Applicant's summary and conclusion
- Conclusions:
- The atmospheric oxidation half life of 3-amino-4-hydroxybenzenesulphonic acid was estimated using level III multimedia model it indicates that 3-amino-4-hydroxybenzenesulphonic acid is not persistent in air medium as the half life period of 3-amino-4-hydroxybenzenesulphonic acid in air is only 1 days. From this it is concluded that 3-amino-4-hydroxybenzenesulphonic acid is rapidly phototransformed in air.
- Executive summary:
The atmospheric oxidation half life of 3-amino-4-hydroxybenzenesulphonic acid was estimated using level III multimedia model it indicates that 3-amino-4-hydroxybenzenesulphonic acid is not persistent in air medium as the half life period of 3-amino-4-hydroxybenzenesulphonic acid in air is only 1 days. From this it is concluded that 3-amino-4-hydroxybenzenesulphonic acid is rapidly phototransformed in air.
