摘  要:
[Objective]The aim was to optimize the 1stand 2ndpretreatment methods of NY / T 761-2008"Multi-pesticide Residues Determination of Organophosphorus,Organochlorine,Pyrethroid and Carbamate Pesticides in Vegetable and Fruit". [Method] The residues of organophosphorus,organochlorine and pyrethroid pesticides in vegetables were detected by using external standard method and GC which contained FPD detector and ECD detector. [Result] The recovery of standard addition of 41 kinds of pesticides in vegetable samples was 86. 29%-102. 96%,and the coefficient of variation was 2. 11%- 8. 02%,and both them were in accordance with demand of pesticide residue analysis. [Conclusion] The method is more efficient and simple than old method,and uses less solvent,so it is more accordance with demand of modern environmental and harmless detection.
