Our objective is to identify the components of heavy oil (Fuel Oil No 6; i.e. Bunker C) that cause chronic toxicity to fish embryos. Following the 2005 spill of Bunker C into L. Wabamun, AB, it was evident that there are few data on aquatic toxicity to assess the unique ecological risks of oil that sinks and contaminates spawning shoals. Using different exposure scenarios, we will demonstrate bioavailability and toxicity of the components of Bunker C that persist after oil spills and that threaten fisheries recruitment. As well, tests of enhanced chemical metabolism in trout cells in culture, and of chronic toxicity to trout embryos will be combined with chemical analyses of oil fractions to identify those classes of compounds associated with

我们的目标是确定对鱼胚胎造成慢性毒性的重油（6 号燃油；即燃油 C）的成分。 2005 年，Bunker C 泄漏到艾伯塔省 L. Wabamun 后，很明显，几乎没有关于水生毒性的数据来​​评估石油沉没和污染产卵浅滩的独特生态风险。我们将使用不同的暴露场景，证明燃油泄漏后持续存在并威胁渔业补充的燃油 C 成分的生物利用度和毒性。此外，对培养物中鳟鱼细胞化学代谢增强的测试以及对鳟鱼胚胎的慢性毒性的测试将与油馏分的化学分析相结合，以确定与
