中文摘要:采用GC-MS方法对369种中国西部常见蔬菜中51种农药(包括有机磷、有机氯、氨基甲酸酯类、拟除虫菊酯类)进行检测;其中,有机磷农药残留量为0.0008-18.8200 mg/kg,且有五个样本中的有机磷农药残留量超过了最大残留量值;氨基甲酸酯类和有机氯农药残留量为0.0012-0.7928 mg/kg,且分别有六个和四个样本残留量超过了最大残留量值;五种拟除虫菊酯类农药残留量为0.0016-6.0827 mg/kg,且有两个样本残留量超过了最大残留量值。结果显示,70.73%的蔬菜样本中并未检测到农药残留,而其余蔬菜样本中均有一种或者多种农药残留,甚至有些农药残留量超过了最大残留量值,这将会威胁到消费者的健康。本文为控制农药使用的食品安全法规的制定提供了一定的参考。
外文摘要:In this study, an effort has been made to evaluate the pesticide residues in vegetables from western China. Fifty-one pesticides, including organophosphorus, organochlorine, carbamate and pyrethroid, were detected in 369 commonly used vegetables by GC-MS. Concentrations of organophosphorus pesticides were detected ranging from 0.0008 to 18.8200 mg/kg, among which organophosphorus pesticide concentrations exceeded their maximum residue levels (MRLs) in five samples. Carbamate and organochlorine pesticides were determined to have concentrations in the range of 0.0012-0.7928 mg/kg. The residual concentrations of carbamate pesticides in six samples and organochlorine pesticides in four samples exceeded their MRLs. The residual concentrations of five pyrethroid pesticides were within the range of 0.0016-6.0827 mg/kg and the pyrethroid residues in two samples exceeded their MRLs. The results revealed that pesticide residues in 70.73% of the vegetables samples were not detected, while in the rest of vegetables there were one or more pesticide residues and some even exceeded their MRLs, which would threaten the health of consumers. Our work provides significant information for the food safety regulations to control the excessive use of some pesticides on those kinds of vegetables from western China.
