摘要
采用山东大学蓝翔技校、泉城广场、建筑大学和跑马岭4个点位SO2、NO2、PM10、PM2.5、PM1和O3等的监测数据,研究了山东大学灰霾期大气污染物的污染特征。结果表明:灰霾天气下,各类大气污染物浓度均有不同程度的增加,且PM2.5、PM1较其它大气污染物浓度增幅较大,山东大学PM2.5占PM10的60.3%,PM1占PM2.5的65.7%,说明山东大学大气细粒子对灰霾的贡献率最大。典型灰霾天气下,大气颗粒物污染呈现出"南部山区好于城区、城区好于城乡接合部"的分布特征。市区VOCs与PM10、PM2.5、SO2、NO2均呈显著正相关,而O3与SO2、NO2呈显著负相关,这与光化学反应有关。
SO2,NO2,PM10,PM2.5,PM1,O3 and so on are monitored in haze monitoring sites in Jinan City including Lanxiang Technical School,Quancheng Square,Jianzhu University and Paomaling.Pollution characteristics of air particles during haze period are studied.The results show：During dust haze,the air pollutant concentration increases by different degree and PM2.5 and PM1 increase substantially.The contribution concentration of PM2.5 to PM10 is 60.3% and PM1 to PM2.5 is 65.7%,which shows the largest contribution of fine particles to haze.During typical haze condition,the distribution characteristics of fine particles pollution is that southern mountain area is better than the city and the city is better than fringe area.The VOCs concentration in city has significantly positive correlation with PM10,PM2.5,SO2 and NO2,but ozone has significantly negative correlation with SO2 and NO2,which is related to photochemical reaction.
