  • 摘要: 本工作主要关注北京郊区污水河、地下水及混合水源灌溉的3块农田的表层土壤中,26种多氯联苯(PCBs)和14种多溴联苯醚(PBDEs)的浓度分布特征,并对目标污染物各单体浓度之间的相关性进行了统计学分析.结果显示,所有供试表层土壤样品中共检出26种PCBs(∑26PCBs),浓度水平范围为130—1.93×103 ng·kg-1干重.检出的PCBs种类包括12种共平面多氯联苯异构体(15.6—433 ng·kg-1干重),6种指示型多氯联苯异构体(50.7—452 ng·kg-1干重)和其它8种多氯联苯同系物(52.1—1.15×103 ng·kg-1干重).同时还检出14种多溴联苯醚同系物(∑14PBDEs),浓度水平范围为1.81—14.4 μg·kg-1干重,其中十溴联苯醚(BDE-209)为最主要的组分,约占总组分94%以上.污水河河水和地下水混合灌溉的农田中PCBs和PBDEs的浓度大于地下水灌溉农田中的含量.此外,在所有样品中发现高氯代的多氯联苯同系物(氯原子数≥4)浓度之间存在显著的相关性,可能与灌溉水源和土壤对高氯代联苯的强保留等因素有关.
