摘要
氟喹诺酮类抗生素是喹诺酮类的第三代产品,被广泛应用于医疗和养殖。由于氟喹诺酮类抗生素使用量较大,且易被吸附,在环境中的检出浓度均处于较高水平。环境中氟喹诺酮类抗生素的累积对人体健康存在潜在风险,也影响植物的生长、土壤的呼吸和硝化作用等。目前在吸附、光解、氧化、堆肥降解、微生物降解等方面的处理技术研究已取得一定进展,其中微生物降解、光催化、化学氧化法的去除率相对较高、且降解产物的毒性较低,但实际应用到污水处理中还有待进一步的研究。该文对典型的氟喹诺酮类抗生素在环境中的分布、来源、生态毒性的特征及处理技术进行了分析总结,并对后续研究方向进行了展望。
Fluoroquinolone antibiotics,the third generation of quinolones,are widely used in medical and breeding industry.Because fluoroquinolone antibiotics are widely used and easy to be adsorbed,the concentrations of fluoroquinolone antibiotics in environment are relatively high.Accumulation of fluoroquinolones in the environment threats human health potentially,as well as affecting plant growth,soil respiration and nitrification.At present,some progress has been made in the research on treatment techniques of adsorption,photocatalysis,oxidant oxidation,compost degradation,microbial enzyme degradation,and etc.The removal rate of microbial degradation,photocatalysis and chemical oxidation is relatively high,and the toxicity of degradation products is low,but the future research on actual application to sewage treatment is needed.In this paper,the distribution,sources,ecotoxicity characteristics and treatment techniques of typical fluoroquinolone antibiotics in the environment were analyzed and summarized,and the future research directions were prospected.
