  • 摘要: 测定了辽河干流15个沉积物样品中16种EPA优先控制多环芳烃的含量.结果表明,辽河沉积物中总PAHs含量介于27.8—1479ng·g-1,平均值为285.5ng·g-1,其中蒽、菲、芴含量较高.特征化合物荧蒽/202与茚并[1,2,3,2cd]芘/276的比值表明辽河沉积物中的PAHs主要来源于燃烧产物.
    Abstract: The concentrations of 16 priority pollutant PAHs in the surface sediment samples from Liaohe river were analyzed. The results showed that the total concentrations of PAHs in the sediment samples ranged from 27.8 to 1479ng·g-1 of dry weight, with an average of 285.5 ng·g-1 In all detected PAHs, the concerntrations of phenanthrene,anthracene, fluorine were relatively high According to the observed molecular indices indeno/pyrene/276 and fluoranthene/202, it can be concluded that the dominant source of PAHs in Liaohe river was incomplete combustion of fossil fuel, biomass, coal, etc.
