Description of key information

The No observed effect concentration (NOEC) value of 5-nitro-o-anisidine in green algae (Pseudokirchnerella subcapitata) in a 72 hr study was estimated to be 6.645622mg/L (growth effect). But the BCF value of 5-nitro-o-anisidine reported was not >= 500 as well as the substance was found to be rapidly degradable.Thus considering the CLP Criteria for aquatic classification of the substance , it is concluded that 5-nitro-o-anisidine could not exhibit short term toxicity to green algae (Pseudokirchnerella subcapitata) 

Key value for chemical safety assessment

EC50 for freshwater algae:
98 mg/L
EC10 or NOEC for freshwater algae:
6.64 mg/L
