Mercury contamination of aquatic ecosystems is responsible for X% of all fish consumption advisories in the United States (cite), and negatively effects beneficial uses and ecological health of aquatic resources globally (cite). The global prevalence of Hg contamination is at least partially attributable to the 3-5 fold increase in atmospheric Hg concentrations over the past 150 years associated with fossil fuel combustion (cite), as well as regional and local releases from mining and industrial applications. However, temporal patterns of Hg concentrations fish and aquatic birds that are consistent with the increases documented in abiotic matrices have not been realized. Instead, a range of trends have been detected, including increases (cite),
