天津机场区域大气NO2及O3影响因子研究
Study on influencing factors of atmospheric NO2 and O3 in Tianjin Binhai International Airport
在紧邻天津机场跑道的点位对机场区域大气常规污染物开展连续监测,应用广义加性模型(GAM),针对2017年3月1日~2018年2月28日间的NO2及O3,识别其影响因子,并确定因子贡献率.选取因子包括环境因子(SO2、NO、NO2、O3、CO、PM2.5、PM10、前一小时NO2/O3浓度),气象因子(风向、风速、温度、露点温度、修正海压)及航空活动因子(起飞、着陆).结果显示:机场区域NO2日均值为17.6~123.6μg/m3,超标天数共计38d,占比约13%;O3日均值为1.0~276.1μg/m3,超标天数占比26%,污染主要集中在夏季;环境因子是主要影响因子,累积贡献率在56%~89%;航空活动作为区域重要污染源,对大气NO2、O3存在一定影响,最高贡献率可达20%;气象因子相对贡献较低.全部GAM的Adj-R2为0.85~0.96,筛选的影响因子能够有效解释区域环境空气污染物浓度的变化.
Continuous monitoring of atmospheric conventional pollutants in the airport area was carried out at the point adjacent to the runway of Tianjin airport. The Generalized Additive Model (GAM) was applied to identify the impact factors of NO2 and O3 between March 2017 and February 2018, and the contribution rate was determined. The selected factors included environmental factors (SO2, NO, NO2 and O3, CO, PM2.5, PM10 and previous concentration), meteorological factors (wind direction, wind speed, temperature, dew point temperature, correction of sea pressure) and aviation activity factors (takeoff and landing). The results showed that the daily mean of NO2 was 17.6~123.6 μg/m3. Among them, the number of days exceeding the standard was 38, accounting for about 13%. The daily mean of O3 was 1.0~276.1 μg/m3, accounting for 26% of the days exceeding the standard. The pollution of O3 in the airport area was mainly concentrated in summer. Environmental factors, whose contribution ratewas between 56% and 89%, were the main factors affecting the atmospheric environment in the area. As an important regional pollution source, the contribution rate of aviation activities to the change of atmospheric NO2 and O3 concentration was more prominent, Which accounts for 20%. The relative contribution of meteorological factors was relatively low. All Adj-R2 of GAM were from 0.85 to 0.96, and the screened influence factors could effectively explain the variation of conventional gaseous pollutants.
