The substance is expected to be not readily biodegradable.
From assessment of similar sulphonated azo dyes, it is considered
unlikely that the substance will be readily biodegradable. A number of
studies using OECD screening methods have been assessed with a range
between 0 – 38% biodegradation. It is likely that the sulphonated azo
substances showing higher rates of biodegradation are most likely due to
side groups that are more easily metabolised or cleave off the main
Literature checks suggest that there is little concern about
long-term persistence and there is evidence that a combination of biotic
and abiotic processes will break down these substances in the
environment; this is apparently likely in waste water treatment
processes as well as natural soils and sediments.
As no claim is made that CJ313 is readily biodegradable, this
grouping approach is considered to be valid.
