摘要

Background: The study determined the presence and concentration of persistent organochlorine pesticides (OCPs) residues in cow milk from Ekiti State University Agricultural farm in Ado-Ekiti, Nigeria. The study was investigated in order to monitor consumer’s exposure to these chemicals pesticides. Methods: Qualitative identification and quantification evaluation of the extracted pesticides after clean-up on silica gel were done with a Gas Chromatography coupled with an Electron Capture Detector (GC-ECD). Results: The results revealed the presence of 11 OCPs residues in the milk samples, with concentration range of 0.001 - 0.189 mg/l, while α-BHC, endrin, endrin aldehyde, endosulfan II, endosulfan sulphate and methoxychlor were not detected. The analysis of variance revealed no significant variation in the levels of all the analysed pesticides except dieldrin. Conclusion: The hazard indices (HIs) were significantly lower than 1 with the range of 0.00063 - 0.107, indicating no potential health risk.
