Atmospheric deposition of pollutants and nutrients can have a range of effects on aquatic and terrestrial ecosystems. Despite its ecological importance, it remains a challenge to model patterns of deposition across complex terrain and also to assess how forest ecosystems are reacting to chronic inputs of atmospheric deposition. I measured the lead (Pb) content of forest soils adjacent to atmospheric deposition monitoring stations throughout the central Appalachian Mountains to examine how well patterns of soil Pb relate to regional patterns of inorganic nitrogen (N) deposition. While I found no significant relationship between organic soil Pb content and N deposition, I …
