Description of key information

The effective concentration (EC50) value based on QSAR prediction of biphenyl-2-ylamine in aquatic algae (Pseudokirchnerella subcapitata) in 72 hrs was estimate to be 11.782361984 mg/l. 

Key value for chemical safety assessment

EC50 for freshwater algae:
11.782 mg/L

Additional information

The effective concentration (EC50) value based on QSAR prediction of biphenyl-2-ylamine in aquatic algae (Pseudokirchnerella subcapitata) in 72 hrs was estimate to be 11.782361984 mg/l.

Therefore the EC50 was considered to be 11.782361984mg/L for biphenyl-2-ylamine and it is not readily biodegradable in nature indicating that test substance likely to exhibit toxicity to aquatic algae in aquatic chronic 3 category as per the Harmonized CLP classification.
