Description of key information

The substance 5-nitro-o-anisidine degrades 87.6% in water in 28 days and thus it can be concluded that 5-nitro-o-anisidine is readily biodegradable in water. Also the half life of 5-nitro-o-anisidine is less than 60 days thus it is not persistent in water.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Based on the information collected from various sources for the biodegradation in water for 5-nitro-o-anisidine it was estimated that 5-nitro-o-anisidine degrades 87% in 28 days thus it can be concluded that 5-nitro-o-anisidine is readily biodegradable in water medium.

Based on the above information it can be concluded that the substance is readily biodegradable. Also the half life of 5-nitro-o-anisidine is less than 60 days the threshold criteria for persistence it can be concluded that 5-nitro-o-anisidine is not persistent in water according to criteria of CLP regulation.
