Mercury in Wet Deposition

Measurements of trace metals in wet deposition are critical in order to examine the potential transport and input to aquatic and terrestrial ecosystems.

Natural and human emission sources can significantly increase trace metals concentrations in the atmosphere and in atmospheric deposition (Sweet et al., 2001). In addition,  acidic conditions present in precipitation are theorized to potentially make some toxic metals more bioavailable.

Frontier Geosciences has been working with the Mercury Deposistion Network (MDN) its parent program, the National Atmospheric Deposition Program (NADP) as the Hg Analytical Laboratory (HAL) since 1995.

With the original NAPD charge and increased sponsor interest, the MDN Hg Analytical Lab (HAL) and NADP, MDN Program Office began a new initiative in 1998 to develop a trace metals wet deposition capability. The focus of this initiative was to identify and develop the necessary tools needed to accurately measure a series of priority trace metals including but not limited to Ag, As, Be, Cd, Cr, Cu, Pb, Ni, Se, and Zn in addition to Hg.
