- Additional information on results:
- The test material caused a visible reduction in the growth of the bacterial background lawn and/or a significant decrease in the frequency of revertant colonies in all of the bacterial tester strains both with and without metabolic activation. The first indication of toxicity was observed at 150 ug/plate.
All of the positive control chemicals used in the test induced marked increases in the frequency of revertant colonies thus confirming the activity of the S9-mix and the sensitivity of the bacterial strains.
Applicant's summary and conclusion
- Conclusions:
- Not mutagenic in the Salmonella typhimurium reverse mutation assay.
- Executive summary:
Introduction.
The method was designed to meet the requirements of the OECD Guidelines for Testing of Chemicals No. 471 “Reverse Mutation Study”, Method B 14 of Commission Directive 92/69/EEC and the USA, EPA (TSCA) OPPTS harmonised guidelines.
Methods.
Salmonella typhimurium strains TA1535, TA1537, TA98, TA100 and TA102 were treated with the test material using the Ames plate incorporation method up to seven dose levels, in triplicate, both with and without the addition of a rat liver homogenate metabolising system (10% liver S9 in standard co-factors). The dose range for the first experiment was determined in a preliminary toxicity assay and ranged between 1.5 to 5000 µg/plate depending on tester strain type. The experiment was repeated on a separate day using a similar dose range to Experiment 1, fresh cultures of the bacterial strains and fresh test material formulations.
Results.
The vehicle (dimethyl sulphoxide) control plates gave counts of revertant colonies within the normal range. All of the positive control chemicals used in the test induced marked increases in the frequency of revertant colonies, both with and without metabolic activation. Thus, the sensitivity of the assay and the efficacy of the S9-mix were validated.
The test material caused a visible reduction in the growth of the bacterial background lawn and/or a significant decrease in the frequency of revertant colonies in all of the bacterial tester strains both with and without metabolic activation. The first indication of toxicity was observed at 150 µg/plate. The test material was, therefore, tested up to either the maximum recommended dose of 5000 µg/plate or its toxic limit, depending on bacterial tester strain type and the presence or absence of S9-mix.
An oily precipitate was observed at 5000 µg/plate, this did not prevent the scoring of revertant colonies.
No significant increases in the frequency of revertant colonies were recorded for any of the bacterial strains, with any dose of the test material, either with or without metabolic activation.
Conclusion.
The test material was considered to be non-mutagenic under the conditions of this test.
