Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2, the substance is not classified regarding environmental hazards. 

 

Self-classification

Aquatic compartment

Following CLP, 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 (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 data are available only for algae (72-h ErC10 = 37 mg/L, BASF SE 2013, report no. 60E0241/13X030). According to the criteria outlined in Table 4.1.0(b) (i) (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.

- Acute toxicity data:

Fish and aquatic invertebrates are the trophic levels which are not covered by chronic data. Therefore, classification is based on the respective acute effect data for fish (96-h LC50 = 53.1 mg/L; calculated data (worst-case approach); model: ECOSAR v1.11, within applicability domain) and Daphnids (48-h EC50 = 51.9 mg/L; BASF AG 2005). The lowest acute data available is the 48-h EC50 of 51.9 mg/L determined for aquatic invertebrates; 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 to be classified as chronically hazardous to the aquatic environment (Category Chronic 3).

- Conclusion: The substance is to be classified as chronically hazardous to the aquatic environment (Chronic 3).
