Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

In an early lifestage study in fish, the headline NOAEC of 150 ug/l is based on survival and vigour, but statistically uncertain reductions in length and weight occurred at 45 and 89 ug/l

Chromium III is available in natural waters and is an essential element. The metal therefore goes through biotrasformation processes and is no accumulative.

Based on these charcteristics, classification as Aquatic Chronic 3 is proposed.
