Conclusion on classification

Short-term toxicity data are available for all three trophic levels. The most sensitive species with regard to acute toxicity was Ceriodaphnia dubia (48-h EC50 = 4.6 mg/L). Chronic toxicity data are available for two trophic levels: Daphnia (21-d EC10 = 4.1 mg/L) and algae (72-h ErC10 = 34.3 mg/L).

 

Official classification regarding environmental hazards:

Aquatic compartment

In accordance with Regulation (EC) No 1272/2008 Annex VI Table 3.1 or Table 3.2: officially not classified.

  

Self-classification

Aquatic compartment

Following CLP (GHS-EU), the substance is not to be classified as acutely or chronically 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 value is > 1 mg/L.

- Chronic data are available only for Daphnia and algae (EC10 > 1 mg/L); therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The EC10 values are greater than 1 mg/L. The substance is rapidly degradable and its calculated BCF (weight-of-evidence approach) is < 500.The chronic data indicate that diethylamine does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances.

- Acute toxicity data:The substance is rapidly degradable, the experimentally determined BCF is < 500. The acute effect value for fish, which are not covered by chronic toxicity data, is greater than 100 mg/L. Therefore no long-term hazard exists based on the categories outlined in Table 4.10(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008).
