CHARACTERISTICS AND SOURCE ANALYSIS OF WATER-SOLUBLE ION POLLUTION IN ATMOSPHERIC DUSTFALL IN WUHAN UNIVERSITIES

  • 摘要: 于2017年11月采集武汉高校大气降尘样品106个,采用离子色谱仪分析样品中9种水溶性离子(F-、Cl-、NO3-、SO42-、Na+、NH4+、K+、Mg2+、Ca2+)的含量,用相关性分析和比值分析法解析其污染特征,用PCA-MLR模型初步探讨其来源及贡献率。结果表明:武汉高校降尘中主要水溶性离子为Ca2+、SO42-、NO3-,平均浓度顺序为Ca2+>SO42->NO3->K+>Na+>Cl->Mg2+>NH4+>F-,且F-、Cl-、NO3-、SO42-、Na+、K+、Mg2+、Ca2+分布存在明显的空间质异性。m(NO3-)/m(SO42-)为0.28,以固定源污染为主;降尘样品总体呈碱性。9种可溶性离子主要以NaCl、KCl、MgCl2、Mg(NO32、MgSO4、Ca(NO32、CaSO4等形式存在,主要来源于土壤/交通混合源、燃烧源、工业源,三者贡献率分别为8%、12%、80%。
