Abstract
The mutagenicity of SRM 1649 and 1650 was tested in the presence of rat liver S9 mix which was induced by polychlorinated biphenyl (PCB) or by the combination of phenobarbital and 5,6-benzoflavone. The S9 mix induced by PCB activated benzo[ a]pyrene strongly. The S9 mix induced by phenobarbital-5,6-benzoflavone activated the complex mixtures to approximately the same extent as that induced by PCB. This finding indicates that phenobarbital-5,6-benzoflavone instead of PCB may be suitable as an inducer under some conditions. The preincubation procedure for the mutagenicity test was performed by preincubating the test compound, S9 mix and bacteria for 20 min in a water bath. This procedure was as effective as the plate incorporation test.
