Conclusion on classification

Official classification:

Aquatic compartment

According to Regulation (EC) No 1272/2008 Annex VI Table 3 the substance holds no relevant classification.

 

Self-classification:

Aquatic compartment

Following CLP (GHS-EU) the substance is not considered to be acutely hazardous to aquatic organisms.

Following CLP (GHS-EU) the substance is considered to be chronically hazardous to aquatic organisms (Category Chronic 3).

 

Rationale:

According to the criteria outlined in Table 4.1.0(a) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance (CAS 102-69-2) is not to be classified as acutely hazardous to the aquatic environment since the lowest available acute effect value (LC/EC50) is > 1 mg/L (Algae, 72 h EC50 = 22.4 mg/L, BASF AG, 1989, Rep. no. 89/1742).

 

Long-term toxicity data are available for algae only. Therefore, classification is based on the available chronic data and on acute toxicity data for the trophic level not covered by chronic data (fish and daphnia).

 

Chronic toxicity data:

The lowest EC10 is > 1 mg/L (Desmodesmus subspicatus, 72 h ErC10 = 9.03 mg/L, BASF AG, 1989, Rep. no. 89/1742) indicating that the substance does not present a long-term hazard according to the categories 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.

 

Acute toxicity data:

The 96 h LC50 determined for fish is 50.9 mg/L (Pimephales promelas, Geiger et al., 1986). The EC50 for aquatic invertebrates is 99 mg/L (Daphnia magna, BASF AG, 1990, Rep. no. 01/89/1742). The substance is not rapidly degradable, the log Kow is < 4, and the BCF value is < 500. Therefore, 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).

 

Atmospheric compartment

The test substance is not listed 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. In: Climate Change 2007: The Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change.

 

Conclusion:

Based on the available information, the substance is considered to be chronically hazardous to aquatic organisms (Category Chronic 3).
