Description of key information
The PBT Profiler & EPI Suite has estimated that 4,4'-dinitrostilbene-2,2'-disulphonic acid is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life in soil, 120 days., exceeds the threshold (60 days) of being persistent in soil.Therefore, 4,4'-dinitrostilbene-2,2'-disulphonic acid is estimated to be persistent in the soil environment. The substance 4,4'-dinitrostilbene-2,2'-disulphonic acid diffuse to the extent of 82% in the soil medium.
Key value for chemical safety assessment
- Half-life in soil:
- 120 d
- at the temperature of:
- 25 °C
