GC-MS quantification of organophosphorous pesticides extracted from XAD-2 sorbent tube and foam patch matrices

This work presents a simple extraction procedure and a sensitive and simultaneous gas chromatography-mass spectrometry (GC-MS) method for quantifying five organophosphorous pesticides – chlorpyrifos, dichlorvos, fenchlorphos, parathion-methyl and prothiofos – currently used in flower and ornamental plant greenhouses, extracted from polyurethane foam dermal patches and sampling tubes packed with XAD-2 sorbent and quartz fiber filter.
