The study to determine the BMF of bis(2-ethylhexyl)
tetrabromophthalate (TBPH) was conducted according to OECD guideline
305. The resulting BMFkgL of 0.038 (after 28 days for
uptake, and another 28 days for depuration) indicates that
bis(2-ethylhexyl) tetrabromophthalate (TBPH) is not bioaccumulative to
fish of the species Oncorhynchus mykiss when applied orally and uptake
results via the digestive tract.
After 28 days for uptake, and another 28 days for depuration a kinetic
BMFk of 0.004 was determined subsequently, which was
corrected for growth dilution effects resulting in a BMFkg of
0.014. Finally, a lipid-correction of the BMF was conducted, in order to
standardize the BMF for comparative analyses of the results. The
resulting BMFkgL of 0.038 indicates that TBPH is not
bioaccumulative to fish of the species Oncorhynchus mykiss when applied
orally and uptake results via the digestive tract. The critical
threshold for classification of substances to be bioaccumulative are BMF
values >1 as suggested in the guidance document of the European
commission for delivering environmental standards.
