摘要
以鄱阳湖流域的袁河为研究区,以常用的磺胺类、四环素类、喹诺酮类、硝基咪唑类和大环内酯类等五大类抗生素,共计27种抗生素为研究对象,采用优化后的固相萃取前处理-液质联用仪检测法检测抗生素,对袁河流域典型抗生素的分布、来源及生态风险进行研究。结果表明,袁河水体中抗生素广泛存在,有20种抗生素被不同程度地检测出,其中磺胺类和硝基咪唑类的检出率达到了100%,养殖废水和生活污水是袁河流域抗生素的主要来源。研究区抗生素的分布特征与区域内的养殖业发展和社会活动存在一定联系。对袁河水体的12种抗生素进行了生态风险评价,结果表明,克拉霉素处于高风险,红霉素、土霉素、恩诺沙星和磺胺噻唑处于中等风险,其余为低风险或无风险。
This paper chooses Yuanhe River in the Poyang Lake basin as study area.27 types of commonly-used antibiotics,including sulfonamides,tetracyclines,quinolones,nitroimidazoles and macrolides,were selected as research objects.The presences of the antibiotics were detected by employing an optimized solid-phase extraction pretreating-liquid mass spectrometry method,and the distribution,origin and ecologic risk of the typical antibiotics were investigated.Results showed that antibiotics widely occurred in Yuanhe River with 20 kinds of antibiotics being detected at various levels.Among them,sulfonamides and nitroimidazoles had a detection rate reaching 100%.Breeding wastewater and domestic sewage were determined to be the main sources of antibiotics in the Yuanhe River basin.The distribution characteristics of antibiotics were related to the prosperity of breeding industries and social activities in this region.Results of ecological risk assessment of 12 types of antibiotics in the Yuanhe River water body showed that clarithromycin would pose a high risk;erythromycin,oxytetracycline,enrofloxacin and sulfathiazole would pose a medium risk;the rest antibiotics would pose low risk or no risk.
