摘要

为探究黄冈市臭氧(O3)污染情况,论文对2018—2019年黄冈市国控站点的监测数据进行统计分析,并对同期生成臭氧的关键前体物——挥发性有机物(VOCs)的在线监测结果进行分析研究,结果表明:O3浓度变化呈现明显的季节差异,夏季污染最严重,其次为春季和秋季;O3高浓度时段为5～10月,低浓度时段为11～12月和1～4月。对O3生成潜势最关键物种为乙烯、间/对-二甲苯,甲苯、丙烯、邻二甲苯、丙醛、2-丁酮、反-2-丁烯;燃烧源(29.9%)、工业源(28.7%)和汽油车排放(28.0%)为VOCs浓度贡献率最大的3类源。
        In order to study the ozone(O3) pollution characteristics in Huanggang, this paper analyzed the O3 data monitoring by the Huanggang National Control Station from 2018 to 2019. And the one-year online volatile organic compounds(VOCs) in the same period were analyzed. The results showed that O3 concentrations in Huanggang had obvious seasonal characteristics. The worst O3 pollution appeared in summer, followed by spring and autumn. The whole year can be divided into O3 high concentration period(May to October) and O3 low concentration period(November to December and January to April). Ethylene, m/p-xylene, toluene, propylene, o-xylene,propionaldehyde, 2-butanone, and trans-2-butene were the most important VOCs species to ozone formation potential(OFP) in Huanggang.The sources of combustion(29.9%), industrial source(28.7%) and gasoline vehicle emissions(28.0%) were top three contributor to ambient VOCs in Huanggang.
