Biodegradation is soil
14C-radiolabelled TBBPA-DBPE was applied onto 4 different soils. Soils
were incubated at aerobic conditions in the dark up to 121 days. Further
sterillized subsamples of each soil were prepared and also treated with
the radiolabelled test item at the same time.
Total recovery of radioactivity from the samples was predominantly above
97% of the initial total radioactivity(ITR) in the sterilized subsamples
as well as in the non-sterile subsamples. From the recovered
radioactivity only minor amounts (3% maximum) were due to non
extractable residues which could not be defined by chemical analysis.
All the rest was identified as unchanged 14C-TBBPA-DBPE. Volatiles were
detected only in trace amounts.
From the results of the study the test item is assessed to be stable
against transformation in soils at aerobic conditions.
