| 摘 要： | 使用气相色谱-质谱法对2002年7月-2003年7月的北京市大气粗、细颗粒物样品中的左旋葡聚糖等糖类化合物进行了测定。结果表明，左旋葡聚糖主要存在于细颗粒中，可以作为示踪化合物来研究生物质燃烧现象。生物质燃烧对北京市大气颗粒物有较重要的贡献。对应于12％-40％的PM2.5有机碳和10％-33％的PM10有机碳。北京市在2002年10月和11月受到明显的生物质燃烧的影响，可能由于农田秸杆焚烧和秋季落叶焚烧。2003年5月7日颗粒物样品受到直线距离约为1000km以外的内蒙古自治区呼伦贝尔市大兴安岭林区森林大火烟雾的影响。生物质燃烧事件具有突发性，可以长距离传输；生物质作为农村生物燃料的使用其燃烧排放具有经常性和持久性的特征。 |

| Abstract: | Determination of levoglucosan and related saccharidic compounds were carried out using gas chroma-tography-mass spectrometry for two aerosol sample sets, PM2.5 and PM10, which were collected in Beijing during a period of one year from July 2002 to July 2003. The results show that levoglucosan and related compounds were mostly with fine particle fraction. Biomass burning had a significant effect on carbonaceous aerosol in Beijing, accounting for 12%-40% organic carbon in PM2.5, and for 10%-33% organic carbon in PM10. Higher values in October and November were found, which could be attributed to the cornfield burning and the burning of fall- ing leaves in that period. The high levoglucosan value on May 7, 2003 was tracked back to the boreal forest fire more than 1 000 kilometers away in Northeastern China. Biomass burning events are accidental in nature and could be long-range transported. On the other hand, as biofuels in countryside, biomass burning appears a background component of aerosol pollution in North China. |
