Conclusion on classification

Official classification regarding environmental hazards:

Aquatic compartment

The Commission Working Group on the Classification and Labelling of Dangerous Substances: Environmental Effects agreed that the substance should not be classified for dangers to the environment. (Reference: SUMMARY RECORD Commission Working Group on the Classification and Labelling of Dangerous Substances: Environmental Effects, ECBI/48/97 - Rev. 1., Belgirate, 10-12 September 1997;http://apps.kemi.se/nclass/Tempresults.asp)

In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.1 or Table 3.2: The substance holds no relevant classification.

Self-classification:

Aquatic compartment

Following GHS, the substance is not to be classified as acutely 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 are greater than 1 mg/L. The lowest ErC50 is 2.8 mg/L (P. subcapitata, NITE, 1997).

Following GHS, the substance is to be classified as chronically hazardous to the aquatic environment (Category Chronic 3).

Chronic data are available for algae, Daphnia and fish. Therefore classification is based on chronic toxicity data alone.

The substance is rapidly degradable and the lowest NOEC is 0.85 mg/L (Daphnia, NITE, 1997). According to the criteria outlined in Table 4.1.0(b) (ii) (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).
