Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
genetic toxicity in vitro
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Values are predicted from model. Thus, they provide an approximation compared to experimental measure.

Additional information on results:
Mutagenicity by Kazius et al. (1=active; 0= inactive): 0 - mismatch of chemical domains
Mutagenicity by Benigni et al. (1=active; 0= inactive): 0
Micronucleus assay by Benigni et al. (1=active; 0= inactive): 0

Applicant's summary and conclusion

Conclusions:
There are no structural alerts that yttrium chromite might has mutagenic potential.
Executive summary:

We tested for structural alerts that indicate mutagenic potential of yttrium chromite, using ChemProp. For Mutagenicity the models by Kazius et al. and by Benigni et al. were used and additionally we applied the model: Micronucleus assay by Benigni et al. All models indicate that there are no structural alerts that yttrium chromite might has mutagenic potential.
