All validity criteria were met.
Degradation behaviour of positive control and toxicity control was
normal. Abiotic degradation reached 4 %. Both replicates of the test
item showed very good correspondence.
Degradation values of more than 100 % were calculated. This is due
to the fact that the measurement errors of test flasks and control
flasks add up when using the equation proposed in the guideline.
If degradation in the toxicity flask is below 25 % after 14 days,
the testitem can be considered as toxic towards the inoculum. As
degradation in the toxicity flask was 46.2 % after 14 days, the test
item can be stated as “not toxic towards the inoculum in a concentration
of 29.4 mg/L”.
Ready degradability is defined in the guidelines as degradation
surpassing 60% within 10 days after reaching a level of 10 %. Therefore,
the test itemN-(4-anilinophenyl)-4-methylbenzenesulfonamidecan be
considered as “not readily biodegradable”. Degradation
missed 60% within 28 days, though. Therefore, the test item can be
considered as “not ultimately biodegradable within 28 days, either.
No observations were made which might cause doubts concerning the
validity of the study outcome.
The result of the test can be considered valid.
