【摘要】：目的了解陕西省淡水鱼中孔雀石绿的污染状况,评估陕西居民孔雀石绿的膳食暴露量,对陕西居民通过淡水鱼摄入孔雀石绿的人体健康风险进行评估。方法样品经匀浆提取后采用中性氧化铝固相萃取小柱净化,BEH C18(2.1 mm×100mm,2.5μm)色谱柱分离,利用超高效液相色谱串联质谱法进行含量测定,采用暴露边界比法对陕西省居民通过淡水鱼摄入孔雀石绿的人体健康风险进行评估。结果陕西省淡水鱼中孔雀石绿的检出率为7.32%,最大值为428μg/kg。不同品种淡水鱼中孔雀石绿的检出率差别较大,以鲶鱼中的检出率最高,为28.57%。陕西省十个地市中榆林的检出率最高,为33.33%。结论陕西省淡水鱼中残留的孔雀石绿对人体的健康风险很低,但违规使用孔雀石绿的现象比较严重,相关部门应加强对孔雀石绿的监管力度。
[Abstract]:Objective to investigate the malachite green pollution in freshwater fish in Shaanxi province, to evaluate the dietary exposure of malachite green in Shaanxi residents and to evaluate the human health risk of malachite green ingested by freshwater fish in Shaanxi province. Methods the samples were purified by neutral alumina solid-phase extraction column after homogenized extraction, and separated by BEH C18 (2.1 mm 脳 100mm ~ (2. 5) 渭 m) column. The content was determined by ultrahigh performance liquid chromatography tandem mass spectrometry. The exposure boundary ratio method was used to evaluate the human health risk of the residents of Shaanxi province who ingested malachite green through freshwater fish. Results the detection rate of malachite green in freshwater fish in Shaanxi Province was 7.32 and the maximum value was 428 渭 g / kg. The detection rate of malachite green in different freshwater fish was different, and the detection rate of malachite green was the highest in catfish (28.57). The detection rate of Yulin is the highest in ten cities of Shaanxi Province, 33.33. Conclusion the malachite green residue in freshwater fish of Shaanxi Province is very low to human health risk, but the phenomenon of malachite green using illegally is serious, the relevant department should strengthen the supervision of malachite green.
