基于吉林市空气自动监测站数据,对影响吉林市雾霾天气的气象条件,汽车尾气,城市生产生活废气,烟花爆竹等生产生活行为进行逐一分析,确定吉林市雾霾产生是上述四种原因所致。对雾霾的主要成分PM_(2.5)进行化学源解析,确定有机碳(OC)是吉林市PM_(2.5)中质量浓度最高的化学组分,其次是NO_3~-和SO_4~(2-),煤烟尘和机动车尾气是吉林市雾霾的主要贡献者。
Based on the data of Jilin City Automatic Air Monitoring Station, the author analyzed the production and living behaviors of haze and fog in Jilin City one by one based on the meteorological conditions, automobile exhaust, urban production and living exhaust, fireworks and firecrackers, and so on to determine the causes of smog in Jilin City To The chemical composition of PM_ (2.5), the main component of smog, was analyzed by chemical analysis. The results showed that organic carbon (OC) was the highest concentration of PM_ (2.5) in Jilin City, followed by NO_3 ~ - and SO_4 ~ Coal dust and motor vehicle exhaust are the major contributors to smog in Jilin City.
