| 摘 要： | 研究采集了黑龙江松嫩平原南部28个夏季大气颗粒物样品，分析了不同粒径(TSP、PM10、PM2-5)样品中常量和微量元素含量，对元素浓度含量特征、元素间相关性和空间分布特征进行了分析，并使用富集系数法和因子分析法进行元素来源解析。研究表明：在PM10-100中富集的元素多在地壳中含量很高，重金属元素在PM2-5中高度富集，不同粒径大气颗粒物中各元素质量浓度整体水平为：大庆>绥化>哈尔滨>齐齐哈尔。富集因子分析表明：Fe、K、Ti、Mn、Co的富集因子小于1或非常接近1，Ca、Mg、Ni、Cr的富集因子大于1但仍小于10，Na、Zn、Cu、Cd、Pb、Se的富集因子大于10，表现出较为明显的人为来源特征。参照颗粒物不同源主要标识元素，对各元素进行主因子分析结果表明：松嫩平原南部大气可吸入颗粒物的主要来源是土壤扬尘，此外还有燃煤、垃圾焚烧、汽车尾气、碱尘大气传输、燃油和工业来源。

| Abstract: | Twenty-eight samples of atmospheric particles were collected from the southern area of Song-Nen plain,during the summer of 2008.Both the major and minor element concentrations in the samples were analyzed in this research.This paper shows the mass concentrations,correlations and spatial distributions of the elements.And also,the sources of the various elements were identified by enrichment factors and factor analysis.The results show that the elements which are abundant in PM10-100 particles are those which have high concentrations in the crust.Heavy metals have relatively high concentrations in the PM2.5 particles.Mass concentrations of atmospheric particles decrease as: Daqing > Suihua > Harbin > Qiqihar.The enrichment factors of Fe,K,Ti,Mn and Co are smaller than 1 or very close to 1.As for Ca,Mg,Ni and Cr,the enrichment factors are greater than 1 but still smaller than 10.Whereas the enrichment factors of Na,Zn,Cu,Cd,Pb and Se are greater than 10,indicating these elements have anthropogenic sources.The varimax rotated factor analysis shows that the major source of atmospheric inhalable particles is soil dust.Other sources include coal combustion,garbage incineration,automobile tail gas,alkali dust through atmospheric transmission,fuel combustion and industrial sources. |
