The aim of this research is to determine the presence of chlorpyrifos in two varieties of
apples: Golden Delicious and Idaret on two different locations (Evla and Krveni) from 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 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 Idaret apples at Kriveni location compared to Evla. Тhe presence
of chlorpyrifos in Golden Delicious is almost equally in both locations. From the statistical analysis of
the data it is noticeable that the use of chlorpyrifos doesn’t depends on the (type) variety of apple but
rater of the location where the apple is grown.
