Abstract:
Objective To estimate the application of the wheat esterase inhibition method for the determination of organic phosphorus pesticide residues in agricultural products.Methods The wheat esterase inhibition method was used for the determination of organic phosphorus pesticide residues in chive,the quality evaluation and principal component analysis were conducted.Organic phosphorus pesticide residues in five agricultural products were detected by this method,and compared with the confirmatory test with GC.Results The detection limit,standard deviation,relative standard deviation and average recovery of this method for various organic phosphorus pesticides were 0.05-0.52 mg/kg,0.26-3.09,2.9%-4.1% and 74.5%-92.1%,respectively.The inhibitory degree of pesticide and precision was the primary factor for influencing the result of quality evaluation.Conclusion The wheat esterase inhibition method is reasonable and is applicable for the semi-quantitative analysis of organic phosphorus pesticide residues in the agricultural products
