Effects of environmentally relevant mixtures of major ions on a freshwater mussel

Exposure to Elevated Concentrations of Major Ions Decreases Condition Index of Freshwater Mussels: Comparison of Metrics

“…A 50:50 mixture of filtered pond water:deionized water was used as the control water and as a base water to prepare the simulated Powell River water. A previous study demonstrated excellent mussel survival in the 50:50 mixture, compared to poor survival in 100% pond water when used in closed exposure systems (Ciparis et al 2015). The target TDS concentration for simulated Powell River water was 950 mg/L, similar to the target concentration for simulated Powell River water (942 mg/L) derived in Ciparis et al (2015).…”

The target TDS concentration for simulated Powell River water was 950 mg/L, similar to the target concentration for simulated Powell River water (942 mg/L) derived in Ciparis et al (2015). This represents recent TDS concentrations measured during low-flow conditions at a Virginia Department of Environmental Quality (VDEQ) longterm monitoring station on the Powell River, at Big Stone Gap, Virginia (6BPOW179.20; for location information see Fig.…”

Spatial and temporal relationships among watershed mining, water quality, and freshwater mussel status in an eastern USA river

“…Also, L. siliquoidea is not native to the Powell River. Ciparis et al (2015) tested response by juvenile Villosa iris, a Powell River native mussel, to elevated DS (N900 mg/L) with an ion composition intended to simulate the upper Powell River; no significant effects on growth or survival were found over a 55 day study period. Test concentrations were based on the highest recorded concentrations of major Fig.…”

Molecular cloning, characterization, and the response of Cu/Zn superoxide dismutase and catalase to PBDE-47 and -209 from the freshwater bivalve Anodonta woodiana

“…The Chinese pond mussel (the Eastern Asiatic freshwater clam or swanmussel), bivalve Anodonta woodiana functions as a main criteria required for a bio-indicator organism [18,19]. Earlier studies have revealed the ability of Sinanodonta woodiana to accumulate trace elements and pesticides [20,21], as well as its potential to detect genotoxicity [22]. In addition, these mussels have important ecosystem functions such as particle filtration and processing, nutrient release, and sediment mixing [23].…”
