Additional information
Conclusion on classification
Acute toxicity data are only available for aquatic invertebrates and algae (daphnids: 48-h EC50 = 27.9 mg/L, measured, BASF SE, 2014; algae: 72-h ErC50 = 19.8 mg/L, measured, BASF SE, 2014); chronic toxicity data are only available for algae (72-h ErC10 = 5.92 mg/L, measured, BASF SE, 2014).
Official classification regarding environmental hazards
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
Acute (short-term) aquatic hazard
Following CLP, 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 available acute effect value is > 1 mg/L (aquatic algae: 72-h ErC50 = 19.8 mg/L, measured, BASF SE, 2014).
Long-term aquatic hazard
Following CLP, the substance is not to be classified as chronically hazardous to the aquatic environment.
Rationale:
Acute toxicity data are only available for aquatic invertebrates and algae; chronic data are only available for algae. Therefore, the classification is based on the available chronic and acute toxicity data:
Chronic toxicity data:
The only available chronic toxicity data are on aquatic (72-h ErC10 = 5.92 mg/L, measured, BASF SE, 2014). The substance is rapidly biodegradable. 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 not to be classified as chronically hazardous to the aquatic environment.
Acute toxicity data:
Aquatic invertebrates is the trophic level not covered by chronic toxicity data; therefore, the assessment is based on the available acute data (48-h EC50 = 27.9 mg/L, measured, BASF SE, 2014). The substance is rapidly degradable; the log Kow 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: The substance is not to be classified as chronically hazardous to the aquatic environment.
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 Pamaswamy et al. Changes in Atmospheric Constituents and Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Goup 1 to the Fourthe Assessment Report of the Intergovernmental Panel on climate Change.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
