Abstract

Removal efficiency of pesticide residues by washing with detergent was studied by use of Komatsu-na (Brassica chinensis L.), which was cultivated on the experimental farm and had been sprayed either with lead arsenate or BHC. This efficiency was calculated by the ratio of the sum of pesticide found in the washing solution and the rinsing water to these values found in the unwashed vegetables. Almost complete removal of arsenic and lead was achieved through detergent washing. This efficiency for BHC by detergent washing was about 2.5 times higher than that by water washing. And the effect of rinsing following detergent washing was found to be significant.
