Applicant's summary and conclusion
- Conclusions:
- 3-amino-4-hydroxybenzenesulphonic acid showed 50% biodegradation in 720 h (30 days) in soil. Its half-life in soil, 30 days, does not exceed the EPA criteria of 60 days. Therefore, 3-amino-4-hydroxybenzenesulphonic acid is estimated not to be persistent in the environment, i.e., 3-amino-4-hydroxybenzenesulphonic acid is readily biodegradable in soil.
- Executive summary:
3-amino-4-hydroxybenzenesulphonic acid showed 50% biodegradation in 720 h (30 days) in soil. Its half-life in soil, 30 days, does not exceed the EPA criteria. Therefore, 3-amino-4-hydroxybenzenesulphonic acid is estimated not to be persistent in the environment, i.e., 3-amino-4-hydroxybenzenesulphonic acid is readily biodegradable in soil.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
