| 摘 要： | 采用聚氨基甲酸乙酯和玻璃纤维滤膜采集样品并测定。大气中总正构烷烃的浓度分布、气／固分布比与季节变化、污染源有关。在呼市大气中总正构烷烃（Ｃ１５－Ｃ３３），夏季主要存在气态中（７８％），而冬季主要存在于颗粒物上（８３％）。内蒙古草原大气对照样品中，气态中总正构烷烃在冬夏两季所占百分比都约为５０％。市区冬季大气颗粒物上的总正构烷烃浓度比其它城市结果高出１－２个数量级。

| Abstract: | n-Alkanes are found to be present in Urban area,Huhhot and grasslands belt InnerMongolia atmosphere both in the particulate and gaseous state. A polyurethane foam and aglass fiber filter are used to collect vapor and particles sepaately. Dstribution and vapor/par-ticle partitioning are found to be seasonally and pollution dependent.Total n-alkane(C13-C33)concentration measured on the concurring samples are found mainly in the vapor phaseduring summer (78%)in the urban area of Huhhot atmosphere,while most of the total n-alkanes are present in the particulate phase during winter(83%).Precentage of concnetra-tion of total n-alkane(C15-C33)in the particulate and vapor state are approximately 50%for both during summer or winter in the atmosphere of the grasslands belt of lnner Mongo-lia. The levels of the total n-alkanes are one and two order of magnitude higher than thosereported for urban air. |
