Concentrations of products of biotransformation of polycyclic aromatic hydrocarbons (PBPAH) were measured in bile of five fishes of nutritional, cultural and ecological relevance from the Athabasca/Slave river system. Samples were collected in Alberta and the Northwest Territories, Canada, during three seasons. As a measure of concentrations of PBPAHs to which fishes are exposed and to gain information on the nature and extent of potential exposures of people or piscivorous wildlife, concentrations of biotransformation products of two- and three-ringed, four-ringed and five-ringed PAHs were measured using synchronous fluorescence spectroscopy. Spatial and seasonal differences were observed with greater concentrations of PBPAHs in samples of bile of fish collected from Fort McKay as well as greater concentrations of PBPAHs in bile of fish collected during summer compared to those collected in other seasons. Overall, PBPAHs were greater in fishes of lower trophic levels and fishes more closely associated with sediments. In particular, goldeye (Hiodon alosoides), consistently contained greater concentrations of all the PBPAHs studied.
对来自阿萨巴斯卡河/奴隶河系统的5种具有营养、养殖和生态意义的鱼类胆汁中的多环芳烃生物转化产物（PBPAH）浓度进行了测量。样本于三个季节在加拿大艾伯塔省和西北地区采集。为了衡量鱼类接触的PBPAH浓度，并获取有关人类或食鱼野生动物潜在接触的性质和程度的信息，使用同步荧光光谱法测量了二环和三环、四环和五环PAH的生物转化产物浓度。观察到了空间和季节差异，与其他季节采集的鱼类胆汁样本相比，从麦凯堡采集的鱼类胆汁样本中PBPAH浓度更高，夏季采集的鱼类胆汁中PBPAH浓度也更高。总体而言，营养级较低且与沉积物关系更密切的鱼类中PBPAH含量更高。特别是，大眼梭鲈（Hiodon alosoides）一直含有所研究的所有PBPAH的较高浓度。
