Estrogen equivalents of surface water in Pennsylvania, 2012-2017 Estrogen equivalents of surface water in Pennsylvania, 2012-2017
The data were gathered as part of a long-term, seasonal assessment of estrogenicity in selected locations within Pennsylvania from 2012-2017. Data were collected over this time frame to determine seasonal and annual changes in surface water estrogenicity.Estrogen is reported as estrogen equivalents (EEQ) as determined by a bioluminescent yeast estrogen screen. A total of 193 grab water...
Data supporting: Draft Genome Sequence of a Novel Calicivirus from a Brown Bullhead (Ameiurus nebulosus) from Lake Memphremagog, VT Data supporting: Draft Genome Sequence of a Novel Calicivirus from a Brown Bullhead (Ameiurus nebulosus) from Lake Memphremagog, VT
We report a draft genome of a previously undescribed calicivirus from a single brown bullhead inhabiting Lake Memphremagog, Vermont/Quebec. The genome is 7413 nt in length and is most similar to the Atlantic salmon calicivirus (nucleotide identity: 64.7%).

The data include concentrations of current use pesticides in tissues of larval wood frog (Lithobates sylvaticus) and spotted salamander (Ambystoma maculatum) and the presence of ranavirus in wood frogs and spotted salamanders from three northeastern National Wildlife Refuges sampled in 2013 and 2014. The data also include estrogenicity, protein phosphatase 2A inhibition and a suite of 15...
Water-quality data for a pharmaceutical study at Muddy Creek in North Liberty and Coralville, Iowa, 2017-2018 Water-quality data for a pharmaceutical study at Muddy Creek in North Liberty and Coralville, Iowa, 2017-2018
Samples were collected, processed, and analyzed for organics, estrogen equivalents, and fecal indicator bacteria. Filtered organic samples were sent to the National Water Quality Laboratory in Denver, Colorado. Unfiltered estrogen equivalent samples were sent to the Organic Geochemistry Research Lab in Lawrence, Kansas, for extraction, after which they were sent to the National Fish...
2004-2010 Chesapeake Bay Smallmouth and Largemouth Bass Estrogenic Biomarker Data 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...
Estrogen equivalents of surface water and smallmouth bass estrogenic biomarker data in New Jersey, 2016-2017 Estrogen equivalents of surface water and smallmouth bass estrogenic biomarker data in New Jersey, 2016-2017
The data were gathered as a preliminary assessment of estrogenicity under base-flow conditions at over 100 sites (lakes and streams) throughout New Jersey followed by more targeted sampling of smallmouth bass at nine sites with varying levels of estrogenicity. In 2016, 102 sites (lakes and streams) for the preliminary estrogenicity assessment were selected utilizing compiled results of...

Using biological responses to monitor freshwater post-spill conditions over 3 years in Blacktail Creek, North Dakota, USA Using biological responses to monitor freshwater post-spill conditions over 3 years in Blacktail Creek, North Dakota, USA
A pipeline carrying unconventional oil and gas (OG) wastewater spilled approximately 11 million liters of wastewater into Blacktail Creek, North Dakota, USA. Flow of the mix of stream water and wastewater down the channel resulted in storage of contaminants in the hyporheic zone and along the banks, providing a long-term source of wastewater constituents to the stream. A multi-level...

RNA-seq reveals potential gene biomarkers in fathead minnows (Pimephales promelas) for exposure to treated wastewater effluent RNA-seq reveals potential gene biomarkers in fathead minnows (Pimephales promelas) for exposure to treated wastewater effluent
Discharged wastewater treatment plant (WWTP) effluent greatly contributes to the generation of complex mixtures of contaminants of emerging concern (CECs) in aquatic environments which often contain neuropharmaceuticals and other emerging contaminants that may impact neurological function. However, there is a paucity of knowledge on the neurological impacts of these exposures to aquatic...

Freshwater unionid mussels threatened by predation of Round Goby (Neogobius melanostomus) Freshwater unionid mussels threatened by predation of Round Goby (Neogobius melanostomus)
Indigenous freshwater mussels (Unionidae) are integral to riverine ecosystems, playing a pivotal role in aquatic food webs and providing ecological services. With populations on the decline worldwide, freshwater mussels are of conservation concern. In this study, we explore the propensity of the invasive Round Goby (Neogobius melanostomus) fish to prey upon indigenous freshwater mussels...

Site- and individual-level contaminations affect infection prevalence of an emerging infectious disease of amphibians Site- and individual-level contaminations affect infection prevalence of an emerging infectious disease of amphibians
Emerging infectious disease outbreaks are one of multiple stressors responsible for amphibian declines globally. In the northeastern United States, ranaviral diseases are prevalent in amphibians and other ectothermic species, but there is still uncertainty as to whether their presence is leading to population level effects. Further, there is also uncertainty surrounding the potential...

Tandem field and laboratory approaches to quantify attenuation mechanisms of pharmaceutical and pharmaceutical transformation products in a wastewater effluent-dominated stream Tandem field and laboratory approaches to quantify attenuation mechanisms of pharmaceutical and pharmaceutical transformation products in a wastewater effluent-dominated stream
Evolving complex mixtures of pharmaceuticals and transformation products in effluent-dominated streams pose potential impacts to aquatic species; thus, understanding the attenuation dynamics in the field and characterizing the prominent attenuation mechanisms of pharmaceuticals and their transformation products (TPs) is critical for hazard assessments. Herein, we determined the...
