Airborne Vertical Profiling of Mercury Speciation near Tullahoma, TN, USA

open access: yesAtmosphere, 2014
Atmospheric transport and in situ oxidation are important factors influencing mercury concentrations at the surface and wet and dry deposition rates. Contributions of both natural and anthropogenic processes can significantly impact burdens of mercury on

Measuring and modeling mercury in the atmosphere: a critical review [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Mercury (Hg) is a global health concern due to its toxicity and ubiquitous presence in the environment. Here we review current methods for measuring the forms of Hg in the atmosphere and models used to interpret these data.

Characteristics and Health Risk Assessment of Mercury Exposure via Indoor and Outdoor Household Dust in Three Iranian Cities

open access: yesAtmosphere, 2022
This study aims to increase our current knowledge on the concentration of particulate-bound mercury (PBM) in urban environments of three Iranian cities, where high concentrations of dust particles can act as carriers for mercury transport and deposition.

Estimation of speciated and total mercury dry deposition at monitoring locations in eastern and central North America [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Dry deposition of speciated mercury, i.e., gaseous oxidized mercury (GOM), particulate-bound mercury (PBM), and gaseous elemental mercury (GEM), was estimated for the year 2008–2009 at 19 monitoring locations in eastern and central North America.

Mineral Stabilization of Soil Organic Sulfur at the Continental Scale. [PDF]

open access: yesGlob Chang Biol
The conventional whole‐soil view treats soil organic sulfur (S) as a single bulk pool, obscuring the mechanisms governing its transformation, stabilization, and availability. Separating organic S into particulate organic sulfur (POS) and mineral‐associated organic sulfur (MAOS) distinguishes their contrasting sources, microbial transformations, and ...

Total mercury concentrations in an industrialized catchment, the Thur River basin (north-eastern France): geochemical background level and contamination factors [PDF]

open access: yes, 2003
River bottom sediments and soils were collected from the industrialized Thur River basin (north-eastern France) to assess mercury contamination. The regional geochemical background level of total mercury was evaluated to calculate mercury contamination ...

Impact of mercury atmospheric deposition on soils and streams in a mountainous catchment (Vosges, France) polluted by chlor-alkali industrial activity: The important trapping role of the organic matter [PDF]

open access: yes, 2006
Total atmospheric Hg contamination in a French mountainous catchment upstream from a chlor-alkali industrial site was assessed using Hg concentrations in the deepest soil horizon, in the stream bottom sediments, in river waters and in bryophytes.
