“…This practice received little attention from the public until December 2008, when 4.1 million m 3 of coal ash at the Tennessee Valley Authority (TVA) Kingston Fossil Plant in Kingston, Tennessee spilled into the Emory River in the upper reaches of the Watts Bar Reservoir system [2]. Due to its association with heavy metals, coal ash is now recognized by the public as a substantial threat to drinking water, recreation, aquatic organisms and habitat [3,4]. Most of the coal ash spilled at Kingston was mechanically and hydraulically dredged, however 400,000 m 3 was mixed with legacy contaminants, primarily 137 Cs and Hg released from US Department of Energy facilities at Oak Ridge [2] and another 92,000 m 3 eroded during a flood prior to dredging [5].…”

h i g h l i g h t sKingston coal ash increases magnetic susceptibility of riverbed sediment. Fluvial transport both enriches and dilutes the magnetic fraction of coal ash. Micron-size magnetite and maghemite occur within aluminosilicate spheres. Magnetospheres dominate the magnetic signal in the Watts Bar watershed. a b s t r a c tThe magnetic properties of riverbed samples collected after the 2008 Tennessee Valley Authority (TVA) coal ash spill in Kingston, Tennessee are investigated. Coal ash persists in this fluvial environment because 400,000 m 3 of ash remains in areas that were not dredged. The magnetic fraction is low in comparison to other coal ash; 1.4 wt% in a sample from the failed ash storage cell increasing to 3.0 wt% in riverbed samples in the Emory River near the spill. Thermomagnetic analysis, XRD, SEM and polarized light microscopy identified magnetospheres with magnetite and maghemite from the Kingston coal ash as the magnetic carrier. Anthropogenic nonspherical magnetic particles are introduced from the industrialized Tennessee River watershed prior to reaching the Watts Bar Reservoir. A bivariate plot of anhysteretic remanent magnetization (ARM) versus mass-normalized low field magnetic susceptibility (v LF ) models the mixing of ash in the rivers, identifying both enrichment of magnetospheres by sorting near the spill and dilution with native sediment downstream. Concentration-dependent magnetic parameters in ash-bearing samples are approximately 2-56 times stronger than those of the ash-free watershed samples. This study supports the use of magnetic parameters to track the ash as it is eroded and transported 71 km downstream to the Watts Bar Dam and suggests that v LF can be utilized to track the migration of coal ash in other river systems.

“…Their results have shown that in some cases metal(loid)s accumulated in fish exposed to some kind of pollution (natural or anthropogenic), may jeopardize the health of the population that consume these contaminated fish [23,53,68,69]. The results of the assessment of potential health effects that may inflict the average intake of the fish species caught in the reservoir Luis L Leon are presented below.…”

Concentrations of As, Cu, Fe, Hg, Pb and Zn and activity concentrations from 234,238U and 210Po in water, fillet, liver and gills were determined in three stocked fish species from the Luis L. Leon reservoir, located in Northern Mexico. The considered species were Lepomis cyanellus, Cyprinus carpio and Ictalurus furcatus. 238U and 234U activity concentration (AC) in fillet samples showed values of 0.007–0.014 and 0.01–0.02 Bq∙kg−1 wet weight (ww), respectively. Liver samples for L. cyanellus, C. carpio and I. furcatus present 210Po AC of 1.16–3.26, 0.70–1.13 and 0.93–1.37 Bq∙kg−1 ww. Arsenic, mercury and lead concentration intervals in fillet samples were 0.13–0.39, 0.005–0.126 and 0.009–0.08 mg∙kg−1 ww, respectively, while in gill samples they were 0.11–0.43, 0.002–0.039 and 0.02–0.26 mg∙kg−1 ww. The elemental Bioaccumulation Factor (BAF) for fish tissues with respect to their concentrations in water was determined. L. cyanellus showed the highest BAF values for As and total U, being BAFAs = 37 and 40 L∙kg−1 in fillet and gills, respectively, and BAFU total = 1.5 L∙kg−1 in fillet. I. furcatus showed the highest BAF values for Hg and Pb, being BAFHg = 40 and 13 L∙kg−1 in fillet and gills, and BAFPb = 6.5 and 22 L∙kg−1 in fillet and gills, respectively. Some metal(loid) concentrations are slightly higher than European regulations for fish fillets. The difference in concentrations of metal(loid)s in fillet among the studied species is probably due to their differences in diet and habitat.

“…Previous research on the Kingston spill showed similar results for raccoons, with no spatial pattern of metal concentrations observed (Souza et al 2013). However, multiple other studies have observed significant increases, mainly in selenium and arsenic concentrations, at ash-associated sites compared to references locations in fish (Otter et al 2012) and spiders (Otter et al 2013).…”

“…Previous research on the Kingston spill has provided insight on the contaminants of concern from multiple perspectives including sediment biogeochemistry, metal speciation, and metal bioaccumulation across multiple organisms (Ruhl et al 2010;Bednar et al 2010;Ruhl et al 2009;Otter et al 2013;Deonarine et al 2013;Bartov et al 2012;Liu et al 2013;Beck et al 2013;Souza et al 2013). Otter et al (2012) showed elevated concentrations of arsenic and selenium in various tissues of multiple fish species at ash-associated sites compared to reference sites. Laboratory experiments showed elevated concentrations of arsenic, selenium, and mercury in sediment samples, but no effects on larval or juvenile fathead minnows (Pimephales promelas) when exposed to ash-amended sediment or elutriates (Stanley et al 2013;Greeley et al 2014).…”

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.
