Description of key information
With high probability acutely not harmful to aquatic algae.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 500 mg/L
Additional information
In a 96-h GLP static algal toxicity study, the 72-h NOEC (growth rate) was determined to be 500 mg/L (Hoechst Celanese, 1990; statistical re-evaluation: ECT, 2010). The 72-h ErC20 was 807 mg/L and the 72 -h ErC50 was > 1000 mg/L. Test item concentrations were analytically verified.
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.
