大气例行点位常规监测污染物的相关性分析及防控措施研究

根据济南市历下区5个大气例行监测点位2015年上半年PM2.5、PM10、SO2、CO、NO2、O3逐小时浓度的监测数据,通过SPSS软件对各项污染物的相关性进行分析得出:CO与PM2.5、PM10、SO2、NO2强相关性出现次数最多,表明CO排放源是引起颗粒物污染的主要原因之一.对监测点位周边2 km范围内机动车尾气和餐饮燃煤两项污染源进行排放量估算得出:机动车尾气CO、NOx、PM2.5和PM10年排放量分别为388.18吨、111.18吨、4.35吨和4.72吨;餐饮燃煤CO、SO2、NOx年排放量分别为36.0吨、24.0吨和9.6吨.因此,控制CO排放源对改善济南市大气环境质量至关重要.

Study on Correlation Analysis of Pollutants of Routine Monitoring at Atmospheric Routine Points and Prevention and Control Measures

According to monitoring data of hourly concentration of PM2. 5 , PM10 , SO2 , CO, NO2 , O3 in the first half of 2015 in Lixia District, Jinan City. Strong correlation of CO and PM2. 5 , PM10 , SO2 , NO2 appeared the most times according to correlation a-nalysis of the air pollutants by SPSS , show that massive emission of CO was one of the main causes of particulate pollution . The re-sults of estimates of emissions from vehicle emissions and coal burning restaurants around two kilometers of the monitoring points showed that:CO, NO2 , PM2. 5 and PM10 were pollutants from vehicle exhaust emissions were 388. 18 tons,111. 18 tons, 4. 35 tons and 4. 72 tons, respectively . CO, SO2 and NO2 were atmospheric pollutants from coal burning restaurants emissions were 3. 6 tons, 24. 0 tons and 9. 6 tons, respectively and CO emission accounted for the largest both of two categories of pollution sources. There-fore, it was very important to control the emission of CO to improve the quality of atmospheric environment in Jinan.
