| 摘 要： | 为了解广州市气溶胶中有机示踪化合物的分布特征,采用N,O-双（三甲基硅烷基）三氟乙酰胺（BSTFA）衍生化预处理技术和GC/MS分析技术,于2002—2003年对广州市大气气溶胶中的有机示踪化合物进行了定性和定量分析.结果表明,脱水糖类、β-谷甾醇、脱氢松香酸主要来源于生物质燃烧;葡萄糖、果糖、蔗糖、海藻糖等主要来源于土壤的再悬浮;藿烷类、甾烷类化合物主要来源于化石燃料的燃烧;胆甾醇可以作为肉类烹饪等餐饮源的有机示踪物.广州市大气中所检测到的所有糖类化合物与植物蜡的浓度比值春、秋两季较高,这可能与春天是植物叶片扩张和耕耘播种的季节、秋天是果实成熟和农作物收割的季节有关.

| Abstract: | To investigate the distribution of organic molecular tracers in the aerosol of Guangzhou,organic molecular tracers of the total suspended particles(TSP),collected in Guangzhou from 2002 to 2003,were derivatized with N,O-bis-(trimethylsilyl)trifluoroacetamide(BSTFA) and then analyzed by gas chromatography-mass spectrometry(GC/MS).The results show that the anhydrosaccharides,β-sitoscrol and dehydroabietic came from biomass burning.Glucose,sucrose,fructose and mycose were the result of resuspension of surface soil dust.Hopanes and steranes came from fossil fuel combustion.Cholesterol was from cooking emission.Concentration ratios of the saccharides to the total plant waxes occurred high level in spring and autumn,probably associating with plant growing and leaf expanding in spring,maturity season of fruits in autumn,and the agricultural activities and biomass burning in autumn. |
