TL;DR: It is approximate that about 550 M mol of Hg has been mobilized globally from soil as a result of deforestation during the past two centuries, comparable to, if not greater than, the amount of anthropogenic Hg hypothesized by others to have been sequestered by the soil reservoir since Industrialization.

Challenges and opportunities for managing aquatic mercury pollution in altered landscapes.
Heileen Hsu-Kim,Chris S. Eckley,Darío Achá,Xinbin Feng,Cynthia C. Gilmour,Sofi Jonsson,Carl P. J. Mitchell +6 more
TL;DR: The objective of this paper is to synthesize the scientific understanding of how Hg cycling in the aquatic environment is influenced by landscape perturbations at the local scale, perturbation that include watershed loadings, deforestation, reservoir and wetland creation, rice production, urbanization, mining and industrial point source pollution, and remediation.
Recent advances in understanding and measurement of mercury in the environment: Terrestrial Hg cycling.

TL;DR: This review documents recent advances in terrestrial mercury cycling in the framework of three Hg "gateways" to the terrestrial environment: inputs from the atmosphere, uptake in food, and runoff with surface water.

Mercury Pollution in Amapá, Brazil: Mercury Amalgamation in Artisanal and Small-Scale Gold Mining or Land-Cover and Land-Use Changes?
Rebecca Adler Miserendino,Rebecca Adler Miserendino,Jean Remy Davée Guimarães,Gary Schudel,S. Ghosh,José Marcus Godoy,Ellen K. Silbergeld,Peter S.J. Lees,Bridget A. Bergquist +8 more
TL;DR: In this article, stable Hg isotope analyses were applied to sediment cores, surface sediments, and soils from two aquatic ecosystems in Amapa, Brazil, one downstream of ASGM activities and one isolated from ASGM.

An investigation of mercury sources in the Puyango-Tumbes River: Using stable Hg isotopes to characterize transboundary Hg pollution.
Gary Schudel,Rebecca Adler Miserendino,Marcello M. Veiga,P. Colon Velasquez-López,Peter S.J. Lees,Sean Winland-Gaetz,Jean Remy Davée Guimarães,Bridget A. Bergquist +7 more
TL;DR: The magnitude and extent of downstream Hg, lead, copper and zinc contamination coupled with the Hg isotopes suggest that it is unlikely that the smaller artisanal-scale activities, which do not use cyanidation, are responsible for the pollution.

Mobility of mercury in soil and its transport into the sea
TL;DR: The analysis showed that due to changes of meteorological and hydrological conditions Hg can enter rivers and then be introduced into the marine environment in various forms and affects increasing of availability of the most dangerous Hg form in the water systems.

Loss on ignition as a method for estimating organic and carbonate content in sediments: reproducibility and comparability of results.
TL;DR: In this paper, five test runs were performed to assess possible bias when performing the loss on ignition (LOI) method to estimate organic matter and carbonate content of lake sediments.
Mercury as a Global Pollutant: Sources, Pathways, and Effects
TL;DR: Understanding of sources, atmosphere-land-ocean Hg dynamics and health effects are synthesized, and integration of Hg science with national and international policy efforts is needed to target efforts and evaluate efficacy.

Mercury biogeochemical cycling in the ocean and policy implications.

TL;DR: This analysis suggests that while atmospheric deposition is the main source of inorganic Hg to open ocean systems, most of the CH₃Hg accumulating in ocean fish is derived from in situ production within the upper waters (<1000 m), and that the deeper waters of the oceans are responding slowly to changes in atmospheric Hg inputs.

Effects of Forest Management on Soil Carbon Storage
Dale W. Johnson,Dale W. Johnson +1 more
TL;DR: The literature on soil C change with forest harvesting, cultivation, site preparation, burning, fertilization, N fixation, and species change is reviewed in this paper, showing no significant change (± 10%) with harvesting only, a few studies showed large net losses, and a few cases showed a net gain following harvesting.
