Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not classified as hazardous to the environment.

According to Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not classified as hazardous to the environment.

Self-classification

Aquatic compartment

Following GHS, the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available chronic and acute data, the substance is not to be classified as chronically hazardous to the aquatic environment.

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 aquatic invertebrates and algae. Therefore, classification is based on the available chronic and acute toxicity data.

 

- Chronic toxicity data: Chronic data are available for aquatic invertebrates (21 -d NOEC =10 mg/L) and algae (72 -h ErC10 > 100 mg/L). The substance is not rapidly degradable and the NOEC/EC10 is > 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.

 

- Acute toxicity data: Fish is the trophic level not covered by chronic data. Therefore, classification is based on the respective acute effect data. The LC50 is > 100 mg/L, the substance is not rapidly degradable and the log Pow is > 4, but the substance is only poorly soluble in water (< 0.002 mg/L). Therefore, the substance is not to be classified as chronically hazardous to the aquatic environment.
