【摘要】 本文采用X射线荧光法对抚顺地区大气总悬浮微粒（TSP）中S等20种元素的浓度水平进行分析,并通过元素的富集因子分析探讨TSP元素富集特征和污染来源,结果表明:采暖期TSP浓度水平明显超过国家三级标准,其中富集程度较高的S,As,Zn等主要来源于煤炭燃烧。更多还原

【Abstract】 The concentration levells of 20 elements of total suspended particulates (TSP)in air of Fushun have been investigated by the X-ray fiuoresscence analysis method. The enrichment characeteristics and the source of TSP elements are studied from the elemental enrichment,the result inidicate that the concentration of TSP in heating season exceed the 3 lealvel of GB,in which the higher enrichment extent of S,As,Zn in TSP are mainly from the coal-burning dust.更多还原
