摘要
多环芳烃(Polycyclic Aromatic Hydrocarbons,PAH)组分中,大多数具有致突变和致癌性。大气、土壤等自然环境中已经检测出了多种多环芳烃。近年来,在河流、内湾及沿岸海域的水体、沉积物中,也检测出了各种多环芳烃。多环芳烃在海洋环境中广泛存在,已经引起了人们的普遍重视。
The wide existence of PAHs in marine environment have caused great concern. Many analytical methods for separation and determination of PAHs in marine environment have been developed.In this paper, Soxhlet extraction and column chromatography were employed to separate the PAHs in marine sediment. The determination of PAHs was made by capillary gas chro-matograph. Identification and quantum of the chromatographic peak were also conducted by utilizing PAHs standards and GC/MS.The recover rate of PAHs standards by this method was in the range of 72-101%. Twenty PAHs were separated and determined in the surface sediment of Tokyo Bay.
