Description of key information

The atmospheric oxidation half-life of 4,4'-dinitrostilbene-2,2'-disulphonic acid was estimated using the level III multimedia model. It was estimated that the substance is not persistent in air medium as the half life period of 4,4'-dinitrostilbene-2,2'-disulphonic acid in air is only 0.071 days. This indicates that 4,4'-dinitrostilbene-2,2'-disulphonic acid is easily phototransformed in air.

Key value for chemical safety assessment

Half-life in air:
0.071 d
Degradation rate constant with OH radicals:
0 cm³ molecule-1 s-1
