摘要:
应用建立的QuEChERS样品前处理,四级杆–飞行时间质谱筛查,三重四极杆串联质谱确证的方法,对广州市某大型水产市场的42种52个水产样品进行了7类59种药物残留的筛查。结果表明,被抽查的样品中,有5类12种药物被检出,阳性检出率为50.0%,不合格率为38.5%,其中黄鳝样品检出恩诺沙星2229 μg•kg−1、甲氧苄啶228 μg•kg−1,桂花鱼检出隐性孔雀石绿400 μg•kg−1,宝石斑鱼检出氢化可的松45.3 μg•kg−1,花斑鱼检出醋酸氢化可的松22.3 μg•kg−1,白贝检出土霉素21.8 μg•kg−1。在一定范围内反映了广州水产品安全方面的有用信息。

Abstract: Based on the method that samples were pretreated by QuEChERS sample preparation, then screened with quadrupole tandem time-of-flight mass spectrometry, and confirmed using triple quadrupole mass spectrometry, an investigation of veterinary residues related to 59 compounds was carried out to 52 aquatic products from Guangzhou aquaculture market. The stastics indicated that the positive samples accounted for 12 kinds from 5 species, and the positive rate was 50.0%, while 38.5% samples within these exceeded the range of the national standard, agricultural standards or trade standards. The detective content of several remarkable positive samples was given as follows: 2229 μg•kg−1 for enrofloxacin and 228 μg•kg−1 for trimethoprim in mud eel, 400 μg•kg−1 for leucomalachit green in Chinese perch, 45.3 μg•kg−1 for hydrocortisone in jade perch, 22.3 μg•kg−1 for hydrocortisone acetate in Epinephelus maculates, and 21.8 μg•kg−1 for oxytetra-cycline in Monetaria moneta (Linnaeus). This survey gave us some useful information about aquatic products security of Guangzhou in some way.
