PG - 357-66 AB - The disposition kinetics of tri-(2-ethylhexyl)trimellitate (TEHTM), a new plasticizer for polyvinyl chloride (PVC) plastic, was studied in rats following intravenous administration of [14C-carbonyl]tri-(2-ethylhexyl)trimellitate using an oil in water emulsion as the vehicle. The distribution half-life, elimination half-life, and clearance values estimated from the plasma concentration of radioactivity data obtained following iv administration of 10.5 mg/kg of TEHTM (59.9 muCi/kg), were 46.2 min, 5.34 d, and 40.5 ml/kg X h, respectively. Following iv dosage of 15.6 mg/kg of TEHTM (28.0 muCi/kg), significant accumulation of radioactivity was found in the liver, lungs, and spleen, with liver accounting for 72% of the administered dosage at 24 h. Excretion of TEHTM and its biotransformation products was slow, with 21.3% of the administered radioactivity found in the feces and 2.8% in the urine during the 14-d collection period. Biliary excretion seems to be the major route of elimination of TEHTM. The pharmacokinetic data gathered in the present investigation are compared to di-(2-ethylhexyl)phthalate (DEHP), a widely used plasticizer for PVC.
