Description of key information

72h EL50 ( growth rate and biomass) is > 1000 mg/L loading rate WAF. The 72 hour No Observed Effect loading rate was 1000 mg/L loading rate WAF. 

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L

Additional information

The acute toxicity was evaluated in freshwater algae in accordance with OECD Guideline 201. Exposure of Scenedesmus subspicatus to the test material gave an EL50 (72h,growth rate and biomass) of > 1000 mg/L WAF. The 72 hour No Observed Effect loading rate was 1000 mg/L loading rate WAF.
