Description of key information

Based on QSAR prediction half life period of 5-nitro-o-anisidine in Soil was estimated to be 139 days.
Also from the other weight of evidnece study it is found that the substance is 50% degradable in 75 days which exceeds the EPA criteria of 60 days.
Based on these half life values it is concluded that 5-nitro-o-anisidine is not readily biodegradable (persistent) in Soil.

Key value for chemical safety assessment

Additional information

Based on QSAR prediction half life period of 5-nitro-o-anisidine in Soil was estimated to be 139 days.

Also from the other weight of evidnece study it is found that the substance is 50% degradable in 75 days which exceeds the EPA criteria of 60 days

Based on these half life values it is concluded that 5-nitro-o-anisidine is not readily biodegradable (persistent) in Soil.

No. of studies reviewed for biodegradation in water endpoints from reliable sources having Klimish rating 2

The summary of the results are presented below.
