Validation Results and Analysis of Organophosphorus Pesticide Residues in Fruit and Vegetable Juice
To monitor laboratory organophosphorus pesticide residue detection capability,participate in nationwide capability verification.The experiment is based on GB 23200.116-2019 national standard,and its method is sim-ply optimized.For a single positive sample,the average of two parallel tests was taken,the standard substance of known concentration was added,and the recovery rate was calculated to reduce the influence of matrix effect on the results.The results showed that the verification results of organophosphorus pesticide residue capability were satis-factory,and the laboratory met the detection requirements,which ensured the reliability of the detection re-sults.After optimization,the experimental operation is simple,and it can be used for daily rapid detection of organ-ophosphorus pesticides in the laboratory.
