Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The EC50 based on growth for aquatic algae is 1.02 mg/L based on nominal test concentrations.

The observed EC10 based on growth is 69 µg/L based on nominal test concentrations

Key value for chemical safety assessment

EC50 for freshwater algae:
1.02 mg/L
EC10 or NOEC for freshwater algae:
69 µg/L

Additional information

The EC50 for aquatic algae is 1.02 mg/L based on nominal initial test concentrations. The test was performed in natural river water.

The exposure concentrations were monitored but as the bulk-approach is applied and no sorption to glassware or (bio)degradation is considered to take place the algae were fully exposued to the nominal test substance concentrations during the test.
