摘要: 利用2013年10月至2014年9月山东省聊城市大气主要污染物监测数据,分析了各种污染物的时空分布特征及其对空气污染的贡献,探讨了聊城市大气污染的成因。结果表明:2013年10月至2014年9月聊城市轻度污染以上的空气质量日数所占比例高达70.0%,大气中SO2、NO2、CO、PM2.5和PM10浓度季节变化规律明显,即冬季各种污染物浓度远高于夏季。日首要污染物以PM2.5和PM10出现日数最多,其次为SO2作为首要污染物在冬季出现偏多,臭氧8 h作为首要污染物在夏季出现相对较多。聊城市5种污染物对空气污染的影响程度从大到小依次为PM2.5> PM10> NO2> CO> SO2,其中PM2.5与PM10分担率大幅高于其他3种污染物,说明聊城市大气污染属于可吸入颗粒物与细颗粒物主导的类型。相关分析发现,PM2.5和PM10具有来自相同或相似污染源的可能性,扬尘与化石燃料使用是PM2.5和PM10污染的主要成因。

Abstract: Based on monitoring data of main pollutants in Liaocheng from October of 2013 to September of 2014, temporal and spatial characteristic of all pollutants and their contribution to air pollution were analyzed.Reasons of air pollution in Liaocheng were discussed.The results show that the number of days with light pollution level or above accounts for 70% of the whole year.Concentrations of sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO) and particulate matter (PM) have a similar seasonal variation, and they are significantly higher in winter than in summer.The number of days with PM2.5 and PM10 as primary pollutants is the greatest in Liaocheng, followed SO2 in winter.8 hours O3 concentration as the primary pollutant often occurs in summer.The order of contribution rate for five pollutants is PM2.5> PM10> NO2> CO> SO2, and the contribution rates of PM2.5 and PM10 are much higher than those of the other pollutants.It suggests that inhalable particulate and fine particles are prevailing in Liaocheng.Correlation analysis shows that PM2.5 and PM10 are possible to have the same or similar pollution sources.The main reasons for PM2.5 and PM10 pollution are attributed to wind lifting dust and use of fossil fuel.
