Development of environmental fate model for hexabromocyclododecanes(HBCDS) with isomerisation process

Introduction

Environmental fate 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. The purpose of this study is to assess the impact of the isomerisation process on the environmental fate model for HBCDs.
