INTAKE FRACTIONS OF HBCDS

Introduction
Environmental fate and exposure of hexabromocyclododecanes is important for the characterization of their risks. Arnot et al. 1 presented a comprehensive collection and critical review of available physical-chemical property and transformation data for technical-HBCD, α-HBCD, β-HBCD and γ-HBCD. However, due to the limited availability of data, isomerisation process was not included in the model calculation. In our previous study2, we assessed the impact of the isomerisation process on the environmental fate model for HBCDs. However, exposure modelling was not included in the study. In this paper, we developed environmental fate and exposure model for HBCDs and calculated the intake fractions (iFs) for these compounds.
