【摘要】：在上海崇明岛选取15个不同规模的猪场、禽场和奶牛场,分别采集粪肥以及距离养殖场50 m内的地表水、土壤和相应的蔬菜样品,利用液相色谱串联质谱(LC/MS-MS)技术进行氧氟沙星(OFL)、恩诺沙星(ENR)、环丙沙星(CIP)和诺氟沙星(NOR)4种氟喹诺酮类抗生素含量分析,以了解目前上海市崇明岛养殖场周边环境中氟喹诺酮类抗生素的含量水平特征。结果表明,上海市崇明岛养殖场粪肥中氟喹诺酮类抗生素总含量范围为9.00~950μg·kg~(-1),平均值为144μg·kg~(-1),4种抗生素的检出率均在70%以上。周边地表水中氟喹诺酮总含量为2.8~477.5μg·L~(-1),平均值为86.8μg·L~(-1),ENR的检出率为66.7%,OFL、CIP和NOR的检出率均为100%。土壤中氟喹诺酮类抗生素总含量范围为19.1~802μg·kg~(-1),平均值为144μg·kg~(-1),OFL、ENR和CIP的检出率均为100%,NOR的检出率为90.9%。蔬菜中氟喹诺酮类抗生素总含量为ND~110μg·kg~(-1),平均值为21.9μg·kg~(-1)。OFL和CIP的检出率为73.3%,ENR和NOR的检出率为53.3%。养殖场周边环境中氟喹诺酮类抗生素含量均值为粪肥土壤周边地表水蔬菜。对同种氟喹诺酮类抗生素在养殖场周边不同环境介质中含量的相关性分析表明,OFL在粪肥与地表水中的含量呈正相关关系,OFL、CIP、NOR在水样与蔬菜中的含量呈正相关关系。
[Abstract]:Fifteen pig farms, poultry farms and dairy farms of different sizes were selected in Chongming Island, Shanghai to collect manure and surface water, soil and corresponding vegetable samples within 50 m from the farm, respectively. The contents of four fluoroquinolones (OFLX, enrofloxacin, CIPX) and norfloxacin (Norfloxacin) were determined by liquid chromatography tandem mass spectrometry (LC / MS-MS). To understand the content characteristics of fluoroquinolones antibiotics in the surrounding environment of Chongming Island culture farm in Shanghai. The results showed that the total concentration of fluoroquinolones in manure of Chongming Island culture farm in Shanghai was 9.00 ~ 950 渭 g 路kg ~ (-1) 路kg ~ (-1), the average value was 144 渭 g 路kg ~ (-1) 路kg ~ (-1) and the detection rate was over 70%. The total content of fluoroquinolones in peripheral surface water was 2.8N 477.5 渭 g / L, and the average was 86.8 渭 g / L ~ (-1) ENR. The detectable rate of ENR was 66.7% and the detectable rates of CIP and nor were both 100%. The total content of fluoroquinolones in soil was 19.1 ~ 802 渭 g 路kg ~ (-1) ~ (-1), the average value was 144 渭 g / kg ~ (-1) and the detectable rates of OFLENR and CIP were 100% and 90.9% respectively. The total content of fluoroquinolones in vegetables was 110 渭 g / kg, the average was 21.9 渭 g / kg, and the detectable rates of OFL and CIP were 73.3% and 53.3% respectively. The mean value of fluoroquinolones antibiotics in the surrounding environment of farm was manure soil surface water vegetables. The correlation analysis of the content of the same fluoroquinolones in different environmental media around the farm showed that the content of OFL in manure and surface water was positively correlated with the content of OFLCIPNOR in water samples and vegetables.
