title: Non-mutagenicity for Salmonella of the chlorinated hydrocarbons aroclor 1254, 1,2,4-trichlorobenzene, mirex and kepone.
abstract: A polychlorinated biphenyl mixture, Aroclor 1254, two commercial grade insecticides, mirex and kepone, and a pesticide breakdown product, 1,2,4-trichlorobenzene were evaluated for mutagenicity and hepatic enzyme induction potential in the Salmonella/microsomal assay. None was found to revert strains TA1535, TA1537, TA98 or TA100 when tested with or without metabolic activation. Liver microsomal extracts (S9) from rats induced with 1,2,4-trichlorobenzene were shown to differ from S9 of either control or Aroclor 1254-induced rats in the capacity to activate 2-aminoanthracene mutagenesis.
