Description of key information

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.

Additional information

Bioaccumulation

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.
