Abstract:
Objective To evaluate the efficiency of different wash methods for removing organophosphorus pesticide residues from cucumber. Methods The cucumber samples were soaked with tap water, washed rice water, salt solution and detergent solution respectively for 2 to 15 minutes then organophosphorus pesticide residues in the soak water samples were determined with ultrasonic extraction and gas chromatography. Results Soaked in tap water for 2 to 5 minutes was the most effective and convenient way to remove methamidophos and dimethoate with the highest removing rate (about 70%). Conclusion Soaked with tap water for 2 to 5 minutes is more efficient for removing organophosphorus pesticide residues from vegetable.
