Understanding food web mercury accumulation through trophic transfer and carbon processing along a river affected by recent run-of-river dams
(2021-02-03)
Unlike large dams which favor methylation of Hg in flooded soils over long periods, run-of-river dams are designed to flood a limited area of soils and are therefore not expected to significantly affect mercury (Hg) cycling ...
Freshwater sample preservation for the analysis of dissolved low molecular mass thiols
(Wiley, 2017)
Low molecular mass (LMM) thiols are ubiquitous organosulfur peptides that play key roles in biogeochemical element cycling. These LMM thiols, found at low concentrations in the water column, are highly sensitive to oxidation ...
Relationship between extracellular low-molecular-weight thiols and mercury species in natural lake periphytic biofilms
(American chemical Society, 2015-05-26)
The uptake of mercury by microorganisms is a key step in the production of methylmercury, a biomagnifiable toxin. Mercury complexation by low molecular weight (LMW) thiols can affect its bioavailability and thus the ...
