The impact of Hurricane Sandy (October 29, 2012) on PAH exposure was investigated in adult Atlantic menhaden (Brevoortia tyrannus) collected along the NJ coast. Collections were made in August, September and/or October of 2011, 2012 and 2013. PAHs were monitored in raw fish oil using excitation-emission matrix (EEM) spectroscopy. Results showed that raw fish oils had relatively high levels of high molecular weight, PAH-like compounds (173 to 24,421ng/mL) compared to values reported for bile in other species. EEM profiles resembled that of crude oil and excluded matrix interference by some common biological molecules that also fluoresce. Concentrations and EEM profiles varied by collection; however, collection ship, month, year and fish size did not account for the data. Replicates showed that fish from the same catch had similar PAH exposure. Overall, Hurricane Sandy did not alter body burdens of PAHs in raw fish oil of menhaden.
2012 年 10 月 29 日的桑迪飓风对成年大西洋鲱鱼（Brevoortia tyrannus）体内多环芳烃暴露的影响进行了研究，这些鲱鱼是在新泽西州沿海采集的。采集工作分别于 2011 年 8 月、9 月和/或 10 月、2012 年和 2013 年进行。利用激发-发射矩阵（EEM）光谱法监测生鱼油中的多环芳烃。结果表明，与生胆汁相比，生鱼油中的高分子量、类多环芳烃化合物的水平相对较高（173 至 24,421ng/mL）。EEM 图谱与原油相似，排除了一些也具有荧光的常见生物分子对基质的干扰。浓度和 EEM 图谱因采集而有所不同；然而，采集船、月份、年份和鱼的大小并不能解释这些数据。重复实验表明，来自同一渔获物的鱼具有相似的多环芳烃暴露水平。总体而言，桑迪飓风并没有改变鲱鱼生鱼油中的多环芳烃的体内负荷。
