A Survey of Sportfish for Per- and Polyfluoroalkyl Substances (PFAS) – An Emerging Contaminant in the Great Lakes

Major Goals and Objectives

  • Determine the concentrations and speciation of PFAS in important Lake Michigan sportfish
  • Evaluate dietary routes for PFAS exposure from prey to predator fish using δ15N and δ13C stable isotopes along with PFAS speciation
  • Assess the relationship between total fluorine and PFAS concentrations to determine the full extent of the PFAS problem
  • Compare observed PFAS concentrations in fish from Illinois-Indiana waters to other areas such as inland Michigan waterways where PFAS are known to be a problem
