Description of key information

One key study has been assessed as having determined the toxicity to algae. This study followed the OECD 201 guideline and was performed to GLP standards. 

Key value for chemical safety assessment

EC50/LC50 for freshwater algae:
64 mg/L
EC10, LC10 or NOEC for freshwater algae:
2.3 mg/L

Additional information

In this 96 h study, static freshwater conditions and test material concentrations of 10, 32, 100 and 1000 mg/l (measured) were used. The test material was found to affect the growth rate and biomass of pseudokirchneriella subcapitata. The ErC50 was found to be 64 mg/l, the EbC50 was 5.8 mg/l and the NOEC was 2.3 mg/l.
