Trace element concentrations among functional feeding groups in the estuarine food web in Middle Hempstead Bay, Long Island, New York
Estuaries are productive ecotones that are vulnerable to anthropogenic contamination due to human population density, overharvesting of marine resources, and an increase in urbanization and industrialization along coastlines. Most estuaries in the United States exhibit impaired water quality due to...

Estuaries are productive ecotones that are vulnerable to anthropogenic contamination due to human population density, overharvesting of marine resources, and an increase in urbanization and industrialization along coastlines. Most estuaries in the United States exhibit impaired water quality due to ongoing and legacy contamination. Middle Hempstead Bay is an estuarine ecosystem within the South Shore Estuary Reserve, on Long Island, New York, made up of densely clustered salt marsh islands that house multiple recreationally harvested (e.g., summer flounder, Paralichthys dentatus; blue crab, Callinectes sapidus; blue mussel, Mytilus edulis; and hard clam, Mercenaria mercenaria) and vulnerable species (e.g., piping plover, Charadrius melodus and diamondback terrapin, Malaclemys terrapin). This study investigated the concentration of six essential (Co, Cu, Fe, Mn, Se, Zn) and four nonessential (As, Cd, Hg, Pb) trace elements in sediments and in 27 estuarine species from Middle Hempstead Bay. Species were placed into functional feeding groups (FFGs) composed of species that feed or gain energy via the same general pathway; FFGs are commonly used to examine patterns in contaminant concentrations and behavior in food webs. Finally, differences in the tissue distribution of trace elements among four species [saltmarsh cordgrass (Spartina alterniflora), summer flounder, common tern (Sterna hirundo), and black skimmer (Rycops niger)] was examined.
