Fish consumption is a potential source of human exposure to pollutants. Here, we study residue levels of PCBs in the eel, Anguilla anguilla, from the Nature Camargue Reserve in southern France. Chromatographic analysis (GC-ECD) found seventy identifiable congeners, among which, 10 are considered as dioxin-like PCBs, such as the non-ortho PCB 81 and the mono-ortho chlorobiphenyls PCB105, 114, 118, 123, 156, 157, 167, 170, 180. Toxic Equivalents (TEQ, WHO 2005 TEF-Toxic Equivalent Factors) varied among sites with a maximum in eels from Mornès (29.6pgg(-1) dry weight). Indicator PCBs (28, 52, 101, 118, 138, 153 and 180) were 22% and 29% of the total PCBs in livers and muscles respectively. Greater homogeneous bioaccumulation in muscle than that in liver suggests an increase risk for humans due to fish consumption.
食用鱼类是人类接触污染物的一个潜在来源。在此，我们研究了来自法国南部卡马尔格自然保护区的欧洲鳗鲡（Anguilla anguilla）体内多氯联苯的残留水平。色谱分析（气相色谱 - 电子捕获检测器）发现了70种可识别的同系物，其中10种被认为是类二噁英多氯联苯，如非邻位多氯联苯81以及单邻位氯联苯多氯联苯105、114、118、123、156、157、167、170、180。毒性当量（TEQ，世卫组织2005年毒性当量因子 - 毒性当量因子）在不同地点有所不同，莫尔内斯的鳗鱼中含量最高（29.6皮克/克干重）。指示性多氯联苯（28、52、101、118、138、153和180）分别占肝脏和肌肉中总多氯联苯的22%和29%。肌肉中比肝脏中具有更强的均匀生物累积性，这表明食用鱼类对人类造成的风险增加。
