Description of key information

The substance was not toxic to algae when tested according to OECD guideline 201 (Alga, Growth Inhibition Test), with a 72-hour EC50 value greater than 100 mg/L
EC50 (Algae, 72 hr, OECD 201): > 100 mg/L
NOEC (Algae, 72 h, OECD 201): 9.77 mg/L
LOEC (Algae, 72 h, OECD 201): 31.3 mg/L

Key value for chemical safety assessment

Additional information

Statistically significant differences to the control were determined at 31.3 and 100 mg/L. No EC50-values were determined due to the fact that the inhibitory effects were below 50%. Therefore the EC50-value for growth rate and yield was estimated to be > 100mg/L. The LOEC is estimated to be 31.3 mg/L, the NOAEC was determined to be 9.77 mg/L.
