The effect of a single oral dose of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 10 μg · kg−1, on the status of vitamin A (retinol) was studied in rats during an eight week period after administration. Retinol was determined spectrophotometrically after separation by means of high pressure liquid chromatography.
