Mercury in the terrestrial environment: a review

Abstract: Environmental contamination by mercury is and will continue to be a serious risk for human health. Pollution of the terrestrial environment is particularly important as it is a place of human life and food production. Publication presents a review of the literature on issues related to Hg pollution of the terrestrial environment: soil and plants and their transformations. Different forms of atmospheric Hg may be deposited on surfaces by way of wet and dry processes. These forms may be sequestered within terres… Show more

“…Of course, it has to be said that this statement is based on only one sample from one location, and w (Hg) total and w (Hg) MMHg may vary considerably in the whole washing bed due to variations in the soil conditions. Because this is not the only washing bed where sediment from Finow Canal has been deposited in the past, it is to be expected that these washing beds contaminated with legacy Hg have been and will be contributing largely to atmospheric Hg 0 emissions, as soils have been described as a source for Hg 0 [ 22 ].…”

“…An area of broad interest is Hg speciation because of its complex biogeochemical cycle [ 20 ], including natural methylation processes producing extremely toxic monomethylmercury (MMHg), especially in the aquatic environment. Sediments and soils can act as sinks for inorganic Hg species, while they are simultaneously sources of volatile (Hg 0 ) and organic species, such as MMHg [ 20 22 ], although the amount of substance fraction of MMHg in total Hg is suggested to be as low as 0.1–1% [ 20 , 23 ]. Natural background levels of Hg in soils and sediments are thought to be in the order of 0.1 mg/kg [ 20 , 22 ], corresponding to natural MMHg mass fractions between 0.1 and 1 μg/kg.…”

“…Other forms of atmospheric Hg are reactive gas phase Hg (RGM) and particulate phase Hg (TPM). RGM and TPM have a shorter atmospheric residence time than GEM (hours to days), and due to high water solubility and adsorption on particles, they tend to affect the terrestrial ecosystem locally or regionally by wet and dry deposition [ 6 ].…”
