What values do I use to screen / evaluate exposure via food chain exposure? Does Region 3 have screening values that address this route of exposure?
The Region 3 BTAG has not developed food chain exposure screening values. NOAEL-based values must be obtained from the literature for the receptor species (or its surrogate) selected for evaluation in the screening level assessment. When applicable and available, EPA’s Ecological Soil Screening Levels for food chain exposure should be utilized. Adequate documentation for the use and applicability of each value must be provided. The risk assessor should consult with BTAG prior to initiating the development of these values and discuss the format for the presentation of the data that is to be evaluated and considered.
