石家庄市冬季大气颗粒物中水溶性离子与重金属成分研究
Study on water soluble ions and heavy metals in atmospheric particulates in winter in Shijiazhuang City
摘要
Abstract
In order to study the composition of atmospheric particulates in Shijiazhuang,PM10 and PM2.5 samples are collected in Shijiazhuang in January,2015.Ion chromatography and ICP-MS are used to determine the contents of 8 kinds of water soluble ions and 6 kinds of heavy metal elements.The results show that the concentrations of Cr,Cu,Zn,Cd,Pb,Ni in PM10 are in the range of 0.02～1.72 μg/m3.The average concentration of water-soluble inorganic ions is 125.5 μg/m3,and C1-,NO3,SO24-and NH4+ are the main components,whose ion mass fraction are 11.6％,7.8％,43.4％ and 19.0％,a total of 81.8％.The concentration range of 6 kinds of heavy metals in PM2.5 is 0.01～ 1.23 μg/m3,and the average concentration of water-soluble inorganic ions is 104.9 μg/m3.Cl-,NO3,SO42-and NH4+ are the main components,whose ion mass fraction are 12.5％,7.2％,43.3％ and 18.7％,a total of 81.7％.NH4+ has good correlation with SO24-in PM10 and PM2.5,and NH4+ may exist mainly as sulfate.The correlation of heavy metals in PM10 and PM2.5 samples is basically the same.The correlation between Cr and Ni is good and may be derived from the same source,and the significant correlation between Cu,Zn and Ni indicates that these three elements are likely to be homologous.关键词
