Concentration change and chemical speciation sort of Zn and Pb in aerosol

ZHANG Meixiu,LIU Yi,LIU Wanyi,ZHANG Zhenbin,ZHANG Liang,GUAN Feng,LIU Miao(College of Environment and Resources,Jilin University,Changchun 130012,China)  
Atmospheric aerosol was collected with a large flow of aerosol sampler in Changchun Kuancheng District between December 2011 and October 2012 and the content and chemical forms distribution of Zn and Pb was analyzed.The results show that the annual mean concentration of Zn and Pb was 0.438and 0.083μg/m3.The concentration changes obviously with the seasons,both of which showed the highest in winter and lowest in summer.The HAc soluble and reducible of Zn has a large proportion that share more than 84.9%,the sum of the HAc soluble and reducible of Pb is more than 63%.The bioavailability of Zn is higher than that of Pb.The highest bioavailability factor of Zn is in the summer,but Pb shows its highest bioavailability factor in winter.
