摘　　要：采用自主研发的单光子电离飞行时间质谱仪对珠三角某塑料生产企业生产区域的挥发性有机物(volatile organic compounds,VOCs)进行现场在线监测,初步获取了该企业各生产车间以及污水处理站等地点的VOCs排放源谱,结果显示该企业所有车间均未发现VOCs浓度超标情况。另外还通过对企业内部道路的污染情况与各车间的源谱进行了对比分析,定量评价了各个污染源对道路VOCs的贡献率。这套在线挥发性有机物质谱仪在化工园区VOCs实时在线监测、应急检测、污染模式识别、偷排漏排监控等方面具有广阔的市场。A single photon ionization time-of-flight mass spectrometry（SPI-TOFMS） was applied to the online monitoring of the volatile organic compounds （VOCs） emitted from a plastic company in Pearl River Delta. The source profiles of workshops and sewage treatment station were attained successfully. Over-standard concentration of VOCs has not been found during the monitoring. In addition, the contribution of every pollution source to the internal roads was also evaluated by comparing the source profiles of workshops. This online VOCs mass spectrometry has wide markets in aspects of online VOCs monitoring, emergency detecting, pollution mode recognition and underlying discharge monitoring.
