Background: This study evaluates the quantitative assessment of
persistent organochorine pesticide (OCPs) residues in vegetables (Senecio biafrae) from four selected
cocoa plantations in Ekiti State, Nigeria. Methods: The pesticides were
extracted from the vegetable samples by using USEPA 3500C method and later
clean-up on activated silica gel. The pesticides residues in the samples were
determined using Gas Chromatography coupled with Electron Capture Detector
(GC-ECD). Results: The results showed that the analyzed samples were
contaminated with ten OCPs. The mean OCPs concentration ranged from ND—0.399 mg/kg to ND—0.379 mg/kg during the wet
and dry seasons respectively.
