    2013年济南市采暖季大气细颗粒物污染监测分析

    Fine Particulate Matters Analysis in Air During Heating Season in Jinan in 2013

      摘要
    • 摘要:
      目的  了解济南市采暖季空气中细颗粒物(PM2.5)含量及成分, 为进行空气污染源解吸提供依据。
      方法  选择2013年冬季空气污染较重日期, 分别在济南市历城区和市中区2个监测点采集PM2.5样品, 分析样品质量浓度及多种无机元素、水溶性离子和多环芳烃的含量, 对大气颗粒物浓度、特征组分、变化趋势进行分析。
      结果  济南市冬季PM2.5平均水平历城区高于市中区, 两监测点PM2.5中含量最高的前四类成分分别是硝酸根离子、硫酸根离子、铵离子、氯离子; 所测空气中12种金属结果显示, 市中区和历城区空气中含量最高的三种金属均为铝、铅、锰; 所测空气PM2.5中16种多环芳烃结果显示, 市中区和历城区空气中含量最高的三种多环芳烃均为苊烯、萘、二氢苊。
      结论  2013年济南市历城区和市中区采暖季空气中细颗粒物含量均超过国家一级标准限值, 济南市空气污染有明显的燃煤特征。

       

      Abstract:
      Objectives  To understand the content of fine particles and their components in the air in Jinan City during heating season, and to provide the basis for stripping the source of air pollutants.
      Methods  Air samples in 2 monitoring points, Licheng District and Shizhong District of Jinan City, were collected in the winter of 2013 when air pollution was heavy. The content of inorganic elements, water soluble ions and polycyclic aromatic hydrocarbons in PM2.5 were analyzed. The concentration, characteristic components and the variation trend of atmospheric particles were also analyzed.
      Results  The level of PM2.5 in winter is higher in Licheng District than that in Shizhong District of Jinan, the four highest ion components in PM2.5 were NO3-, SO42-, NH4+ and Cl-. The content of aluminum, lead and manganese were the highest in all 12 kinds of metals analyzed for air samples. The content of acenaphthylene, acenaphthene and two hydrogen naphthalene were the highest in all 16 kinds of polycyclic aromatic hydrocarbons analyzed for air samples.
      Conclusions  The content of fine particulate matters in the air in Licheng District and Shizhong District of Jinan City during the heating season in 2013 was higher than the national standard limits. The air pollution in Jinan City was mainly caused by burning coal.
