摘要
为了确定抚顺市PM10中元素的浓度特征及其来源,于2006—2007年的采暖季、风沙季和非采暖季在抚顺市的6个采样点采集PM10样品,并用等离子体原子发射光谱法(ICP-AES)测定样品中Ti、Al、Mn、Mg、Ca、Na、K、Cu、Zn、As、Pb、Cr、Ni、Co、Cd、Fe、V等17种元素的含量。结果表明,Al、Mg、Ca、Na、K、Mn、Fe等地壳元素在17种元素中占有较大比重,全年平均达到97.0%。富集因子分析结果表明,Cu、Zn、Pb、Cr、Co、Cd等元素在各季和各采样点明显受到人为活动影响,是典型的污染元素。主因子分析结果显示,土壤风沙尘、建筑尘、燃煤尘、道路扬尘、机动车尾气排放、金属冶炼、锰、铜、钛工业源是抚顺市PM10中元素的主要来源。
In order to investigate the elemental concentrations and their source of atmospheric PM10 in Fushun,PM10 samples were collected at six sites in heating season,sand season and non-heating season from 2006 to 2007 in Fushun.And the concentrations of 17 elements in the samples（Ti,Al,Mn,Mg,Ca,Na,K,Cu,Zn,As,Pb,Cr,Ni,Co,Cd,Fe,V） were determined using ICP-AES technique.The results showed that the crustal elements（Al,Mg,Ca,Na,K,Mn,Fe） accounted for a large proportion of all the 17 elements,97.0% annually.Cu,Zn,Pb,Cr,Co,Cd were typical pollution elements and generally from anthropogenic sources in all the seasons and all the sampling sites by the enrichment factor analysis.The main sources for elements in PM10 were soil dust,constructional dust,coal combustion,road dust,vehicle emission,metal melting and industrial process of manganese,copper and titanium by principal component analysis（PCA）.
