Key Concepts

  • Chronic exposure to carbon tetrachloride (CCl4) - and sometimes acute exposure to very high concentrations - produces liver and kidney damage.
  • CCl4 is highly toxic. It is reasonably anticipated to be a human carcinogen, based on sufficient evidence of carcinogenicity from studies in experimental animals.
