This study presents data on mercury (Hg) concentrations, stochiometric relations to carbon (C) and nitrogen (N), and Hg pool sizes in four Sierra Nevada forest sites of similar exposure and precipitation regimes, and hence similar atmospheric deposit

High-elevation red spruce [Picea rubens Sarg.]-Fraser fir [Abies fraseri (Pursh.) Poir] forests in the Southern Appalachians currently receive large nitrogen (N) inputs via atmospheric deposition (30 kg N ha�1 year�1) but have limited N retention

Concentrations of mercury (Hg) in live foliage increased ten-fold from spring bud break (mean ± std. dev. from bothsites: 3.5±1.3 ng g-1) to autumn litterfall(36±8 ng g-1). Mercury in foliage did not behavesimilarly to eight other elements with kn

Air/surface exchange of mercury was investigated over background soils at five sites in the Tahquamenon River watershed in the Michigan Upper Peninsula in the summer of 1998. Measurements of Hg fluxes were performed during middayperiods using the ORN

There are few reliable data on the speciation of Hg in ambient air, although this information is critical to understanding the fate of Hg once released from point sources. The water soluble species of Hg that are thought to exist in flue gases would

In contrast to recent rapid growth in the field data on mercury flux over soils, our knowledge and understanding of the emission processes and controlling mechanisms still remains limited. Many processes could control emission of mercury from soils.

The modified Bowen-ratio (MBR) technique is a micrometeorological method that can be used to estimate air-surface exchange rates, providing differences in concentrations between two heights can be resolved. Application of the MBR method requires that

A pilot network of three U.S. sites was initiated to test the feasibility of quantitating arsenic, cadmium, copper, manganese, lead, and zinc in wet deposition, and to make recommendations for a subnetwork at site and training levels compatible with
