    A major challenge in ecotoxicology is accurately and sufficiently measuring chemical exposures and biological effects given the presence of complex and dynamic contaminant mixtures in surface waters. Our study examined the performance of the Daphnia magna transcriptome to detect distinct responses across three water sources in Minnesota: laboratory [well] waters, wetland waters, or stormwaters. Pyriproxyfen (PPF) was included as a gene expression and male neonate production positive control to examine whether gene expression resulting from exposure to this well-studied juvenoid hormone analog can be detected in complex matrices. Laboratory-reared (<24 hr) D. magna were exposed to a water source and/or PPF for 16 d to monitor phenotypic changes or 96 hr to examine gene expression responses using Illumina HiSeq 2500 (10 million reads per library, 50-bp paired-end (2x50)).

    Supporting data for "A chemical prioritization process: Applications to contaminants of emerging concern in freshwater ecosystems (Phase 1)"
    (2022-09-08) Deere, Jessica R; Streets, Summer; Jankowski, Mark D; Ferrey, Mark; Chenaux-Ibrahim, Yvette; Convertino, Matteo; Isaac, E.J.; Phelps, Nicholas B.D.; Primus, Alexander; Servadio, Joseph L; Singer, Randall S; Travis, Dominic A; Moore, Seth; Wolf, Tiffany M; deere007@umn.edu; Deere, Jessica R
    These data describe contaminants of emerging concern (CECs) detected in subsistence fish species and freshwater ecosystems on the Grand Portage Indian Reservation and adjacent 1854 Ceded Territory in Northeastern Minnesota, USA. They also contain chemical-specific information, including acute toxicity, endocrine activity, physicochemical properties, and frequency of occurrence data used to prioritize detected CECs based on their potential environmental hazard.
