Additional information

Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

The Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2 holds no available information on the substance.

Self-classification

Aquatic compartment

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.

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 for algae and Daphnia, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available for algae (72h ErC10 >100 mg/L) and Daphnia (21 -d NOEC ≥ 12 mg/L). According to the categories outlined in Table 4.1.0(b)(i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for non-rapidly degradable substances, the substance does not represent a long-term aquatic hazard.

-Acute toxicity data:

Chronic data are not available for fish. Following table 4.1.0 (b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for this trophic level as adequate chronic toxicity data are not available, the substance is to be classified as chronically not hazardous to fish since the acute toxicity value is determined to be > 100 mg/L (96h LC50, Leuciscus idus; geom. mean LC50: 147 mg/L). The substance is not rapidly biodegradable (freshwater) but the log Kow is <4.

In conclusion, the substance is not to be classified as chronically hazardous to the aquatic environment.
