摘要: ABSTRACT The objectives of this study were to (1) determine if historical exceedences oil and grease concentrations above the limits allowed in National Pollution Elimination Discharge System permit for wastewater treatment facility Motiva Enterprises LLC Refinery, Delaware City, Delaware, could be determined from sedimentary records River and, so, (2) contaminants high enough toxic aquatic biota. Eighty-four surficial sediment samples, both within outside influence Refinery's discharge plume, initially evaluated their appropriateness coring. Seven stations ultimately selected core studies. Based on type, radionuclide (Pb-210, Cs-137 Be-7) geochronologies, proximity cores two more detailed polycyclic aromatic hydrocarbon (PAH) analyses. rapid accumulation area one (located near-field discharge...
