Abstract
This study was conducted to experiment the removal efficiency of 6 pesticides in fruits and vegetables using various washing solutions. As results, the average removal efficiencies of pesticides washed with tap-water were 68.3%, whereas those washed by ultrasonic cleaning for 2 and 5 minutes were 73.7% and 82.5%, respectively. Using different washing solutions with various additional materials such as 0.5% detergent, 5% vinegar, 5% salt and flour, the removal rates were 82.9%, 76.9%, 75.8% and 75.7%, respectively. With 0.5% detergent, pesticides were 20% more removed when washed by ultrasonic cleaning than tap-water washing; moreover, Chlorthalonil in cherry tomato showed the highest removal efficiency while EPN in grape washed with tap-water showed the lowest. The order of removal efficiencies of pesticides were Chlorthalonil (90.0%)>Procymidone (81.3%)>Chlorpyrifos (76.6 %)>Endosulfan (75.7%)>Fenitrothion (75.5%)>EPN (73.8%).
