Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
other: mostly positive
16 in vitro tests suggest that the substance has genetic toxicity - Executive summary:
genetoxic:
In vitro, the substance reacts with DNA.
DNA damages are caused in various organisms, cells, and test systems e.g.
- Mutation is caused by the substance in bacteria and in plant cells.
- Mitotic recombination is caused by the substance in yeast.
- Chromosomal aberrations, sister chromatid exchanges and cell transformation are caused by the substance In cultured mammalian cells.
- DNA strand breaks are caused by the substance in vivo in rat brain cells.
