摘要

摘要: 2014年秋季对鞍山市区6个监测点分别进行了PM_2.5样品采集,用电感耦合等离子体质谱仪(ICP-MS)及电感耦合等离子原子发射光谱法(ICP-OES)分析PM_2.5中Na、K、Cd、V、Cr、Mn、Ni、Cu、Zn、Pb、Al、Mg、Ca、Fe、Ba、As等16种元素的浓度,通过地质累积指数、相关分析方法分析了鞍山市秋季PM_2.5中16种元素的污染状况。结果表明:鞍山市秋季PM_2.5中Pb、Cd、C、As 4种元素在各监测点间最大值与最小值之比大于2,差别较大,其中As元素在监测点间最大值与最小值之比达12.19;Na、K、V、Mn、Ni、Cu、Zn、Al、Mg、Ca、Fe、Ba 12种元素最大值与最小值之比小于2,差别较小。地质累积指数结果显示:Cd、Zn、Pb、As元素处于严重污染,其污染主要来源于钢铁冶炼、煤质燃烧和汽车尾气及轮胎磨损。相关性分析结果显示:Cd与Zn、Pb、Cu来自同一污染源。

Abstract: The PM_2.5 samples were collected at 6 monitoring sites in Anshan during autumn in 2014. The concentrations of 16 elements (Na, K, Cd, V, Cr, Mn, Ni, Cu, Zn, Pb, Al, Mg, Ca, Fe, Ba, As) in the samples were determined by ICP-OES and ICP-MS methods. The pollution status of the 16 elements was studied by Geoaccumulation Index and correlation analysis. The results showed that through the comparison of concentrations of elements from PM_2.5 samples at different monitoring sites, the ratios of maximum to minimum values for Pb, Cd, C, As in PM_2.5 were more than 2, the difference was greater, and especially the ration for As was up to 12.19. The ratios of maximum to minimum values for Na, K, V, Mn, Ni, Cu, Zn, Al, Mg, Ca, Fe, Ba were less than 2, exhibiting smaller difference. The results of Geoaccumulation Index indicated that the elements of Cd, Zn, Pb, As, mainly from iron and steel smelting, vehicles and tire-wear, were extremely contaminated. The relevance results showed that Cd,Zn,Pb,Cu might be from the same types of sources.
