Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1: no data available

According to Regulation (EC) 1272/2008 Annex VI Table 3.2: no data available.

 

Self-classification

Aquatic compartment

Following DSD/DPD, the substance is to be classified as dangerous for the aquatic environment (N, R50/53).

Rationale:

The lowest acute toxicity to aquatic organisms (LC/EC50) is below 1 mg/L and the substance is not readily biodegradable.

 

Following GHS, the substance is to be classified as acutely (acute 1) and chronically (chronic 1) hazardous to the aquatic environment.

Rationale:

The substance is to be classified as acutely hazardous to the aquatic environment (acute 1), since the lowest acute effect value is below 1 mg/L (algae: EC50 (72 h) >0.5 mg/L).

Chronic data are available only for algae. Therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The substance is not rapidly degradable and the ErC20 (neither ErC10 nor NOErC are available) is below 0.1 mg/L (algae: EC20 (72 h) 0.0078 mg/L). 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 to be classified as chronically hazardous to the aquatic environment (chronic 1).

- Acute toxicity data: Fish and Daphnia are the trophic levels not covered by chronic data. Therefore classification is based on the respective acute effect data. The lowest LC/EC50 is between 10-100 mg/L, the substance is not rapidly degradable and the log Pow is expected to be < 4. Therefore, based on acute data the substance is to be classified as chronically hazardous (chronic 3).

Conclusion: Following GHS, the substance is to be classified as acutely (acute 1) and chronically hazardous (chronic 1) to the aquatic environment.

- M-factors:

M-factor acute: 1 (rationale: L(E)C50 value: 0.1 <L(E)C50 </=1);

M-factor chronic: 10 (rationale: 1. NRD component; 2. NOEC value (=EC20 algae): 0.001 <NOEC </=0.01)

 

Atmospheric compartment

The test substance is not 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.
