Date published or finalized for release: 2022-08-26 4. Date of data collection (single date, range, approximate date): 2016-2018 5. Geographic location of data collection (where was data collected?): Minnesota, USA 6. Information about funding sources that supported the collection of the data: This study was funded by the University of Minnesota (UMN) College of Veterinary Medicine's Population Signature Program, UMN Agriculture Experiment Station Research Funds (MN-62-062), UMN MnDRIVE Global Food Ventures, UMN Informatics Institute MnDRIVE, the Environmental Protection Agency's Great Lakes Restoration Initiative, and the Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources (M.L. 2017, Chp. 96, Sec. 2, Subd 04g). 7. Overview of the data (abstract): 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. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

Sensitivity analysis for changes in fish chemicals priority level based on detection frequency thresholds -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Samples were taken from 2016 in two regions of northeastern Minnesota, the Grand Portage Indian Reservation and the 1854 Ceded Territory. We sampled water, sediment, and fish at sites categorized by anthropogenic pressure: wastewater effluent-impacted, developed, and undeveloped. The data from these collections were used along with some public databases to prioritize detected contaminants of emerging concern. 2. Methods for processing the data: The detected concentrations from each site were combined and used to compare to tested and predicted characteristics related to acute toxicity, endocrine activity, and physicochemical properties to screen and prioritize detected contaminants based on their potential environmental hazard.
