  • 摘要: 为了掌握雾霾期大气PM2.5和PM10中无机元素污染特征,于2013年10月20~31日期间采集了东北某市发生严重雾霾时大气PM2.5和PM10样品,分析了颗粒物样品中21种无机元素(K、Ca、Na、Mg、Mn、Pb、Cd等)的浓度。结果表明:大气PM2.5和PM10浓度普遍超标,超标率分别达88.89%、66.67%;大气PM2.5和PM10中元素质量浓度主要是由Na、S、Ca、K、Fe、Al、Si、As、Mg 9种元素贡献;元素的富集状况分析表明,Na、Zn、Ca、Cr、Ni、Cu、Mn、Cd、Pb和As在非雾霾期和雾霾期期富集程度较高,污染较严重,受人为污染源影响较大;以不同元素做参比,所得各元素富集系数不同。
    Abstract: To investigate the pollution characteristics of inorganic elements contained in PM2.5 and PM10 when severe haze occurred, PM2.5 and PM10 samples were collected in a city located in Northeast China under severe haze days during October 20 to 31, 2013. Concentration of 21 elements contained in the PM2.5 and PM10 samples was analyzed including K, Ca, Na, Mg, Mn, Pb, Cd, etc.. The results showed that the concentration of PM2.5 and PM10 generally exceeded the standards, with exceeding rate of 88.89% and 66.67% respectively. Na, S, Ca, K, Fe, Al, Si, As and Mg were the main elements contained in PM2.5 and PM10. Analysis of the enrichment factors of the elements indicated that the enrichment of Na, Zn, Ca, Cr, Ni, Cu, Mn, Cd, Pb and As were comparatively higher during haze and non-haze periods, causing more serious pollution with anthropogenic pollution source as the main influencing factor. In addition, different elements were compared and the enrichment coefficients of each element obtained were different.
