Marketed vegetables and fruits contaminated by organophosphorus, organochlorine, or carba-mate pesticides were cut into several regions (fruit stalk, pericarp, fruit receptacle, tissue around the stalk cavity, etc.) and the concentration of the pesticide residues in each region was assayed. In fruits and fruit-type vegetables, the concentra-tion of the pesticide residue was higher in the fruit stalk and near the epidermis (exocarp and fruit receptacle) than in the sarcocarp or peri-carp. In leaf vegetables, the concentration of the pesticide residue was higher in the outer leaves than in the inner ones. There was no pesticide contamination of the inner leaves of Chinese cab-bages with a well-formed head. Dieldrin and heptachlor epoxide were detected in pumpkins and cucumbers, although their use in agriculture has been prohibited in Japan for about 20 years. The removal rates of pesticide residues by washing with water or 0.1% liquid detergent for kitchen use were from 8 to 52% and from 19 to 67%, respec-tively. Removal of the fruit stalk, exocarp, and tissue around stalk cavity of fruits and fruit-type vegetables and washing of leaves with water or dilute detergent solution for kitchen use were necessary to decrease the intake of pesticide resi-dues from vegetables and fruit.

エビを亜硫酸塩類溶液に浸漬し漂白を行うと, ホルムアルデヒド (FA) が生成することを確認し, 漂白条件と生成量の関係, エビ中に含まれるトリメチルアミンオキシド (TMO) とFA生成の関連性などについて検討した. FA生成量は亜硫酸濃度と共に増加し, 1.5%以上で一定となった. 1.5%溶液での処理を繰り返すと, さらにFAが生成した. エビを透析した外液をTLCにより分画し, TMOが存在する画分からのみ, FAが生成することを確認した. 透析液に亜硫酸水を加えるとFAが生成し, FA生成とTMOの減少との間には量的な相関関係が見られた. このことから, TMOがFA生成の要因であると考えられた.
