摘要:
采用设置在上海市中心城区交通主干道旁空气质量自动监测站2018年1—12月的观测数据,分析黑碳气溶胶(BC)污染特征及其与PM2.5、SO2、NOx、CO、O3、苯、甲苯、乙苯、二甲苯和气象参数的相关性。结果表明,观测期间内,BC小时均值为(3 038±22) ng/m3,ρ(BC)在ρ(PM2.5)中占比为(11.48±0.12)%。日内ρ(BC)变化呈双峰型,各月份之间ρ(BC)变化不大。ρ(BC)与风速呈负相关,与PM2.5、NOx、CO、苯、甲苯、乙苯和二甲苯呈正相关。

Abstract:
The characteristics of black carbon (BC) aerosol pollution and its relationship with the mass concentration of PM2.5、SO2、NOx、CO、O3, benzene, toluene, ethylbenzene, xylene and meteorological parameters were studied by using the observation data of roadside air quality automatic monitoring station located beside the main traffic road in downtown Shanghai from January 2018 to December 2018. The results showed that the mean hourly concentration of BC was (3 038 ±22) ng/m3and the ratio of BC to PM2.5 was (11.48±0.12)%. The change of BC concentration in the day was bimodal, and it did not change much between months. BC concentration was negatively correlated with wind speed and positively correlated with PM2.5, NOx, CO, benzene, toluene, ethylbenzene and xylene.
