Bioavailability of lipophilic chemicals is influenced by the physicochemical properties of soils/sediment such as particle size, pH, clay, and organic carbon content. The present study investigated the effects of sediment composition and aging on the oral bioavailability of hexachlorobenzene (HCB) in rats. Formulated sediments were prepared using various(More)
This study determined the oral and dermal ADME of 2-amino-2-methyl-1-propanol (AMP), a substituted aliphatic alcohol used in a number of industrial and consumer products. Groups of 4 male Fischer 344 rats received either a single bolus oral or dermal dose of 18 mg/kg (14)C-AMP in water. The dermal dose was applied to an area of 12 cm(2) on the back of the(More)
Metabolism of diiodomethyl-p-tolylsulfone (DIMPTS) was investigated in rats to determine the role of iodide in its toxicity. Fischer 344 (F-344) (5 or 50mg/kg) or Sprague Dawley (SD) (5mg/kg) rats were gavaged with (14)C-DIMPTS or dermally applied with 5mg/kg (F-344 only) and absorption, distribution, metabolism and excretion (ADME) determined.
