| Abstract | Characterization of the pharmacokinetics of volatile organic compounds (VOCs) requires reliable analytical techniques for measuring tissue concentrations. An extraction procedure was developed which minimized loss of the readily volatilizable compounds, so that they could be quantified by headspace gas chromatography. The procedure was evaluated using four C2 halocarbons (i.e., perchloroethylene (PER), 1,1,1-trichloroethane (TRI), 1,2,2,2-tetrachloroethane (TET), and 1,1,2-trichloroethylene (TCE) of varying physicochemical properties. Percent recoveries of each of the four halocarbons ranged from 73%-104% for the seven spiked tissues. The recoveries did not appear to be tissue-dependent, but did vary somewhat with test chemical, with the least volatile, most lipophilic compounds exhibiting the highest recovery. |
