Data on the acute and chronic toxicity of sodium chloride and sodium sulfate to freshwater organisms in a low hardness water representing Louisiana water conditions
We determined acute and chronic toxicity of sodium chloride (NaCl) and sodium sulfate (Na2SO4) to up to 7 freshwater species of different taxa in a hardness water of 40 mg/L as CaCO3 and evaluated the effect of 4 hardness waters (15, 30, 60, and 120 mg/L as CaCO3) on acute toxicity of NaCl and Na2SO4 to 3 sensitive species tested in the acute exposures. This data release reports results from acute

Dataset consists of 4-day, 14-day, and full life responses of laboratory cultured mayflies (Neocloeon triangulifer) to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Responses were measured as survival at 4 days, 14 days, pre-emergent nymph (PEN) stage, and emergence; 14-day length; number of days to PEN stage, and imago live weight.

Survival, growth, and chemical data from a study on influences of water hardness on chronic toxicity of potassium chloride to a Unionid mussel (Lampsilis siliquoidea)
The objective of this study was to evaluate the chronic toxicity of potassium (tested as KCl) to a commonly tested unionid mussel (fatmucket, Lampsilis siliquoidea) at five water hardness levels (25, 50, 100, 200, 300 mg/L as CaCO3) representing most surface waters in the United States. Chronic 28-d potassium chloride toxicity tests were conducted with 3-week-old juvenile fatmucket using six conc

Bottom sediment chemical data at rivermouths and harbors along western Lake Michigan, USA, 2016
Streambed sediment samples were collected in October 2016 from streams tributary to Wisconsin?s western Lake Michigan shoreline. Streams included two Areas of Concern (AOCs), two non-AOC comparisons, and two additional non-AOC study areas. Within the Milwaukee Estuary AOC, samples were collected from the Milwaukee River (three subsites), the Menomonee River (two subsites), the Kinnickinnic River (

Bioaccumulation kinetics of model pharmaceuticals in the freshwater unionid pondmussel, Sagittunio subrostratus
Bioaccumulation of ionizable pharmaceuticals has been increasingly studied, with most reported aquatic tissue concentrations in field or laboratory experiments being from fish. However, higher levels of antidepressants have been observed in bivalves compared with fish from effluent-dominated and dependent surface waters. Such observations may be important for biodiversity because approximately 70%

Laboratory-derived bioaccumulation kinetic parameters for four per- and polyfluoroalkyl substances in freshwater mussels
Although freshwater mussels are imperiled and identified as key conservation priorities, limited bioaccumulation information is available on these organisms for contaminants of emerging concern. In the present study we investigated the bioaccumulation of per- and polyfluoroalkyl substances (PFAS) in the model freshwater pond mussel Sagittunio subrostratus because mussels provide important ecosyste

Perfluorooctanesulfonate adversely affects a mayfly (Neocloeon triangulifer) at environmentally realistic concentrations
Of the emerging contaminant types thought to threaten freshwater biota, per- and polyfluoroalkyl substances appear to be particularly widespread, and limited studies conducted with these compounds thus far indicate insects may be particularly sensitive to them. This study investigated the short- and long-term effects of two commonly detected compounds on the laboratory-reared mayfly Neocloeon tria

Influences of water hardness on chronic toxicity of potassium chloride to a unionid mussel (Lampsilis siliquoidea)
Elevated concentrations of potassium (K) often occur in effluents from wastewater treatment plants, oil and gas production operations, mineral extraction processes, and from other anthropogenic sources. Previous studies have demonstrated that freshwater mussels are highly sensitive to K in acute and chronic exposures, and acute toxicity of K decreases with increasing water hardness. However, littl

Lethal impacts of selenium counterbalance the potential reduction in mercury bioaccumulation for freshwater organisms☆
Mercury (Hg), a potent neurotoxic element, can biomagnify through food webs once converted into methylmercury (MeHg). Some studies have found that selenium (Se) exposure may reduce MeHg bioaccumulation and toxicity, though this pattern is not universal. Se itself can also be toxic at elevated levels. We experimentally manipulated the relative concentrations of dietary MeHg and Se (as selenomethion

Acute and chronic toxicity of sodium nitrate and sodium sulfate to several freshwater organisms in water-only exposures
Elevated nitrate (NO3) and sulfate (SO4) in surface water are of global concern, and studies are needed to generate toxicity data to develop environmental guideline values for NO3 and SO4.

Sensitivity of warm water fishes and rainbow trout to selected contaminants
Guidelines for developing water quality standards allow U.S. states to exclude toxicity data for the family Salmonidae (trout and salmon) when deriving guidelines for warm-water habitats. This practice reflects the belief that standards based on salmonid data may be overprotective of toxic effects on other fish taxa. In acute tests with six chemicals and eight fish species, the salmonid, Rainbow T

Freshwater mussels (order Unionoida) are one of the most imperiled groups of animals in the world. However, many ambient water quality criteria and other environmental guideline values do not include data for freshwater mussels, in part because mussel toxicity test methods are comparatively new and data may not have been available when criteria and guidelines were derived.
