摘　　要：采用飞行时间质谱法(SPIMS)对汽修集群挥发性有机物(VOCs)进行走航监测,分析了环境空气中的VOCs物质种类和浓度水平,明确重点管控企业及重点控制污染物。结果表明,朝阳区北部汽修集群中,白天来广营地区VOCs总浓度均值最高。夜间望京街道高于来广营地区。走航到汽修集群高值点位共21处。芳香烃和烯烃类VOCs为各汽修集群的主要污染物。喷涂和溶剂使用是汽修集群环境空气中VOCs的主要来源。Using the time of flight mass spectrometry(SPIMS),the navigation monitoring of volatile organic compounds(VOCs)in repair enterprises was performed.The species and the concentration levels of VOCs in the regional ambient air were analyzed.The regional key management companies and the key control pollutants were clarified.The results showed that the highest level of VOCs concentration was obtained in the Laiguangying area during the day and Wangjing Street at night.During the navigation monitoring,twenty-one high-concentration points of VOCs were found.Aromatic hydrocarbon and olefin were the main pollutants of the automobile repair industry.Spraying and solvent use were the main sources of VOCs in the ambient air of the automobile repair industry.
