studies in carp, rainbow trout, lake trout, food webs
DecaBDE has been studied for
bioconcentration, bioaccumulation, and biomagnification potential. A
bioconcentration factor of < 50 was measured in a 6 wk fish
bioconcentration study. Uptake of DecaBDE from food rainbow trout over
120 d was ~0.02-0.13% of the dose. Uptake by carp from food was ~0.39%
of the dose over a 90 day period. The food assimilation efficiency of
DecBDE by lake trout was reported to be 0.3. Biomagnification was not
observed in Lake Michicgan or Baltic Sea food webs.
These results indicate DecaBDE has minimal
potential for bioconcentration, bioaccumulation, or biomagnification.
This is consistent with its physcial/chemical properties and results of
mammalian absorption, distribution, and elimination studies. For
example, the rat absorbed approximately 0.33% of a dietary dose.
