Photoreduction of gaseous oxidized mercury changes global atmospheric mercury speciation, transport and deposition [PDF]

Nature Communications, 2018
Reduction of gaseous Hg(II) compounds drives atmospheric mercury wet and dry deposition to Earth surface ecosystems. Global Hg models assume this reduction takes place in clouds.

Long-Term Variation Characteristics and Health Risks of Atmospheric Hg in the Largest City in Northwestern China [PDF]

Toxics
In this study, gaseous element mercury (GEM) and gaseous oxidized mercury (GOM) in the atmosphere were continuously observed at a minute resolution from 1 April 2019 to 31 December 2020 in urban Xi’an, the largest central city in Northwestern China.

Near surface oxidation of elemental mercury leads to mercury exposure in the Arctic Ocean biota [PDF]

Nature Communications
Atmospheric mercury (Hg(0), Hg(II)) and riverine exported Hg (Hg(II)) are proposed as important Hg sources to the Arctic Ocean. As plankton cannot passively uptake Hg(0), gaseous Hg(0) has to be oxidized to be bioavailable.

Preparation of nano α-Fe2O3 and γ-Fe2O3 and used for elemental mercury removal [PDF]

MATEC Web of Conferences, 2022
The rod-shaped nano α-Fe2O3 and γ-Fe2O3 were prepared by a hydrothermal method. And the crystal phase structure, particle size, morphology and surface area of the synthesized nano α-Fe2O3 and γ-Fe2O3 were characterized by XRD and BET analysis.

Release of mercury halides from KCl denuders in the presence of ozone [PDF]

Atmospheric Chemistry and Physics, 2010
KCl-coated denuders have become a standard method for measurement of gaseous oxidized mercury, but their performance has not been exhaustively evaluated, especially in field conditions.
