In this study, a QuEChERS method and gas chromatography coupled with time-of-flight mass spectrometry (GC×GCTOFMS) was developed for rapid extraction and simultaneous determination of 12 pesticide residues in honey. The GC×GC-TOFMS method was validated according to the SANCO guidance in terms of linearity, selectivity, reproducibility and recovery. Regarding the results, recovery rates ranged between 70-120% with relative standard deviations <20% in most cases. The method Limits of Quantification (LOQ) ranged between 6-26 ng/g. According to the estimated LOQ values the analytical procedure can be applied to analysis of real honey samples.
