In the last decades, high concentrations of flame retardants (PBDE) in marine organisms have caused increasing concern among scientists with regards to their biomagnification potential and to human health. Poly-Brominated Diphenyl Ethers have been widely used in the past as flame retardants in various industrial sectors, and their presence in the biota has been associated with different toxicological effects. In this study, concentrations of 9 congeners of PBDE (183, 85, 153, 154, 99, 100, 47, 66 and 28) and morphometric parameters (Total Length, TL; Fork Length, FL in cm and weight) have been measured in muscle of males and females of Atlantic herring (Clupea harengus). Results showed no statistical differences between the concentrations of most of the congeners analysed between the two sexes, except for PBDE 153 (Mean ± standard error in males = 0.034 ± 0.005 μg/kg and in females = 0.086 ± 0.040 μg/kg; p = 0.003). This research contributes to better comprehend the ecotoxicological properties of these molecules and their implications for human consumption.

多溴联苯醚 (PBDEs) 不同同源物在北海 Clupea harengus 雄性和雌性肌肉组织中的生物积累

在过去的几十年里,海洋生物中高浓度的阻燃剂 (PBDE) 引起了科学家们对其生物放大潜力和人类健康的日益关注。过去,多溴二苯醚被广泛用作各种工业部门的阻燃剂,它们在生物群中的存在与不同的毒理学效应有关。在本研究中,测量了 9 种 PBDE 同源物(183、85、153、154、99、100、47、66 和 28)的浓度和形态参数(总长度、TL;叉长、FL(厘米)和重量)在大西洋鲱鱼(Clupea harengus)的雄性和雌性肌肉中)。结果显示,除 PBDE 153 外,两种性别之间分析的大多数同源物的浓度没有统计学差异(男性的平均值 ± 标准误差 = 0.034 ± 0.005 μg/kg,女性 = 0.086 ± 0.040 μg/kg;p = 0.003)。这项研究有助于更好地理解这些分子的生态毒理学特性及其对人类消费的影响。
