In the present study, a simultaneous sample preparation method for determination of 3-monochloropropane-1,2-diol (3-MCPD) and polycyclic aromatic hydrocarbons (PAHs) in different foodstuffs has been evaluated. Sample procedure involved acetonitrile extraction/partitioning cleanup by dispersive solid phase extraction with final detection gas chromatography coupled mass spectrometry. The experiment demonstrated that freezing out extracts prior to (d-SPE) step gave better results removal undesirable matrix constituents although slightly lower recovery values. addition higher amount MgSO4 contributed increased values hydrocarbon recovery, contrast 3-MCPD which recoveries were insignificantly when was added. Finally, chromatographic measurement revealed quantification PAHs not effective due signal enhancement resulted from presence derivatisation products. However, presented concept can be streamlined an interesting analytical approach providing good validation parameter values: within range 50–110 % 76–107 3-MCPD, precision exceeding 16.5 7.7 limits than 0.9 μg kg−1 9.3 3-MCPD.
