Cycling of Mercury in the Environment with Emphasis on the Importance of the Element in Acid Rain StudiesInformation on mercury and its environmentally significant chemical forms in the biogeochemical cycle is presented. Components of this cycle considered include the atmosphere, hydrometeors, surface ...
An improved understanding of the global mercury (Hg) cycle is important for our capacity to predict how regulatory efforts to reduce current emissions to air, water and land will affect Hg concentrations in environmental compartments, biota and humans. Hg is released into the environment through hum...
Mercury continues to circulate in the atmosphere, oceans, and terrestrial system for centuries to millennia before it returns to deep-ocean sediments. Areas of uncertainty in the global biogeochemical cycle of mercury include oxidation processes in the atmosphere, land-atmosphere and ocean-atmosphere ...
A short description of the main mechanisms controlling the mercury cycle in the European environment have been discussed giving special emphasis to the marine ecosystems and its effects on human health; meanwhile, existing gaps in our understanding of the quantitative and qualitative relationship between...
Modeling the Mercury Cycle in the Sea Ice Environment: A Buffer between the Polar Atmosphere and Ocean Sea ice (including overlying snow) is a dynamic interface between the atmosphere and the ocean, influencing the mercury (Hg) cycling in polar oceans. Howev... S Huang,F Wang,T Yuan - 《...
Chapter 1 addresses information gaps in the estimates of global emissions of mercury, calculating the possible contribution of crude oil processing to the global mercury cycle. The results of this study indicate that the potential emissions of mercury from petroleum refining are large, roughly ...
Although various mercury species in the environment and in the body may be metabolized and therefore represent a continuum of mercury species, exposures at work and from the diet differ in regard to the toxic effects and the applicable exposure biomarkers. Identification of the species is therefore...

Mercury is highly mobile in the environment. Anthropogenic sources contribute about one-third of mercury emissions to the atmosphere. Once in the atmosphere, long distance transport spreads mercury to distant areas of the globe. Both wet and dry precipitation processes remove mercury from the atmospher...
the environment. In particular, the global atmospheric distribution of Hg can result in the pollution of pristine areas with no known local point sources. The chemical speciation of Hg determines its mobility and toxicity and Hg methylation is a critical component of the mercury cycle. For example...
