“…Although our study showed that concentrations of the coal ash-associated contaminants As and Se were higher in all the sample matrices including snails and mayflies at ash-affected 2: Biomagnification factors (BMFs) calculated as the ratio between the average concentrations of each trace element (expressed as parts per million dry wt) in the biota (i.e., mayfly nymphs and adult snails) and the average concentration of each trace element (expressed as parts per million dry wt) in their respective food resources (i.e., sediment and periphyton) a sites than at the reference sites, major remediation activities removed much of the spilled ash from the site in 2010 and 2011; and as a result, trace element concentrations in mayfly nymphs were shown to decrease in the 4 yr following the spill (Smith et al 2016). Overall, concentrations of trace elements associated with coal ash measured in mayfly nymphs in the present study remained similar to the ones reported in mayflies in other sites (Cid et al 2010;Opfer et al 2011;Fletcher et al 2014Fletcher et al , 2017. It is always complex to address the risks associated with trace elements on aquatic biota based solely on their concentrations because many factors can significantly affect trace element bioavailability and toxicity and, therefore, the consequences on the invertebrate populations (e.g., Mathews et al 2020).…”

We examined the bioaccumulation of essential (Cu, Fe, Se, and Zn) and nonessential (As and Hg) trace elements in 2 aquatic invertebrate species (adult snails and mayfly nymphs) with different feeding habits at the site of a coal ash spill. Differences in food web pathway, exposure concentrations, and biological processing affected bioaccumulation patterns in these species. Mayflies had higher body burdens, but snails had higher retention of most elements studied.

“…Their values remained near the background levels in the basal 10-cm section (prior to 1880), increased gradually until 1950, increased rapidly between 1950 and 1970, and subsequently decreased towards the sediment-water interface. The trace metal concentrations of the core-top sediments are comparable with those measured on surficial sediments in the western basin 29 30 ( Table 1 ). Our sediment chronology is in good agreement with previously published Pb records from the central (C94) 16 and eastern (E91) 18 basins ( Figure 3 ).…”

Ecosystem regime change inferred from the distribution of trace metals in Lake Erie sediments

Many freshwater and coastal marine ecosystems across the world may have undergone an ecosystem regime change due to a combination of rising anthropogenic disturbances and regional climate change. Such a change in aquatic ecosystems is commonly seen as shifts in algal species. But considerably less detail is known about the eutrophication history in terms of changes in algal productivity, particularly for a large lake with a great deal of spatial variability. Here we present an analysis of trace metals (Cu, Ni, Cd, and Pb) on a sediment core recovered from Lake Erie, off the Vermilion coast of northern Ohio, USA, to reconstruct the eutrophication history of the lake over the past 210 years. Following a slow eutrophication during European settlement, Lake Erie experienced a period of accelerated eutrophication, leading to an ecosystem regime transition into a eutrophic lake state in 1950. Our results suggested that the lake's biological productivity has ever since maintained fairly high even though a significant input reduction was realized from rigorous nutrient abatements that began as early as in 1969. This work underscored the role of in-lake biogeochemical cycling in nutrient dynamics of this already eutrophic lake.

“…All water samples were stabilized in the field with two percent (by volume) trace-metals grade nitric acid. Unfiltered water samples were digested according to USEPA Method 3015A (Microwave-Assisted Acid Digestion of Aqueous Samples and Extracts, USEPA 2007) using a microwave system (CEM MARSXpress, CEM Corp., Matthews, NC), and a leaching technique that results in the extraction of bioavailable metals (Opfer et al 2011). Copper concentrations were determined following USEPA Method 6010C (Inductively Coupled Plasma-Atomic Emission Spectrometry, USEPA 2007) using an inductively coupled plasma optical emission spectrophotometer (ThermoElectron iCAP 6500 Inductively Coupled Plasma Optical Emission Spectrophotometer, Thermo Fisher Scientific, Inc., Waltham, MA).…”

Municipal water managers use copper sulfate (CuSO4) to control algae, predominantly phytoplankton, in water supply reservoirs. In multiple-purpose upground reservoirs in northwestern Ohio, CuSO4 application regimens vary from no application to over 600 µg Cu/L/year. Whereas CuSO4 effectively suppresses phytoplankton growth, it also has documented toxicities to zooplankton, which serve as forage for stocked sport fish. Consequently, CuSO4 application benefits one upground reservoir use (water supply) while potentially negatively affecting another (sport fishing). This research sought to directly compare copper concentrations ([Cu]) in dissolved and particulate fractions with corresponding zooplankton community composition and abundance both before and after CuSO4 application in Ohio upground reservoirs. Copper concentrations and zooplankton community characters were measured at four upground reservoirs (n = 2 treated with CuSO4 and n = 2 untreated) over multiple weeks during summer 2010. Total [Cu] in treated reservoirs increased by as much as 428% from pre- (mean = 16.5 µg/L) to post-application (mean = 70.7 µg/L); concomitantly, zooplankton biomass and density decreased by as much as 93%. Post-application zooplankton communities shifted to dominance by small copepod nauplii from a mixed community that included larger cladocerans. Copepod nauplii represent a less-suitable food source for stocked juvenile yellow perch Perca flavescens. Thus, short-term negative effects to the zooplankton community may result from CuSO4 applications, indirectly affecting stocked sport fish success.
