Description of key information

The 3h-EC50 for STP micro-organisms was determined to be 14.7 mg NBDA/L

Key value for chemical safety assessment

Additional information

A study was performed with STP micro-organisms, using a 3 -hour incubation period. Considering the hydrolytic instability of NBDI, the observed toxicity is likely to be caused by NBDA. The EC50 was recalculated from the reported EC50 expressed in mg NBDI/L into a value expressed in mg NBDA/L by correction for molecular weights of the substances.

Value used for CSA: EC50/LC50 for aquatic micro-organisms: 14.7 mg NBDA/L
