Reactive mercury
Did you know?
WebDissolved gaseous mercury (DGM) and reactive mercury (RHg) are important mercury (Hg) forms in natural water bodies. Knowledge of the concentration levels and isotope compositions of DGM and RHg in aquatic ecosystems is of crucial importance for understanding the fate of Hg and Hg cycle. WebJun 21, 2006 · Reactive mercury is produced primarily by gas-phase reactions. Aqueous reactions tend to convert reactive mercury back to its elemental form, but the most important aqueous reactions (with HO2 and O2-) are problematic (Gartfeld and Jonnson, 2003). Model results suggest that gas-phase conversion from elemental to reactive …

WebJan 28, 2013 · The standard detection method uses a potassium chloride-coated quartz surface to trap reactive mercury compounds. The new technique measures total and elemental airborne mercury levels via atomic fluorescence spectroscopy and determines the amount of reactive species from the difference. WebHowever, reactive mercury was a narrowly constrained fraction of the total mercury, making up only 4-16% of the total, showing evidence of the importance of dissolved organic matter on mercury transport. In sediments, higher concentrations of mercury were also determined near industrial discharges.
