| Abstract | Hydroxylated polybrominated diphenyl ethers (OH-PBDEs), methoxylated PBDEs (MeO-PBDEs) and PBDEs were determined in three mollusk species collected from three Chinese coastal regions in 2007, 2009, 2010 and 2011. The dominant MeO- and OH-PBDEs isomers detected in mollusks were 6-MeO-BDE-47, 2'-MeO-BDE-68, 6-OH-BDE-47 and 2'-OH-BDE-68. Concentrations of Sigma MeO-PBDEs ranged from 9.20 to 2090 pg g(-1) dry weight (mean: 450 pg g(-1) dry weight). Concentrations of Sigma OH-PBDEs ranged from 118 to 2540 pg g(-1) dry weight (mean: 534 pg g(-1) dry weight). Species differences in accumulation were found for the three mollusk species. Spatial distribution showed that OH- and MeO-PBDEs levels were higher in Weihai than in Tianjin. The temporal trends of OH- and MeO-PBDEs in mollusks were studied during period of 2007 to 2011, rising of Sigma OH-PBDEs in Rap from Penglai and Ost from Weihai and declining of Sigma MeO-PBDEs in Ost in Penglai were observed. Significant correlations were found between OH- and MeO-PBDEs, but neither between PBDEs and OH-PBDEs, nor between PBDEs and MeO-PBDE5, suggesting that OH- and MeO-PBDEs may have a common source or similar accumulation behavior in mollusks. OH- and MeO-PBDE'S were likely not to originate from PBDE precursors. (C) 2013 Elsevier Ltd. All rights reserved. |
