Description of key information

An E[r]C50 of 0.51 mg/L was determined and a NOEC[r] of 0.013 mg/L was calculated after 72 hrs. All results are expressed in terms of geometric mean measured concentrations. Effective concentrations ranged from 1.2 % to 5.7 % of nominal values at 72 hours.

Key value for chemical safety assessment

EC50 for freshwater algae:
0.51 mg/L
EC10 or NOEC for freshwater algae:
0.046 mg/L

Additional information

Effective concentrations ranged from 5.5 % to 6.0 % of nominal values at 0 hours, from 4.4 % to 6.1 % of nominal values at 24 hours and from 1.5 % to 5.8 % of nominal values and at 48 hours.
