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 ...
Role of organic matter and microbial communities in mercury retention and methylation in sediments near run-of-river hydroelectric dams
(Elsevier, 2021-02-06)
Run-of-river power plants (RoRs) are expected to triple in number over the next decades in Canada. These struc-tures are not anticipated to considerably promote the mobilization and transport of mercury (Hg) and its ...
Mobilization and transformation of mercury across a dammed boreal river are linked to carbon processing and hydrology
(Wiley, 2020-09-22)
Reservoirs are known to accelerate the mobilization and cycling of mercury and carbon as aresult of flooding of terrestrial organic matter, which can lead to environmental concerns at local andbroader spatial scales. We ...
Environmental drivers of rare earth element bioaccumulation in freshwater zooplankton
(American Chemical Society, 2018-12-26)
Human activities have resulted in significant
release of rare earth elements (REEs) into the environment.
However, the pathways of REEs from waters and soils into
freshwater food webs remain poorly understood. Recent
studies ...
The fish or the egg : maternal transfer and subcellular partitioning of mercury and selenium in Yellow Perch (Perca flavescens)
(Elsevier, 2019-04-17)
Mercury (Hg) is a trace element of particular concern since it is ubiquitous in the environment and because its methylated form (MeHg) readily bioaccumulates and biomagnifies in food webs. This latter process leads to ...
