Factors Affecting Mercury Concentrations in Iowa Fishes

Duration

June 2014 - December 2016

Narrative

Goals and Objectives:
- Develop regression models to predict the concentration of mercury in a range of fishes as a function of fish total length across natural lakes, impoundments, reservoirs, and rivers to guide consumption advisories.
- Evaluate regional (e.g., north vs south, east vs west) differences in mercury concentrations to help guide consumption advisories. Include additional biotic (e.g., age, food web dynamics) and abiotic (e.g. land use, water quality) factors in models to explain additional variation in mercury concentration not explained by fish length.
- Evaluate temporal changes in mercury concentrations in largemouth bass to guide mercury sampling protocols.
