Monterey formation crude oil spilled from an onshore pipeline and entered the surf zone near Refugio State Beach, Santa Barbara County, CA, USA on 19 May 2015. Exposure to nearshore fish was evaluated by measuring biliary polycyclic aromatic hydrocarbon (PAH) metabolite concentrations in surfperch (Embiotocidae), collected near the release point, at a lesser oiled area, Gaviota State Beach, and near the Coal Oil Point oil seep, Campus Point, at both four days and approximately one year after the oil spill. Three to four weeks after the spill, fish, invertebrates, and kelp were collected near the same three sites for PAH analysis of edible tissues to support the fishery closure assessment. Additionally, thirteen days after the spill, vegetation, and invertebrate tissue samples from the seafloor near Refugio State Beach were analyzed for PAHs. In surfperch bile, mean naphthalene, phenanthrene and benzo(a)pyrene metabolite equivalents were significantly higher at Refugio State Beach, compared to Gaviota State Beach or Campus Point in 2015. One year later, there was no significant difference between the three sites. Spatial and depth zone patterns of PAH tissue concentrations from composited invertebrate, vegetation and fish showed highest concentrations were measured in invertebrates collected near Refugio State Beach. Overall, results show elevated PAH levels in nearshore organisms and provide a useful reference for potential PAH exposures in fish and subtidal invertebrates following a large nearshore oil spill.

在 Refugio Beach 漏油后在鱼类和潮下带无脊椎动物中测量的胆汁多环芳烃代谢物当量

2015 年 5 月 19 日,蒙特利地层原油从陆上管道泄漏并进入美国加利福尼亚州圣巴巴拉县 Refugio 州立海滩附近的冲浪区。通过测量冲浪鲈鱼中胆汁多环芳烃 (PAH) 代谢物的浓度来评估近岸鱼类的暴露情况(杀虫科),在漏油事件发生后的四天和大约一年后,在泄漏点附近、油污较少的地区加维奥塔州立海滩和煤油点石油渗漏点校园点附近收集。泄漏后三到四个星期,在相同的三个地点附近收集鱼、无脊椎动物和海带,用于可食用组织的 PAH 分析,以支持渔业关闭评估。此外,在泄漏 13 天后,对来自 Refugio 州立海滩附近海底的植被和无脊椎动物组织样本进行了 PAH 分析。在 surfperch 胆汁中,与 2015 年的 Gaviota State Beach 或 Campus Point 相比,Refugio State Beach 的平均萘、菲和苯并 (a) 芘代谢物当量明显更高。一年后,三个地点之间没有显着差异。来自复合无脊椎动物、植被和鱼类的 PAH 组织浓度的空间和深度区域模式显示,在 Refugio 州立海滩附近采集的无脊椎动物中测量到最高浓度。总体而言,结果显示近岸生物体内 PAH 水平升高,并为大型近岸石油泄漏后鱼类和潮下带无脊椎动物的潜在 PAH 暴露提供了有用的参考。
