Additional information
Conclusion on classification
Official classification regarding environmental hazards
Aquatic compartment
In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is officially classified as "Aquatic Chronic 2".
In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is officially classified as "N; R51 -53".
Self-classification
Following CLP (GHS-EU), the substance is not to be classified as acutely or chronically hazardous to the aquatic environment. However, the substance is officially classified as Aquatic Chronic 2.
Rationale:
The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
Chronic data are available for all three trophic levels (fish, aquatic invertebrates and algae), therefore classification is based on the available chronic toxicity data:
- Chronic toxicity data:
The substance is non-rapidly degradable and the lowest NOEC/EC10is > 1 mg/L. According to the criteria outlined in Table 4.1.0(b) (i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
