| Abstract: | There has been a growing concern in recent years regarding possible harmful effects to man and other living organisms of pollutant organic chemicals released into the environment as a consequence of human activities. Polycyclic aromatic hydrocarbons (PAHs) are one of the more significant classes of pollutants, which 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 shown to be carcinogenic to mammals. Many researches have been done about the properties of PAHs. PAHs of different molecular weights or 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 extractable lipids were isolated using Soxhlet extraction method in the East Taihu Lake sediment, the extracts were fractionated on an activated SiO 2/Al 2O 3 column. The aromatic compounds were washed 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 were 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 plants have been singled out as the major source of phenanthrene series in the East Taihu Lake sediments. |
