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 not officially classified.

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not officially classified.

 

Self-classification

Aquatic compartment

Following GHS, the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available acute and chronic 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 (72-h ErC50 for marine algae: 9 mg/L).

Chronic data are available for two trophic levels, Daphnids and algae; therefore, the classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available aquatic invertebrates (21-d EC10: 8.134 mg/L) and for freshwater algae (96-h NOErC = 10 mg/L), indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances.

- Acute toxicity data:

Fish is the trophic level not covered by chronic data. Therefore, the asessment is based on the respective available acute toxicity data. Acute toxicity to fish is >>1 mg/L (96h LC50 for fish: 180 mg/L). The substance is rapidly biodegradable (freshwater); the measured BCF is < 500. 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 to the aquatic environment.

- Conclusion: The substance is not to be classified as chronically hazardous to the aquatic environment.

 

Atmospheric compartment
