Species / strainopen allclose all
- Species / strain / cell type:
- S. typhimurium TA 97
- Details on mammalian cell type (if applicable):
- Not applicable
- Additional strain / cell type characteristics:
- not specified
- Species / strain / cell type:
- S. typhimurium TA 98
- Details on mammalian cell type (if applicable):
- Not applicable

- not specified
- Metabolic activation:
- with and without
- Metabolic activation system:
- Aroclor-induced hamster and rat liver S9
- Test concentrations with justification for top dose:
- The highest dose was 1750 µg/plate as the limiting factor was that hydrogen sulphide gas was limited by its solubility in ethanol, which was the test solvent.
- Vehicle / solvent:
- Ethanol

- not specified
- True negative controls:
- not specified
- Positive controls:
- not specified
- Details on test system and experimental conditions:
- Salmonella typhimurium TA97, TA98 and TA100 strains, either with or without S9 liver fraction of male rats or hamsters that had been induced with 500 mg/kg Arcoclor.
