深圳市淡水鱼类中孔雀石绿及结晶紫残留状况的调查分析

深圳市淡水鱼类中孔雀石绿及结晶紫残留状况的调查分析
目的  调查分析深圳市市售水产品鱼类中孔雀石绿及其代谢物、结晶紫及其代谢物的残留情况。   方法  样品依据GB/T 19857-2005经超高效液相色谱-串联三重四极杆质谱法(ultra performance liquid chromatography-triple quadrupole mass spectrometry, UPLC-MS/MS)测定样品中的孔雀石绿、隐性孔雀石绿、结晶紫、隐性结晶紫。结果  300份鱼类样品孔雀石绿及其代谢物的检出率为1.67% (5/300)、结晶紫及其代谢物的检出率为23.67% (71/300); 500份鱼养殖水样品中结晶紫及其代谢物的检出率为0.6% (3/500), 孔雀石绿及其代谢物无检出。不同种类养殖鱼间比较, 鲈鱼、生鱼、黄骨鱼的检出率均在36%以上。结论  深圳市在售鱼类中存在孔雀石绿/结晶紫及其代谢物检出率高而暂养水检出率低的情况, 因此鱼类运输、批发零售环节添加孔雀石绿/结晶紫的可能性较小, 养殖环节的滥用值得关注。

Objective  To investigate and analyze the residues of malachite green and its metabolites, crystal violet and its metabolites in the fishes of aquatic products in Shenzhen. Methods  According to GB/T 19857-2005, the content of malachite green, hidden malachite green crystal violet and recessive crystal violet in samples were determined by ultra-performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS). Results  The detection rate of malachite green and its metabolites in 300 fish samples was 1.67% (5/300), and the detection rate of crystal violet and its metabolites was 23.67% (71/300); The detection rate of crystal violet and its metabolites in 500 fish culture water samples was 0.6% (3/500), and malachite green and its metabolites were not detected. Among the different types of farmed fish, the detection rates of carp, raw fish, and yellow bone fish were all above 36%. Conclusion  The detection rate of malachite green/crystal violet and its metabolites in the sale of fish in Shenzhen is higher than the detection rate of temporary water. Therefore, the possibility of adding malachite green/crystal violet to fish transportation in whole sale and retail links is relatively low, and the abuse in breed tache should deserve attention.
