Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Algae were exposed to 0 and 100 mg/L test substance during 72 hours. No effects on growth rate and biomass were found. The analyses for accuracy of preparation at the maximum concentration attainable showed that the average measured concentration at a loading rate of 100 mg/L was 0.020 mg/L. The ECr50 for algae is > 100 mg/L as loading rate and the NOEC is 100 mg/L as loading rate (Harlan 2012f).

Key value for chemical safety assessment

EC50 for freshwater algae:
0.02 mg/L
EC10 or NOEC for freshwater algae:
0.02 mg/L

Additional information

The analogue of the test substance did not show any effects at a loading rate of 100 mg/L (Chemservice 2010d), which is in line with the results mentioned above.
