摘要:
本文用索氏抽取法提取了东太湖的沉积物和水生植物中的可溶性有机质,用不同极性溶剂在硅胶/氧化铝柱上分离了饱和烃、芳烃、酮馏分,利用GC-MS对芳烃组分进行了鉴定分析,并对其中重要多环芳烃-菲系列化合物的来源进行了探讨.

Abstract:
There has been a g rowing concern in recent years regarding possible harmful effect s to man and other living o rganisms of pollutant organic chemicals released into the environment as a consequence of human activities.Polycyclic aromatic hydrocarbons (PAHs)are one of the mo re significant classes of pollutants, w hich give rise to this concern.This concern arises primarily from the fact that some PAHs generated and released to the environment by human activities have show n to be carcinogenic to mammals.Many researches have been done about the properties of PAHs. PAHs of different molecular weights o r structures vary substantially in their behavior and distribution in the environment and their effects on biological systems.PAHs can be formed mainly in three ways:high temperature pyrolysis of organic materials, low to moderate temperature diagensis of sedimentary organic material to form fossil fuels, and direct biogenesis by microbes and plants. In this paper, the ex tractable lipids were isolated using Soxhlet extraction method in the East Taihu Lake sediment, the ex tracts were fractionated on an activated SiO2/Al2O3 column.The aromatic compounds were w ashed in benzene.Phenanthrene series, one group of important polycyclic aromatic hydrocarbons were analyzed and identified by the GC-MS instrument.The sources of Phenanthrene in Taihu Lake sediment were discussed.Phenanthrene series w ere also found from the aquatic plants with similar composition pattern with that in the East Taihu Lake sediment.This is the first time that aquatic plant s have been singled out as the major source of phenanthrene series in the East Taihu Lake sediments.
