Abstract Widespread mercury (Hg) contamination of freshwater systems, due primarily to deposition atmospheric inorganic Hg (IHg), poses a potential threat recreational fisheries. In aquatic ecosystems, IHg is converted by bacteria methylmercury (MeHg), potent toxin that bioaccumulates in consumers and biomagnifies through the food web, reaching elevated concentrations fish. Methylmercury has concentration‐dependent sublethal effects on fish, including reductions reproductive output. present study, we conducted first analysis health risks MeHg largemouth bass ( Micropterus salmoides ), popular game southeastern United States. To assess risk posed bass, compared three sizes adult benchmarks associated with onset adverse We also determined how varied spatially throughout Our study suggests States may be detrimental fisheries this economically important species Environ Toxicol Chem 2023;42:1755–1762. © 2023 The Authors.
