Estimate exposure point concentrations (EPCs)
EPCs are the contaminant concentrations in the edible tissue of seafood from the
dredged material disposal site. The most reliable method for determining the EPCs
in the species of concern is by directly measuring the concentrations in the tissues of
the organisms. However, this is typically not an option, unless the seafood species
of interest can be collected from the dredging (project) site and their foraging area is
confined to that area or its area of influence.
