The aim of the present thesis was a determination of residual agrochemicals in some vegetables, in particular in cucumber and tomato, offered in supermarkets by using high-performance liquid chromatography coupled to tandem mass spectrometry. For separation we used reversed-phase mobile phase composed of aqueous acetonitrile in combination with Zorbax Extend-C18 column. The residues of metalaxyl and mancozeb were found in both products indicating to the use of fungicide formulation Ridomil Gold in their cultivation.
