Seasonal Variation of Water-Soluble Organic Compounds in Aerosols of Guangzhou, China

  • 摘要: 采用BSTFA 衍生化预处理和GC/MS 分析技术, 于2002─2003年对广州市荔湾区大气气溶胶中的水溶性化合物进行了定量检测.结果表明,水溶性化合物呈现一定的季节变化趋势.脱水糖类在春、夏、秋、冬的质量浓度分别为132.06,160.58,301.70和244.90 ng/m3,左旋葡聚糖的秋季质量浓度达到234.9 ng/m3,表明存在大量的生物质燃烧;以葡萄糖、蔗糖为代表的糖类化合物主要来源于生长在土壤中的植物,其进入气溶胶中的主要途径是农作物的耕作和收割、风的侵蚀以及交通等,秋季质量浓度较高可能与植物落叶和秸秆燃烧有关;二酸的质量浓度在冬季达到最大值,可能与广州的气象条件有关.广州夏季盛行西南风,降雨较多,而冬季通常逆温少雨,造成二酸质量浓度升高.
