Description of key information

Key value for chemical safety assessment

EC50/LC50 for freshwater algae:
97.9 mg/L
EC10, LC10 or NOEC for freshwater algae:
30.64 mg/L

Additional information

Basing on a test performed according to OECD TG 201 on the similar substance ursodeoxycholic acid, the EC50values at 72 hours, calculated in terms of nominal active ingredient concentration, were> 97.90 mg/L for growth rate and > 97.90 mg/L for biomass loss. The NOEC values, instead, were 97.90 mg/L for growth rate and 30.64 mg/L for biomass loss, respectively.
