Mercury (Hg) is a global pollutant released from both natural and human sources. Here we compare long-term records of wet deposition loadings of total Hg (THg) in the open to dry deposition loadings of THg in throughfall and litterfall under four bor

Experimental evidence for recovery of mercury-contaminated fish populations

Publikováno v: Nature

Anthropogenic releases of mercury (Hg)1–3 are a human health issue4 because the potent toxicant methylmercury (MeHg), formed primarily by microbial methylation of inorganic Hg in aquatic ecosystems, bioaccumulates to high concentrations in fish con

Although there is now a general consensus among mercury (Hg) biogeochemists that increased atmospheric inputs of inorganic Hg(II) to lakes and watersheds can result in increased methylmercury (MeHg) concentrations in fish, researchers still lack kine

Whole-ecosystem study shows rapid fish-mercury response to changes in mercury deposition

Publikováno v: Proceedings of the National Academy of Sciences. 104:16586-16591

Methylmercury contamination of fisheries from centuries of industrial atmospheric emissions negatively impacts humans and wildlife worldwide. The response of fish methylmercury concentrations to changes in mercury deposition has been difficult to est

Bioaccumulation of newly deposited mercury by fish and invertebrates: an enclosure study using stable mercury isotopes

Autor: Cheryl L. Podemski, Holger Hintelmann, John W. M. Rudd, Nives Ogrinc, Michael J. Paterson, R. Harris, Cynthia C. Gilmour, Paul J. Blanchfield, Ken A. Sandilands

Enriched stable mercury (Hg) isotopes were added to four 10 m diameter enclosures in Lake 239 at the Experimental Lakes Area to increase inorganic Hg loading. Our main objectives were to (i) follow low-level additions (spikes) of isotope-enriched Hg

The mercury experiment to assess atmospheric loading in Canada and the United States (METAALICUS) aims at establishing the link between atmospheric deposition of mercury (Hg) and Hg concentrations in fish. As part of this initiative, we conducted an

[1] As part of the Mercury Experiment to Assess Atmospheric Loading in Canada and the U.S. (METAALICUS), different stable Hg(II) isotope spikes were applied to the upland and wetland areas of a boreal catchment between 2001 and 2006 to examine retent

Although a positive relationship between atmospheric loadings of inorganic mercury (Hg(II)) to watersheds and concentrations of methyl mercury (MeHg) in fish has now been established, net wet and dry deposition of Hg(II) and MeHg to watersheds remain
