Residue levels of seven organophosphorus pesticides in two vegetables (eggplant andcauliflower) collected from major markets of Dhaka city, Bangladesh were analysed. Thecollected samples were analysed using a modified Quick, Easy, Cheap, Effective, Rugged,and Safe (QuEChERS) extraction technique by Gas Chromatography coupled with FlameThermionic Detector (GC-FTD). Among the 50 analysed samples of the eggplant 12%samples contained residues of chlorpyrifos (0.384~0.980 mg/kg), 6% samples containedresidue of dimethoate (0.052~0.132 mg/kg) and 2% samples contained residue of diazinon(0.01 mg/kg). Whereas, among the 50 samples of cauliflower, 12% samples containedresidues of chlorpyrifos (0.056~0.540 mg/kg), 8% samples contained residues of diazinon(0.033~0.42 mg/kg) and 2% samples contained residues of quinalphos (0.06 mg/kg). Thechlorpyrifos was found as the most frequently detected organophosphorus pesticide.Among the 21 contaminated samples, 20 were above EU-MRL. Short and long-termhealth risk assessment based on ARfD and ADI indicates that the intake risks of eggplantand cauliflower were in the acceptable range. Nevertheless, establishing strong monitoringand traceability system together with controlling pre-harvest interval needed to ensurefood safety, consumer confidence and promote vegetable export from Bangladesh.
