An Ecologically Framed Mercury Survey of Finfish of the Lower Chesapeake Bay
TLDR
The SAS mixed procedure identified significant positive intraspecies relationships between MHg concentration and δ13C for summer flounder, weakfish, American eel, Atlantic croaker, and spot and suggested that trophic position but not dietary carbon source is a dominant determinant.

TLDR
It is concluded that the approximately 30 % higher average precipitation at HD01 and roughly equal PWM concentrations lead to the higher deposition at HD 01 versus OA02, and may offer scientists and modelers additional understanding of the depositional fluxes in the lower latitudes of North America.
Assessment of mitochondrial DNA damage in little brown bats (Myotis lucifugus) collected near a mercury-contaminated river
TLDR
Levels of mtDNA damage exhibited weak correlations with fur and blood THg levels, suggesting that other factors may play a role in the site-specific differences, and mtDNA is a useful biomarker in chronically exposed organisms.
Mercury Exposure as a Function of Fish Consumption in Two Asian Communities in Coastal Virginia, USA

TLDR
The greater seafood and mercury ingestion rates of studied Asian groups compared with non-Asian groups suggest the need for specific seafood consumption advice for ethnic communities in the United States.
The Challenge and Its Solution When Determining Biogeochemically Reactive Inorganic Mercury (RHg): Getting the Analytical Method Right
Biogeochemially reactive inorganic mercury (RHg) is an important fraction of Hg. Researchers have attempted to measure RHg when characterizing Hg-impacted sites, conducting research and development

TLDR
Trophic models based on delta(15)N were adequate for predicting changes in mercury concentrations in edible fish under different remediation scenarios.

Mercury cycling in stream ecosystems. 3. Trophic dynamics and methylmercury bioaccumulation.
TLDR
Hg contamination in top predatorfish in streams likely is dominated by the amount of MeHg available for uptake at the base of the food web rather than by differences in the trophic position of top predator fish.

Patterns and Interpretation of Mercury Exposure in Freshwater Avian Communities in Northeastern North America
TLDR
Differences in Hg exposure among species are primarily correlated with trophic position and availability of MeHg, and those among species exhibiting sexual dimorphism and niche partitioning are of interpretive concern.

Adverse effects from environmental mercury loads on breeding common loons
TLDR
The common loon is used as an upper trophic level bioindicator of aquatic Hg toxicity in freshwater lakes to measure significant changes related to elevated MeHg body burdens, including aberrant incubation behavior, lethargy, and wing area asymmetry.

TLDR
Instantaneous concentrations of filtered total mercury (FTHg) and filtered methylmercury (FMeHg) exhibited strong positive correlations with both dissolved organic carbon (DOC) concentrations and streamflow for most streams, whereas mean FTHg and MeHg concentrations were correlated with wetland density of the basins.
