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.

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 value is > 1 mg/L.

Chronic data are available only for algae, but not for fish and daphnids. Therefore classification is based on the available chronic and acute toxicity data.

 

- Chronic toxicity data:

Chronic data are available for algae (72-h NOErC= 62.5 mg/L).

The substance is rapidly degradable and the 72h-NOErC is > 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) the substance is not to be classified based on the available chronic data.

 

- Acute toxicity data:

Fish and daphnids are the trophic levels not covered by chronic data. Therefore classification is based on the respective acute effect data.

The 96-h LC50 for fish is 460 mg/L; for daphnids, the 48-h EC50 is > 500 mg/L. Moreover, the substance is rapidly degradable. Therefore the substance is not to be classified as chronically hazardous based on acute toxicity data.

 

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.
