Mercury (Hg) in the form of highly toxic methyl mercury (MeHg) accumulates in aquatic food webs to an extent where it may threaten fish health in many freshwaters. Selenium (Se) mitigates the toxicity of accumulated Hg by forming strong bonds with it

Recent studies report trends of strongly increasing iron (Fe) concentrations in freshwaters. Since Fe is a key element with a decisive role in the biogeochemical cycling of major elements, it is important to understand the mechanisms behind these tre

Over a one-year study period (2003), we monitored total Hg (HgT) and methyl Hg (MeHg) at two sites in a Swedish forest stream located above (Site(ref)) and below a stretch of Hg-contaminated sediments (Site(Hg)). We also monitored HgT, MeHg, and anci

Linking Cellulose Fiber Sediment Methyl Mercury Levels to Organic Matter Decay and Major Element Composition

Autor: Mark Elert, Anna Helena Falk, Lars Olof Höglund, Anders Svensson, Olof Regnell

Methylation of mercury (Hg) to highly toxic methyl Hg (MeHg), a process known to occur when organic matter (OM) decomposition leads to anoxia, is considered a worldwide threat to aquatic ecosystems and human health. We measured temporal and spatial v

Factors controlling temporal variation in methyl mercury levels in sediment and water in a seasonally stratified lake

Autor: Olof Regnell, Elsmari Lord, Göran Ewald

Total mercury (total Hg) levels were low in the water (2.5-7.5 pM) and in the sediment (150-300 pmol g (DW)-'), indicating an absence of significant local sources of Hg. During summer stratification, methyl mercury (MeHg) levels increased below the t
