Half life period of (3-aminophenyl)uronium chloride in water is observed to be 38 days (912 hrs.) while in sediment it is 340 days (8160 hrs).Based on these half life values of (3-aminophenyl)uronium chloride , it is concluded that the chemical is readily biodegradable in water where as it is non biodegradable in sediment. However, since there is no diffusion of the substance in the sediment hence persistence in the sediment compartment is not likely to be critical
Based on the Level III Fugacity Model, the half life period of the
(3-aminophenyl)uronium chloride was estimated. The half period of
(3-aminophenyl)uronium chloride in water is 38 days (912 hrs) therefore
it is considered that the substance will qualify as not persistent as
the half life does not exceed the EPA criteria of 60 days. So, it can be
confirmed that the substance is readily biodegradable in water medium
where as in sediment the half life is 340 days (8160 hrs).
Based on this value, it can be inferred that the substance is persistent
in sediment medium and is not readily biodegradable probably due to the
anaerobic conditions existing in most sediments. However, it can be
observed that (3-aminophenyl)uronium chloride have no diffusion in the
sediment medium hence persistence in the sediment compartment is not
likely to be critical.
