During a study in accordance with OECD TG 301B for ready biodegradability, very low biodegradation was observed after 28 days (18%).
All validity criteria were met.
Degradation behaviour of positive control and toxicity control was
normal. Abiotic degradation was not observed. Both replicates of the
test item showed very good correspondence.
If degradation in the toxicity flask is below 25% after 14 days,
the test item can be considered as toxic towards the inoculum. As
degradation in the toxicity flask was 42% after 14 days, the test item
can be stated as “not toxic towards the inoculum in a concentration of
Ready degradability is defined in the guidelines as degradation
surpassing 60% within 10 days after reaching a level of 10%. Therefore,
the substance can be considered as “not readily biodegradable”.
Degradation missed 60% within 28 days, though. Therefore, the test item
is 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.
