“…In a field study, both Se and As concentrations in largemouth bass collected from a fly ash basin were elevated in four distinct tissue types, whereas elevated levels of other trace elements were not nearly as consistent [31]. In contrast, several metals (including Se) were elevated in sunfish and minnow species collected from fly ash pond receiving streams in Ohio and West Virginia [30,33].

“…While fish collected from high-exposure settings (CR and LSC) are likely permanent residents of the fly ash impoundment receiving streams (previous studies of these streams have documented unique biochemical and hematological parameters in resident fish, e.g., [30]), there was some uncertainty in the actual long-term fly ash exposure for fish collected from BC and FC (medium-exposure sites) and the OR (low exposure).

Releases from coal ash impoundments can be a significant source of trace elements to the aquatic environment. In the present study, whole-body concentrations of As, Hg, and Se in various fish species inhabiting streams receiving a gradient of fly ash exposure are reported. High-exposure sites had elevated water concentrations of As, Mo, Se, and SO(4) . Fish were collected during two seasons in 2007. Mercury concentrations in all fish samples were low (range = 1.2-99 ng/g wet wt); highest As concentrations occurred in fish from high-exposure sites. Whole-body Se concentrations were low at reference sites but increased as the magnitude of fly exposure increased. For all sites combined, a significant (r(2) = 0.60) correlation was observed between the geometric mean of each species' whole-body Se concentration and log-transformed water Se concentration. A significant inverse relationship was apparent with log-transformed whole-body Hg and Se concentrations (r(2) = 0.56 for all species and sites combined), suggesting that high tissue Se levels antagonistically regulated Hg bioaccumulation. Sunfish (Lepomis sp.) from high- and medium-exposure sites had significantly higher Se body residues, but significantly lower Hg, relative to fish from low-exposure and reference sites. Ninety percent of fish from high-exposure sites had a surplus of Se, whereas all fish from reference sites had Se/Hg molar ratios <1.0. These ratios increased as water Se increased. Where fish have moderate to high exposure to fly ash-influenced water, Se tissue levels can be expected to be elevated (as well as As, in some cases), but tissue Hg concentrations will likely be low.

“…Selenium administration to rats with induced liver damage was shown to reduce liver damage, and interestingly, it was also demonstrated to prevent loss of liver glycogen, when compared to controls not supplemented with selenium [14]. It was reported that liver glycogen increased in fish supplemented with selenium, and this increase was parallel to selenium levels in the liver tissue [15]. By the same token, selenium, an essential element, was reported to reduce the amount of plasma glucose in rats [7].…”

There are a few of studies examining how selenium, which is known to reduce oxidative damage in exercise, influences glucose metabolism and exhaustion in physical activity. The present study aims to examine how selenium administration affects liver glycogen levels in rats subjected to acute swimming exercise. The study included 32 Sprague-Dawley type male rats, which were equally allocated to four groups: Group 1, general control; Group 2; selenium-supplemented control (6 mg/kg/day sodium selenite); Group 3, swimming control; Group 4, selenium-supplemented swimming (6 mg/kg/day sodium selenite). Liver tissue samples collected from the animals at the end of the study were fixed in 95% ethyl alcohol. From the tissue samples buried into paraffin, 5-µm cross-sections were obtained using a microtome, put on a microscope slide, and stained with PAS. Stained preparations were assessed using a Nikon Eclipse E400 light microscope. All images obtained with the light microscope were transferred to a PC and evaluated using Clemex PE 3.5 image analysis software. The highest liver glycogen levels were found in groups 1 and 2 (p < 0.05). The levels in group 4 were lower than those in groups 1 and 2 but higher than the levels in group 3 (p < 0.05). The lowest liver glycogen levels were obtained in group 3 (p < 0.05). Results of the study indicate that liver glycogen levels that decrease in acute swimming exercise can be restored by selenium administration. It can be argued that physiological doses of selenium administration can contribute to performance.

“…Previous research investigating the effects of coal-ash-associated metals on aquatic organisms have focused primarily on areas receiving coal ash effluent (Reash et al 2006;Baumann and Gillespie 1986;Lohner et al 2001) and not from an environmental spill, as was the case in this study. As unfortunate as the spill was, it provided an opportunity to directly study the impact of coal fly ash in a large lotic system where the amount of downstream transport of ash was also being investigated and monitored (TVA 2010b).…”

On December 22, 2008, a dike containing coal fly ash at the Tennessee Valley Authority Kingston Fossil Plant (TN, USA) failed, and within months, dredging operations began to remove ash-contaminated sediments. The purpose of this study was to investigate differences in the bioaccumulation of metals in three mussel species during and after dredging operations. Mussels were caged for approximately 1 year during dredging and after, and then mussel condition index values and As, Cd, Cr, Pb, Ni, Se, Hg, U, Fe, Mg, Al, Sb, Ba, Be, Co, Cu, Mn, Mo, Ag, Sr, Tl, V, and Zn concentrations in soft tissue were determined via inductively coupled plasma-mass spectrometery. Overall, the differences observed in metal bioaccumulation and mussel health suggest that mussels in the immediate downstream area of the dredging site may have been impacted, as evidenced by a significant decrease in mussel condition index values, but that this impact did not result in increased tissue concentrations of metals.
