Objective To understand the residual status of pyrethroids and organic phosphorus pesticides in vegetables sold in Qujing City. Methods 80 samples of vegetables were randomly selected and tested for pesticide residues according to the national standard test methods GB / T 5009.145-2003 and GB / T 5009.146-2003. The limit values were evaluated according to GB 2763-2005 “Maximum Residues of Pesticides in Foods”. Results 13 kinds of positive pesticides were detected, and 4 kinds of pesticides were over-standard, namely cyhalothrin, dichlorvos, methamidophos and chlorpyrifos. The total pyrethroid detection rate was 52.5% and the over-standard rate was 2.5%. The total detection rate of organophosphate pesticides was 23.75% and the over-standard rate was 6.25%. Conclusion The vegetable pesticide residues in vegetables in the city are not optimistic. The detection rate of pyrethroid pesticides is high. The monitoring of pesticide residues should be strengthened to ensure the safety of vegetables consumed by the public.
