- Additional information on results:
- 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.
Any other information on results incl. tables
The test material caused no visible reduction in the growth of the bacterial background lawn at any dose level. The test material, therefore, tested up to the maximum recommended dose level of 5000µg/plate. A precipitate was observed at 5000µg/plate, this did not prevent the scoring of revertant colonies.
A dose-related, reproducible and statistically significant increase in revertant colony frequency was observed to several of the tester strains (both with and without metabolic acivation) with doses of the test material beginning at 150µg/plate.
The mutagenic responses were predominantly observed to those tester strains sensitive to base-pair substitution in the genetic material.
The test material was, therefore, considered to be mutagenic under the conditions of this test.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
positive
The test material, EP-4000S, was considered to be mutagenic under the conditons of this test.
