ABSTRACT
In the present study a multiresidue method was standardized and validated for the quantification of or-ganochlorine pesticides (OCPs) in meat samples. Sample extraction was performed by adopting QuEChERS principle and the extracts were cleaned-up by dispersive solid-phase extraction with primary secondary amine after salting out with NaCl and MgSO4. Analysis was carried out by gas chromatography-mass spectrometry. The performance of the method was investigated in terms of precision, linearity, accuracy, detection limit and quantification limit (LOQ). As per SANTE guidelines, 2017 good linearity was obtained, with correlation coefficients (r2) equal to 0.999. Mean recoveries were found in the ranges 70-120%. The study concluded that developed method was standardized and validated and found to be rapid, simple and reliable for analysis of pesticide residues in meat samples.Keywords: GC-MS, meat, multiresidue analysis, OCPs, QuEChERS
