| 摘 要： | 采用高效阴离子交换色谱-脉冲安培检测(HPAEC-PAD)分析方法,对北京城区PM2.5和PM10中糖类化合物进行定量分析.在北京大气气溶胶中共检出14种糖类化合物,分为脱水糖、糖和糖醇共3大类.脱水糖包括左旋葡聚糖、甘露聚糖和半乳聚糖;糖包括葡萄糖、果糖和海藻糖;糖醇包括阿拉伯糖醇、甘露糖醇、丙三醇、苏糖醇、2-甲基丁四醇(2-甲基苏糖醇和2-甲基赤藓糖醇)、木糖醇和肌醇.脱水糖来源于生物质燃烧,秋冬季节的浓度水平明显高于春夏;而来源于生物源排放的糖和糖醇,冬季浓度水平明显低于其它季节.PMF源解析结果表明,北京大气气溶胶中糖类化合物的来源主要可以分为6类,包括生物质燃烧、异戊二烯SOA、土壤悬浮、真菌孢子、花粉及丙三醇富集源.

| Abstract: | Based on the newly established high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD), the saccharides in PM2.5 and PM10 in Beijing from 2011-2012 were quantified. Fourteen saccharides were synchronously detected in the aerosols samples in Beijing, which can be divided into three categories, i.e. anhydrosugar, sugar and sugar alcohol. Anhydrosugar, coming from biomass burning, include levoglucosan, mannosan and galactosan. Sugar and sugar alcohol, emitted by the primary biogenic emission, include glucose, fructose, trehalose, arabitol, mannitol, glycerol, threitol, 2-meythltrtols (2-methylthreitol and 2-methylerythrito), xylitol and inositol. The concentrations of monosaccharide anhydrides in summer and autumn were obviously higher than those in spring and winter, while the concentrations of sugar and sugar alcohol in winter were significantly lower than those in other seasons. The results of positive matrix factorization analysis suggested that saccharides compounds in atmospheric PM in Beijing can be derived from biomass burning, suspended soil or dust, isoprene SOA, as well as direct release of airborne fungal spores and pollen. |
