Description of key information
Half life period of Tris(5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonato(2-))dialuminium in water is observed to be 60 days (1440 hrs.) while in sediment it is 541.66 days (13000 hrs). Based on these half life values of Tris(5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonato(2-))dialuminium, it is concluded that the chemical is not persistent in water and persistent in sediment.
Key value for chemical safety assessment
- Half-life in freshwater:
- 60 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 541.66 d
- at the temperature of:
