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.
