| 摘 要： | 基于《南京市环境空气中可吸入颗粒物（PM10）源解析及控制对策研究》课题研究成果,课题于2004年-2005年间共采集了197个源和受体样品,每个样品分析测试了三类化学元素,采用化学质量平衡（CMB）模型解析南京市环境空气中可吸入颗粒物的来源,其中48%来源于扬尘、土壤尘等开放源类。研究认为扬尘等开放源类是南京市可吸入颗粒物污染的首要因素。

| Abstract: | 197 PM10 samples for receptor and sources were collected at six urban air quality monitoring sites and different pollutant sources in Nanjing during November,2004 and June,2005.Three kinds of chemical elements were analyzed by different analyzers.The quantitative analysis on source apportionment of PM10 was made by applying chemical mass balance model（CMB） technique.Some general rules on air particulate souce and its seasonal distribution characteristics were concluded through identifying different type of sources and the characteristics of their compositions,analyzing and comparing the concentration levels of those in receptors,together with calculating pollution contributive rate of different type of sources to Nanjing in different seasons.The paper indicated the main sources of urban PM10 are urban fugitive dust,vechical exaution dust and coal soot,which should be taken a major fators of PM10 pollution control. |
