Intake of trans fatty acid in Japanese university students.

Because trans fatty acids (TFAs) are a potent risk factor for coronary heart disease, it is important to know the amount of TFA consumed. We estimated TFA intakes of Japanese university students by direct measurement. Subjects included 118 students (57 males and 61 females) in two regions of Japan: Kanto (Tokyo area) and Okinawa.

[Behavior of N-methylcarbamate pesticides during refinement processing of edible oils].

The following N-methylcarbamate pesticides, aldicarb, aldicarb sulfoxide, aldicarb sulfone, oxamyl, methomyl, thiodicarb, propoxur, carbofuran, carbosulfan, benfuracarb, bendiocarb, carbaryl, fenobcarb and furathiocarb, were added to soybean oil, each at 5 mg/kg(5 ppm), followed by degumming, alkali refining, bleaching and deodorization for oil refinement. Residual pesticide content in each case was determined immediately after refining. DEGUMMING: Aldicarb, aldicarb sulfoxide, aldicarb sulfone, oxamyl, thiodicarb, carbosulfan, benfuracarb were each found to decrease by as much as 70% by H(3)PO(4) treatment, this being less than 26% noted for the other pesticides.
