Applicant's summary and conclusion
- Conclusions:
- Within an in vivo chromosome aberration test, sperm abnormalities were monitored and compared with the control.
The frequency of abnormal sperms did not differ significantly between treated and control mice at the P=0.05 level, indicating that diantimony trioxide did not exert a marked effect on testes even after prolonged treatment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
