The aim of this research is to determine the presence of chlorpyrifos in two varieties of apples: Golden Delicious and Idared in two different locations (Evla and Krveni) from the Resen region in the country. Chlorpyrifos is organophosphate pesticide (insecticide) used to protect apples from insects which can cause significant damage in apple production. The apples are analyzed in four development phases and in each phase the presence of chlorpyrifos is determined. Chlorpiryfos analysis of the apples is performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) followed by an extraction/separation cleansing with acetonitrile and the dispersive SPE - QuEChERS - method. The results are compared with the maximum residue levels (MRL) prescribed by the legislation of the Republic of Macedonia. The conclusion is that chlorpyrifos is variously represented in most phases, regardless of the phase and location where the apple is grown. At certain phase the concentration exceedes MRL, however during the harvest, apples are safe to be consumed. Higher presence of chlorpyrifos is found in Idared apples at Kriveni location as compared to Evla. Тhe presence of chlorpyrifos in Golden Delicious is almost equal in both locations. From the statistical analysis of the data it is noticeable that the use of chlorpyrifos does not depend on the (type) variety of apple but rather on the location where the apple is grown.
