Additional information

Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

No data were found for the substance concerning Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2.

 

Self-classification

Aquatic compartment

Following DSD/DPD, the substance is not to be classified as dangerous for the environment.

Rationale:

- The lowest effect value for acute toxicity to aquatic organisms (LC/EC50) is higher than 1 mg/L.

- The substance is readily biodegradable and the log Pow is <3.

 

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 for daphnia and algae; therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available for algae (8 -d ErC3 = 1.6 mg a.i./L) and Ceriodaphnia (7d NOEC: 3.2 mg a.i./L) indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances. Based on the chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment as the lowest NOEC is >1.

- Acute toxicity data:

Acute toxicity data: Fish is the trophic level not covered by chronic data. Therefore, classification is based on the respective acute effect data. The LC50 is > 100 mg/L (nominal, weigh-of-evidence, see h. 6.1.1). The substance is rapidly biodegradable and the log Kow is <4. Based on the acute data, 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.
