土壤环境中抗生素的来源、转归、生态风险以及消减对策

Sources,fate,ecological risks and mitigation strategies of antibiotics in the soil environment

抗生素作为预防、治疗人类和畜禽疾病的药物或促进畜禽生长的添加剂,在世界范围内广泛使用.土壤是抗生素污染的主要归宿,因此土壤环境中的抗生素残留对土壤生态系统的危害已成为普遍关注的热点.本文在已有研究基础上,综述了土壤中不同种类抗生素的来源、转归以及潜在的生态风险,并在此基础上提出了可行的消减对策.

Antibiotics are widely used in the worldwide for the purpose of disease treatment and health protection of human and animals. They are also incorporated into livestock breeding industries to improve growth rate and feed efficiency. Since a significant amount of antibiotics and their bioaetive metabolites or degradation products are introduced into soil environment via different pathways, the research on the adverse effects of antibiotics on the soil ecological environment and public health has become a hot spot. The aim of this review is to explore the sources, fates and ecological risks of antibiotics in soil and the possible strategies promoted to mitigate antibiotic pollution in the environment.
