The aim of the present study was to evaluate polycyclic aromatic hydrocarbon (PAH) contamination of the major rivers in the Czech Republic using 1-hydroxypyrene (1-OHP) content in chub bile as a biomarker. The highest concentration of 1-OHP was found in the Otava River at Topělec (80.5 ng mg protein(-1)); the lowest content of 1-OHP was found in the Vltava at Zelčín (9.6 ng mg protein(-1)). At all sites, bottom sediment samples were collected and analyzed for PAH content. The PAH content ranged between 1.2 and 15.2 mg kg dry mass(-1) at all sites. Statistically significant positive correlations (p < 0.05) between biliary 1-OHP and sediment PAH content were found. Correlation coefficients for total and individual priority PAHs ranged from 0.63 to 0.77.
本研究旨在通过检测鲤鱼胆汁中 1-羟苊（1-OHP）的含量，评估捷克共和国主要河流中多环芳烃（PAH）的污染情况。在 Topělec 的奥塔瓦河（Otava River）中发现了最高浓度的 1-OHP（80.5ngmg 蛋白(-1)）；在 Zelčín 的伏尔塔瓦河（Vltava）中发现了最低浓度的 1-OHP（9.6ngmg 蛋白(-1)）。在所有地点均采集了底泥样本并进行了 PAH 含量分析。在所有地点，底泥中的 PAH 含量范围在 1.2 至 15.2mgkg 干质量(-1)之间。在胆汁中 1-OHP 和底泥中 PAH 含量之间发现了统计学上显著的正相关（p<0.05）。总优先 PAH 和单个优先 PAH 的相关系数范围在 0.63 至 0.77 之间。
