Conclusion on classification

Short-term toxicity data are available for all three trophic levels. The most sensitive species was Daphnia magna (48 -h EC50 = 34.1 mg/L; BASF SE, 2011; project no. 50E0117/10E112). Chronic toxicity data are available for two trophic levels: Daphnia (21-d EC10 = 4.7 mg/L) and algae (72 -h ErC10 = 75.6 mg/L). Therefore chronic effects are not expected.

Official classification regarding environmental hazards:

Aquatic compartment

In accordance with Regulation (EC) No 1272/2008 Annex VI Table 3.1 or Table 3.2: no data found for the Reaction product of 2,4-Dinitrotoluene and 2,6-Dinitrotoluene and hydrogen or one of its major components (CAS 13897 -55 -7 or CAS 13897 -56 -8).

 

Self-classification

Aquatic compartment

Following GHS, the substance is not to be classified as acutely or chronically hazardous to the aqueous environment.

Rationale:

Following CLP (GHS-EU), the substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is greater than 1 mg/L.

Chronic data are available for Daphnia (21 -d EC10 = 4.7 mg/L) and algae (72-h ErC10 = 75.6 mg/L); therefore, classification is based on the available chronic

(Daphnia, algae) and acute toxicity (fish; 96 -h LC50 > 120 mg/L) data.

- Chronic toxicity data: The substance is not rapidly degradable, and the available chronic effect values (EC10) are greater than 1 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 not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data: Fish is the trophic level not covered by chronic data. Therefore, classification is also assessed based on the respective acute effect data. The LC50 is greater than 100 mg/L, the substance is not rapidly degradable and the log Pow is < 4. Therefore, the substance is not to be classified as chronically hazardous.
