Abstract：The concentrations of 41 polybrominated diphenyl ethers (PBDEs) in the agricultural soils from Luqiao were analyzed by GC-NCI-MS,and their distribution and possible sources were also investigated. The total concentrations of 41 PBDEs (Σ41PBDEs) in soils ranged from 0.193 to 91.0 ng/g dry weight, with a mean of 8.96 ng/g,and the concentrations of BDE209 were from 0.0452 to 61.5 ng/g dry weight, with a mean of 5.41 ng/g. Deca-BDE and nona-BDEs were the predominant homologues in most of samples, followed by tetra-BDEs and hepta-BDEs. The homologue composition and cluster analysis showed that most of sampling sites were polluted by deca-BDE formulation, and others polluted by octa-BDE and deca-BDE formulations. Comparing with other studies, the levels of PBDEs in the present study were lower, but it should be concerned that a few of sampling sites were highly contaminated.
