Abstract: Ethiopia is a country whose half of GDP lies on agricultural products. It is the birthplace of coffee Arabica. The use of pesticide is increasing worldwide, and particularly among rural populations of the developing world whose economy relies mostly in agriculture. Thus, contamination of the environment with pesticides and the pesticides entry into the food chain is unavoidable especially in developing countries. A study was conducted to investigate Organochlorinated pesticides residue levels in coffee beans commodities from Oromia region, Ethiopia. HRGC/HRMS was used for the determination of 23 organochlorine pesticides compounds in all samples. The extraction and clean up were done based on QuEChERS methods with slightly modification. ∑HCH, ΣAldrin, heptachlor, Endrin, ΣChlordane and Mirex were not detected in all of green coffee beans. Gamma-HCH, heptachlor, trans-chlordane, o,p'-DD, p,p'-DDE, o,p'-DDD, p,p'-DDD, o,p'-DDT and p,p’-DDT were detected at BQL. DDT and their metabolites were detected in most of coffee samples ranged 0.062ng/g to 51.7ng/g. Para, para’-DDT isomer was the dominant contaminant in green coffee beans. Our finding results obtained in this study provide vital information for the control and address further significance of researches on Organochlorinated pesticides in Ethiopia.
