  • 摘要: 本文利用气相色谱-质谱/质谱测定了渤海湾南排河海域野生脉红螺肌肉组织中多氯联苯(PCBs)的含量,并对其污染特征进行讨论.结果表明:(1)肌肉中多氯联苯(∑PCBs)总浓度在8.40—10.06 ng·g-1(lw,以脂肪质量计)之间,其中PCB-114含量最高(0.74—1.06 ng·g-1(lw));(2)五氯联苯和六氯联苯为主要检出组分,占∑PCBs的43.7%—84.8%;(3)雌性脉红螺个体中PCBs的平均浓度略高于雄性及性畸变脉红螺中PCBs的平均浓度,分别为(10.06±0.89) ng·g-1(lw)、(8.40±0.63) ng·g-1(lw)和(8.51±0.67) ng·g-1(lw),但性别间无显著性差异.
    Abstract: The present study analyzed the concentrations and distribution pattern of 18 polychlorinated biphenyls (PCBs) in wild Rapana venosa collected from Nanpai river coast in Bohai Bay. After extraction by an accelerated solvent extraction (ASE), total PCBs were determined by gas chromatography-tandem mass spectrometry (GC-MS/MS). The concentrations of PCBs were in a range of 8.40—10.06 ng·g-1 based on lipid weight, and the PCBs congeners showed a similar distribution profile in all samples. The congeners containing 5 to 6 chlorine atoms were the dominant components which accounted for 43.7%—84.8% of total PCBs, in which PCB-114 accounted for the highest percentage in all PCBs congeners. Moreover, the concentrations of PCBs were (10.06±0.89) ng·g-1 (lw), (8.40±0.63) ng·g-1 (lw) and (8.51±0.67) ng·g-1(lw) in females, males and imposex, respectively. No significant difference of PCBs concentrations was observed among different genders.
