- Biodegradation half-life of test substance (5Or8)-aminonaphthalene-2-sulphonic acid in soil was estimated to be 75 days (1800 hrs).
- Executive summary:
Based on EPI prediction Level III Fugacity Model (EPI suite, 2016), the estimated half-life period of (5Or8)-aminonaphthalene-2-sulphonic acid (CAS No. 51548 -48 -2) in soil was obtained to be 75 days (1800 hrs). Based on this half-life value of (5Or8)-aminonaphthalene-2-sulphonic acid, it is concluded that the chemical is not persistent in the soil environment.
