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特征
Contents of Fluoroquinolone-Type Antibiotics in the Surroundings of Livestock Farms in Chongming Island of Shanghai
摘要
Abstract
In order to determine residue levels of fluoroquinolone-type antibiotics in the surroundings of livestock farms in Chongming Island of Shanghai,a total of 15 livestock farms different in size and nature (pig farms,poultry farms,dairy farms) were selected as objects for the study and samples of livestock manure and surface water,soil and vegetable growing within the radius of 50 m of the farms were collected for analysis of contents of ofloxacin (OFL),enrofloxacin (ENR),ciprofloxacin (CIP),and norfloxacin (NOR) using the liquid chromatography tandem mass spectrometry (LC/MS-MS) method.Results show that in the livestock manure samples,total contents of the fluoroquinolone-type antibiotics varied in the range of 9.00-950 μg · kg-1,with an average of 258 μg · kg-1 and over 70％ of the samples were found to contain the four types of antibiotics;in the surface water samples,total contents of the four types of antibiotics varied from 2.8 to 477.5 μg · kg-1,with an average of 86.8 μg · kg-1,and all the samples were found to have OFL,CIP and NOR and 66.7％ to have ENR;in the soil samples,total contents of the four ranged from 19.1 to 802 μg · kg-1,with an average of 144 μg · kg-1,and all the samples were found to contain OFL,ENR and CIP,and 90.9％ to contain NOR;and in the vegetable samples.total contents ranged from ND to 110 μg · kg-1,with an average of 21.9 μg · kg-1,and 73.3％ of the samples were found to have OFL and CIP and 53.3％ to have ENR and NOR.In terms of average content of fluoroquinolone-type of antibiotics the four sectors displayed an order of manure ＞ soil ＞ surface water ＞ vegetable.Correlation analysis shows that the content of OFL in manure was positively related to that in surface water and the content of OFL,CIP and NOR in vegetables to their respective ones in surface water.关键词
