There are no investigations on the degradation in soils of the
test substance. Nevertheless, based on results of a biodegradation study
(OECD guideline 301C) 4-nitrotoluene-2-sulphonic acid was assessed to be
poorly biodegradable (3 % after 28 days). Therefore, biotic degradation
is not expected in any further soil simulations studies. Consequently,
4-nitrotoluene-2-sulphonic acid is assessed to be persistent in the
