The test material has been determined not to be readily biodegradable.
As part of an investigation to determine the ready biodegradability of a
number of substances, the ready biodegradability of the test material
was investigated in a respirometry test that followed the same principle
as that in the standardised guideline OECD 301 F, except that it did not
include the abiotic and toxicity checks and pre-adapted inoculum was
employed. The study was conducted under GLP conditions.
The inoculum was adapted to the test material for 14 days before test
initiation and the degradability was expressed as the ratio of the
measured Biological Oxygen Demand (BOD) and the Theoretical Oxygen
Demand (ThOD; calculated from the elemental analysis of the substance).
The initial test material concentration was 100 mg/L and the temperature
throughout the 28 day test was 23 ± 1 °C. Oxygen consumption was
measured with a BI-1000 electrolytic respirometer system; the oxygen
uptake in all flasks were monitored continuously and recorded
automatically every 4 hours throughout the test period. Sodium benzoate
was employed as reference material.
The level of biodegradation at the end of the 28 day test period for the
test material was 18.3 % (average of two replicates). The reference
substance reached a biodegradation level of 94.3 % in the same test
Under the conditions of the study, the test material has been determined
not to be readily biodegradable.
