畜禽粪便残留四环素类抗生素的水体污染状况及生态毒理效应

四环素类抗生素是我国畜牧业使用量最大的广谱抗生素之一,因其在动物肠胃系统内难以被完全吸收而在畜禽粪便中残留量较大,导致大量四环素类抗生素随畜禽粪便还田进入土壤,最终进入水环境,并对水环境造成潜在的环境风险。综述了四环类抗生素对我国水体的污染状况及其对水生生物的生态毒理效应,以期为控制该类抗生素对我国水环境的污染提供参考。

Current Situation of Water Pollution Caused by Tetracycline Antibiotics in Animal Manure and Its Ecotoxicological Effect

Tetracycline antibiotics, belonging to broad-spectrum antibiotics, are commonly used in animal husbandry production in China. Due to their low absorptivity in gastrointestinal system, the residues of tetracycline antibiotics are relatively higher in animal manure. The great amount of tetracycline antibiotics is discharged into soil and waterways with animal manure, resulting in potential pollution risk for water environment. Here, we reviewed the current situation of water pollution caused by tetracycline antibiotics in animal manure and its ecotoxicological effect on aquatic organisms, so as to provide references for the control of water environment pollution caused by tetracycline antibiotics in China.
