Mutagenesis of mammalian cells in culture by chlorophenols,chlorocatechols and chloroguaiacols

The mutagenicity of 4 chlorinated phenols, 4 chlorinated catechols, 3 chlorinated guaiacols, one chloromethoxyphenol and one wood preservative mixture was studied in a mammalian cell assay, in which Chinese hamster cells V79 are used. Of the compounds studied 2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol, 3,4,6-trichlorocatechol, 4,5,6-trichloroguaiacol and the wood preservative were mutagenic in the test system used.
