Resumen

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.
