抗生素长期大量地被应用于人畜的疾病治疗和水产养殖中,在水体、土壤和沉积物中都有检出。吸附作用是抗生素在土壤/沉积物中重要的环境行为,会影响其在环境中的迁移转化以及对微生物的影响。文章评述了抗生素在土壤氧化物、黏土矿物和有机质上的吸附行为,探讨分析了这些研究中遇到的问题,提出了今后研究的几个重点方向。
Antibiotics are extensively used in human and veterinary treatments. Most of antibiotics are found in waters,soils and sediments. Adsorption is the most important behavior of antibiotics in soils / sediments,which will affect their environmental fate and the effluence on microorganisms. Based on the recent researches in the recent years,a summary is presented on the adsorption of antibiotics onto metal oxides,clay minerals and soil organic matter,and the analyses of problems in studies. Some important research directions in the future are also recommended.
