title: Tissue distribution and elimination of 2,8-dihydromirex in the rat.
abstract: The tissue distribution and elimination kinetics of 14C-labeled dihydromirex were investigated in the rat. Dihydromirex was distributed in all tissues examined after iv or oral administration; the highest concentrations were found in the fat, liver, and skin. The pattern of distribution was similar to that of photomirex and mirex. Elimination of dihydromirex from the blood after an iv dose was expressed by a four-compartment model, whereas fecal excretion was represented by a biphasic curve. Excretion of dihydromirex occurred predominantly in the feces; only minute amounts were found in the urine and bile. Dihydromirex constituted 90-100% of the total radioactivity in tissues and feces. No metabolite was detected.
