Little is known about the underlying mechanisms governing uranium (U) bioaccumulation in aquatic insects, especially the influence of surface adsorption on the measured U concentrations (Henry et al. 2020). U.S. Geological Survey scientists are conducting experiments to parameterize conditional rate constants for aqueous U uptake and to quantify desorption of weakly bound U from insect's integument. Henry, Brianna L., Marie-Noële Croteau, David M. Walters, Janet L. Miller, Daniel J. Cain, and Christopher C. Fuller. Uranium bioaccumulation dynamics in the mayfly Neocloeon triangulifer and application to site-specific prediction. Environmental Science & Technology 54, no. 18 (2020): 11313-11321.

Arsenic (As) toxicity is a global environmental and health problem. There are both natural (eg volcanic activity) and anthropogenic sources of As (eg lead arsenate and copper arsenate were commonly used pesticides in the 1900’s). Aqueous levels of arsenic in the Klamath Basin (CA, OR), which has a volcanic origin, can exceed at some locations both the Oregon Department of Environmental Quality human health water quality criteria (2.1 ug/L) (Sturdevant, 2011) and the US EPA drinking water limit (10 ug/L) (US EPA., 2001). In this study, dissolved concentrations of As, copper (Cu) and lead (Pb) were measured in more than 30 sites within the Klamath Basin between May and October. Results from samples collected between...

This data release includes sampling location data, laboratory processed surface water chemistry data (anions, cations, total nitrogen, dissolved organic carbon, deuterium, trace metals), laboratory processed pore water chemistry data (anions, cations, total nitrogen, dissolved organic carbon, trace metals), laboratory process sediment data (trace metals), and whole-body trace metal concentrations plus stable isotope values (carbon, nitrogen, deuterium) for larval aquatic insects, emergent adult insects, and two riparian spider families from Torch Lake and Gratiot Lake (N=3 sites at each lake). Torch Lake (Houghton County, Keweenaw Peninsula, Michigan, USA) is a Great Lakes Area of Concern (AOC) owing to a high concentration...

Data collected in a series of laboratory experiments conducted with juvenile freshwater snails (Lymnaea stagnalis) reared in the laboratory and exposed to dissolved platinum (Pt), or polyvinylpyrrolidone coated platinum nanoparticles (PtNPs) of five different nominal hydrodynamic diameters in the presence (or absence) of natural organic matter (NOM) are presented in this data release. Files include 1) a data dictionary describing the variables; 2) exposure characteristics of the experimental solutions; 3) Pt concentrations in the experimental organisms; and 4) QA/QC performed during the analysis. Format of the files is comma delimited (*.csv). .

Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana (MT), as part of a long-term monitoring program within the Upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the Upper Clark Fork Basin and monitor trace elements associated with historical mining and smelting activities. Sampling sites were on the Clark Fork River and a subset of its tributaries. Water samples were collected periodically at 21 sites from October 2020 through September 2021. Bed-sediment and tissue samples were collected once at 13 sites in July 2021. Water-quality...
