Description of key information
Short-term toxicity to fish
In an acute toxicity test similar to OECD Guideline 203 with the structural analogue chromium trichloride (CAS 10025 -73 -7), the 96-h LC50 was determined to be 11.2 mg/L (nominal).
Short-term toxicity to aquatic invertebrates
The 72-h EC50 (growth rate) of the structural analogue chromium trichloride (CAS 10025-73-7) was determined to be 111 mg/L.
Toxicity to aquatic algae
The 96-h NOEC and EC50 of the structural analogue chromium trichloride (CAS 10025-73-7) was determined to be 0.08 mg/L and 397 µg//L (nominal, based on chromium(III)).
Remark: The toxicity of the registration substance to fish, aquatic invertebrates and aquatic algae was assessed in read across approach with the structural analogues Methacrylic acid (CAS 79-41-4), Chromium trichloride (CAS 10025-73-7) and Propan-2-ol (CAS 67-63-0). Based on worst case assumption, effect concentrations of the registration substance were derived from results for chromium trichloride.
Toxicity to microorganisms
The 3-h EC10 and EC50 values of test item were determined as higher than 1000 mg/L. The NOEC was 1000 mg/L.
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
