Polycyclic aromatic hydrocarbons (PAHs) were analysed in liver of fifty-seven individual trout distributed among seven high mountain lakes in Europe and one remote lake in Greenland. In all cases, very similar distributions were observed in which phenanthrene largely predominated and fluoranthene and pyrene were the second major compounds. These distributions were similar to those observed in the dissolved fraction of the waters studied in three of these lakes. The range of concentrations of PAH in fish liver show only a five-fold variation, which is considerably smaller than the range more than two orders of magnitude of sedimentary PAH concentrations of these lakes. No correlation between PAH content in sediments and fish liver has been found both at the level of total and individual compounds. However, lake site is the main statistically significant factor of variability between PAH concentrations in fish liver. Changes in fish species explain significant differences in liver content of some PAHs. Within lake, condition factor and liver concentration are inversely correlated. Female fish display lower average concentrations than male in all lakes but the differences are not statistically significant. No correspondence between fish age and PAH content has been observed.
对分布在欧洲七个高山湖泊和格陵兰一个偏远湖泊中的57条虹鳟鱼的肝脏进行了多环芳烃(PAHs)分析。在所有情况下,均观察到非常相似的分布,其中菲占主导地位,荧蒽和芘是第二主要化合物。这些分布与在其中三个湖泊所研究水体的溶解部分中观察到的分布相似。鱼肝中PAH的浓度范围仅显示出五倍的变化,这比这些湖泊沉积PAH浓度超过两个数量级的范围要小得多。在总化合物和单个化合物水平上,均未发现沉积物中PAH含量与鱼肝之间存在相关性。然而,湖泊位置是鱼肝中PAH浓度之间变异性的主要统计学显著因素。鱼类种类的变化解释了某些PAHs肝脏含量的显著差异。在湖泊内部,条件因子与肝脏浓度呈负相关。在所有湖泊中,雌鱼的平均浓度均低于雄鱼,但差异无统计学意义。未观察到鱼龄与PAH含量之间的对应关系。
