Description of key information

The 48-Hour EL50 was determined to be 23 mg/L nominal loading rate and the No Observed Effect Loading rate was 10 mg/l nominal loading rate by read across to data from an analog substance.

Key value for chemical safety assessment

Additional information

Since tests on toxicity of the UVCB substance itself to aquatic invertebrates are not available, a conclusion by analogy approach according to Annex XI of REACH has been applied.

 

The acute toxicity of an analog of this substance, EC 283-392-8, was evaluated in Daphnia (Goodband, TJ, 2005; OECD Guideline 202). The 48-Hour EL50 was determined to be 23 mg/L nominal loading rate and the No Observed Effect Loading rate was 10 mg/l nominal loading rate.
