    摘要
  • 摘要: 于2017年10月15—11月14日在聊城市区采集PM2.5样品,并对其中的水溶性离子(Na+、 NH 4 + 、K+、Mg2+、Ca2+、F-、Cl-、 NO 3 - 、 SO 4 2 - )进行分析测试,以研究聊城市秋季PM2.5污染特征。结果显示:观测期间PM2.5浓度均值为(104.9±50.5)μg/m3,超过GB 3095—2012《环境空气质量标准》二级标准浓度限值0.40倍;水溶性离子浓度为(52.2±35.1)μg/m3,占PM2.5的45.7%±11.3%,其中 NO 3 - 、 SO 4 2 - 和 NH 4 + 为主要组分,占水溶性离子和PM2.5的比例分别为85.2%和45.0%;随PM2.5污染加重,水溶性离子浓度升高, NH 4 + 占比亦逐渐升高, NO 3 - 及 SO 4 2 - 占比先升高后有所下降,其他离子占比尤其是Ca2+随之下降,表明PM2.5浓度的升高主要受二次无机转化影响;硫转化率(SOR)与氮转化率(NOR)均值分别为0.28和0.27,表明聊城市秋季SO2与NO2转化速率较高,二次无机污染较为严重,另外SOR及NOR与温度及相对湿度呈显著正相关,且SOR对相对湿度更加敏感而NOR对温度更为敏感;聊城市秋季PM2.5呈弱碱性, NH 4 + 的存在形式主要是(NH4)2SO4和NH4NO3。主成分分析结果表明,二次无机转化、扬尘源和工业生产排放是聊城市秋季PM2.5中水溶性离子的主要来源。

     

    Abstract: PM2.5 samples were collected during autumn in Liaocheng City from October 15th to November 14th, 2017, and the water-soluble ions (Na+, NH 4 + , K+, Mg2+, Ca2+, F-, Cl-, NO 3 - and SO 4 2 - ) were analyzed to study the pollution characteristics of PM2.5 in autumn in Liaocheng City. The results showed that PM2.5 mean concentration was (104.9±50.5) μg/m3 during the observation period, 0.40 times higher than the daily average concentration limit of Grade Ⅱ standard of Ambient Air Quality Standards (GB 3095-2012). The average concentration of water-soluble ions was (52.2±35.1) μg/m3, which accounted for 45.7%±11.3% of PM2.5. SO 4 2 - , NO 3 - and NH 4 + were the main ions, accounting for 85.2% of the water-soluble ions and 45.0% of PM2.5. As the air pollution got serious, the concentrations of water-soluble ions increased. In addition, the proportion of NH 4 + increased gradually, that of SO 4 2 - , No 3 - increased first but then decreased, while that of other ions especially Ca2+decreased, which indicated that the increase of PM2.5 concentration was mainly affected by the secondary inorganic transformation. The average sulfur oxidation rate (SOR) and nitrogen oxidation rate (NOR) during the observation period were 0.28 and 0.27, respectively, which showed that the secondary transformation of SO2 and NO2 was higher in autumn and the secondary pollution was much serious. In addition, SOR and NOR were positively correlated with temperature and relative humidity, and SOR was more sensitive to relative humidity, but NOR to temperature. PM2.5 in Liaocheng City presented weak alkaline in autumn, and NH 4 + were primarily in NH4NO3 and (NH4)2SO4 forms. The results of the principal component analysis revealed that secondary inorganic transformation, dust sources and industry emissions were the main sources of water-soluble ions of PM2.5 during autumn in Liaocheng City.
