摘　　要：为筛选出适用于基层市场监管部门监管水果蔬菜等农产品中有机磷农药残留的快速检测方法,本文对酶抑制率法与胶体金免疫层析法进行比较验证,并采用气相色谱法定量检测结果作为准确性判定依据,对两种快检方法检测白菜、黄瓜、胡萝卜等10种蔬菜共30批次样品的结果进行评判。结果表明,酶抑制率法检出限较高,易出现假阴性、假阳性风险,仅适用于果蔬中大剂量有机磷与氨基甲酸酯类农残检测;胶体金免疫层析法灵敏度较高,与气相色谱法检测结果基本相符,可进行单项农药残留的检测,操作简便,检测时间短,适用于基层市场监管部门对果蔬产品中农药残留的快速检测。This article aims to select a rapid detection method suitable for grassroots market supervision departments to monitor organic phosphorus pesticide residues in agricultural products such as fruits and vegetables.The detection limits of enzyme inhibition rate method and colloidal gold immunochromatography method were compared and verified,and the quantitative detection results of gas chromatography were used as the accuracy judgment basis.The results of the two rapid detection methods for detecting 30 batches of 10 types of vegetables,including cabbage,cucumber,and carrot,were evaluated.The results showed that the enzyme inhibition rate method has a high detection limit and is prone to false negatives and false positives.It is only suitable for detecting high-dose organic phosphorus and carbamate pesticide residues in fruits and vegetables.Colloidal gold immunochromatography has high sensitivity and is basically consistent with the detection results of gas chromatography.It can detect single pesticide residues,with simple operation and short detection time.It is suitable for grassroots market supervision departments to quickly detect pesticide residues in fruit and vegetable products.
