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 or 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 values are greater than 1 mg/L (aquatic algae: 72 -h ErC50 = 16.4 mg/L; read-across data from CAS 3886-69-9).

Chronic data are available only for algae (72-h ErC10 = 4.7 mg/L; read-across to CAS 3886-69-9). Therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The substance is rapidly degradable and the ErC10 is greater than 1 mg/L. According to the criteria outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances, the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data: Fish and Daphnia are the trophic levels not covered by chronic data. Therefore classification is based on the respective acute effect data. The lowest LC/EC50 is between 10 and ≤ 100 mg/L (Daphnia, 48-h EC50 = 18.2 mg/L; read-across data from CAS 2627-86-3). The substance is rapidly degradable and the log Pow is < 4. The substance is not to be classified as chronically hazardous to the aquatic environment.

  

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. In: Climate Change 2007: The Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change.
