Current contamination levels of selected legacy, currently-used and emerging halogenated contaminants were monitored in marine shellfish along French coastlines. The studied contaminants included polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDDs), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), decabromodiphenylethane (DBDPE), hexabromobenzene (HBB), 2,2′,4,4′,5,5′-hexabromobiphenyl (BB-153) and perfluorinated compounds (PFCs).BDE-47, BDE-209, BTBPE, HBB and α-HBCDD were detected in 100% of the analyzed samples, whereas BB-153, DBDPE and PFOS were detected at frequencies of 97%, 90% and 55%, respectively. Concentrations were in the pg g−1 ww range and varied as follows: PFOS > BDE-47 ∼ α-HBCDD > BDE-209 > BTBPE ∼ DBDPE > HBB ∼ BB-153. Overall, non-PBDE Brominated Flame Retardants (BFRs) revealed concentrations between 3 and 59 times lower than those of PBDEs.PBDE pattern was dominated by BDE-47, followed by BDE-99 > BDE-100 > BDE-49 > BDE-209 > BDE-154; these 6 congeners represented 94% of the summed ten PBDEs. PFC pattern determination revealed PFOS as the predominant PFC in samples from the English Channel and Atlantic, whereas perfluorocarboxylic acids (PFCAs) prevailed in Mediterranean samples. Temporal trend investigations on archived samples from the Mediterranean coast collected between 1981 and 2012 showed a prevalence of PFOS until 1998; PFCAs subsequently increased and became more abundant than PFOS. High levels of PFCAs were observed until 2008, followed by a decrease and stabilization in 2010–2012. Amongst PFCAs, perfluorotridecanoic acid (PFTrDA) and perfluoroundecanoic acid (PFUnA) were predominant and exhibited similar time trends, suggesting similar sources at the investigated site, home to major industrial activity.
本研究沿法国海岸线监测了海洋贝类中选定的传统、当前使用和新兴卤代污染物的当前污染水平。所研究的污染物包括多溴二苯醚（PBDEs）、六溴环十二烷（HBCDDs）、1,2-双（2,4,6-三溴苯氧基）乙烷（BTBPE）、十溴二苯乙烷（DBDPE）、六溴苯（HBB）、2,2′,4,4′,5,5′-六溴联苯（BB-153）和全氟化合物（PFCs）。BDE-47、BDE-209、BTBPE、HBB 和 α-HBCDD 在分析的 100%样本中均有检出，而 BB-153、DBDPE 和 PFOS 的检出频率分别为 97%、90%和 55%。浓度在 pg g-1 ww 范围内变化，如下所示：PFOS>BDE-47∼α-HBCDD>BDE-209>BTBPE∼DBDPE>HBB>BB-153。总体而言，非多溴二苯醚阻燃剂（BFRs）的浓度比 PBDEs 低 3 至 59 倍。PBDE 模式以 BDE-47 为主，其次是 BDE-99>BDE-100>BDE-49>BDE-209>BDE-154；这 6 种同系物占总和的 10 种 PBDE 的 94%。通过对样品中全氟化合物（PFCs）模式的测定，结果表明在英吉利海峡和大西洋的样品中 PFOS 是主要的全氟化合物，而在地中海的样品中则是全氟羧酸（PFCAs）占主导地位。对 1981 年至 2012 年间收集的来自地中海沿岸的存档样本进行的时间趋势研究表明，PFOS 一直占主导地位，直到 1998 年；随后 PFCAs 增加并变得比 PFOS 更丰富。直到 2008 年，PFCAs 的水平仍很高，随后在 2010 年至 2012 年期间下降并稳定下来。在 PFCAs 中，全氟十三酸（PFTrDA）和全氟十一酸（PFUnA）占主导地位，且表现出相似的时间趋势，这表明在研究地点存在类似的来源，该地点是主要工业活动的所在地。
