PBDEs (10 congeners) were analyzed using GC-MS in superficial sediments and organisms of the Concepción Bay after the 2010 Tsunami. From all congeners analyzed PBDE-47, -99, -100 and -209 were the most frequently detected. Concentrations (ngg(-1) d.w.) in sediments for ΣPBDE-47, -99, -100 were low (0.02-0.09). However, PBDE-209 showed significantly higher values ∼20ngg(-1) d.w. This result were ∼10 times lower than those reported in a previous study of the 2010 Tsunami. The high result might be influenced by the massive urban debris dragged by the 2010 Tsunami. In organisms, concentrations of PBDE-47, -99, -100 (∼0.4ngg(-1) d.w.) were higher than those found in sediments (∼0.04ngg(-1) d.w.). Differences in PBDE pattern were also observed between different levels of the trophic food chain (primary and secondary consumers). This is the first attempt to assess the current status of Concepción Bay after the 2010 Tsunami.
2010年海啸过后，利用气相色谱 - 质谱联用仪（GC-MS）对康塞普西翁湾表层沉积物和生物体内的多溴二苯醚（10种同系物）进行了分析。在所有分析的同系物中，多溴二苯醚 - 47、-99、-100和 - 209是最常检测到的。沉积物中Σ多溴二苯醚 - 47、-99、-100的浓度（纳克/克干重）较低（0.02 - 0.09）。然而，多溴二苯醚 - 209的值明显更高，约为20纳克/克干重。这一结果比之前一项关于2010年海啸的研究所报告的结果低约10倍。高结果可能受到2010年海啸拖曳的大量城市垃圾的影响。在生物体内，多溴二苯醚 - 47、-99、-100的浓度（约0.4纳克/克干重）高于沉积物中的浓度（约0.04纳克/克干重）。在营养食物链的不同级别（初级和次级消费者）之间也观察到了多溴二苯醚模式的差异。这是首次对2010年海啸后康塞普西翁湾的现状进行评估。
