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 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 (fish: 96-h LC50 >100 mg/L; Daphnids: 48-h EC50 >100 mg/L) are greater than 1 mg/L.

 

Chronic data are not available. Therefore, classification is solely based on the available acute toxicity data.

- The classification is based on the respective acute effect data available (fish: 96-h LC50 >100 mg/L, BASF SE, 2017; daphnids: EC50 >100 mg/L, BASF SE, 2017; aquatic plants: 7-d ErL50 > 320 mg/L, BASF SE, 2017). The substance is not 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.
