两种类型的溴化阻燃剂（溴化阻燃剂）的浓度：多溴联苯醚（PBDEs）和多溴联苯（PBBs）的测定在一个单一的年龄级的湖鳟鱼（Salvelinus namaycush）从劳伦特五大湖在1997年。安大略湖样本中多溴二苯醚总平均浓度最高，为95 +/- 22纳克/克湿重或434 +/- 100纳克/克脂重，而埃里克湖鳟鱼中的浓度最低（27 +/- 8.6纳克/克湿重和117 +/- 37纳克/克脂重）。在所有样本中，主要的多溴二苯醚同系物是2，2 '，4，4'-四溴二苯醚（BDE-47）、2，2 '，4，4'，5-五溴二苯醚（BDE-99）和2，2 '，4，4'，6-五溴二苯醚（BDE-100），它们是常用的五溴二苯醚配方阻燃剂的主要成分。从休伦湖采集的湖鳟体内的多溴联苯浓度最高（3.1 +/- 1.7纳克/克湿重，15 +/- 8.5纳克/克活重），而在上级湖的鱼类体内检测到的浓度最低（0.25 +/- 0.13纳克/克湿重，1.7 +/- 0.89纳克/克活重）。在所有湖鳟样本中，阻燃剂FireMaster BP-6（R）的主要成分2，2 '，4，4'，5，5 '-六溴代二苯（BB-153）是主要的多溴联苯同系物。(C)2002爱思唯尔科技有限公司。保留所有权利。
Concentrations of two types of brominated flame-retardants (BFRs); polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) were determined in a single age class of lake trout (Salvelinus namaycush) collected from the Laurentian Great Lakes in 1997. Mean concentrations of total PBDE were highest in samples from Lake Ontario at 95 +/- 22 ng/g wet weight (ww) or 434 +/- 100 ng/g lipid weight (lw) while the lowest concentrations were observed in Lake Eric lake trout (27 +/- 8.6 ng/g ww, 117 +/- 37 ng/g lw). In all samples, the predominant PBDE congeners were 2,2',4,4'-tetrabromodiphenyl ether (BDE-47), 2,2',4,4',5-pentabromodiphenyl ether (BDE-99), and 2,2',4,4',6-pentabromodiphenyl ether (BDE-100), which are the primary components of the commonly used penta-BDE formulation flame retardant. Lake trout collected from Lake Huron had the highest concentrations of PBBs (3.1 +/- 1.7 ng/g ww, 15 +/- 8.5 ng/g lw), while the lowest levels were detected in fish from Lake Superior (0.25 +/- 0.13 ng/g ww, 1.7 +/- 0.89 ng/g lw). In all lake trout samples, 2,2',4,4',5,5'-hexabromobiphenyl (BB-153), a major constituent of the flame-retardant FireMaster BP-6(R), was the predominant PBB congener. (C) 2002 Elsevier Science Ltd.
