摘要(Abstract)：

多溴联苯醚(polybrominated diphenyl ethers,PBDEs)是土壤-地下水系统中广泛存在的有机污染物,研究土壤组分对其迁移行为的影响是解决土壤-地下水系统中多溴联苯醚归趋问题的关键。以典型多溴联苯醚同系物2,2',4,4'-四溴联苯醚(2,2',4,4'-tetrabromodiphenyl ether,BDE-47)为研究对象,选取胡敏酸(humic acid,HA)、富里酸(fulvic acid,FA)2种代表性土壤有机组分,配制不同浓度的FA、HA溶液(150 mg·L~(-1)、50 mg·L~(-1)),分别对不同浓度的BDE-47(100μg·g~(-1)、10μg·g~(-1))污染土壤进行土柱淋滤实验,探讨FA、HA对土壤-地下水系统中BDE-47迁移的影响。结果表明,HA作用下,实验组下层土壤中BDE-47的残留比例分别为0.62%和0.40%,分别低于对照组的0.72%和3.36%;FA作用下,实验组下层土壤中BDE-47的残留比例分别为6.40%和6.71%,分别高于对照组的0.72%和3.36%。结合HA和FA的元素组成和结构特征分析可知,疏水性强的HA能够促进BDE-47随水流迁移进入地下水系统;亲水性强的FA促进BDE-47在土壤系统中的分布,阻滞了土壤系统中BDE-47进入地下水系统。本文为评估HA、FA对土壤-地下水系统中BDE-47迁移的影响提供依据。
