Conclusion on classification

Environmental classification justification

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 CLP (GHS-EU), 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 to be classified as chronically hazardous to the aquatic environment (category chronic 3).

 

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, therefore classification is based on the available chronic and acute toxicity data.:

- Chronic toxicity data:

Chronic toxicity data are available for algae (72-h NOErC = 57.8 mg/L; BASF SE, 2012). According to the criteria 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) the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data:

The lowest acute effect value is 17 mg/L (fish: 96h LC50 = 17 mg/L; Saltigo GmbH, 1984). The substance is not rapidly degradable; the log Kow is < 4 (Log Kow = 2.1; at 24°C; BASF AG, 1999). The substance is to be classified as chronically hazardous to the aquatic environment (category chronic 3) based on the categories outlined in Table 4.10(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/008.

 

Atmospheric compartment

The test substance is not listed in Annex 1 of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.

The test substance does not belong to the green-house gases listed in P Forster, PV Ramaswamy et al. Changes in Atmospheric Constituents and Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Goup 1 to the Fourth Assessment Report of the Intergovernmental Panel on climate Change.
