This study evaluated the PAH bioavailability from Santos Bay (Brazil) in 4 species of fish, using PAH biliary metabolites. The collection was done monthly, between July and December, in three different regions of Santos Bay. The metabolites were analyzed through a high performance liquid chromatograph with fluorescence detectors. Total metabolites concentrations ranged from 65.5 to 589μgg of bile, evidencing PAH bioavailability on Santos Bay. Levels of phenanthrene and benzo[a]pyrene metabolites were in the classification range of areas moderate contaminated. Those concentrations were lower in Nebris microps and higher in Sphoeroides testudineus (p<0.05). Naphthalene metabolites concentrations did not differ significantly among fish species and were in the classification range of low contaminated areas. There were no significant spatial and temporal differences in levels among sampled areas. These results are environmentally important given the high levels of urbanization and the absence of biomonitoring data in this area.
本研究使用多环芳烃（PAH）胆甾醇代谢物评估了巴西桑托斯湾 4 种鱼类中的 PAH 生物可利用性。采集工作于 7 月至 12 月间在桑托斯湾的三个不同区域每月进行一次。代谢物通过带有荧光检测器的高效液相色谱进行分析。总代谢物浓度范围为 65.5 至 589μg/g 胆汁，表明桑托斯湾存在 PAH 生物可利用性。菲和苯并[a]芘代谢物的水平处于中度污染区域的分类范围内。Nebris microps 中的这些浓度较低，而 Sphoeroides testudineus 中的浓度较高（p<0.05）。萘代谢物浓度在不同鱼类物种之间没有显著差异，处于低污染区域的分类范围内。在所采样的区域中，水平没有显著的时空差异。鉴于该地区高度城市化且缺乏生物监测数据，这些结果具有重要的环境意义。
