Industrial parks are a typical way for economic development in China, which has produced and consumed most polybrominated diphenyl ethers (PBDEs). All samples were collected around an industrial park in May and October 2011, which are extracted XAD-2 and XAD-4 resin and tested by GC-MS (Agilent 7890A/5975C). The mean levels of Σ8PBDE in water, sediment, and soil are 5.53 ng/ml, 37.54 ng/g dw and 22.08 ng/g dw, respectively. In vegetable: Σ8PBDE of leaf, stem, and root in water hyacinth are 35.50 ng/g dw, 52.20 ng/g dw, and 55.30 ng/g dw, respectively; and 44.70 ng/g dw, 37.80 ng/g dw and 95.10 ng/g dw in crabgrass. The level order of organs for vegetables are root > stem > leaf. The levels of PBDE of sediment effect environment more significant than others. The BCF of Σ8PBDE in water hyacinth and crabgrass are 5.46 and 5.15. The mean ΣHQ of PBDE in sediment is 0.25, indicating low environmental risk.
