Key value for chemical safety assessment

EC50 for freshwater algae:
0.705 mg/L
EC50 for marine water algae:
0.188 mg/L

Additional information

In an algal growth inhibition test according to OECD 201 in the presence of humic acid the EC50-value (72h) of the test substance on Pseudokirchnerella subcapitata was determined to be 0.705 mg/L. The NOEC was determined to be 0.188 mg/L (BASF SE 2015).
