摘　　要：通过罐采样-GC-MS/FID采集及分析系统,测定了北京市工业区内典型溶剂使用企业挥发性有机物（VOCs）的排放成分.结果表明：在汽车喷涂企业中,芳香烃（22%~55%）和烷烃（13%~44%）是重要的VOCs排放组分,印刷企业排放的主要组分为烷烃（43%~71%）和含氧VOCs（17%~19%）,电子光刻企业排放的特征组分是丙酮（10%~18%）,但不同电子光刻企业VOCs其它组分比例相差较大;企业中采用的VOCs处理装置对VOCs排放组成有重要影响;与已有研究的源谱比较,印刷行业源谱较相似,主要以烷烃为主,也有部分芳香烃.汽车喷涂行业的源谱有很大变化,可能是由于汽车涂料成分改变而造成.VOC emission compositions from solvent use factories in Beijing were measured using canister-GC-MS/FID analysis system. Aromatics（22%~55%） and alkanes（13%~44%） were major species in auto-painting factories while alkanes（43%~71%） and oxygenated VOCs（17%~19%） were dominant in printing factories. VOC species emitted from electronic lithography industries were characterized as high content of acetone（10%~18%）,while the proportion of other VOC components were quite discrepancy as to different manufacturers. VOCs treatment facilities,such as the catalytic combustion system,could re-shape the VOC profiles from the factories. Comparing with previous studies,our results showed that the printing profiles were similar,in which alkanes and aromatics were the most abundant species,while the profiles of auto-painting were very different from the others,very likely due to changes in the paints.
