Description of key information

The half-life period of 2,4-Diaminobenzenesulfonic acid (CAS No. 88 -63 -1) in soil was estimated using Level III Fugacity Model by EPI Suite version 4.1 estimation database (EPI suite, 2016. If released into the environment, 64.9% of the chemical will partition into soil according to the Mackay fugacity model level III. The half-life period of 2,4-Diaminobenzenesulfonic acid in soil is estimated to be 75 days (1800 hrs). Based on this half-life value of 2,4-Diaminobenzenesulfonic acid, it is concluded that the chemical is not persistent in the soil environment and the exposure risk to soil dwelling animals is moderate to low.

Key value for chemical safety assessment

Half-life in soil:
75 d
