Additional information

ccording to the CLP Regulation (EC) no. 1272/2008, Part 4: Environmental Hazards, substances can be classified for aquatic environment hazard when the following criteria are met:

(a) Short-term (acute) aquatic hazard

Category Acute 1: 96 h LC50(fish) and/or 48 h EC50(crustacea) and/or 72 or 96 h ErC50(algae or other aquatic plants) ≤ 1 mg/l.

(b) Long-term (chronic) aquatic hazard

(i) Non-rapidly degradable substances (Note 3) for which there are adequate chronic toxicity data available

Category Chronic 1: Chronic NOEC or ECx (for fish)0,1 mg/l and/or Chronic NOEC or ECx (for crustacea)0,1 mg/l and/or Chronic NOEC or ECx (for algae or other aquatic plants)0,1 mg/l.

Category Chronic 2: Chronic NOEC or ECx (for fish)1 mg/l and/or Chronic NOEC or ECx (for crustacea)1 mg/l and/or Chronic NOEC or ECx (for algae or other aquatic plants)1 mg/l.

The substance is not rapidly degradable and the available short-term and long-term toxicity tests to fish, aquatic invertebrate and algae fixed effect levels that do not meet these classification criteria.Therefore, the substance is not classified for aquatic toxicity according to the CLP Regulation (EC) no. 1272/2008.
