摘　　要：活性材料覆盖法已经被证明具有修复沉积物疏水性有机化合物(HOCs)的潜力。活性材料覆盖法利用活性材料的强吸附能力降低了HOCs生物可利用性,与此同时活性覆盖层有效地阻止沉积物中HOCs向上层水体扩散。然而,活性材料覆盖层可能会对沉积物中的底栖群落(微生物和无脊椎动物)的结构和生理功能造成不利的影响。该文从修复机制、材料选择、工程参数及对底栖群落的影响等方面对覆盖法进行综述,并指出活性材料覆盖法未来的研究方向可着眼于活性材料的生物亲和力、功能多样性和环境友好性。The capping approach by active material has shown potential on sediment remediation for hydrophobic organic contaminants(HOCs).The active materials with high adsorption capacity can reduce the bioavailability of HOCs,meanwhile,the active material caps block the diffusion of HOCs from sediment to the upper water.However,the active material caps may adversely affect the structure and physiological functions of benthic communities(microbe and invertebrate).The remediation mechanism of capping approach including material selection,engineering parameters and its influence on benthic communities were reviewed.Furthermore,it described future improvements of active materials with emphasis on biological affinity,functional diversity and environmental friendliness.
