This study investigated polycyclic aromatic hydrocarbons (PAH) pollution of selected rivers in the Czech Republic. Integrated evaluation was carried out using combination of chemical and biological monitoring, in which we measured content of 1-hydroxypyrene (1-OHP) in chub bile and priority PAH in water samples obtained by exposing the semipermeable membrane devices at each location. The concentrations of 1-OHP in bile samples and sum of priority PAH in water sampler ranged from 6.8 ng mg protein(-1) to 106.6 ng mg protein(-1) and from 5.2 ng L(-1) to 173.9 ng L(-1), respectively. The highest levels of biliary metabolite and PAH in water were measured at the Odra River (the Bohumín site), which is located in relatively heavily industrialized and polluted region. Statistically significant positive correlation between biliary 1-OHP and sum of PAH in water was also obtained (P < 0.01, r s = 0.806).
本研究调查了捷克共和国部分河流的多环芳烃（PAH）污染情况。采用化学监测与生物监测相结合的方法进行综合评估，其中我们测定了在每个地点通过暴露半透膜装置获取的雅罗鱼胆汁中1-羟基芘（1-OHP）的含量以及水样中优先多环芳烃的含量。胆汁样本中1-OHP的浓度和水样采集器中优先多环芳烃的总量分别在6.8 ng mg蛋白质⁻¹至106.6 ng mg蛋白质⁻¹以及5.2 ng L⁻¹至173.9 ng L⁻¹之间。在位于工业化程度相对较高且污染严重地区的奥得河（博胡明站点）测得胆汁代谢物和水中多环芳烃的最高含量。同时还获得了胆汁中1-OHP与水中多环芳烃总量之间具有统计学意义的正相关关系（P < 0.01，r s = 0.806）。
