摘要：

为了解蔬菜中典型磺胺类药物的残留污染情况，采用高效液相色谱法测定合肥市售的14种蔬菜中3种磺胺类药物含量。结果表明：3种磺胺类药物在14种蔬菜中均有不同程度检出，但不同药物的残留污染状况差异很大。SM2的检出率为97.3%，最高检出浓度为0.5824 mg/kg；SMZ的检出率为24.5%，最高检出浓度为0.0296 mg/kg；SDZ的检出率为22.8%，最高检出浓度为0.0298 mg/kg；不同类别蔬菜中磺胺类药物含量差异大，叶菜类和根茎类蔬菜中磺胺类药物残留污染相对严重；磺胺二甲基嘧啶主要分布在蔬菜的叶片和根部；磺胺嘧啶和磺胺甲噁唑在冬季蔬菜中的检出率明显高于夏季。污染评价表明，蔬菜中磺胺二甲基嘧啶的残留污染情况最严重，超标率高达96.3%；磺胺嘧啶和磺胺甲噁唑的污染情况相对较轻，超标率分别为1.8%和24.5%。由此可见，蔬菜中磺胺类药物的残留污染状况已相当严重。

Abstract:

To investigate typical sulfonamides residues contamination of vegetables, the contents of three sulfonamides in 14 kinds of vegetables sold in Hefei were detected with high-performance liquid chromatography. The results showed that three sulfonamides were detected in vegetables in different levels, but the contamination levels varied significantly with different sulfonamides. SM2 was detected in 97.3% of the samples, the maximum concentration was 0.5824 mg/kg; SMZ was detected in 24.5% of the samples, the maximum concentration was 0.0296 mg/kg; SDZ was detected in 22.8% of the samples, the maximum concentration was 0.0298 mg/kg. The contents of sulfonamides varied significantly in different kinds of vegetables, the contamination of sulfonamides in leaf vegetables and root vegetables was severe; SM2 was mainly distributed in leave and root of vegetable. The detectable rate of SDZ and SMZ in vegetables sold in winter was higher than in summer. The evaluation results showed that the contamination of SM2 was the most serious, the over standard rate was 96.3%; the contamination level of SDZ and SMZ was relatively low, the over standard rates were 1.8% and 24.5%, respectively. The results showed that the residues contamination of sulfonamides in vegetables was serious.
