Low pg levels of PBDD/Fs in 0.8-38.9 pg g(-1) (fat) range (mean 14.2 pg g(-1)) observed in the tested cod liver samples were significantly lower than levels of their chlorinated analogues (25.1-95.9 range, 37.7 mean pg g(-1) fat). Brominated furans dominated the congener profile. Elevated levels of OH-/MeO-BDE were however observed with mean concentrations at 2769±1319 and 5441±2918 pg g(-1) (fat) respectively. The observed congener profiles with the predominance of 6-OH-BDE 47 and the relatively high proportion between the native and hydroxylated compounds indicate on natural origin of those compounds or at least presence of various exposure sources. A large fraction of studied samples did not comply with the currently standing EU regulations concerning PCBs and chlorinated dioxins (11%), especially as regards non-dioxin like PCBs (88%).
在所检测的鳕鱼肝脏样本中，多溴二苯并二恶英/多溴二苯并呋喃的低皮克水平在0.8 - 38.9皮克/克（脂肪）范围内（均值为14.2皮克/克），显著低于其氯化类似物的水平（范围为25.1 - 95.9，脂肪中均值为37.7皮克/克）。溴代呋喃在同系物分布中占主导。然而，羟基/甲氧基多溴二苯醚水平升高，其平均浓度分别为2769±1319和5441±2918皮克/克（脂肪）。所观察到的以6 - 羟基多溴二苯醚47为主导以及天然化合物与羟基化化合物之间相对较高比例的同系物分布表明这些化合物源于天然，或者至少存在多种暴露源。很大一部分研究样本不符合欧盟现行关于多氯联苯和氯化二恶英的法规要求（11%），特别是非二恶英类多氯联苯（88%）。
