Gaseous Elemental Mercury Fluxes in New York City
Water, Air, and Soil Pollution, 2002As with many urban environments, a number of sources of airborne elemental mercury (Hg°) exist in New York City, yet little research has been conducted to examine the flux and sources of mercury in New York. In this study, we conducted ambient monitoring of Hg° at six locations in New York City. Airborne Hg° averaged 3.84±0.10 ng m-3 and 3.70±0.08 ng m-

Comprehensive mercury (Hg) budgets were constructed in two typical subtropical forests in southern China in 2014 to quantify Hg (gaseous elemental Hg, Hg0, and reactive Hg, HgII) input and output fluxes and Hg retention in forests, consequently exploring the roles of subtropical forests in the global Hg cycle.

Characteristics of Gaseous Elemental Mercury in a Suburban Area of Shanghai, China
Bulletin of Environmental Contamination and ToxicologyTo clarify gaseous elemental mercury (GEM) in suburban megacities in the Yangtze River Delta region, China, we observed GEM concentrations from December 2019 to November 2020 in Wujing town, a suburban area of Shanghai. The annual mean GEM concentration was 1.44 ± 0.88 ng m-3.

Homogeneous and heterogeneous oxidation of gaseous elemental mercury
2012Le mercure est un polluant atmosphérique globale avec le comportement les cyclismes complexes. Deux tiers du mercure présent dans notre atmosphère est d'origine anthropique. L'oxydation chimique de mercure élémentaire gazeux régit la vitesse des dépôts de mercure sur la plupart des lacs, des terres et des océans.

Polarity effect of pulsed corona discharge for the oxidation of gaseous elemental mercury
Chemosphere, 2011The effect of polarity on the oxidation of Hg(0) was examined in the presence of O(2) via a pulsed corona discharge (PCD). The experimental result showed no difference in the energy yield of Hg(0) oxidation at both positive and negative PCDs (∼8 μg Hg Wh(-1) at following conditions: total flow rate=2 L min(-1) (Hg(0)=50 μg Nm(-3), O(2)=10%, and N(2 ...

Exchange pattern of gaseous elemental mercury in an active urban landfill facility
Chemosphere, 2008The environmental behavior of gaseous elemental mercury (Hg) in the ambient air was investigated from the center of a municipal landfill site (area approximately 0.6km(2)) located in Dae Gu, Korea in the winter of 2004. In order to provide insight on the Hg exchange processes in strong source areas, we continuously analyzed Hg concentration gradients ...

Variability of the Gaseous Elemental Mercury Sea–Air Flux of the Baltic Sea
Environmental Science & Technology, 2007The importance of the sea as a sink for atmospheric mercury has been established quantitatively through models based on wet and dry deposition data, but little is known about the release of mercury from sea areas. The concentration of elemental mercury (Hg0) in sea surface water and in the marine atmosphere of the Baltic Sea was measured at high ...

Gaseous Elemental Mercury Oxidation by Non-thermal Plasma
2009The effects of the discharge tooth wheel number and the concentrations of CO2, NO and SO2 in the simulated flue gas on elemental mercury oxidation by non-thermal plasma were investigated by using a link tooth wheel-cylinder reactor energized by a negative high voltage DC power supply. The results indicated that a significant amount of elemental mercury

Abstract Deposition of atmospheric elemental Hg (Hg 0 ) to soils may be an important pathway for the transfer of Hg 0 to terrestrial ecosystems. In this study a laboratory method was applied to investigate the role of soils with natural background Hg concentrations ( 0 and to identify factors influencing Hg 0 exchange between these soils and air ...
