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 DSD/DPD, the substance is to be classified as dangerous for the aquatic environment (N, R51/53).

Rationale: The lowest acute toxicity to aquatic organisms (LC/EC50) is between 1 and 10 mg/L and the substance is not readily biodegradable.

 

Following GHS, the substance is not to be classified as acutely and 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 Daphnia and algae, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: Chronic data are available for Daphnia (NOEC = 4.0 mg/L) and algae (ErC10 > 100 mg/L). Moreover the ACR approach according to ECETOC No. 91 (2003) for fish results in a chronic NOEC greater than 1 mg/L. In conclusion these data indicate that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for non-rapidly degradable substances.

- Acute toxicity data: Fish is the only trophic level not covered by chronic data, therefore classification is based on the acute effect data. The LC50 is > 100 mg/L (neutralised) and the substance is non-rapidly degradable. The log Kow is <4. Therefore the substance is not to classified as chronically hazardous.

 

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.
