Abstract

    Year-round monitoring of atmospheric mercury deposition in wet deposition, aerosol (particulate-bound) and vapor (gaseous elemental) phases. The study is part of an integrated program of research and monitoring on atmospheric deposition in the Lake Champlain Basin coordinated over time with NOAA, University of Michigan Air Quality Lab, the Lake Champlain Research Consortium, the Mercury Deposition Network and the Atmospheric Mercury Network.
