متن کاملThe rapid estimation of mercury in the atmosphere of workrooms.
To measure the hazard to the worker it is often necessary to determine the atmosphere concentration of mercury in a workroom. It should be borne in mind that inhalation of mercury, though probably the most dangerous, is not the only way by which mercury enters the body. It follows that a measurement of the mercury content of the atmosphere does not give a full indication of the hazard. Air anal...
متن کاملExchange of Mercury between the Atmosphere and Terrestrial Ecosystems
Once elemental mercury (Hg) enters the atmosphere, it may be globally distributed because of the fact that this form is relatively inert and recycled between terrestrial and aquatic surfaces. Terrestrial ecosystems may be sources, as well as shortand long-term sinks, for atmospheric Hg. Understanding whether an ecosystem is a source or sink and the magnitude of associated flux is critical for d...
متن کاملExchange of mercury between atmosphere and vegetation under contaminated conditions.
Adsorption and desorption of mercury was studied under laboratory conditions using moss (Sphagnum girgensohnii) and Rye grass (Lolium perenne) at different temperatures. Desorption was also studied in a transplantation experiment. The adsorption was rapid and strong for both plant species at different temperatures (+10 to +60 degrees C) and exposure times (1 h, 1 month) while the evaporation wa...
متن کاملAn examination of methods for the measurements of reactive gaseous mercury in the atmosphere.
Reactive gaseous Hg (RGHg), usually assumed to be HgCl2, may dominate the total Hg depositional flux due to its higher surface reactivity and water solubility. Three methods are currently used for RGHg sampling: multistage filter packs, refluxing mist chambers, and KCI-coated denuders, but none of these methods are considered standard. Field comparisons were performed at Chesapeake Biological L...
