Abstract

Residue levels of seven organophosphorus pesticides in two vegetables (eggplant and cauliflower) collected from major markets of Dhaka city Bangladesh were analysed. The collected samples were analysed using a modified Quick Easy Cheap Effective Rugged and Safe (QuEChERS) extraction technique by Gas Chromatography coupled with Flame Thermionic Detector (GC-FTD). Among the 50 analysed samples of the eggplant 12 samples contained residues of chlorpyrifos (0.3840.980 mg/kg) 6 samples contained residue of dimethoate (0.0520.132 mg/kg) and 2 samples contained residue of diazinon (0.01 mg/kg). Whereas among the 50 samples of cauliflower 12 samples contained residues of chlorpyrifos (0.0560.540 mg/kg) 8 samples contained residues of diazinon (0.0330.42 mg/kg) and 2 samples contained residues of quinalphos (0.06 mg/kg). The chlorpyrifos was found as the most frequently detected organophosphorus pesticide. Among the 21 contaminated samples 20 were above EU-MRL. Short and long-term health risk assessment based on ARfD and ADI indicates that the intake risks of eggplant and cauliflower were in the acceptable range. Nevertheless establishing strong monitoring and traceability system together with controlling pre-harvest interval needed to ensure food safety consumer confidence and promote vegetable export from Bangladesh.
