Conclusion on classification
Data on short-term ecotoxicity are available on the substance.
Chronic data are available and the substance is non ready biodegradable.
a) Acute (short-term) aquatic hazard
Category Acute 1:
< 1 mg/L and/or 96 hr LC50 (for fish)
< 1 mg/L and/or 48 hr EC50 (for crustacea)
< 1 mg/L 72 or 96 hr ErC50 (for algae or other aquatic plants)
b) Long-term aquatic hazard
(i) Non-rapidly degradable substances for which there are adequate chronic toxicity data available Category Chronic 1:
< 0,1 mg/L and/or Chronic NOEC or ECx (for fish)
< 0,1 mg/L and/or Chronic NOEC or ECx (for crustacea)
< 0,1 mg/L Chronic NOEC or ECx (for algae or other aquatic plants)
Category Chronic 2:
< 1 mg/L and/or Chronic NOEC or ECx (for fish)
< 1 mg/L and/or Chronic NOEC or ECx (for crustacea)
< 1 mg/L Chronic NOEC or ECx (for algae or other aquatic plants)
According to CLP Regulation 1272/2008, when non-rapidly degradable substances for which there are adequate chronic toxicity data available:
The short-term ecotoxicity values are available for three throphic level:
LC50 (96 h) fish: 4.62 mg/L
EC50 (48h) invertebrate Daphnia: 17 mg/L
EbC50 (72h) aquatic plants: 13 mg/L
NOEC (48h) invertebrate Daphnia: 3.9 mg/L
NOEbC (72h) algae: 0.44 mg/L
The acute aquatic toxicity based on the lowest of the available toxicity values is between 1 and 10 mg/L (fish 4.62 mg/L).
Adequate long-term toxicity data available only for crustacenas and algae. The chronic aquatic toxicity (based on the lowest of the two available toxicity values) is above 1 mg/L (NOEbC 0.44 mg/L).
As conclusion, according to the classification criteria of the CLP regulation n. 1272/2008, the registered substance is classified for the environment as H411, Category Chronic 2.
