Determination Of Pesticides In Apples, Grapes And Apple Juice From A Kosovo Market By Gradient Liquid Chromatography With Tandem Mass Spectrometry

摘要

Apple, grape, and apple juice were analyzed for pesticides using a multireaction mode (MRM) method in samples taken from a Kosovo market. With this method it was possible to analyze about 100 pesticides in the ESI mode. In these samples some types of pesticides were found, but most of them did not exceed the maximum tolerance levels. In apple samples, six pesticides were detected but only three of them were in sufficient quantitites. Dimethoat was below the limit, while acephate and imazalil exceeded the limit. In grape and apple juice samples, all of pesticides which were found did not exceed the maximum tolerable limits.
