Compilation of contaminant of emerging concern concentrations (1991 - 2021) and associated hazard scores for assessment of potential hazard to fish in the Great Lakes Basin

This data release contains concentration and hazard score data for 16 contaminants of emerging concern (CECs) collected from surface waters throughout the Great Lakes basin. Concentration data were compiled from various online, published, or internal sources. Original data represent work conducted by federal, state, and local entities over a span of 30 years (1991 - 2021). Hazard scores for specific CECs were determined by comparing measured environmental concentrations against effect category-specific screening values. These data are supplemental information for the associated journal paper.
