Key Points

  • Evaluation of wildlife exposure for the USEPA Eco-SSLs and REACH incorporate broad exposure and effects assumptions to ensure that soil contaminants do not pose risks to wildlife, resulting in thresholds that may be low, with conclusions of risk possible at background soil concentrations.
  • Methods for quantifying exposure of wildlife to soil-associated metals through soil and food consumption were evaluated to provide recommendations for the development of ecological soil cleanup values (Eco-SCVs) that are both practical and scientifically defensible.
  • Existing exposure estimation models are generally appropriate when fully expanded, with improved realism possible through integration of more realistic and site-specific diet composition estimates, bioaccumulation, bioavailability, soil ingestion, habitat use, and target organ exposure.
  • These components of wildlife exposure estimation should be developed on a site-, species-, and analyte-specific basis to the extent that the expense for their derivation is justified by the value they add to Eco-SCV development.
