INTAKE FRACTIONS OF PBDES AND PBDD/DFS
Environmental fate and exposure model for PBDEs and PBDD/DFs were developed and intake fractions for PBDEs and PBDD/DFs were calculated. Debromonation of PBDEs to lower-brominted diphenyl ethers and formation of PBDFs from PBDEs were considered in the environmental fate model. The model predicted that the concentration of daughter PBDEs caused by debromination were 2 to 4 orders of magnitude lower than those of their parent PBDEs. Concentrations of PBDEs and PBDD/DFs were calculated based on two emission scenarios which focused mainly on DecaBDE sources. The estimated concentrations of PBDD/DFs were about 2 to 4 orders of magnitude lower than the observed concentrations of PBDD/DFs. This result suggests that the emission sources of PBDD/DFs and the emission sources of DecaBDE are quite different. Lower brominated PBDEs and PBDD/DFs had higher intake fractions than higher brominated compounds.
