Step 2: Describing the receptors and exposure pathways

There are several potential pathways by which people may be exposed to

contaminants in dredged material at a management site. Individual exposures occur

either through direct or indirect exposure pathways. Potential direct exposure

pathways include dermal contact and ingestion of contaminated sediments or surface

water. Indirect exposure pathways include ingestion of seafood (finfish and
