Behavior of KCl sorbent traps and KCl trapping solutions used for atmospheric mercury speciation: stability and specificity [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
Atmospheric mercury speciation is of paramount importance for understanding the behavior of mercury once it is emitted into the atmosphere as gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate-bound mercury (PBM). GOM and PBM

Summertime elemental mercury exchange of temperate grasslands on an ecosystem-scale [PDF]

open access: yes, 2008
In order to estimate the air-surface mercury exchange of grasslands in temperate climate regions, fluxes of gaseous elemental mercury (GEM) were measured at two sites in Switzerland and one in Austria during summer 2006.

Air-Surface exchange of elemental mercury in uncontaminated grasslands : determination of fluxes and identification of forcing factors with micrometeorological methods and controlled laboratory studies [PDF]

open access: yes, 2008
The burning of fossil fuels, incineration of waste, smelting of metals and other industrial processes and applications have been adding considerable amounts of mercury to the atmosphere.

Observed in-plume gaseous elemental mercury depletion suggests significant mercury scavenging by volcanic aerosols [PDF]

open access: yes, 2023
Terrestrial volcanism is known to emit mercury (Hg) into the atmosphere. However, despite many years of investigation, its net impact on the atmospheric Hg budget remains insufficiently constrained, in part because the transformations of Hg in volcanic ...

Exchange Reactions Alter Molecular Speciation of Gaseous Oxidized Mercury

open access: yes, 2021
The knowledge of speciation of gaseous oxidized mercury (GOM) is crucial for understanding the atmospheric mercury chemistry and global cycle. Because of the low atmospheric abundance of GOM, its chemical analysis requires preconcentration and often ...

Long-Term Observations of Atmospheric Speciated Mercury at a Coastal Site in the Northern Gulf of Mexico during 2007–2018

open access: yesAtmosphere, 2020
Atmospheric mercury species (gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM), and particulate-bound mercury (PBM)), trace pollutants (O3, SO2, CO, NO, NOY, and black carbon), and meteorological parameters have been continuously measured ...

Atmospheric mercury chemistry: Detection, kinetics, and mechanism [PDF]

open access: yes, 2022
The presence of mercury in the environment is of global concern due to its toxicity. The atmosphere is an important transient reservoir for mercury released by human activities and natural sources.

Solar sail capture trajectories at Mercury [PDF]

open access: yes, 2002
Mercury is an ideal environment for future planetary exploration by solar sail since it has proved difficult to reach with conventional propulsion and hence remains largely unexplored.

Deciphering potential chemical compounds of gaseous oxidized mercury in Florida, USA [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
The highest mercury (Hg) wet deposition in the United States of America (USA) occurs along the Gulf of Mexico, and in the southern and central Mississippi River Valley.

An overview of atmospheric mercury monitoring at Auchencorth Moss, the UK EMEP Supersite in southern Scotland: trends, patterns and a source analysis

open access: yesE3S Web of Conferences, 2013
Speciated atmospheric mercury has been measures semi-continuously at the Auchencorth Moss field site in southern Scotland since 2004. Here we present an analysis of the data from 2009 to 2011 for the three species: elemental, gaseous oxidized (GOM) and ...
