Additional information
Conclusion on classification
Fish acute data: 96h-LC50: 30.66 mg/L (measured);
Daphnia acute data: 48h-EC50: > 24.2 mg/L (measured);
Algae growth inhibition data:
Acute data: 72h-ErC50 value (growth rate): > 28.9 mg/L (measured);
Chronic data: NOEC: >28.9 mg/L (measured)
And the substance is considered to be readily degradable and log Pow was -0.24.
Acute classification:
In according to Regulation (EC) 1272/2008, amendment 286/2011, table 4.1.0 (a), acute classification is either Category Acute 1 or not classified, Category Acute 1 applies if EC50 for fish or Daphnia magna or algae ≤ 1 mg/L.
For this substance all EC50 values are > 1mg/L, therefore the substance is not classified for acute aquatic toxicity.
Chronic classification:
In according to Regulation (EC) 1272/2008, amendment 286/2011, table 4.1.0 (b.ii), rapidly degradable substances for which adequate chronic toxicity data available, chronic classification is either Category Chronic 1, Category Chronic 2, Category Chronic 3 or not classified.
As the substance is considered to be readily degradable, actual NOEC value for Algae > 1 mg/L, Category Chronic 1, 2 and 3 do not apply (Category Chronic 3 is required for rapidly degradable substances if chronic NOEC or ECx for fish or Daphnia magna or algae > 0.1 to ≤ 1 mg/L).
Therefore the substance is not classified for chronic aquatic toxicity.
