The removal of fenitrothion (FT) pesticide residues from vegetables by immersion in ozone-microbubbled solution was demonstrated. FT-treated lettuce, cherry tomatoes, and strawberries were immersed in ozone-microbubbled, ozone-millibubbled, and dechlorinated water. After that the percentage of residual FT in the vegetables was determined. Residual FT was efficiently removed from lettuce by immersing it in ozone-microbubbled solution containing more than 1.0. ppm dissolved ozone, or continuously generated ozone-microbubbled solution containing 2.0. ppm dissolved ozone. Similarly, for cherry tomatoes and strawberries, the continuously generated ozone-microbubbled solution containing 2.0. ppm dissolved ozone was highly effective. These results showed that ozone microbubbles effectively removed residual pesticides not only from leafy vegetables but also from fruity vegetables. © 2010 Elsevier B.V.
