Applicant's summary and conclusion
- Conclusions:
- Half-life period of Disodium 4-hydroxy-3-[(4-sulphonatonaphthyl)azo]naphthalene sulphonate (CAS No. 3567-69-9) in water is observed to be 60 days (1440 hrs.) while in sediment it is 542 days (13000 hrs). Based on these half-life values of Disodium 4-hydroxy-3-[(4-sulphonatonaphthyl)azo]naphthalene sulphonate (CAS No. 3567-69-9), it is concluded that the chemical is persistent in both water and sediment medium.
