Establishment of a new experimental approach for direct exposure of bacteria with actual generated smoke aerosol. This allowed us to investigate the mutagenic activity of native mainstream smoke on Salmonella Typhimurium strains. The new procedure of exposing bacteria directly to gases and complex mixtures offers new possibilities in the field of inhalation genotoxicology for the evaluation of genotoxicity in the Ames assay.
