This data release includes data from laboratory bioassay water only exposures to Lampsilis siliquoidea. Endpoints include survival and growth, metal concentrations, and various water quality parameters collected during the exposures.
Description of Work The sensitivity of various species of freshwater mussels (Unioidea) to range of inorganic and organic chemicals has been evaluated in acute toxicity tests and the sensitivity of freshwater mussels to a range of inorganic chemicals has been evaluated in chronic toxicity tests. However, the chronic toxicity of organic chemicals has only been evaluated with a limited number of mussel species or for a limited number of organic chemicals. The objective of this study will be to evaluate methods for conducting 90-d water only exposures with juvenile mussels and conducted chronic 28-d toxicity tests with at least organic chemicals of concern and two commonly tested species of mussels (Lampsilis siliquoidea,...

These data consist of three related tables describing test conditions including pesticide concentration, water quality, and post-treatment survival of crayfish associated with laboratory studies conducted to determine 24-hr acute lethal concentrations of two pesticides containing pyrethrin or cypermethrin for two crayfish species, Procambarus clarkii and Faxonius virilis. Tests investigated whether two nominal temperatures (10 and 22 °C) and total suspended solids in water affected pesticide toxicity. Laboratory data will be used to design field treatments for open-water populations of invasive P. clarkii. Water quality monitoring during testing followed standard testing protocols and included temperature, pH, specific...
Description of Work Goal of this task is to conduct studies to determine the acute and chronic toxicity of sulfate (as sodium sulfate) to early life stages of: (1) fish (fathead minnow, Pimephales promelas), (2) snails (pond snail Lymnaea stagnalis), and (3) mussels (fatmucket, Lampsilis siliquoidea).

The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in several test waters with different water quality characteristics. In addition to the individual biological data, chemical, and water quality measurements from each toxicity test are also reported. Test organisms include unionid mussels (Lampsilis siliquoidea, Villosa iris), a midge (Chironomus dilutus), fish (rainbow trout Oncorhynchus mykiss and fathead minnow, Pimephales promelas), 2 amphibians (Hyla versicolor, Lithobates sylvaticus), and an amphipod (Hyalella azteca).
The objectives of the present study were to develop methods for propagating western pearlshell (Margaritifera falcata) for laboratory toxicity testing and evaluate acute and chronic toxicity of chromium VI [Cr (VI)] to the pearlshell and a commonly tested mussel (fatmucket, Lampsilis siliquoidea at 20°C or in association with a co-stressor of elevated temperature (27°C), zinc (50 µg Zn/L), or nitrate (35 mg NO3/L). A commonly tested invertebrate (amphipod, Hyalella azteca) was also tested in chronic exposures.

Description of Work A number of field studies have shown that mayflies (Ephemeroptera) tend to be more sensitive than other benthic macroinvertebrate taxa to elevated levels of total dissolved solids in streams impacted by mining. Until relatively recently, difficulties with culturing have precluded the use of mayflies as laboratory toxicity testing organisms; however, researchers at Stroud Water Research Center have found parthenogenic species that readily reproduce under laboratory conditions, and researchers at the US EPA EERD laboratory have developed laboratory cultured diets for mayflies that will help to move toward standardization of methods. Recent efforts at the Illinois Natural History Survey built upon...

Many fishes native to the Gila River Basin, Arizona, are on the decline with about 70 percent of the 17 fish species Federally listed as endangered or threatened. The decline has been partly attributed to the introduction of nonnative fishes that are of recreational interest such as catfish and smallmouth bass. Effective management practices are needed to control the nuisance nonnative fishes in Southwestern United States watersheds to prevent further decline of the native species and facilitate their restoration. An effective approach is the use of chemical toxicants to control the nuisance species. One chemical mixture of interest, Supaverm®, a combination of mebendazole and closantel, has been reported to show...

Locks and dams are possible management points to block the spread of invasive Asian carps in the United States. Infusion of carbon dioxide (CO2) into water is one deterrent strategy being considered at navigational structures to reduce upstream fish passage that would not directly interfere with lock and dam operations. The goal of this study was to determine lethal concentrations of CO2 to non-target species. Bluegill (Lepomis macrochirus) and Fathead minnows (Pimephales promelas) were exposed to CO2 continuously for 12 hours using a diluter system. Trials were performed on both species at target water temperatures of 5, 15, and 25°C. See related manuscript for additional details on experimental methods.
This data release includes data from four week sediment laboratory exposures to 1 and 2 month old Lampsilis siliquoidea. Sediment was collected from streams and rivers within the Tri-State Mining District (TSMD). Endpoints include survival and growth, metal concentrations, and various water quality parameters collected during the toxicity studies.
Two sets of PHREEQC input and output files are provided that illustrate the distribution of aqueous ammonium and ammonia as a function of physical (temperature) and chemical (pH and solution composition) conditions. One set of simulations calculates the distribution of aqueous ammonia and aqueous ammonium over a range of temperatures and pH values in different solution compositions. The other set of simulations illustrates how aqueous ammonia concentrations in a water body change over time owing to changes in pH and temperature, how ammonia concentrations potentially toxic to salmonids (trout and salmon) can occur owing to changes in pH and temperature, and how these changes in ammonia concentration can be calculated...

This dataset contains data of permethrin residues on adult mosquitoes and adult butterflies following their exposure to ultra-low volume (ULV) sprays containing permethrin. The dataset also contains toxicity information for permethrin; first for adult mosquitoes and adult butterflies following their exposure to the ULV sprays, and for adult mosquitoes exposed during toxicity tests to determine median lethal dose levels (LD50).

Attributes regarding the acute toxicity of sodium chloride (NaCl) and potassium chloride (KCl) to larvae (glochidia) or juveniles of a unionid mussel (fatmucket, Lampsilis siliquoidea) at various water hardness and in the presence of other major ions.
Data were collected associated with the application of a pesticide to a stormwater retention pond and burrows to suppress or eradicate an invasive crayfish species, Procambarus clarkii, in support of high-priority research developing control methods to mitigate impacts of invasive crayfish within the Great Lakes Basin. Effectiveness of the treatment was accessed using an in-situ bioassay and by measuring pesticide concentrations in water, sediment, and caged crayfish. Water quality data, including temperature, pH, specific conductance, dissolved oxygen, alkalinity, hardness, ammonia, and turbidity, in stormwater ponds was collected to evaluate whether environmental conditions may impact treatment effectiveness and...
Highway runoff has the potential to negatively impact receiving systems including stormwater retention ponds where highway particulate matter can accumulate following runoff events. Tire wear particles, which contain about 1% Zn by mass, make up approximately one-third of the vehicle derived particulates in highway runoff and therefore may serve as a stressor to organisms utilizing retention ponds as habitat. In this study, we focused on the potential contribution of tire debris to Zn accumulation by Rana sylvatica larvae and possible lethal or sublethal impacts resulting from exposure to weathered tire debris during development. Eggs and larvae were exposed to aged sediments (containing either ZnCl2 or tire particulate...
