摘要
通过在夏、冬两季分别进行的三种粒径颗粒物同步连续采样监测试验,确定了成都市大气颗粒物细颗粒物污染严重且有明显二次污染的污染特征。用多重回归分析、富集因子分析及化学成分的因子分析等方法对颗粒物的化学组成及其来源进行了定性分析,结果表明成都市可吸入颗粒物主要来源于化石类燃料及油品燃烧、生物质或餐饮烹饪行业排放、建筑及冶金行业的排放等。
The serious air fine particles pollution and obvious secondary pollutant characteristics in Chengdu were determined, through synchronously continuous sampling and monitoring activities for three types of particles defined by size in summer and winter respectively. Through qualitative analysis such as multiple regression analysis, enrichment factor analysis, and chemical constituent factor analysis for chemical composition and source of pollutants, it was demonstrated that the inhalational particles mainly originated from the combustion of fossil material and oil, biogenic material, cooking industry emission, building industry emission or metallurgic emission, etc .
