Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2, the substance holds no relevant classification.

 

Self-classification

Aquatic compartment

Following CLP, the substance is not to be classified as acutely hazardous for the aquatic environment. Based on the available chronic data, the substance is to be classified as chronically hazardous to the aquatic environment (chronic 2).

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 (48h-EC50 = 6.94 mg/L, Danish EPA 2000, report no. 81089/270).

Chronic data are available for algae and invertebrates, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available for algae (72h ErC10 = 13.5 mg/L, BASF SE 2012, report no. 60E0487/11E118) and invertebrates (Daphnia magna reproduction: 21d EC10 = 0.86 mg/L; BASF SE 2013, report no. 51E0487/11E119). 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 to be classified as chronically hazardous (Chronic 2) to the aquatic environment

- Acute toxicity data:

Fish is the trophic level which is not covered by chronic data. Therefore, classification is based on the respective acute effect data. For fish, the 96h-LC50 is determined to be > 100 mg/L (BASF SE 1987, report no. 10F0181/875068). The substance is not rapidly degradable; 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.

- Conclusion: Based on the available chronic toxicity data, the substance is to be classified as chronically hazardous to the aquatic environment (Chronic 2).
