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 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 values available (algae: 72 -h ErC50 = 34 mg/L; read-across data from CAS# 104-78-9) are greater than 1 mg/L.

Chronic data are available for algae (72-h ErC10 = 26 mg/L) and aquatic invertebrates (22-d NOEC = 3.64 mg/L). Therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The substance is rapidly degradable and the lowest chronic value available (daphnids: 22-d NOEC = 3.64 mg/L) 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 is the trophic level not covered by chronic data. Therefore classification is based on the respective acute effect data; the 96-h LC/EC50 for fish is 122 mg/L. The substance is 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 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.
