Any other information on results incl. tables
The test compound did not cause a significant increase in the number of revertant colonies with any of the tester strains neither in the absence nor presence of S9-mix. It is concluded that the test substance is not mutagenic in this bacterial test system neither in the absence nor in the presence of metabolic activation.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
The test compound did not cause a significant increase in the number of revertant colonies with any of the tester strains neither in the absence nor presence of S9-mix. It is concluded that the test substance is not mutagenic in this bacterial test system neither in the absence nor in the presence of metabolic activation. - Executive summary:
The test substance methyl chloroacetate was tested for mutagenicity with the strains TA98, TA100, TA1535, TA1537 and TA1538 of Salmonella typhimurium and WP2uvrA of E.coli. The mutagenicity studies were performed in the absence and in the presence of metabolic activation. A dose range of six concentrations from 4 µg/plate to 5000 µg/plate was used. Control plates and positive controls were also included in the study. The test compound did not cause a significant increase in the number of revertant colonies with any of the tester strains neither in the absence nor presence of S9-mix. It is concluded that the test substance is not mutagenic in this bacterial test system neither in the absence nor in the presence of metabolic activation.
