Since the 1980's, the USEPA Great Lakes Fish Monitoring and Surveillance Program (GLFMSP) has monitored legacy organic pollutants in the Great Lakes' top predator fish as part of the US-Canadian Great Lakes Water Quality Agreement. Although considerable concern still exists, publications by our multi-campus collaboration have recently reported significant downward trends in polychlorinated biphenyls (PCBs - Chang et al., 2012); polybrominated diphenyl ethers (PBDEs - Crimmins et al., 2012); and toxaphene (Xia et al., 2009 and 2011). As part of the GLFMSP �surveillance� program we analyzed whole fish composite samples to identify chemicals of emerging concern in the environment based on their production volume, persistence, bioaccumulative potential, and toxicity. Our working group has identified several flame retardant chemicals in Great Lakes fish with gas chromatography - high resolution mass spectrometric techniques. We will report the overall status and trends of legacy and emerging chemicals in Great Lakes fish.
