该研究利用在线监测仪器获取了咸宁市2021年6-8月环境大气中107种挥发性有机化合物(VOCs)小时浓度数据,对比研究了咸宁市臭氧污染日与非污染日VOCs组成及来源。观测期间,VOCs臭氧污染日平均浓度为16.6×10~(-9),非污染日平均浓度为13.9×10~(-9)。臭氧污染日各类VOCs浓度占比大小为烷烃(31.3%)丙酮(25.6%)卤代烃(13.6%)OVOCs(8.8%)烯烃(7.6%)乙炔(6.9%)芳香烃(6.2%)。利用最大反应增量估算了各类VOCs对臭氧生成潜势贡献大小,具体为烯烃(49.4%)芳香烃(16.2%)OVOCs(13.9%)烷烃(11.6%)乙炔(4.3%)。将监测数据输入PMF模型,结果显示,污染日VOCs最主要来源为机动车排放源及工业排放源,非污染日VOCs最主要排放源为机动车排放源。
