Abstract

Hexabromocyclododecane (HBCDD) is a brominated flame retardant (BFR) that is commonly used as part of building insulation and in many household items. The global production volume of this BFR reported to be 600,000 tons per year in 2001.  Due to the toxic and persistent nature of this compound multiple regulatory agencies have begun monitoring HBCDD levels in the environment and food. As a part of Great Lakes Fish Monitoring and Surveillance Program (GLFMSP), an analytical method for measuring the concentration of three HBCDD isomers in whole fish has been developed. Different extraction techniques were evaluated using ultra-high pressure liquid chromatography quadrupole time of flight mass spectroscopy (UPLC-QTOF). The optimized method was then used to measure the concentrations of HBCDD in lake trout (Salvelinus namaycush) and walleye (Sander vitreus) from each of the Laurentian Great Lakes. The spatiotemporal trends of total HBCDD will be presented. In addition, possible sources and overall behavior of HBCDD will be explored relative legacy chemicals currently monitored in the Great Lakes.
