Abstract:
Background and Objective: Preservation of agricultural products remains a hallmark of all farmers as a result, both pesticides and herbicides are being applied during planting and after harvesting with the sole aim of maximizing profits. Research had shown the various degree of toxicity of organochlorine pesticides residues, the objective of the research was to identify the organochlorine pesticide residues, analyze their risk assessment vis-a-vis, Hazard Index (HI), Estimate Dietary Intake (EDI), Target Hazard Quotient (THQ) and compare the results with Acceptable Dietary Intake (ADI), Reference dose standard (Rfd) and Maximum Residue Limit (MRL) and characterized the identified organochlorine pesticides residue for their toxicological properties. Materials and Methods: Phaseolus vulgaris were purchased in a local market in Igbara -Oke, Ondo state Nigeria, the sample was powdered using a grinder (Sumeet CM/L 2128945) and solid phase extraction techniques were employed, the extract was subjected to fractionation into two fractions of aliphatic hydrocarbons and the pesticides. The pesticide extract was subjected to characterization using gas chromatography-mass spectrophotometer. Results: Total 4 organochlorine pesticide residues were identified and the contaminant rates (mg kg–1) were less than 1. Furthermore, EDI values were lower than the ADI, MRL, also, the THQ values were less than 1, an indication that the Phaseolus vulgaris was safe for consumption. Conclusion: The research had shown no toxicity of the Phaseolus vulgaris purchased from the local market and it shows compliance by the local farmers on the application of pesticides to the food crop by obeying the recommended dose.
