After the Hebei Spirit oil spill incident (7th December, 2007) in the west coast of Korea, contamination of biliary PAH metabolite and hepatic biomarkers in a pelagic and a benthic fish was monitored for 1 year. Concentrations of 16 PAHs and alkylated PAHs in fish muscle were highest (22.0 ng/g d.w. for 16 PAHs and 284 ng/g d.w. for alkylated PAHs) at 5 days after the spill and then decreased rapidly to background levels at 11 months after the spill. Fish from the oiled site had elevated biliary PAH metabolite concentrations immediately after the spill; these declined steadily in both species, but were still above reference site concentrations 2 months after the spill. Oiled-site fish showed hepatic CYP 1A induction whose trend closely followed those of biliary PAH metabolite concentrations, implying continuous exposure to PAHs. Brain acetylcholinesterase activity was not related to oil exposure.
2007 年 12 月 7 日，河北精神号油轮在韩国西海岸发生泄漏事故后，对洄游鱼类和底栖鱼类的胆汁多环芳烃代谢物和肝生物标志物进行了为期 1 年的监测。在泄漏后 5 天，鱼类肌肉中 16 种多环芳烃和烷基化多环芳烃的浓度最高（16 种多环芳烃为 22.0ng/g 干重，烷基化多环芳烃为 284ng/g 干重），然后迅速下降至泄漏后 11 个月的背景水平。泄漏后，受污染地点的鱼类胆汁多环芳烃代谢物浓度立即升高；这两种物种的浓度都在稳步下降，但在泄漏后 2 个月仍高于参考地点的浓度。受污染地点鱼类的肝 CYP1A 诱导呈上升趋势，与胆汁多环芳烃代谢物浓度的趋势密切相关，这表明它们持续暴露于多环芳烃中。大脑乙酰胆碱酯酶活性与石油暴露无关。
