TL;DR: A field experiment was conducted to determine the degree to which fish accumulated methylmercury (MeHg) via their food or via passive uptake from water through the gills as mentioned in this paper.

TL;DR: The data suggest that dry deposition of Hg on foliage as an aerosol or reactive gaseous Hg (RGM) species is low at ELA, a finding supported by preliminary measurements of RGM there.

TL;DR: Results suggest that DOC plays an important role in promoting the mobility, transport and bioavailability of inorganic Hg in these environments and elevated porewater concentrations in marine and brackish wetlands suggest coastal wetlands along the Gulf Coast are key sites for mercury production and may be a principal source of MeHg to foodwebs in the Gulf of Mexico.

TL;DR: It is shown that THg and MeHg loading can be extremely variable within a heterogeneous boreal landscape and that processes such as Hg photoreduction and emission from foliage should be considered when estimating dry deposition of Hg.

TL;DR: No significant relationship existed between overlying water MeHG concentrations and those in bed sediment or pore water, suggesting upstream sources of MeHg production may be more important than local streambed production as a driver of water column MeH g concentration in drainage basins that receive Hg inputs primarily from atmospheric sources.
