Description of key information

The concentration causing 50% inhibition of the growth rate of Pseudokirchneriella subcapitata, i.e. the ErC50/72 h value is higher than 10.0 mg/L. The ErC20/72 h value is 1.26 mg/L, whereas the ErC10/72 h value is 0.42 mg/L. For the growth rate, the LOEC/72 h is 0.30 mg/L, whereas the NOEC/72 h is 0.09 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
10 mg/L
EC10 or NOEC for freshwater algae:
0.09 mg/L
