Description of key information
The acute toxicity in fresh water algae was evaluated for an analog of this substance, EC 283-392-8 and ErL50 (0-72hr) value of 24 mg/L loading rate WAF was obtained. Therefore, the test substance is expected to be acutely not harmful to algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 24 mg/L
Additional information
Since tests on toxicity of the UVCB substance itself to aquatic algae 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 freshwater algae in accordance with OECD Guideline 201 (Vryenhoef, H, 2005). Exposure of Scenedesmus subspicatus to the test material gave an EbL50 (72h) value of 21 mg/L loading rate WAF and an ErL50 (0-72hr) value of 24 mg/L loading rate WAF. The No Observed Effect Loading rate was 10 mg/L loading rate WAF.
