Cypermethrin assessment and possible persistence in grapes or wines

Abstract

The use of insecticides in crops is needed to provide an increase of production at relatively low cost. Lately increased chemisationto crop led to problems in the food, but also directly with animal health or in directly to human consumption. In the present work we propose to study such a substance, namely cypermethrin, which is used widely by human society. The method used is sensitive (SBSE-GC-MS) with a limit of ppb-level for identification and quantification relatively wide interval. We try to eliminate the intermediate steps in order to reduceother influences. Results showed the presence of these substances in grapes, but in relatively low concentrations and lack of it to wine, below the quantification limit of 1 ppb
