Conclusion on classification

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:

-Acute toxicity data:

The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is >> 1 mg/L (48-h EC50 > 100 mg/L; Daphnia magna; Harlan, 2012).

 Rationale:

Chronic data are available only for algae, therefore classification is based on the available chronic and acute toxicity data:

 - Chronic toxicity data:

Chronic data are only available for aquatic algae (not pH-adjusted, 72 -h ErC10 = 65 mg/L; Harlan, 2012). The substance is not rapidly degradable and the 72-h ErC10 > 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:

Daphnids and Fish are the trophic levels not covered by chronic data. Therefore, classification is based on the respective acute effect data. The lowest acute effect value is a 48-h LC50 of > 100 mg/L determined for Daphnia magna (not pH-adjusted, analytically verified); the substance is not rapidly degradable and the log Pow is < 4. According to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is not to be classified as chronically hazardous.
