Abstract

Hexaboromocyclododecane (HBCD) and Tetrabromobisphenol A (TBBPA) are brominated flame retardants (BFRs) that are commonly used as part of building insulation and in many common household items. The annual production volume of these BFRs exceeds 100,000 tons per year since 1998.  Due to the toxic and persistent nature of these compounds multiple regulatory agencies have started to monitor there levels in the environment and food. Therefore, as a part of Great Lakes Fish Monitoring and Surveillance Program (GLFMSP), an analytical method for measuring the concentration of three HBCD isomers and TBBPA in fish tissue has been developed. Different extraction techniques were evaluated prior to analysis of the samples using liquid chromatography coupled to high resolution mass spectroscopy (LC-HRMS). Using the optimized method HBCD and TBBPA levels of fish from all Great Lakes from 2004-2016 have been determined to establish spatial and temporal trends.
