Item Bioavailability of Persistent Organic Pollutants in Fish from Gunston Cove (Potomac River Watershed, Virginia)(2013-08-16) Moody, Adam; Moody, Adam; Foster, Gregory D.Three classes of Persistent Organic Pollutants (POPs): Polycyclic Aromatic Hydrocarbons (PAHs), Polychlorinated Biphenyls (PCBs) and Organochlorine Pesticides (OCPs) were investigated in aquatic biota and bed sediments from an embayment-river mainstem of the Potomac River. Mean sediment concentrations ranged from 2.85 * 10^3 to 3.27 * 10^3 ng g^-1 for total-PAHs, 27.9 to 29.6 ng g-^1 for total-PCBs, 1.42 to 1.66 ng g^-1 for 4,4’-DDE and 0.65-0.66 ng g^-1 for γ-chlordane. A greater portion of high molecular weight PAHs were present in the bed sediments indicating high contribution of pyrogenically-derived PAHs. Consensus-based Threshold Effect Concentrations (TECs) have been compared to concentrations of total-PAHs, individual PAHs, total-PCBs and individual OCPs. Mean concentrations of POPs in fish tissue ranged from 5.4 to 34.3 ng g^-1 for total-PAHs, 40 to 116 ng g^-1 for total-PCBs, 14.0 to 28.9 ng g^-1 for 4,4’-DDE and
