Fifty-five biota samples from the Coast of Concepcion (Chile) were analyzed for PBDEs, emerging brominated FRs, halogenated norbornenes and naturally-occurring MeO-PBDEs. PBDEs, MeO-PBDEs and halogenated norbornenes were detected at concentration levels ranging from 11 to 170, nd to 118 and nd to 5.8 ng/g lw, respectively. However, emerging brominated FRs such as decabromodiphenylethane (DBDPE), hexabromobenzene (HBB) and pentabromoethylbenzene (PBEB) were not detected in any sample. Bioaccumulation and bioconcentration processes were evaluated for the different families of compounds. Biomagnification factors (BMFs) were calculated, and some PBDE congeners (BDE-28, BDE-183 and BDE-209) as well as MeO-PBDEs presented BMF>1, being values of the naturally occurring MeO-PBDEs higher than those obtained for PBDEs. As regards halogenated norbornenes, BMF<1 were found.
从智利康塞普西翁海岸采集了 55 个生物群样本，用于分析 PBDEs、新兴溴化阻燃剂、卤化降冰片烯和天然 MeO-PBDEs。PBDEs、MeO-PBDEs 和卤化降冰片烯的浓度范围分别为 11 至 170、未检出至 118 和未检出至 5.8ng/g lw。然而，在任何样本中都未检测到新兴溴化阻燃剂，如十溴二苯乙烷（DBDPE）、六溴苯（HBB）和五溴乙基苯（PBEB）。评估了不同化合物家族的生物积累和生物浓缩过程。计算了生物放大因子（BMFs），一些 PBDE 同系物（BDE-28、BDE-183 和 BDE-209）和 MeO-PBDEs 的 BMF>1，天然 MeO-PBDEs 的值高于 PBDEs 的值。至于卤化降冰片烯，发现 BMF<1。
