Determination of Selected Pesticide Residues in Tomato by Using GC - MS, Collected from Kebridehar and Gode Markets, in Somali Region, Ethiopia

Abstract

Pesticides are commonly employed by local farmers and government entities in Ethiopia for pest control. The goal of this study was to determine the residue of organochlorine and organophosphorus pesticides in tomato samples taken from the Somali region of Ethiopia's Kebridehar and Gode markets. Ten tomato samples were gathered from local marketplaces in Kebridehar and Gode, Ethiopia, and examined for pesticide residues. Standard protocols were followed for sample collection and preparation. GC-MS was used to assess the concentrations of pesticide residues. The samples were extracted utilizing the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) approach, which included the use of a dispersive solid phase extraction cleanup process. AOAC procedure 2007.01 was used to clean up the sample extract.The samples were analyzed for organochlorine and organophosphorus pesticide residues such as  α-BHC, β-BHC, γ‑BHC
