| Abstract |
There has been an increasing need in genetic toxicology to progress from strictly qualitative tests to more quantitative tests. This, in turn, has increased the need to develop better quality assurance and comparative bioassay methods. In the paper, two laboratories tested 10 Salmonella mutagens in order to determine the usefulness of selected chemicals as potential reference materials to calibrate the Salmonella assay. If variance within a bioassay is sufficiently low and the rankings of the compounds are of acceptable consistency, the chemicals later could be evaluated for use as standard control compounds, as audit materials, and as standard reference materials for comparative bioassay efforts. The results demonstrated that the chosen chemicals (with the possible exception of dimethylcarbamylchloride) provide such consistent results in the Salmonella mutagenicity bioassay that they can be used for semi-quantitative calibration and as possible bioassay controls, special audit chemicals, and potentially as reference standards in comparative bioassay efforts.
