抗生素常用于预防动物疾病和提高牲畜生产力。然而，其释放到周围环境中会导致生态干扰和对人类健康的风险。本研究的目的是监测韩国猪粪堆肥设施附近的水、沉积物和土壤中抗生素的发生和季节变化。各种类型的抗生素，如四环素（TC），包括四环素，金霉素，土霉素，和磺胺类药物（SA），包括磺胺二甲嘧啶，磺胺甲恶唑，并通过固相萃取的高效液相色谱-串联质谱测定。结果表明，水体、沉积物和土壤中抗生素的浓度随季节变化而变化。观察到的浓度水平的TC在冬季高于夏季，表明低温是一个参数，其在水，沉积物和土壤中的降解中断。SA的浓度水平显著高于TC，一般而言，与其他国家相比，韩国所有测量的抗生素浓度也普遍较高。因此，有必要对水生和陆生环境中抗生素的残留进行长期监测。
Antibiotics have been commonly used to prevent animal diseases and promote livestock productivity. However, its release into the surrounding environments leads to ecological disturbance and risks to human health. This study was conducted to monitor the occurrence and seasonal variations of antibiotics in water, sediment, and soil close to a swine manure composting facility, Korea. Various types of antibiotics such as tetracyclines (TCs) including tetracycline, chlortetracycline, and oxytetracycline, and sulfonamides (SAs) including sulfamethazine, sulfamethoxazole, and sulfathiazole were measured by the high-performance liquid chromatography-tandem mass spectrometry via a solid-phase extraction. In the results it was identified that the variations of measured antibiotics' concentrations in water, sediment, and soil are depending on the season. The observed concentration levels of TCs were higher in winter than in summer season, indicating that the low temperature is a parameter attributing to interruption of its degradation in water, sediment, and soil. The concentration levels of SAs were significantly higher than those of TCs and in general, all measured antibiotics' concentrations were also in general higher in Korea when compared to those in other countries. The long-term monitoring of antibiotics' residues in aquatic and terrestrial environments is necessary.
