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.
