Carbon disulfide. I. The metabolism of inhaled carbon disulfide in the rat. 1977

M J McKenna, and V DiStefano

The pharmacokinetics of inhaled carbon disulfide (CS2) vapor was evaluated in rats. Estimates of free CS2 and its nonvolatile, acid-labile metabolites (AL CS2) were made in a variety of rat tissues after an 8-hour inhalation exposure to CS2 vapor (2 mg/l of air). At the end of the exposure, all tissues examined contained appreciable amounts of the native solvent and AL CS2. Elimination of CS2 from the rat during the postexposure period was rapid and occurred primarily via the lungs. Excretion of AL CL2 occurred primarily via the kidneys and was prolonged with respect to that of free CS2. Accumulation of these metabolites upon repeated exposures and their presence in all tissues examined suggest that they may play a role in the toxicity of CS2.

D008297 Male Males
D002246 Carbon Disulfide A colorless, flammable, poisonous liquid, CS2. It is used as a solvent, and is a counterirritant and has local anesthetic properties but is not used as such. It is highly toxic with pronounced CNS, hematologic, and dermatologic effects. Disulfide, Carbon
D005740 Gases The vapor state of matter; nonelastic fluids in which the molecules are in free movement and their mean positions far apart. Gases tend to expand indefinitely, to diffuse and mix readily with other gases, to have definite relations of volume, temperature, and pressure, and to condense or liquefy at low temperatures or under sufficient pressure. (Grant & Hackh's Chemical Dictionary, 5th ed)
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
