Observation and analysis of speciated atmospheric mercury in Shangri-La, Tibetan Plateau, China [PDF]

Atmospheric Chemistry and Physics, 2015
This study reports the concentrations and potential sources of speciated atmospheric mercury at the Shangri-La Atmosphere Watch Regional Station (SAWRS), a pristine high-altitude site (3580 m a.s.l.) in Tibetan Plateau, China. Total gaseous mercury (TGM,

The monitoring of atmospheric mercury species in the Southern Indian Ocean at Amsterdam Island (38°S)

E3S Web of Conferences, 2013
The role of oceans in the global cycle of mercury is still poorly characterized, mainly because of a lack a long-term data on atmospheric mercury concentrations in the remote Southern Ocean.

Speciated mercury measurements in ambient air from 2009 to 2011 at a Central European rural background monitoring site

E3S Web of Conferences, 2013
Since January 2009 highly time-resolved mercury speciation measurements in ambient air are carried out at the Central European German EMEP monitoring station and measurement site of the German Federal Environment Agency “Waldhof“, providing the longest ...

Mercury in the snow and firn at Summit Station, Central Greenland, and implications for the study of past atmospheric mercury levels [PDF]

Atmospheric Chemistry and Physics, 2008
Gaseous Elemental Mercury (Hg° or GEM) was investigated at Summit Station, Greenland, in the interstitial air extracted from the perennial snowpack (firn) at depths ranging from the surface to 30 m, during summer 2005 and spring 2006.

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

E3S 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 ...

Method development estimating ambient oxidized mercury concentration from monitored mercury wet deposition [PDF]

Atmospheric Chemistry and Physics, 2013
To quantify mercury dry deposition, the Atmospheric Mercury Network (AMNet) of the National Atmospheric Deposition Program (NADP) was established recently to monitor the speciated atmospheric mercury (i.e.

Passive air sampling of gaseous elemental mercury: a critical review [PDF]

Atmospheric Chemistry and Physics, 2016
Because gaseous elemental mercury (GEM) is distributed globally through the atmosphere, reliable means of measuring its concentrations in air are important.

Enhanced production of oxidised mercury over the tropical Pacific Ocean: a key missing oxidation pathway [PDF]

Atmospheric Chemistry and Physics, 2014
Mercury is a contaminant of global concern. It is transported in the atmosphere primarily as gaseous elemental mercury, but its reactivity and deposition to the surface environment, through which it enters the aquatic food chain, is greatly enhanced ...

Development, characterization, and testing of a personal passive sampler for measuring inhalation exposure to gaseous elemental mercury

Environment International, 2021
Inhalation of gaseous elemental mercury (GEM) is an occupational exposure concern for workers handling elemental mercury or mercury-containing waste. GEM is also often present near historically mercury-contaminated sites, potentially resulting in low ...

Transformations of mercury in processes of solid fuel combustion – review

Archives of Environmental Protection, 2017
The paper presents current reports on kinetics and mechanisms of reactions with mercury which take place in the exhaust gases, discharged from the processes of combustion of solid fuels (coals). The three main stages were considered.
