中文摘要: 为研究清洗处理对蔬菜中农药残留的影响,选择3种不同类型的蔬菜品种,设置3个农药浓度组分别为空白、低浓度、高浓度组进行田间喷施试验,在安全间隔期后进行采收,对比3种蔬菜中灭蝇胺、咪鲜胺及其代谢物的去除效果。结果表明,3种蔬菜清洗后的加工因子均小于1,其中灭蝇胺的去除率为25.61%~66.00%,三聚氰胺的去除率为14.69%~89.74%,2,4,6-三氯苯酚的去除率为20.69%~50.73%。综上,清洗可以去除2种农药及其代谢物,但达不到完全去除,其中灭蝇胺的去除效果较咪鲜胺更好。
Abstract:This paper investigates the effect of washing on pesticide residues in vegetables.To be specific,three types of vegetables were selected and high-concentration,low-concentration,and blank groups were designed for the spraying of pesticides.Then,after the pre-harvest interval,the vegetables were harvested,and the removal of cyromazine,prochloraz,and their metabolites in the three vegetables was compared.The results showed that the processing factors of all the three vegetables were less than 1 after the washing,and the removal rates of cyromazine,melamine,and 2,4,6-trichlorophenol fell in the range of 25.61%-66.00%,14.69%-89.74% and 20.69%-50.73%,respectively.In summary,washing decreased the residues of the two pesticides and their metabolites in vegetables,particularly cyromazine.
