Adult fathead minnows were exposed to dilutions of a historically estrogenic wastewater treatment plant effluent in a 21-d reproduction study. This dataset is comprised of a variety of endpoints representing key events along adverse outcome pathways linking estrogen receptor activation and other molecular initiating events to reproductive impairment. This study demonstrates the value of using an integrative approach that encompasses analytical chemistry, in vitro bioassays, and in vivo apical and pathway-based approaches with endpoints spanning from molecular- (e.g., gene expression) to organismal- (e.g., reproduction) levels of biological organization to help infer causal relationships between chemistry and potential effects on reproduction.

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 POCIS samples were deployed over this time of which 77% had EEQ above the limit of detection.. The maximum estrogen equivalents (EEQ) measured was 12 ng EEQ/ POCIS.

This data set describes experiments that were conducted to investigate whether exposure of male fathead minnows to environmentally-relevant estrone concentrations would result in elevated plasma 17β-estradiol concentrations in the fish. Secondly, we sought to establish whether observed elevations in plasma 17β-estradiol occurred as a result of the conversion of external estrone by the fish using an approach involving exposure of the fish to 13C-labeled estrone. Endpoints reported in the dataset include plasma 17β-estradiol and estrone concentrations, plasma vitellogenin concentrations, hepatic vitellogenin mRNA, 13C-labeled plasma 17β-estradiol and estrone concentrations, and testicular and/or hepatic expression of aromatase and several hydroxysteroid dehydrogenases involved in estrone metabolism.

This data release presents chemical and biological results from investigations of water quality, fish endocrine disruption, and emergent insects in the Shenandoah River Watershed (Virginia and West Virginia, USA) conducted during 2014, 2015, and 2016. Multiple sampling campaigns were conducted at sites located throughout the Shenandoah River Watershed (Table 1). The complex inorganic and organic chemical characteristics of river waters and wastewater treatment plant effluents were characterized using 21 separate analytical methods at 7 laboratories (Tables 2, 3, and 4). To assess the relations between water composition and fish endocrine disruption, 21-day mobile laboratory adult fathead minnow exposure experiments with water quality and biological characterization (water collected on day 0, 7, 14, and 21; fish collected on day 0, 7, and 21) were conducted at 4 locations from August 12 to September 1, 2014, 3 locations from May 26 to June 16, 2015, and 5 locations from July 27 to August 17, 2016 (Tables 1 and 5). To assess changes in water chemistry resulting from point and non-point sources along the flow path, targeted stream-reach sampling for water quality characterization was conducted at 14 locations from August 25 to August 27, 2015 (Tables 1 and 6). Temporal variability was assessed by time-series sampling for water quality characterization at 2 locations associated with wild fish collection from April 4 to June 14, 2016 (Tables 1 and 7). Spatial variability across the watershed was assessed by landscape-directed sampling for water-quality characterization with biological assessment at 18 locations from August 9 to August 16, 2016, and 17 locations from October 17 to October 18, 2016 (Tables 1 and 8). Biological results for the 21-day mobile-laboratory adult fathead minnow exposure experiments are presented in Table 9. Biological results for the wild smallmouth bass and white sucker sampling on April 12, 2016 are presented in Table 10. Biological results for the 96-hour larval fathead minnow exposures from July, August, and October 2016 are presented in Table 11. Results for tissue analysis of pesticides and disinfection byproducts in adult fathead minnows collected at day 21 of the August to September 2014 exposure experiments are presented in Table 12. Emergent aquatic insects, terrestrial insects, and spider sampling was conducted at 4 locations from May 21 to May 25, 2015 (Tables 13, 14, and 15) and tissue samples analyzed for pesticides (Tables 16 and 17).

Intersex in small- and largemouth bass has been observed in the upper Chesapeake Bay Watershed since 2003. 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 shed collected between 2008 and 2011.
