TLDR
Preliminary scaling of emissions from one of these areas and for western North America indicates that mercury enriched areas may be significant sources of mercury to the atmosphere, and that their contribution to regional and global atmospheric budgets needs to be reassessed.About:

TL;DR: In this paper, the authors provided an up-to-date assessment of global mercury emissions from anthropogenic and natural sources, including re-emission processes and primary emissions from natural reservoirs.

A review of global environmental mercury processes in response to human and natural perturbations: Changes of emissions, climate, and land use
TL;DR: Estimates of gaseous Hg0 emissions to the atmosphere over land, long considered a critical Hg source, have been revised downward, and most terrestrial environments now are considered net sinks of atmospheric Hg due to substantial Hg uptake by plants.

Accumulation of atmospheric mercury in forest foliage

TL;DR: This article used unique mesocosms to examine the role that plants play in accumulating and transforming atmospheric Hg and found that approximately 80% of the total Hg accumulated in the aboveground biomass was found in the leaves, and roughly 1% of that Hg was methylated.

Geochemistry of Mercury in the Environment
TL;DR: The current understanding of the biogeochemistry of mercury cycling at Earth's surface (soils, sediments, natural waters, and the atmosphere) is presented in this article, which includes anthropogenic interferences (i.e., mercury pollution) and biological mediation, which affect significantly the speciation, behavior and fate of mercury in the environment.
Journal ArticleDOI
An update on the natural sources and sinks of atmospheric mercury
TL;DR: The role of terrestrial surfaces as sources and sinks of atmospheric Hg must be quantified in order to develop regional and global Hg mass balances, and to assess the efficacy of regulatory controls on anthropogenic point sources in reducing human Hg exposure as mentioned in this paper.

The composition of the continental crust
TL;DR: In this paper, a new calculation of the crustal composition is based on the proportions of upper crust (UC) to felsic lower crust (FLC) to mafic lower-crust (MLC) of about 1.6:0.4.

Distribution of the Elements in Some Major Units of the Earth's Crust
Karl K. Turekian,K. H. Wedepohl +1 more
TL;DR: A table of abundances of the elements in the various major units of the Earth's lithic crust with a documentation of the sources and a discussion of the choice of units and data is presented in this article.

Quantitative assessment of worldwide contamination of air, water and soils by trace metals
Jerome O. Nriagu,Jozef M. Pacyna +1 more
TL;DR: Calculated loading rates of trace metals into the three environmental compartments demonstrate that human activities now have major impacts on the global and regional cycles of most of the trace elements.
Journal ArticleDOI
A global assessment of natural sources of atmospheric trace metals
TL;DR: For most of the toxic metals, the natural fluxes are small compared with emissions from industrial activities, implying that mankind has become the key agent in the global atmospheric cycle of trace metals and metalloids as mentioned in this paper.
