- Abstract
Dairy milk has a high incidence of contamination with persistent insecticides residues. Contamination of milk with a pesticide depends on its stability, its mode of application, the duration of the intake or exposure and its metabolic fate in the animal. Pesticides are extracted from solvents such as acetonitrile, petroleum ether, hexane, dichloromethane, or acetone. Cleanup of hexane extract with official method, SPE extraction, Acetonitrile petroleum ether followed by Florisil cleanup, QuEChERS (MSPD), extraction with hexane partitioned with acetonitrile and dichloromethane. The solvent is blended with the sample and homogenized. Pesticide compounds are separated either on gas chromatography (GC) or liquid chromatography (LC), and then identified and quantified using Electron-capture detection (ECD), flame photometric detection (FPD), nitrogen-phosphorus detection (NPD), fluorescence detection, and diode-array detection (DAD) depending on the molecules to be analysed. But role of GC and LC coupled with mass spectrometry (MS) and tandem mass spectrometry (MS/MS) in pesticide residue analysis is clear in both monitoring and research applications.
