Additional information
Conclusion on classification
Official classification:
Aquatic compartment
According to Regulation (EC) No 1272/2008 Annex VI Table 3.2 the substance holds no relevant classification.
Self-classification:
Aquatic compartment
The substance is not classified as acutely or chronically hazardous to aquatic organisms.
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 764-99-8) is not to be classified as acutely hazardous to the aquatic environment since the lowest acute effect value is > 1 mg/L.
Long-term toxicity data are available for aquatic invertebrates and algae. Therefore, classification is based on these chronic data as well as based on the experimentally determined acute toxicity data for fish.
Chronic toxicity data:
The substance is rapidly degradable and the lowest long-term NOEC/EC10 is > 1 mg/L. According to the criteria outlined in Table 4.1.0(b) (ii) (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:
The L(E)C50 determined for all trophic levels are > 100 mg/L, the substance is rapidly degradable and the log Kow is < 4. 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.
It can be concluded that the substance (CAS 764-99-8) is not to be classified as chronically hazardous to the aquatic environment.
