Description of key information
Half life period of 4,4'-dinitrostilbene-2,2'-disulphonic acid in water observed 60days.(half-life) while in sediment it is 540 days.(half-life). Based on this half life values of 4,4'-dinitrostilbene-2,2'-disulphonic acid, it is concluded that the chemical is non biodegradable in water and sediment medium.
Key value for chemical safety assessment
- Half-life in freshwater:
- 60 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 540 d
- at the temperature of:
- 25 °C
Additional information
Half life period of 4,4'-dinitrostilbene-2,2'-disulphonic acid in water observed 60days (half-life) while in sediment it is 540 days.(half-life).
The supporting study also indicates the half life of 4,4'-dinitrostilbene-2,2'-disulphonic acid in water and sediment to be 1440 hrs and 13000 hrs respectively.
Based on this half life values of 4,4'-dinitrostilbene-2,2'-disulphonic acid, it is concluded that the chemical is non biodegradable in water and sediment medium.
