Abstract | 本文以采自广州郊区、市区及交通枢纽区的气溶胶样品为对象,首次定量(部分半定量)分析了可溶有机质中烃类、脂肪酸及酮类的组成。广州地区气溶胶类脂物的产率范围10.66 ~ 73.90μg/m~3,主要由燃料残余物、植物蜡及少量的多环芳烃组成。植物蜡组份的存在可由>C23的正构烷烃的锯齿型分布、微量倍半及二萜类(如卡达烯、α-雪松烯)的存在等特征来判定;石油残余物可由低分子量烃类含量增多、总烃中鼓包的存在、地质上成熟的藿烷类及甾类的分布等特征来识别;微生物对气溶胶有机质的贡献主要体现在 |
Other Abstract | Quantitative analysis of the extractable organic matter of aerosols from urban, subarb and heavy-traffic aeras of Guangzhou was made in this dissertation. Lipid yields ranged from 10.66μg/m~3 to 73.90μg/m~3 of air. The extractable organic matter was composed mainly of fossil fuel residues, plant waxes and minor polynuclear aromatic hydrocarbons. Plant waxes can bedistinguished by the saw-tooth distribution pattern of n-alkanes (>C23) and the existence of minor semi- and di-terpanes. The high concentration of low molecular weight hydrocarbons, the existence of hump (UCM) and the geological maturated hopanes and steranes are the characteristics of petroleum residues.
