摘要
依据2013年白龙岗站点自动监测数据,对PM2.5污染特征及手工采集的PM2.5膜中水溶性阴离子进行分析,并结合实际提出相应的防治对策。结果表明,PM2.5作为首要污染物,其分布具有季节性特征,冬季最高,夏季最低;灰霾日PM2.5、PM10、SO2和NO2具有相同的变化趋势;NO-3/SO2-4的比值表明宜昌市呈现工业污染和机动车尾气污染的复合污染特征。
Based on the data from air quality automation monitoring system in Bailonggang monitoring station, pollution characteristics and water soluble ions in PM2.5 by manual sampling were analyzed. The prevention countermeasures were put forward based on reality. Results showed that PM2.5 were the primary pollutants, the seasonal factors have been found when PM2.5 in winter was much higher than in summer; PM2.5, PMlo, SO2 and NO2 has the on same variation trend. NO3^-/SO4^2- indicated complex pollution was mainly caused by industrial pollution and vehicle exhaust in Yichang City.
