Factors related to fish mercury concentrations in Iowa lakes
Mercury contamination in aquatic ecosystems is a global concern due to the health risks of consuming contaminated fishes.

| description | Mercury contamination in aquatic ecosystems is a global concern due to the health risks of consuming contaminated fishes. Fish mercury concentrations are influenced by a range of biotic and abiotic factors that vary among regions, but these complex interactions are difficult to disentangle. We collected bluegill (
Lepomis macrochirus
), white and black crappie (
Pomoxis annularis
;
P. nigromaculatus
), largemouth bass (
Micropterus salmoides
), walleye (
Sander vitreus
), muskellunge (
Esox masquinongy
), and northern pike (
E. lucius
) from waterbodies throughout Iowa and analyzed them for mercury concentrations. We used land use, water chemistry, and fish characteristics to explain variation in mercury concentrations among and within systems. Mercury concentrations were generally low and undetectable ( |

Mercury concentrations were generally low and undetectable (< 0.05 mg/kg) in 43% of fish analyzed. Detected mercury concentrations were highest in largemouth bass, muskellunge, northern pike, and walleye, lowest in black and white crappie and bluegill, and positively related to fish length and age. Mean lake depth, pH, watershed area to lake area ratio, and percent of watershed as open water were positively related to fish mercury concentrations whereas lake area and percent of watershed as agriculture, developed, forested, and grassland were negatively related to mercury concentrations. Additionally, mercury concentrations were higher in shallow natural lakes compared to other lake types. Our results indicate fish mercury concentrations are lower in Iowa lakes compared to other regions. Models we developed in this study can be used to identify other waterbodies that may have elevated mercury concentrations that can guide fish mercury monitoring programs.</description><identifier>ISSN: 0167-6369</identifier><identifier>EISSN: 1573-2959</identifier><identifier>DOI: 10.1007/s10661-022-10427-8</identifier><language>eng</language><publisher>Cham: Springer International Publishing</publisher><subject>Abiotic factors ; Agriculture ; Aquatic ecosystems ; Atmospheric Protection/Air Quality Control/Air Pollution ; Bass ; Bioaccumulation ; Carnivorous animals ; Contamination ; Earth and Environmental Science ; Ecology ; Ecotoxicology ; Environment ; Environmental Management ; Environmental monitoring ; Environmental science ; Esox lucius ; Esox masquinongy ; Fish ; Freshwater fishes ; Grasslands ; Health risks ; Lakes ; Land use ; Marine fishes ; Mercury ; Mercury (metal) ; Micropterus salmoides ; Monitoring/Environmental Analysis ; Pomoxis annularis ; Sander vitreus ; Water chemistry ; Water depth ; Watersheds ; Whitefish</subject><ispartof>Environmental monitoring and assessment, 2022-10, Vol.194 (10), p.721-721, Article 721</ispartof><rights>The Author(s), under exclusive licence to Springer Nature Switzerland AG 2022.
