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

, 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.

Characteristics and Risk Assessments of Mercury Pollution Levels at Domestic Garbage Collection Points Distributed within the Main Urban Areas of Changchun City

Toxics, 2021
The mercury that is released from the centralized treatment of municipal solid waste is an important source of atmospheric mercury. We chose the main urban area of Changchun as a representative area.

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

Atmospheric 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

Atmospheric mercury in the Southern Hemisphere tropics: seasonal and diurnal variations and influence of inter-hemispheric transport [PDF]

Atmospheric Chemistry and Physics, 2017
Mercury is a toxic element of serious concern for human and environmental health. Understanding its natural cycling in the environment is an important goal towards assessing its impacts and the effectiveness of mitigation strategies. Due to the unique

Detection and quantification of gas-phase oxidized mercury compounds by GC/MS [PDF]

Atmospheric Measurement Techniques, 2016
Most mercury pollution is emitted to the atmosphere, and the location and bioavailability of deposited mercury largely depends on poorly understood atmospheric chemical reactions that convert elemental mercury into oxidized mercury compounds.

Variation characteristics and influencing factors of mercury exchange flux on asphalt ground [PDF]

E3S Web of Conferences
Surface mercury release is an important source of atmospheric mercury, and asphalt pavement occupies a high proportion. However, the current characteristics of mercury exchange flux on asphalt ground are unclear, which is not conducive to assessing the ...

Regional Air Quality Model Application of the Aqueous-Phase Photo Reduction of Atmospheric Oxidized Mercury by Dicarboxylic Acids

Atmosphere, 2013
In most ecosystems, atmospheric deposition is the primary input of mercury. The total wet deposition of mercury in atmospheric chemistry models is sensitive to parameterization of the aqueous-phase reduction of divalent oxidized mercury (Hg2+).
