Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to the Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2, the substance (CAS 87-62-7) holds the classification Aquatic Chronic 2.

 

Self-classification

Aquatic compartment

 

Following GHS, 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 for aquatic invertebrates and algae; therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available for daphnia and algae (NOEC (21 -d) = 2.2 mg/L; NITE, Japan, 2002; data published) indicating that the substance does not present a long-term hazard 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. Based on the chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data:

The lowest effect value for acute toxicity to aquatic organisms (LC/EC50) is less than 100 mg/L. (EC50 (48 h) = 20 mg/L, Daphnia magna, NITE, Japan, 2002, data published) .

The substance is not rapidly biodegradable and the log Kow is <4. Based on the acute data, the substance is to be classified as category Chronic 3.

However, based on the available experimental data and considering the harmonized classification of the Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2, the substance (CAS 87-62-7) is considered to be classified as Aquatic Chronic 2.
