Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Effect conc.:
> 50 - < 74 µg/L
Nominal / measured:

Conc. based on:
dissolved
Basis for effect:

Details on results:
There were no toxic effects up to 250μg Cd/L and there was 70% mortality at 750μg Cd/L)

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
Studies on various test species using cadmium metal and cadmium oxide resulted in LC50 values ranging from 5 to 74,000 ug/L. Because of the similarity of the candidate substance of this application to cadmium oxide, it is expected that the candidate substance of this application behaves similarly to cadmium oxide.
