Description of key information

The NOEC for the algal toxicity is 0.19 mg/l ( limit of solubility), the EC50 is > 0.19 mg/l for all three endpoints.

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
0.19 mg/L

Additional information

The toxicity of Hydroxyambran in Algae was determined according to the OECD Test Guideline 201 resp.EC Test Guideline C.3.

No significant inhibition of algal growth was observed at the limit of solubility of the test item in the test medium (0.19 mg/l).

Therefore the NOEC for the algal toxicity is 0.19 mg/l, the EC50 is > 0.19 mg/l for all three endpoints.
