Method
Species / strain
- Species / strain / cell type:
- S. typhimurium TA 1535, TA 1537, TA 98 and TA 100
- Details on mammalian cell type (if applicable):
- Ecoli WP2uvrA was also evaluated in the study (with and without activation)
- Metabolic activation:
- with and without
- Metabolic activation system:
- Phenobarbital and 5,6-benzoflavone-induced rat liver homogenate (S9-mix).
- Test concentrations with justification for top dose:
- 0.05, 0.1, 0.5, 1, 5 ,10 ,and 50% in the atmosphere
Controls
- Untreated negative controls:
- yes
- Negative solvent / vehicle controls:
- no
- True negative controls:
- yes
- Remarks:
- sham exposed bacteria
- Positive controls:
- yes
- Positive control substance:
- other: AF-2, NaN3, 9AA as appropriate
- Details on test system and experimental conditions:
- - Exposure duration to test substance in gas exposure chamber followed by 24 - 48 hour exposure to test substance at 37°C
- Evaluation criteria:
- Study is considered valid if the mean colony counts of the control values of the strains are within acceptable ranges, if the results of the positive controls meet the criteria for a positive response, and if no more than 5 % of the plates are lost through contamination or other unforeseen events.
A test substance is considered to be positive in the bacterial gene mutation test if the mean number of revertant colonies on the test plates is concentration-related increased or if a two-fold or more increase is observed compared to that on the negative control plates.
A test substance is considered to be negative in the bacterial gene mutation test if it produces neither a dose-related increase in the mean number of revertant colonies nor a positive response at any of the test points. - Statistics:
- None
