Description of key information
Acutely harmful to aquatic plants
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 19.2 mg/L
- EC10 or NOEC for freshwater algae:
- 3.46 mg/L
Additional information
Acute toxicity to algae was investigated in a static GLP test according to OECD guideline 201 using Pseudokirchneriella subcapitata as test organism (BASF 2012). After 72 hours an EC50 of 19.2 mg/L and a NOEC of 3.46 mg/L were estimated based on the endpoint growth rate and the mean analytically determined concentrations.
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).
