抚顺地区大气总悬浮微粒的元素富集特征及污染来源研究

Invistigation of The Enrichment Character of Element and The Source of TSP Element in Air

本文采用x射线荧光法分析了抚顺地区采暖期与非采暖期大气总悬浮微粒（TSP）中As等20种元素的浓度水平，用富集因子法、因子分析法及多元回归法识别该地区主要污染源，并估算它们对总悬浮微粒的贡献，其贡献率为：煤炭燃烧26．9％；冶金工业26．8％；风砂土壤22．0％；汽车燃油6．7％；其它污染源17．6％。

this invistigation analyze levles of the concentration of 20 element of TSP in air of FuShun by X - Rainfluores cenco analysis method the distinguishing and contrubution of source of TSP in air,were done by the enrichment Factor method, Factor analysismethod and the pluralistic regression. the rate of contrubution of source is about 29. 69% for coal burning, 26. 8% for metal industry,22.0% for soil,6.7% for other pllution sources.
