中文摘要：
用GC-NCI-MS测定了浙江台州路桥表层农业土壤中41种多溴二苯醚（PBDEs）的含量,并对其分布及来源进行了分析.结果表明：所有样品中Σ41PBDEs的含量为0.193～91.0ng/g,平均值为8.96ng/g,其中BDE209的含量为0.0452～61.5ng/g,平均值为5.41ng/g.在多数样品中十溴BDE及九溴BDEs是主要的同族体,四溴和七溴BDEs同族体次之.同族体组成特征和聚类分析表明,多数采样点主要受到deca-BDE工业品的污染,另有一些采样点受到octa-BDE和deca-BDE工业品的污染,个别采样点主要受到penta-BDE工业品污染.与国内外相关研究相比,研究区域内土壤中PBDEs的污染水平较低,但少数采样点受点源污染影响较大.
英文摘要：
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.
