Development of a Gas Chromatography - Tandem Mass Spectrometry Procedure for Determination of Pesticide Residues in Honey and Honeybee Samples

Abstract

A new anal. procedure of detn. of multiresidue of pesticides based on application of the modified QuEChERS approach at the step of sample prepn. and technique GC-MS/MS has been developed and applied for studies the real honey and honeybee samples. Samples were collected from northern Poland (Pomerania). The proposed procedure enables for the detn. of 34 and 30 pesticide residues resp. in honey and honeybee samples. The recovery of analytes was between 70 and 120% with relative std. deviation ≤ 20%. The limits of quantification were in the range of 2.3-27 ng/g and 2.2-29 ng/g resp. for honey and honeybee samples. The proposed procedure was proven to be a powerful, highly sensitive, and environmentally friendly anal. tool that requires minimal sample prepn. [on SciFinder(R)]
