NUMBER OF REPLICATIONS: Triplicates
Other: Plates not counted immediately were stored at 4°C. An automated colony counter was used for counting except when there was interference due to precipitation of test article and then manual counting was used. - Rationale for test conditions:
- Not specified
- Evaluation criteria:
- The revertants/ nmole were calculated by converting dose in Kg to nmole and taking the slope of the linear regression line of the dose-response curve. The logarithms of the slopes (revertants/ nmole) were used as activity parameters
- Statistics:
- Mean± Standard deviation was observed.

Applicant's summary and conclusion
- Conclusions:
- 3-Bromoquinoline (5332-24-1) was evaluated for its mutagenic potential in Salmonella typhimurium strains TA 98 and TA 100 by Ames test. The test result was considered to be negative with and without S9.
- Executive summary:
3-Bromoquinoline was assessed for its possible mutagenic potential. For this purpose AMES test was performed in Salmonella typhimurium strains TA 98 and TA 100. The test material was exposed at the concentration of 0, 6.7,10,33,67,100,333,667 and 1000 µg/plate in the presence and absence of S9. No mutagenic effects were observed. Only the data on TA100 with metabolic activation are reported here (Table) as the test substances tested on TA98 with and without S9 activation and on TA100without S9 activation were inactive. Therefore 3-Bromoquinoline was considered to be non mutagenic in presence and absence of S9.Hence the substance cannot be classified as gene mutant in vitro.
