The present investigation aimed to analyze PBDE and PCB contamination in mussels (Perna perna) and two commercially important fish species, croaker (Micropogonias furnieri) and mullet (Mugil liza), in the Guanabara Bay, the most important Brazilian estuary, by gas chromatography coupled to mass spectrometry, in order to further knowledge regarding these compounds in the southern hemisphere. This is also the first report of PBDE in this mussel species in the Guanabara Bay. Fish were captured in September (dry season, winter) and March (wet season, summer) 2007 and September 2008. Mussels were collected in August (dry season, winter) 2006, in February (wet season, summer) 2007, and in August 2007 (winter). The results show that all samples showed higher PCB contamination when compared to other ecosystems around the world. On the other hand, PBDEs presented lower concentrations in 41 % of the samples. Croakers presented the highest PCB and PBDE levels, with mullet showing intermediary values and mussels, the lowest.
本研究旨在通过气相色谱-质谱联用分析巴西最重要的河口之一瓜纳巴拉湾贻贝（Perna perna）以及两种商业上重要的鱼类，美洲犬牙石首鱼（Micropogonias furnieri）和棱鳀（Mugil liza）体内的多溴联苯醚（PBDE）和多氯联苯（PCB）污染情况，以便进一步了解南半球这些化合物的情况。这也是首次在瓜纳巴拉湾贻贝中报告 PBDE。鱼类于 2007 年 9 月（旱季，冬季）和 3 月（雨季，夏季）以及 2008 年 9 月捕获，贻贝于 2006 年 8 月（旱季，冬季）、2007 年 2 月（雨季，夏季）和 2007 年 8 月（冬季）采集。结果表明，与世界其他生态系统相比，所有样本的 PCB 污染都更高。另一方面，41%的样本中 PBDE 的浓度较低。美洲犬牙石首鱼和棱鳀的 PCB 和 PBDE 含量最高，贻贝的含量最低。
