摘    要:珠江三角洲地区主要城市气溶胶中正构烷烃分布可分为3种类型,第一类为前峰型,主要来源于汽车尾气;第二类为后峰型,主要来源于植物蜡;第三类为双峰型,来源于植物蜡,燃料燃烧和尾气。

关 键 词:正构烷烃  分布类型  碳优势指数  植物蜡  气溶胶

Abstract:The distributions of n alkanes in aerosols from major cities in the pearl River Delta can be mainly divided into three types.For the front peak type,its Cmax is C22 or C23 and CPI is approximately 1,mainly with an origin of vehicle exhaust.The behind peak type has a Cmax of C29 or C311 with an origin of plant waxes.The third type is dual distribution.Its Cmax is C25 and C 27 or C29indicating both plant waxes and exhausts or fossil combustion input.The first type appeared in the aerosols collected from traffic zones. The second type usually appeared in cleaning zones and the third type appeared in the rest zones.The results indicate that the distributions of n alkanes in aerosds from the same function zone changed with seasons.
Keywords:n alkanes  distribution types  CPI  Plant waxes  aerosols
