Description of key information

The half life period of 4-aminobenzene-1,3-disulphonic acid in water is 15 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half life is less than the threshold of 60 days (to qualify the chemical as persistent).

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The half life period of 4-aminobenzene-1,3-disulphonic acid in water is 15 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half life is less than the threshold of 60 days (to qualify the chemical as persistent). Also the diffusion percentage of 4-aminobenzene-1,3-disulphonic acid in water medium is 24%. This coupled with the dilution of water shall result in ready biodegradabililty of the chemical.
