Levels and distribution of methoxylated and hydroxylated polybrominated diphenyl ethers in plant and soil samples surrounding a seafood processing factory and a seafood market
چکیده انگلیسی

Polybrominated diphenyl ethers (PBDEs) along with hydroxylated polybrominated diphenyl ethers (OH-PBDEs) and methoxylated polybrominated diphenyl ethers (MeO-PBDEs) were found in plant and soil samples collected surrounding a seafood processing factory and a seafood market in China. The profiles of MeO-PBDE congeners were different between seafood processing factory and seafood market. The detection frequency and concentration of 6-OH-BDE-47 were lower than that of MeO-PBDEs. Near seafood processing factory, a decreasing trend of analyte concentrations in plants was found downstream the river where factory wastewater was discharged. Concentrations of ΣMeO-PBDEs in plant and soil samples showed difference as root > soil > leaf. However, at seafood market, the concentrations of ΣMeO-PBDEs were much higher in leaves than those in soil. The concentration of ΣMeO-PBDEs in leaves showed a remarkable difference between Calystegia soldanella (Linn.) R. Br. and Setaira viridis (L.) Beauv.


► We detected MeO-PBDEs and OH-PBDEs in plants surrounding seafood factory and market.
► MeO- and OH-PBDEs in terrestrial plants and soil are mainly from marine products.
► Contact with seafood, root uptake and leaves adsorption are accumulation pathways.
► Species differences caused different level distribution of MeO-PBDEs in plants.
