Additional information
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.
