Mantle Hg isotopic heterogeneity and evidence of oceanic Hg recycling into the mantle
Nature Communications, 2022 This work demonstrates distinct mass-independent mercury isotope fractionation in global basalts, which suggests mantle Hg isotope heterogeneity and reveals large-scale translithospheric Hg recycling via plate tectonics.

Observations of atmospheric mercury in China: a critical review [PDF]
Atmospheric Chemistry and Physics, 2015 China presently contributes the largest amount of anthropogenic mercury (Hg) emission into the atmosphere in the world. Over the past decade, numerous studies have been conducted to characterize the concentration and forms of atmospheric Hg in China ...

Selenium Geochemistry and Health [PDF]
AMBIO: A Journal of the Human Environment, 2007 Selenium (Se) is a naturally occurring metalloid element, which is essential to human and other animal health in trace amounts but is harmful in excess. Of all the elements, Se has one of the narrowest ranges between dietary deficiency ( 400 µg day-1) (1) making it necessary to carefully control intakes by humans and other animals hence the importance

Spatial distribution of mercury deposition fluxes in Wanshan Hg mining area, Guizhou province, China [PDF]
Atmospheric Chemistry and Physics, 2012 The legacy of long-term mining activities in Wanshan mercury (Hg) mining area (WMMA), Guizhou, China including a series of environmental issues related to Hg pollution. The spatial distribution of gaseous elemental mercury (Hg0) concentrations in ambient

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C
