摘要
为了进一步了解蒙阴县环境空气质量状况及污染现状,利用2019年蒙阴县主城区空气质量数据,结合空气质量指数(AQI)分析。探讨蒙阴城区空气质量状况、首要污染物分布及首要污染物变化趋势,旨在为蒙阴县大气污染防治提供一定理论依据。结果表明:①2019年全年有效监测天数363天,其中优良天数200天,占比约55%,轻度以上污染163天,占比约45%。空气质量污染指数最大值为346,最小值17,基本呈现冬季高,春秋次之,夏季低的趋势。②影响空气质量的六项空气污染物中,SO2、NO2、CO全年浓度较低且不超标,而O3、PM2.5、PM10均有超标,且是影响AQI的主要因素,O3为首要污染物142d,PM2.5为首要污染物122d,PM10为首要污染物75d。③PM2.5、PM10、O3污染具有季节效应,冬季污染主要是PM2.5、PM10,夏季主要为O3。
In order to further understand the environmental air quality status and pollution status of Mengyin County, the air quality data of the main urban area of Mengyin County in 2019 was used in conjunction with the Air Quality Index(AQI) analysis. To explore the air quality status, the distribution of primary pollutants and the trends of primary pollutants in Mengyin City, aiming to provide a theoretical basis for the prevention and control of air pollution in Mengyin County. The results show that: ①The number of effective monitoring days for the whole year of 2019 is 363 days, of which 200 are excellent days, accounting for about 55%, and 163 days are light pollution or above, accounting for about 45%. The maximum value of the Air Quality Pollution Index is 346 and the minimum value is 17, which is basically high in winter, followed by spring and autumn, and low in summer. ②Of the six air pollutants that affect air quality, the concentration of SO2, NO2, and CO is low and does not exceed the standard throughout the year, while O3, PM2.5, and PM10 all exceed the standard, and are the main factors affecting AQI. O3 is the first Pollutant 142 d, PM2.5 is the primary pollutant 122 d, PM10 is the primary pollutant 75 d. ③PM2.5, PM10, O3 pollution has a seasonal effect, winter pollution is mainly PM2.5, PM10, summer is mainly O3.
