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 samples were collected during this time of which 41% had EEQ above the limit of detection. The maximum estrogen equivalents (EEQ) measured was 5.44 ng EEQ/ L, while the median concentration was 0.44 ng/L. POCIS samplers were deployed at a number of sites to determine time-weighted estrogenicity between 2014 and 2017. A total of 150...

This dataset identifies positive or negative test results for qRT-PCR (quantitative reverse transcriptase polymerase chain reaction) for avian influenza virus through identification of the Type A influenza virus matrix gene from aquatic sediment samples. Sediment samples were collected from waterfowl habitat so as to determine if temporal and spatial differences in virus detection by qRT-PCR were evident among test sites.

DNA was extracted from tumor biopsies from green sea turtles (Chelonias mydas) with fibropapillomatosis sampled from Florida and Hawaii coastal waters. We used high-throughput short-read sequencing (Illumina MiSeq and Ion Torrent Personal Genome Machine) of long-range PCR products amplified from tumor tissue using primers designed from the single available ChHV5 reference genome from a Hawaii green sea turtle. The raw sequence data is available at the NCBI Sequence Read Archive under bioproject number PRJNA360405, including...

Occurrence of synthetic and natural hormones from wastewater treatment plants and livestock operations, pesticides from agricultural lands, and phytoestrogens from cover crops have been implicated as potential causes of these adverse effects. Late summer to fall is the period of early gonad recrudescence in adult bass when spermatogenesis and oogenesis begin for the upcoming spawning event in spring. Our objective was to assess whether early gonad recrudescence was a period of sensitivity for inducing immunomodulation. Adult largemouth bass (LMB; Micropterus...

This observation is indicative of exposure to estrogenic endocrine disrupting chemicals. In order to complement biological data sets and better identify the spatial and temporal nature of this end-point, discrete grab water samples were collected throughout the upper Chesapeake Bay Watershed for the evaluation of estrogenic activity. Data reported here are estrogenicity values derived from bioassay screening of OASIS-HLB extracts discrete grab water samples. Estrogenicity was determined using a bioluminescent yeast estrogen screen. Here we report estrogenicity data for selected sites in the Chesapeake Bay water...
