A community-based participatory research was utilized to address the coastal community's concern regarding Deepwater Horizon oil contamination of seafood. Therefore, we analyzed polycyclic aromatic hydrocarbons (PAHs), major toxic constituents of crude oil, in the seafood collected from gulf coast (Louisiana, Alabama and Mississippi) during December 2011-February 2014. PAHs were extracted from edible part of shrimp, oysters, and crabs by the QuEChERS/dsPE procedure and analyzed by gas chromatography-mass spectrometry. The total PAHs data were further analyzed using the General Linear Mixed Model procedure of the SAS (Version 9.3, SAS Institute, Inc., Cary, NC) statistical software. Brown shrimp showed statistically significant differences in PAHs levels with respect to time and locations while white shrimp showed differences at various time points. PAHs levels in oyster and crab samples were not statistically different at the Type I error of 0.05. Overall, the PAHs levels are far below FDA levels of concern for human consumption.
本研究采用社区参与式研究方法,以解决沿海社区对深海地平线石油污染海产品的担忧。因此,我们分析了 2011 年 12 月至 2014 年 2 月期间从海湾沿岸(路易斯安那州、阿拉巴马州和密西西比州)采集的海鲜中的多环芳烃(PAHs),这是原油的主要有毒成分。通过 QuEChERS/dsPE 程序从虾、牡蛎和蟹的可食用部分提取 PAHs,并通过气相色谱-质谱法进行分析。使用 SAS(版本 9.3,SAS Institute,Inc.,Cary,NC)统计软件的一般线性混合模型程序进一步分析总 PAHs 数据。棕虾的 PAHs 水平在时间和地点上存在统计学差异,而白虾在不同时间点存在差异。在 0.05 的第一类错误率下,牡蛎和蟹样中的 PAHs 水平没有统计学差异。总体而言,PAHs 水平远低于 FDA 关注的人类食用水平。
