摘要
本文报道了南海东北部红海湾12种海洋动物体内的总石油烃含量。其中,鱼类的总烃含量范围为4.9×10^(-6)～15.0×10^(-6)(干重),平均含量8.62×10^(-6);软体双壳类和头足类的总烃含量分别为21.4×10^(-6)和11.2×10^(-6)。软体双壳类的总烃含量一般比头足类鱼类的高1～3倍。荧光光谱特征分析表明,这些石油烃主要来源于炼制油品(如柴油、机油等)。与国内外其它海域比较,红海湾海洋动物体内的石油烃污染水平是较低的,但其慢性污染对水产资源及渔业的长期效应不容忽视。本文报告的数据可做为该湾海洋动物体石油烃含量的基线值。
Concentrations of total petroleum hydrocarbons (TPHs) in 12 species of marine organisms from the Honghai Bay,northeastern South China Sea were determined with UV-fluorescence' spectrometry for first time.The concentrations of TPHs in fish,bivalve mollusc (oyster)and cephalopod are 8.62,21.4 and 11.2*********ug**********...g-1 dry weight (Dagang crude oil equivalents) respectively.Generally speaking,the concentration of bivalve is 1-3 times greater than that of fish and cephalopod.The fluorescence spectra of petroleum hydrocarbon fraction from the samples determined indicate that refined oil products or light fuel oil may be the major source of oil pollution in the Honghai Bay.In comparison with the TPHs concentrations of marine organisms from other waters off China mainland and some parts abroad,oil pollution level in the organisms from the Honghai Bay is relatively lower.The data reported here may be used as baseline values.
