycyclic Aromatic Hydrocarbons were analyzed using GC/MS.The concentrations of monomers and total particulate phase PAHs ranged from 0.34～416.45 ng/m3,24.56～2 569.66 ng/m3,respectively.Hemenkou had the highest monomers PAHs concentration in five functional areas in Panzhihua,which ranged from 5.64 to 416.45 ng/m3.The PAHs content of resuspended dust,coal combu... |
