摘要
研究了济南地区不同功能区的表层土壤及沉积物中饱和烃的组成和分布特征,在此基础上初步分析了其来源。结果表明,饱和烃主要有正构烷烃、类异戊二烯、环烷烃等组成,正构烷烃碳数分布范围为n-C10—n-C34,类异戊二烯类主要是姥姣烷、植烷及甲基C13—C17烷等,同时还检出烷基环己烷,甾烷、三萜烷及藿烷等环烷烃。饱和烃总体含量分布为北高南低,北部化工区、高速入口处等饱和烃主要来源于原油或成品油等化石燃料及其燃烧产物;南部山区、水库沉积物及农田土壤等饱和烃主要来源于化石燃料的燃烧及高等植物。
The distribution and composition characterization of satured hydrocarbon in Jinan soil and sediment were investigated and the pollution sources were localized.A series of hydrocarbon compounds including normal alkane,isoprenoid,hopanes,steranes and etc.were detected.The distribution of hydrocarbons in north is large than in south.The source includes the rude oils,combustion of fuel and the contribution higher plants.
