3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is 50% biodegradable in water in 38 days (half-life) indicating that it is not persistent (readily biodegradable) in water while in sediment in it is 50% biodegradable in 340 days(8160 hrs) (half-life) indicating that it is persistent(not readily biodegradable) in sediment.
Based on level III fugacity model the half
life period of 3-acetamido-5-amino-4-hydroxybenzenesulphonic
acid was estimated. Half life period
acid in water was observed to be 38
days while in sediment it is 340 days. From these half life values it is
concluded that 3-acetamido-5-amino-4-hydroxybenzenesulphonic
acid is readily biodegradable (non
persistent) in water where as it is non biodegradable (persistent) in
However it has been observed that 3-acetamido-5-amino-4-hydroxybenzenesulphonic
acid does not diffuse in the sediment
medium since its percentage in the sediment medium is reported to be 0%
and hence persistence in the sediment medium is not likely to be critical
