exposure of male rats to the polychlorinated terphenyl ( pct ) mixtures aroclor 5460 and aroclor 5432 containing 60 % and 32 % ( w/w ) of chlorine , respectively , showed that the pct mixture with a low degree of chlorination , aroclor 5432 , was a potent inducer of liver microsomal cytochrome p-450 , aryl hydrocarbon hydroxylase ( ahh ) and 7-ethoxyresorufin o-deethylase whereas aroclor 5460 and the unchlorinated isomers o- , m- and p-terphenyl were weak inducers .
