  • 摘要: 为了揭示桂林市大气中PM2.5组分特征，本研究于2015年秋季在桂林5个环境受体点采集了PM2.5样品，分析了PM2.5质量浓度及多种无机元素、水溶性离子和有机碳（OC）、元素碳（EC）的含量，并运用富集因子法、比值法等分别研究了PM2.5中元素富集程度、颗粒物来源等情况，并探讨了PM2.5中高硫酸盐（SO42-）的污染成因.结果表明，采样期间，桂林市PM2.5的浓度为（57.0±35.8） μg·m-3，PM2.5中以水溶性离子（56.7%）和有机物OM（22.6%）污染最为突出，其次是元素（7.2%）和EC（6.3%）.PM2.5中Se、Pb、As、Zn、V、Cu严重富集，表明燃煤源排放对桂林市大气中元素产生了较大的影响；[NO3-]/[SO42-]比值小于1，也进一步证明了固定燃烧源的主导作用.SO42-/PM2.5的比值为41%，高于国内其他城市报道值；而SOR均值0.51远高于一次排放源特征值（0.1），表明除本地和区域传输的一次SO42-排放外，SO42-主要来自SO2的二次转化.因此，桂林市在控制本地燃煤源排放的同时，还应当注意区域污染传输对PM2.5的影响.
    Abstract: To investigate the composition of PM2.5, samples were collected at 5 sites from September 2015 to November 2015 in Guilin. Concentrations of PM2.5, inorganic elements, water-soluble ions, organic carbon (OC) and elemental carbon (EC) were analyzed. Enrichment factor method and ratioing were used to evaluate the element enrichment degree and the source of PM2.5, as well as to investigate the reason for the pollution of high-concentration secondary sulfate in PM2.5. The results showed that the concentration of PM2.5 was (57.0±35.8) μg · m-3, among which the concentrations of water-soluble ions and OM, which contributed the most to the spotted pollution, were 56.7% and 22.6%, respectively, followed by trace element (7.2%) and EC (6.3%). Se, Pb, As, Zn, V and Cu were mainly enriched by anthropogenic pollution, such as coal-burning activities. The ratio of[NO3-]/[SO42-] was less than 1, indicating the dominant role of fixed combustion source. The ratio of[SO42-]/PM2.5 was 41%, higher than reported values in other cities in China, and the average value of SOR was well above the flag value of first emission (0.1). This means that in addition to emission of SO42- from local coal-fired source and regional transmission, most sulfate was from secondary transformation process. Therefore, the effects of regional pollution transmission on PM2.5 should be noted at the same time as emissions from the local coal sources were concerned in Guilin.
