畜禽粪污源抗生素污染对土壤和作物的潜在风险及对策

随着我国畜禽养殖业的规模化发展,畜禽粪便排放量急剧增加,致使含有大量兽用抗生素和有抗菌活性的代谢产物排入环境,引起了一系列的潜在生态风险,对人类健康构成了严重威胁。结合我国兽用抗生素使用及其在土壤、植物中的残留现状,对抗生素残留的潜在风险和降解方法进行分析,以期为畜禽粪污的无害化处理和资源化利用提供参考。

Potential Risk of Antibiotic Contamination to Soil and Crops from Livestock and Poultry Manure and Its Countermeasures

Along with the large-scale development of livestock and poultry feeding industry in China, the animal manure emissions have been increasing dramatically. Therefore, a large number of veterinary antibiotics and antibacterial metabolites are discharged into the environment, causing potential ecological risk and making threat to human health. The present situation of veterinary antibiotics using and their residues in soil and plants in China were summarized in this paper, and the potential risk and degradation methods of antibiotic residues were analyzed, so as to provide reference for the harmless disposal and resource utilization of manure from livestock and poultry.
