摘要
Abstract
Objective: To determine the 6 residues including organophosphorus, organochlorinated and pyrethroid pesticides simultaneously in crude yam slices,yam slices stir-fried with bran and sulfur fumigation yam. Methods: The compounds were ready for GCMS analysis after being extracted with acetonitrile and purified. Determinations were performed with selected ion monitoring mode and external standard method was adopted in the quantificaticon . Results: The contents of 6 kinds pesticides residue had good linear correlation with the peak area in the rang of 0. 01 ~0. 5μg/mL. The average recoveries of 6 kinds pesticides residue were 87. 5 % -95. 5%. The method detection limits ranged from 0. 002 ~ 0. 005 μg/g. Organochlorine and pyrethroid pesticides were detected in the three samples except the parathion residue. Conclusion: Stir-fried with bran and sulphur fumigation had nearly no effects on the pesticides residue in yam. The method is sensitive and accurate and can be used in determination of multiresidual pesticides residue in yam.关键词
