Abstract
The levels of organochlorine (OC) pesticide residues in maize grains obtained from open markets and stores in Ile-Ife and Ondo were evaluated and compared with established safety limits. The pretreated samples were Soxhlet extracted and the extracts obtained were analysed for their OCPs content using a Gas Chromatograph coupled with an Electron Capture Detector (GC-ECD). A total of 17 OCPs and their residues were detected in most of the samples with the percentage occurrence ranging between 20 and 100%, and the levels found exceeding their Maximum Residue Limits (MRLs). The mean concentration of l-HCH, Endosulfan II and Endrin aldehyde were 0.118, 0.592 and 1.039 mg kg–1, respectively for maize samples obtained from open markets in Ile-Ife. However, maize samples from Ondo had higher levels of Heptachlor epoxide with a mean concentrations of 13.622 and 18.642 mg kg–1 for open markets and stores, respectively. Amounts of OC pestici...
