Applicability of solid phase extraction (SPE) in determination of pesticide residues in cereals
was confirmed by measuring bromophos contents in barley malt. The method entails simple extraction of pesticide
residues from sample with acetonitrile followed by solid phase extraction (SPE) clean-up step prior to the final
determination by gas chromatography with mass spectrometry . It is evaluated that performance of the method,
recoveries bromophos ranged between 80.1 and 129% with associated relative standard deviations between 2 and
13%. Limits of detection of bromophos were less or equal to 0.0013 mg/kg. The applicability of the proposed
method to detect and quantify pesticide residues has been demonstrated in the analysis of 13 real samples. The
findings for bromophos in barley malt samples were bellow the EU regulation MRL value for barley as well as in
conformance with the currently valid regulation of Serbia,
