摘要
分别选取华南和华北某橡胶制品企业炼胶废气进行了挥发性有机物(VOCs)采样分析。结果表明,华南某橡胶企业排放VOCs中芳香烃(58.22%)和含氧VOCs(30.46%)比例较高,主要化合物是苯乙烯和甲基异丁基酮;而华北某橡胶企业排放VOCs主要是烷烃(37.60%)和芳香烃(27.78%),主要化合物包括甲基环戊烷、间/对-二甲苯和正己烷等。芳香烃对臭氧生成潜势(OFP)和二次有机气溶胶生成潜势(SOAFP)贡献最大,分别贡献了OFP的58.92%和59.47%,SOAFP的93.59%和88.12%。
Volatile organic compounds(VOCs)samples were collected and analyzed for two rubber products industries in South China and North China.VOCs emitted from the rubber products industry in South China were mainly aromatics(58.22%)and oxygenated VOCs(30.46%),and the typical species included styrene and methyl isobutyl ketone as the most abundant species.While for the rubber products industry in North China,alkanes(37.60%)and aromatics(27.78%)were the main VOC group with methyl cyclopentane,m,p-xylenes and n-hexane as the most abundant species.Aromatics were the most important contributor to ozone formation potential(OFP)and secondary organic aerosol formation potential(SOAFP),which contributed 58.92%and 59.47%of OFP,and 93.59%and 88.12%of SOAFP,respectively.
