摘要
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、SO_2、CO、NO_2、O_3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、SO_2、NO_2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、NO_x、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、SO_2、NO_x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。
According to monitoring data of hourly concentration of PM2.5, PM10, SO2, CO, NO2, 03 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 analysis of the air pollutants by SPSS , show that massive emission of CO was one of the main causes of particulate pollution. The resuits 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.
