“…The freshwater supplied by Pirros and Glafkos is considerably lower. Freshwater inputs are important for the system as they are directly linked with the particulate material transported from the land and as a result, with the pollutants adsorbed onto particles, which enter the sea (Lu and Matsumoto, 2005;Paller et al, 2005). Furthermore, low salinity fresh waters are mixed with the highly saline seawaters decreasing the surface salinity of the gulf near the river outlets and thus affecting the local regime (Uncles et al, 2000).…”

“…This was suggested by high mercury levels in fish from the tributary streams ( Figure 3) and by results from a previous study showing that methylmercury levels were elevated in tributary water and in clams (Corbicula fluminea) residing in the discharge plumes of Savannah River tributary streams (Paller et al, 2003). Tributaries and the floodplain wetlands they drain could have contributed to increased mercury levels in Savannah River fishes by discharging methylmercury that is dissolved and associated with particulate matter into the Savannah River where it entered the food chain and through the migration of relatively contaminated tributary fish into the river as observed with other contaminants (Paller et al, 2005).…”

Extensive and critical evaluation can be required to assess contaminant bioaccumulation in large predatory fishes. Species differences in habitat use, resource use, and trophic level, often influenced by body form, can result in diverging contaminant bioaccumulation patterns. Moreover, the broad size ranges inherent with large-bodied fish provide opportunity for trophic and habitat shifts within species that can further influence contaminant exposure. We compared contaminant bioaccumulation in four fish species, as well as two herbivorous invertebrates, from a coal combustion waste contaminated stream. Muscle, liver, and gonad tissue were analyzed from fish stratified across the broadest size ranges available. Effects of trophic position (δ (15)N), carbon sources (δ (13)C), and body size varied among and within species. Mercury and cesium concentrations were lowest in the invertebrates and increased with trophic level both among and within fish species. Other elements, such as vanadium, cadmium, barium, nickel, and lead, had greater levels in herbivorous invertebrates than in fish muscle. Sequestration by the fish livers averted accumulation in muscle. Consequently, fish liver tissue appeared to be a more sensitive indicator of bioavailability, but exceptions existed. Despite liver sequestration, within fishes, muscle concentrations of many elements still tended to increase by trophic level. Notable variation within some species was observed. These results illustrate the utility of stable isotope data in exploring differences of bioaccumulation within taxa. Our analyses suggest a need for further evaluation of the underlying sources of this variability to better understand contaminant bioaccumulation in large predatory fishes.
