Additional information

Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2 there is no information on the substance available yet.

 

Self-classification

Aquatic compartment

Following DSD/DPD, the substance is to be classified as dangerous for the environment (R 52/53).

Rationale:

- The lowest acute toxicity to aquatic organisms (LC/EC50) is between10 and 100 mg/L in freshwater.

- The substance is not readily biodegradable (freshwater) but the log Pow is <3.

 

Following GHS, the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available acute data, the substance is to be classified as chronically hazardous to the aquatic environment (chronic 3).

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 not available, therefore classification is based on the available acute toxicity data.

- Chronic toxicity data:

Chronic data are not available.

- Acute toxicity data:

Acute toxicity to aquatic organisms (LC/EC50) is between 10 and 100 mg/L in freshwater (96h EC50 algae: 16 mg/L) indicating that the substance presents a long-term hazard according to the categories outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for non-rapidly degradable substances without adequate chronic toxicity data.

The substance is not rapidly biodegradable but the log Kow is <4. In conclusion, the substance has to be classified as category Chronic 3.

Atmospheric compartment

The test substance is not in Annex I of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.

The test substance does not belong to the greenhouse gases listed in P Forster, PV Ramaswamy et al. Changes in Atmospheric Constituents and in Radiative Forcing.
