Description of key information

Half life period of 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid  in Soil was observed to be 75 days.Based on these half life values it is concluded 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is not readily biodegradable (persistent) in soil.

Key value for chemical safety assessment

Half-life in soil:
1 800 h
at the temperature of:
25 °C

Additional information

The PBT Profiler & EPI Suite has estimated that 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is expected to be found predominantly in soil and its persistence estimate is based on its availability in this medium. Its half-life in soil, 1800 hrs (75 days). This exceeds the EPA criteria of >= 2 months (and <= 6 months). Therefore, 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is estimated to be persistent in the soil environment.
