摘要
首次采用美国国家环保局规定的大气中挥发性有毒有机物的标准分析方法TO-15分析法,研究了广州地区主导风向通道上大气环境中非甲烷烃(NMHC)、苯、甲苯、二甲苯和乙苯的浓度和空间分布,分析了机动车无铅化后尾气排放中VOCs成分的变化,并结合正在开展的广州地区光化学烟雾综合研究,初步探讨了其来源。
It is the first time to use USA EPA TO - 15 Standard Analysis Method to qualitative and quantify the Volatile Organic Compounds in the samples collected from ambient air in Guangzhou Area by Canisters. Having researched on the concentration- space distribution of NMHC, Benzene, Toluene, p- xylene, o- xylene, ethylbenzene, and Styrene, and integrated the results found in the Photochemical Smogs Research in Guangzhou Area, finally discussed the distribution and forming causes of VOCs in the ambient air environment of Guangzhou Area.
