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) > 0.207 mg boron/ L meas. arithm. mean (> 100 mg/L nominal test substance conc.)

-            Aquatic invertebrates: EC50 (48h) > 0.135 mg boron/ L meas. arithm. mean (> 100 mg/L nominal test substance conc.)

-            Algae: EC50 (72h) > 1.35 mg boron/L meas. initial (> 100 mg/L nominal test substance conc.)

 

Chronic toxicity: 

-            Aquatic invertebrates: NOEC (21 d) ≥ 494 µg/L (TWM) (≥ 3.75 mg/L nominal test substance conc.)

-            Algae: NOEC (72h) ≥ 1.35 mg boron/L meas. initial (≥ 100 mg/L nominal test substance conc.)

 

Conclusion on classification

The substance has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 and NOECalgae values are > 100 mg/L (nominal test substance conc.) for fish, aquatic invertebrates and algae. The NOEC in a chronic toxicity study on Daphnia magna is ≥ 3.75 mg /L (nominal test substance conc.). Thus the substance does not need to be classified and labelled for environmental toxicity according to the 6th ATP of Regulation (EC) No.1272/2008 (CLP).
