摘要
采用气相色谱/质谱检测技术,对汽油和柴油、汽油车和柴油车排放气体以及天津市环境空气中主要挥发性有机污染物(VOCs)的组成种类及比例进行探析。结果表明,机动车排放的尾气中主要有机污染物为芳香烃类、烷烃类和烯烃类化合物,其中芳香烃类含量最高;汽油车排放的芳香烃类化合物浓度高于柴油车排放的浓度;机动车尾气对交通区域空气质量的影响高于工厂区(非化工区)、生活小区和公园。
The main volatile organic compounds in Tianjin ambient air, gasoline and diesel, and vehicle exhaust were qualitatively and quantitatively studied with GC/MS. The ingredients and their concentration had been compared respectively. Aromatic hydrocarbons, alkane, alkene were the main compounds in fuels and also in exhausted pollutants from vehicles. Aromatic hydrocarbons were more serious than other pollutants, and their concentrations were higher for gasoline vehicles than for diesel vehicles. The pollutions concentrations in traffic area were higher than them in factory area, living community, and garden.
