三峡重庆库区PAHs污染研究

Research on PAHs pollution of the Three Gorges Reservior in ChongQing

使用GC-MS对三峡地区重庆段河流中的多环芳烃污染进行了分析研究.共检出萘、苊、二氢苊、芴、菲、蒽、萤蒽、芘共8种多环芳烃,其浓度均在0.7μg/L以下,推测其主要来源于燃料燃烧.其中检出率高是菲、芘、萤蒽3种多环芳烃,它们在每个水取样均有检出,应该予以关注.

The Polycyclic Aromatic Hydrocarbons pollutionof the Three Gorges reservior in ChongQmgnas been researchedin this article. Eight kinds of Polycyclic Aromatic Hydrocarbons were identified in water samples. They were naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene and pyrene. The concentration of them were not more than 0.7μg/L, and it speculated that the main source of them was the combustion of fuels. The compounds of higher rates detected were phenanthrene, pyrene and fluoranthene, which can be detected in each water sample, more attention should bepaid on them.
