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...

This data release includes data from laboratory bioassay sediment exposures to Lampsilis siliquoidea and Hyallela azteca. Sediment was collected from streams and rivers within the Tri-State Mining District (TSMD). Endpoints include survival, reproduction and growth, metal concentrations, and various water quality parameters collected during the exposures

Data collected from acute 96-hour and chronic 28-day toxicity tests of Aluminum to a commonly tested unionid mussel (Lampsilis siliquoidea) and a commonly tested amphipod (Hyalella azteca) at a pH of 6 and water hardness of 100 mg/L as CaCO3.

This data release includes physical and chemical characteristics of field collected samples from streams and rivers within the Tri-State Mining District (TSMD) as well as toxicity endpoints from chronic water-only and sediment laboratory exposures including survival and growth of the mussel Lampsilis siliquoidea; survival, growth, and reproduction of the amphipod Hyalella azteca; metal concentrations, and various water quality parameters collected during the toxicity studies. Mining in the Tri-State Mining District took place over a large geographic area, with mining taking place in the three states of Missouri, Kansas, and Oklahoma.

Chronic (28-d) toxicity of 4-nonylphenol (4-NP) to two commonly tested species of mussels: fatmucket (Lampsilis siliquoidea) and rainbow mussel (Villosa iris).

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.

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.

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...
