The retention of metallic mercury vapor by soils

Effect of temperature and air movement on the flux of elemental mercury from substrate to the atmosphere

“…Heating of the core directly using a heating tape resulted in a positive temperature gradient with depth ( Figure 5 (Table 4). [Fang, 1978;Landa, 1978]. Flux of Hg ø from tailings (low in organic matter and predominantly silt-sized grains) used in this study would be greater than that expected from substrate of comparable concentrations but with higher amounts of both clay minerals and organic matter.…”

Distribution and sources of mercury in soils from former industrialized urban areas of Beijing, China

“…Due to the affinity of Hg for organic matter, soil Hg leaching rates should be small because the industrialized urban soils in Beijing have great concentrations of organic matter (2.02%; Table 1). Furthermore, the results of Landa (1978) sug- gested that in addition to quantity, the nature of a soils' organic matter also influences adsorption of Hg. It is important to pay close attention to DOC because of its large influence on sorption of Hg (Reddy and Aiken 2001).…”

Mobility of Mercury in the Volcanic/Geothermal Area of Nisyros (Greece)

“…Part of the released mercury is probably immediately retained within the soil, where it tends to form organo-metallic complexes (e.g. Landa, 1978). A good match between Hg 0 , H2S and CO2 concentration peaks was achieved, confirming the interdependence of these gaseous compounds and their common fumarolic origin.…”
