摘　　要：利用禾信质谱监测车,以昆明和蒙自为研究对象,对其空气中VOCs进行测定,监测结果显示:昆明市与蒙自市环境空气中VOCs浓度均处于正常水平,主要物质成分基本相同,主要以苯系物、烷烃和烯烃类物质为主,主要来自自然排放以及人类城市生活活动排放;企业区域监测,VOCs浓度具有明显的区域性特征,蒙自市VOCs浓度相对昆明市较低,昆明市和蒙自市分别含有恶臭污染物二甲基二硫醚、乙硫醚,二甲基二硫醚、乙硫醇。The VOCs in the air were determined in both Kunming city and Mengzi city using Hexin SPIMS monito-ring vehicle.According to the monitoring results,the VOCs concentration in the ambient air of Kunming city and Mengzi city is at a normal level.The main components are basically the same,namely benzene series,alkane and olefin,mainly from natural emissions and human urban living activities emissions.According to the regional monitoring of enterprises,VOCs concentration has obvious regional characteristics.Compared with Kunming city,VOCs concentration in Mengz city is lower.Kunming city and Mengzi city respectively contain dimethyl disulfide,ethyl thioether,dimethyl disulfide and ethyl mercaptan,which are odorous pollutants.
