【摘要】：目的了解贵阳市市售淡水鱼体内中氟喹诺酮类抗生素(FQs)的残留情况。方法于2015年10—11月,在贵阳市3个水产批发市场(A、B、C区)采集鲤鱼(Cyprinus carpio)、洶鱼(Leiocassis longirostris)、黄搡鱼(Pelteobagrus fulvidraco)、黄蜂鱼(Yellow catfish)、鲈鱼(Lateolabrax japonicus)5种淡水养殖鱼样品,采用超高效液相色谱-串联质谱(UPLC-MS/MS)法检测鱼肌肉组织中7种FQs(恩诺沙星、双氟沙星、诺氟沙星、氧氟沙星、环丙沙星、丹诺沙星、依诺沙星)的残留量。结果淡水鱼体内恩诺沙星和氧氟沙星检出率较高(分别为92.9%和78.6%),平均含量分别为96.5、135.1μg/kg,最高分别为636.2、488.2μg/kg,恩诺沙星超过最大允许限量(50μg/kg),超标率为42.9%;其他6种抗生素检出均较低,且均未检出诺氟沙星。鲈鱼和洶鱼肌肉组织中FQs残留的检出率最高,其中,氧氟沙星和恩诺沙星均检出;黄蜂鱼和黄搡鱼体内检出的残留量均较低,且抗生素残留种类也较少。结论贵阳市场的淡水鱼存在一定程度的FQs污染,应进一步关注氟喹诺酮类抗生素残留量的超标情况。
[Abstract]:Objective to investigate the residues of fluoroquinolones antibiotics (FQs) in freshwater fish in Guiyang city. Methods from October to November, 2015, carp (Cyprinus carpio), was collected from 3 aquatic wholesale markets in Guiyang city (Agni Bu C area) to collect carp (Cyprinus carpio), (Leiocassis longirostris), yellow and jostling (Pelteobagrus fulvidraco), hornet, (Yellow catfish),. Seven kinds of FQs (enrofloxacin, difluracin, norfloxacin, ofloxacin, ciprofloxacin) in fish muscle tissue were detected by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Danofloxacin, enoxacin) residues. Results the detection rates of enrofloxacin and ofloxacin in freshwater fish were higher (92.9% and 78.6%, respectively). The average content of enrofloxacin and ofloxacin in freshwater fish were 96.5135.1 渭 g / kg and 636.2488.2 渭 g / kg, respectively. Enrofloxacin exceeded the maximum allowable limit (50 渭 g/kg) and exceeded the standard rate of 42.9%. Norfloxacin was not detected in all the other 6 antibiotics. The detection rate of FQs residue was the highest in the muscle tissues of perch and bluish fish, ofloxacin and enrofloxacin were detected, and the residues of wasp fish and yellow shoving fish were lower, and the kinds of antibiotic residues were also less. Conclusion there is some FQs pollution in fresh water fish in Guiyang market, and more attention should be paid to the excess of fluoroquinolones residues.
