Almost the entire production of the compound is consumed in manufacturing chlorinated solvents, especially trichloroethylene and tetrachloroethylene; it has minor uses as a solvent and as an insecticide, particularly against the greenhouse white fly. CCl4 can induce embryotoxic and embryo lethal effects, but only at doses that are toxic to the mother, as observed in the inhalation studies in rats and mice. Liver damage occurs more often from swallowing liquid CCl4 than from inhaling CCl4 vapor [Hathaway et al. 32F. The other isomer, 1,1,1,2-tetrachloroethane, has no commercial application. Effects have been investigated on different systems on both humans and animals, stated respectively. 1991].
