| 摘 要： | 基于多环芳烃（PAHs）对人类健康的影响，采集了石龙区境内11个冬-春季节的降尘样品，并应用色谱-质谱技术检测了其中的芳烃化合物，进而分析了其组成、分布特征和可能的来源．结果表明，降尘样品中共检出169种芳烃化合物，其中13种为USEPA优控多环芳烃．降尘中芳烃化合物的质量分数为0．017×10^-3～0．188×10^-3，均值为0．079×10^-3，芳烃质量分数存在明显的地域差异，同时显示出富三环芳烃的特征．综合分析芳烃环数分布、生物标志物及MP／P，MPI1，FL／PY等分子有机地球化学参数，认为在其较小的地域面积上采矿业和加工业密集对大气环境有着直接的影响，煤尘及煤燃烧产物对区域降尘中芳烃的组成影响较大，极小部分地区受到薪柴燃烧影响．

| Abstract: | Dustfall samples from the Shilong coal-mining area,Pingdingshan,Henan,China,were tested containing polycyclic aromatic hydrocarbons(PAHs) by means of GC-MS technology,which damage the health of human.One hundred and sixty-nine PAHs have been identified in the samples, including 13 US EPA PAHs.The concentrations of PAHs are different in different dustfall samples from various site,which change from 0.017 to 0.188 mg/g,and the mean value is 0.079 mg/g.Of all the PAHs with 2~7 rings,PAHs with 3 rings are the most abundant.Considering organic geochemical parameters such as MP/P, MPI1,FL/PY and biomarkers,we conclude that lots of coalmines and coal industry plants,which locate in the small area,could have direct effect on the ambient atmosphere.Coal dust and coal combustion products influence the component of PAHs in the atmosphere.In addition,straw and wood combustion are small sources for PAHs. |
