The objective of this study was to determine the natural concentrations of Hg and Se in 45
representative soil profiles from the Cerrado biome in central Brazil, and to correlate their …

Mercury (Hg) is one of the most toxic nonessential trace metals in the environment, with high
persistence and bioaccumulation potential, and hence of serious concern to environmental …

Mercury is a toxic element that becomes a problem when present at high concentrations in
soils. Mercury toxicity in soils varies depending on chemical species, concentration …

Mercury (Hg) toxicity in soils depends on Hg species and other physical and chemical
attributes, as selenium (Se) hotspots in soils, particularly relevant in Amazonian soils. The …

Sewage sludge usage as agricultural soil amendment is a well-known practice employed
worldwide. However, certain components may pose risks to the soil ecosystem. For a better …

Mercury (Hg) is a very well-recognized potential pollutant worldwide, and in the Amazon
biome illegal artisanal gold mining practices tend to maximize this environmental problem …

Artisanal and small-scale gold mining (ASGM) is the primary global source of anthropogenic
mercury (Hg) emissions. It has impacted the Amazon rainforest in the Peruvian region of …

Mercury is a metal which is potentially toxic for the environment. Many factors control its
retention in the soil, such as cation exchange capacity, pH, clay content, organic matter, and …

The heavy metal mercury (Hg) is one of the most complex and toxic pollutants. When
present in soils, it may impair plant growth, but the intensity of damage depends on the …

Mercury (Hg) is a widespread and toxic contaminant with potential for long-range
atmospheric transport. Previous work has shown that temperate and subtropical montane …
