Additional information

Conclusion on classification

Classification related key information

The concept of ready biodegradability does not apply to inorganic substances.

Significant bioaccumulation in biota is not expected for this substance (see IUCLID section 5.3).

Acute toxicity:

-          Fish: LC50(96h)> 100 mg/L (nominal); read across

-          Aquatic invertebrates:EC50(48 h) >100 mg/L (nominal); read across

-          Algae:EC50(72 h) >100 mg/L (nominal); read across

Chronic toxicity: 

-          Aquatic invertebrates: NOEC (21 d): 1.5 mg/L (nominal); read across

-          Algae: NOEC (72 h) ≥ 100 mg/L (nominal); read across

Conclusion on classification

The substance has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are > 100 mg/L (nominal) for fish, aquatic invertebrates and algae. The NOEC in a chronic toxicity study on Daphnia magna is 1.5 mg/L Thus the substance does not need to be classified and labelled according to the 6th ATP of Regulation (EC) No.1272/2008 (CLP).
