Abstract对比研究了隧道和大气环境中不同粒径细颗粒物(切割粒径分别为0.03,0.06,0.108,0.17,0.26,0.40,0.65,1.0,1.6和2.5μm)中S,K,Ca,Ti,Mn,Fe,Zn,Pb,Al,Si,Cu和V等12种痕量元素的浓度.结果表明:隧道中不同粒径细颗粒物的数浓度和质量浓度在上下班高峰时段出现明显峰值,且隧道细颗粒物在0.108μm粒径处的数浓度和在2.5μm粒径处的质量浓度分别是大气环境对照值的15.2和40.0倍;在隧道传输过程中质量浓度增加的痕量元素有Si,Ca,Fe,Al,Ti,Zn,Mn,Cu和V,减小的有S,Pb,Zn和K;地壳元素(Si,Ca,Fe,Al和Ti)的质量浓度总和占隧道细颗粒物中痕量元素质量浓度总和的87%,表明土壤扬尘仍是隧道大气细颗粒物的主要来源.
