Water quality and safety are vital to the ecological environment, social development, and ecological susceptibility. The extensive use and continuous discharge of antibiotics have caused serious water pollution; antibiotics are widely found in freshwater, drinking water, and reservoirs; and this pollution has become a common phenomenon and challenge in global water ecosystems, as water polluted by antibiotics poses serious risks to human health and the ecological environment. Therefore, the antibiotic content in water should be identified, monitored, and eliminated. Nevertheless, there is no single method that can detect all different types of antibiotics, so various techniques are often combined to produce reliable results. This review summarizes the sources of antibiotic pollution in water, covering three main aspects: (1) wastewater discharges from domestic sewage, (2) medical wastewater, and (3) animal physiology and aquaculture. The existing analytical techniques, including extraction techniques, conventional detection methods, and biosensors, are reviewed. The electrochemical biosensors have become a research hotspot in recent years because of their rapid detection, high efficiency, and portability, and the use of nanoparticles contributes to these outstanding qualities. Additionally, the comprehensive quality evaluation of various detection methods, including the linear detection range, detection limit (LOD), and recovery rate, is discussed, and the future of this research field is also prospected.
水质与安全对生态环境、社会发展及生态敏感性至关重要。抗生素的广泛使用与持续排放已造成严重的水污染;在淡水、饮用水及水库中广泛发现抗生素;且这种污染已成为全球水生态系统中的普遍现象与挑战,因为受抗生素污染的水对人类健康和生态环境构成严重风险。因此,水中抗生素含量应得到识别、监测与消除。然而,没有单一方法能检测所有不同类型的抗生素,所以常将各种技术结合以产生可靠结果。本综述总结了水中抗生素污染的来源,涵盖三个主要方面:(1)生活污水排放,(2)医疗废水,以及(3)动物生理学与水产养殖。对现有的分析技术进行了综述,包括提取技术、传统检测方法和生物传感器。近年来,电化学生物传感器因其检测快速、高效且便携而成为研究热点,纳米颗粒的使用有助于这些卓越性能的实现。此外,还讨论了各种检测方法的综合质量评估,包括线性检测范围、检测限(LOD)和回收率,并对该研究领域的未来进行了展望。
