This data release includes physical and chemical characteristics of field collected sediment and soil samples in Missouri representing potential sediment/soil that may enter the water column during construction related activities. Three samples were collected, including Spring River sediment, Osage River bank soil and Columbia crushed limestone. The impacts of increased suspended solid level due to the three samples on early-stage freshwater mussels were examined using three freshwater mussel species, including Fatmucket (Lampsilis siliquoidea), Arkansas Brokenray (Lampsilis reeveiana), and Washboard (Megalonaias nervosa). Specifically, toxicity endpoints including survival, biomass, and growth of juveniles were...

Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute toxicity tests with pyrethroid pesticides. Exposure and recovery water quality data are also included for quality assurance purposes.
The vernal pool fairy shrimp, Branchinecta lynchi, (Branchiopoda; Anostraca) and other fairy shrimp species have been listed as ‘threatened’ or ‘endangered’ under the United States’ Endangered Species Act (ESA). There is little information about the sensitivity of Branchinecta spp. to toxic effects of contaminants, making it difficult to determine whether they are adequately protected by water quality criteria. A series of acute (24 hr) lethality/immobilization tests were conducted with three species of fairy shrimp (Branchinecta lynchi, Branchinecta lindahli, and Thamnocephalus platyurus) and 10 chemicals with varying modes of toxic action: ammonia, potassium, chloride, sulfate, chromium(VI), copper, nickel, zinc,...

These data consists of three related tables describing in-situ field conditions including pesticide concentration, water quality, and post-treatment survival of crayfish 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,...

In order to estimate the costs of chemical control of non-indigenous crayfish versus the cost of manual inspection of fish hatchery shipments a cost analysis was performed. The data includes ranking the likelihood of missing non-indigenous crayfish and effects on fish of handling during manual searches and the effects on fish during chemical exposure. The data also includes estimates of the time, staff, and salary requirements and cost of materials for each approach.

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...

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.

Physiological endpoints observed in adult largemouth bass in response to an EE2 (17 alpha-ethinylestradiol) or mixture of estrone and atrazine exposure under laboratory pond conditions. Also included are water quality and chemical concentration data. Adult LMB were exposed in outdoor pond mesocosms from post-spawning to early gonad recrudescence to either EE2 (2.4 nanograms per liter), or a mixture of endocrine-active substances commonly detected in the Chesapeake Bay watershed, atrazine (5.4 micrograms per liter) and estrone (47.9 nanograms per liter). Male reproductive condition, sperm count, and sperm motility were assessed.

We determined the acute toxicity of four wildland fire retardants (Phos-Chek 259-Fx, Phos-Chek MVP-Fx, and Phos-Chek LC-95A-Fx, and Phos-Chek LC-95A-R) to two life stages (swim-up fry and young juveniles) of rainbow trout in standardized hard and soft water. The measure of acute toxicity was expressed as both the 96-hour median lethal concentration (96-h LC50, based on mortality) and 96-h median effective concentration (EC50, based on mortality, plus loss of equilibrium and immobilization), which are statistically derived concentrations expected to kill or kill and severely impair, respectively, 50 percent of the test fish in 96 hours. This data set includes the concentration-response data at 24, 48, 72, and 96...

During 2013-2017, the U.S. Geological Survey, National Water-Quality Assessment (NAWQA) Project, collected water samples year-round from the National Water Quality Network – Rivers and Streams (NWQN) and reported on 221 pesticides at 72 sites across the US in agricultural, developed, and mixed land use watersheds. Pesticide Toxicity Index (PTI) scores, a screening-level tool that uses an additive, toxic-unit model, were calculated to estimate the potential chronic and acute toxicity to 3 taxonomic groups – fish, cladocerans, and benthic invertebrates. The pesticide that makes the single largest (maximum) contribution to the PTI is called TUmax. This dataset consists of the PTI and TUmax scores, as well as, the TUmax...
