Histopathology of American kestrels (Falco sparverius) sequentially exposed to first and second generation anticoagulant rodenticides

This dataset describes histopathological changes in liver, kidney, heart, skeletal muscle and intestine of captive American kestrels sequentially exposed to first and second generation anticoagulant rodenticides (FGAR and SGAR). The goal of the study was to determine the toxicity of sequential exposure to anticoagulant rodenticides (ARs) by evaluating FGAR-FGAR exposure (7 day chlorophacinone...

Histopathological assessment of the digestive gland of a freshwater snail (Lymnaea stagnalis) exposed to uranium

This dataset consists of measurements of the digestive gland in the freshwater snail Lymnaea stagnalis orally exposed to uranium. The objective of the study was to assess the morphological effects of uranium on the snail digestive gland by light microscopy. Laboratory-cultured L stagnalis were exposed to either synthetic or natural solid phases of uranium and a subset (6 controls and 6...

Histopathology of zebra finches (Taeniopygia guttata) exposed to 15mg/kg, 30mg/kg, or 60mg/kg clothianidin in seed or water

This dataset describes histopathological changes in liver, kidney, gonad, and spleen of zebra finches exposed to 15mg/kg, 30mg/kg or 60mg/kg clothianidin (CTD) in water or on millet seed. The goal of the project is to develop a subacute neonicotinoid toxicity model using zebra finches as a model passerine. We have completed two acute toxicity trials using CTD insecticide. Based on these...

Data for Understanding the captivity effect on invertebrate communities transplanted into an experimental stream laboratory

Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this gap, we conducted a 32-day test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival and adult emergence in controls from 4 subsequent...

Minnesota Mine Shaft Tracer Data, Lion Creek Watershed near Empire, Colorado, July-November, 2017

On July 26, 2017, a solution containing approximately 200 kilograms of dissolved sodium bromide was added to the the flooded underground shaft of the Minnesota Mine, near Empire, Colorado. This addition was conducted as part of an effort to determine the degree to which the mine shaft is hydrologically connected to a series of downgradient seeps and springs.

Fourier Transform Infrared (FTIR) screening of extracted sediments for samples collected for the Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015

Coastal communities are uniquely vulnerable to sea-level rise and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in subsequent years. The U.S. Geological Survey has developed the Sediment-Bound...

2004-2010 Chesapeake Bay Smallmouth and Largemouth Bass Estrogenic Biomarker Data

The data was gathered to document the extent and severity of biomarkers of exposure to estrogenic chemicals in smallmouth and largemouth bass. Samples were collected from 2004 through 2010 at sites in five watersheds within the Chesapeake Bay watershed. A total of 281 largemouth bass were collected from the Potomac, Susquehanna, Patuxent and Rappahannock rivers and 1,384 smallmouth bass from...
