title: The disposition and metabolism of tetrabromobisphenol-A after a single i.p. dose in the rat.
abstract: Tetrabromobisphenol-A (TBBP-A) is used as a reactive (primary use) or an additive flame retardant and as an intermediate in the production of other flame retardants. In our study TBBP-A[14C] was administered intraperitoneally (i.p.) in a single dose of 250 or 1000 mg/kg body weight (about 300 kBq per animal). The level of radioactivity in erythrocytes was 10 times higher than in plasma 72 h after the administration. In all examined tissues the peak level of 14C could be observed within the first hour after the administration, and the highest concentrations were detected in the fat tissue, followed by liver, sciatic nerve, muscles and adrenals. Total excretion in faeces 72 h after the administration was about 51-65% of the dose, whereas in urine it was only 0.3%. About 20% was still retained in the rat organism.
