Description of key information
Scientifically valid study shows limited inhibition of bactial growth at approximatley 50 mg/l equivalent of the hydroxide or chloride, with inhibition of specific bacterial strains starting at concentrations > 5 mg/l Cr III.
However, enhancement of growth at lower concentrations (essential element)
Citrate is assessed as biodegradable and is present in living tissues.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 50 mg/L
Additional information
Testing performed on other Cr III salts.
