Wet deposition flux of trace elements to the Adirondack region

Wet deposition samples from two locations in the Adirondack region of New Y ork were analyzed for trace elemental composition by instrumental neutron a ctivation analysis. Annual fluxes of the measured species were determined b y precipitation-weighted and linear-regression methods. Despite several epi sodes of high deposition fluxes, the cumulative areal wet deposition of tra ce elements increased fairly linearly (r(2)>0.9) over the two year sampling period at both sites. This implies that short duration sampling programs m ay be used to estimate long-term fluxes and cumulative wet deposition impac ts. Based on the magnitude of their fluxes. the measured species have been divided into four groups: acidic onions, electroneutral balancing cations. and minor and trace elements anthropogenic origin.
