1生物质燃烧颗粒物有机示踪化合物的测定和应用显示文摘使用气相色谱-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1000 km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。张烃 刘咸德 董树屏 祁辉 Hélène Cachier Magda Claeys 2006岩矿测试2006,25,2:17
2Characteristics of Carbonaceous Particles in Beijing During Winter and Summer 2003显示文摘运动被进行在冬季和夏天期间在 PM_(2.5 ) 测量器官的碳(OC ) 和元素的碳(EC ) 2003 在北京。PM_(2.5 )andPM_(10 ) 的谦虚差别意味着集中在冬季和夏天运动之间被观察。在两个季节的 meanPM_(2.5 )/PM_(10 ) 比率在 60% 附近,显示显著地贡献到 PM_(10 ) 的 PM_(2.5 ) 。在 PM_(2.5 ) 的 OC 和 EC 的吝啬的集中是 11.2 ± 7.5 和 6.0 ± 5.0 μ g m^( 为冬季运动的 -3) ,和 9.4 ± 2.1 和 4.3 ± 3.0 μ g m^( 为夏天运动的 -3) 分别地。日报在 PM_(2.5 ) 的 OC 和 EC 的集中在冬季在白天期间在夜里和 low 被发现高,并且在夏天下午由明显的最小描绘了。Themean OC/EC 比率是 1.87 ± 0.09 为冬季和 2.39 ± 0.49 为夏天。在夏天的更高的 OC/EC 比率显示第二等的器官的碳(SOC ) 的某形成。估计的 SOC 是 2.8 μ g m^( 为冬季和 4.2 μ g m^ 的 -3)( 为夏天的 -3) 。于建华 陈添 Benjamin GUINOT Helene CACHIER 虞统 刘文清 王欣 2006Advances in Atmospheric Sciences2006,23,3:13
3雪冰黑碳的气候效应研究显示文摘黑碳气溶胶沉降到雪冰表面后,使雪冰反照率降低从而导致气候增暖的效应日益引起人们的关注。首先提出了雪冰黑碳的气候效应问题,然后介绍了国际上相关研究的进展,并提出加强此项研究对提高中国区域气候认识的意义。明镜 效存德 秦大河 Helene Cachier 2006气候变化研究进展2006,2,5:8
4Seasonal characteristics of biomass burning contribution to Beijing aerosol显示文摘110 atmospheric aerosol samples collected from November 1997 to October 1998 at two monitoring sites (Ming Tomb and Temple Heaven) in Beijing were analyzed for the con-centration of organic carbon (OC) and water-soluble potassium (K+). Four biomass burning epi-sodes, namely spring farming, summer harvesting, autumn harvesting and leaf falling were iden-tified using the tracer of K+. Biomass burning contribution to the urban aerosol OC concentration in Beijing was estimated by regression analysis of OC and K+ concentration data. The slopes of regression analysis are similar at the two monitoring sites, presenting regional characteristics. Severe air pollution event occurred during autumn harvesting period in 1998 with substantial secondary OC formed, in which biomass burning was one of the major emission sources. Bio-mass burning is a prominent source of aerosol OC in Beijing and is featured by its seasonality and periodicity. It may contribute as much as 30 to 60 percent of the total OC in typical cases.Cachier H. 2005Science China Chemistry2005,48,5:4
