抗生素在环境中的迁移转化及生物效应研究进展

抗生素被长期大量地使用于人和动物的疾病治疗,同时作为饲料添加剂长期使用于畜牧业及水产养殖业。然而,大部分抗生素不能完全被机体吸收,大量的抗生素以原形或代谢物形式经由病人和禽畜粪尿排入环境,经不同途径进入土壤和水体,从而造成环境污染。多项研究显示在城镇废水和地表水中检测到了抗生素的存在,但关于抗生素在环境中的迁移转化及生物效应等研究资料很少。环境中的抗生素会对微生物、水生生物、土壤生物和植物等产生危害,并产生大量耐药菌,影响禽畜等的正常生长,进而对人类健康及整个生态系统构成威胁。为评估抗生素在环境中潜在的危害,本文就抗生素在环境中的迁移转化以及生物效应等多方面进行综述,并提出了今后研究的方向。

A review on Antibiotics Migration-transportation and Biological Effect in Environment

Large quantities of antibiotics are used for human and animals to treat diseases and added into feeds of husbandry and aquaculture for a long time.As results of incomplete absorption,most of them were excreted as original formation or their metabolites together with wastes and they finally through different pathways get into soils and waters to pollute the environment.Recent studies indicate the existence of antibiotics in municipal wastewater and surface water.Meanwhile there is little literature about mig...
