Effects of experimental thermocline and oxycline deepening on methylmercury bioaccumulation in a Canadian Shield lake
(American Chemical Society, 2014-02-10)
Environmental disturbances like deforestation or climate change may influence lake thermal and oxic stratification, thereby modifying cycles of contaminants such as mercury (Hg). In a lake naturally separated into three ...
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 ...
High methylmercury in Arctic and subarctic ponds is related to nutrient levels in the warming eastern Canadian Arctic
(2015-06)
Permafrost thaw ponds are ubiquitous in the eastern
Canadian Arctic, yet little information exists on their potential as
sources of methylmercury (MeHg) to freshwaters. They are
microbially active and conducive to ...
