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:
- Fish NOEC (28 d): 4.7 to 23.1 mg/L ; read across
- Aquatic invertebrates: NOEC (21 d): 1.5 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).
