Description of key information

The half life period of 4,4'-dinitrostilbene-2,2'-disulphonic acid in water is 60 days and based on this value it can be concluded that the chemical is persistent in water medium and will not easily bio-degrade. Also the diffusion percentage of 4,4'-dinitrostilbene-2,2'-disulphonic acid in water medium was observed to be 7%.
