Polybrominated diphenyl ethers (PBDEs) are potentially harmful and persistent environmental pollutants. PBDEs concentrations are reported in plant, shellfish and sediment samples collected from Chinese Laizhou Bay. The ∑11PBDE concentrations in plant and shellfish samples from Laizhou Bay were in the range of 70–5900 ng g−1 and 230–720 ng g−1 lipid, respectively. The ∑11PBDEs concentrations in river sediment intervals samples ranged from 1.3 to 1800 ng g−1 dry weight. Pearson correlation analyses were performed on concentrations of PBDEs congeners of different sediment sample intervals. There were significant positive correlations for BDE 28 and BDE 100 (r = 0.945, p < 0.01), BDE 47 and BDE 99 (r = 0.879, p < 0.01), BDE 153 and BDE 154 (r = 0.934, p < 0.01), nona-BDEs and BDE 209 (r > 0.934, p < 0.01). BDE 209 was the predominant congener in all analyzed samples, consistent with the fact that deca-BDE technical mixtures are the dominant PBDEs product in Laizhou Bay. Data showed that PBDEs should be considered as an increasing pollution problem in the Laizhou Bay region.
