Land-Atmosphere Dynamics of Mercury and Ecological Implications for Adirondack Forest Ecosystems

In this study, researchers plan to continue ongoing measurements and   start new research which will be essential for New York in its   assessment of atmospheric mercury deposition and its effects, and in   the initiation of mercury monitoring activities. The investigators   will focus on one of the areas of New York most highly impacted by   air pollution: the Adirondacks.     This is a two phase study:  1) Continuing ongoing measurements of atmospheric mercury forms   through the U.S. EPA Mercury Monitoring Project and wet mercury   deposition through the Mercury Deposition Network at the Huntington   Forest in the central Adirondacks. Researchers will use measurements   of air mercury concentrations together with back-trajectory analysis   to evaluate source areas of mercury emissions to the Adirondacks. In   addition, they will conduct detailed studies of atmosphere-forest   exchange of mercury in hardwood and conifer forest plots at the   Huntington Forest, including measurements of throughfall, foliar   mercury uptake, litterfall, soil mercury evasion, soil drainage   losses and soil accumulation. Researchers will also compare and   contrast mercury deposition and cycling at hardwood and conifer   forests to gain insight on mercury dynamics in New York forest   ecosystems. They will also compare and evaluate three independent   approaches of quantifying dry mercury deposition: total ecosystem   deposition, deposition to surrogate surfaces and the inferential   approach.    2)Researchers will extrapolate what they have learned from detailed   process studies of mercury deposition at the Huntington Forest to   the entire Adirondack ecosystem through a survey of foliar and soil   mercury at 75 diverse forest plots located across the Adirondack   region.     (New York); (mercury); (toxic metal); (toxic metals); (Adirondack   Mountains); (chemicals of concern); (chemical of concern)
