摘  要：
采用气相色谱法(GC-NPD,ECD)测定毒死蜱和氰戊菊酯残留量,研究了菠菜(Spinacia oleracea L.)和不结球白菜(Brassicaca mpestris L.ssp.Chinensis Makino var.communis Tsen et Lee)中毒死蜱、氰戊菊酯的残留动态。结果表明,菠菜中毒死蜱残留量、不结球白菜中毒死蜱和氰戊菊酯残留量存在着明显的基因型差异。同一不结球白菜基因型,毒死蜱和氰戊菊酯的残留量达到《GB2763-2005食品中农药最大残留限量》中规定的叶类蔬菜农药最大残留限量所需要的时间存在明显差异,且毒死蜱达到最大残留限量所需要的时间比氰戊菊酯长,因此在选择低农药残留基因型时,应首先考虑农药残留时间长、最大农药残留限量低的农药品种。菠菜品种sp0723、卡尔以及不结球白菜品种矮抗青、无锡605和青选3号属于低农药残留的基因型,在生产上推广应用有利于提高叶类蔬菜的食用安全水平。

摘  要：
The residues of chlorpyrifos and fenvalerate were determined by GC(Gas Chromatograph)with NPD or ECD detector. The dynamics of chlorpyrifos residue in spinach,chlorpyrifos and fenvalerate residues in pakchoi were investigated in this experiment. The results indicated that the chlorpyrifos residue in spinach,and the residues of chlorpyrifos and fenvalerate in pakchoi were obviously different among genotypes. In the same genotype of pakchoi,the time of chlorpyrifos and fenvalerate residues accorded with MRL (maximum residue limits)of leafy vegetables stipulated in "GB 2763—2005 maximum residue limits for pesticides in food" was evidently diverse,the time of chlorpyrifos MRL was longer than that of fenvalerate. As a result,more time of pesticide residue and pesticide variety of low MRL were in the first place considered in the way of selecting genotypes with low pesticide residue. The varieties sp0723 and Kaer of spinach,and Aikangqing,Wuxi605 and Qingxuan No.3 of pakchoi belong to the genotypes with low pesticide residues,applying these varieties to farming will be helpful for improving security level of leafy vegetables.
