Official classification regarding environmental hazards
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.
Following GHS, the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available acute and chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment.
The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is >> 1 mg/L (48-h EC50 for aquatic ivnertebrates: 44.5 mg/L).
Experimentally derived chronic data are available for two trophic levels: Daphnids and algae; therefore, the classification is based on the available chronic and acute toxicity data.
- Chronic toxicity data:
Experimentally derived chronic data are available for aquatic invertebrates (21-d EC10: 8.1 mg/L) and for freshwater algae (72-h ErC10: 31.5 mg/L). The chronic effect value for fish, which was derived using the ACR method, resulted in a NOEC > 1 mg/L. These values are indicating that the substance 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:
As fish is the trophic level not covered by experimentally derived chronic data (ACR method: NOEC > 1 mg/L), the asessment is also based on the respective available acute toxicity data. Acute toxicity to fish is >>1 mg/L (96h LC50 for fish: > 100 mg/L). The substance is rapidly biodegradable (freshwater); the measured BCF is < 500. 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.
