Non-Combustion Emissions of Hg in the Great Lakes Airshed

We propose to characterize the primary mercury emission pathways and   the speciation of the emitted mercury from the source or sources   selected for study. The measurements will be performed by the PI's   and their colleagues in a collaborative endeavor with the Minnesota   Pollution Control Agency (MPCA) during two separate field campaigns   in the Great Lakes Airshed. The measurements will be scheduled for   both warm and cool periods because of the strong influence of   temperature on fugitive mercury emissions. The data collected will   be subject to stringent quality assurance procedures such as those   we have developed for three previous EPA projects. The data will be  used with regional production and industrial land-use information to   estimate overall emissions from these source types. The speciation   measurements can be combined with a mercury deposition model to   estimate local dry deposition fluxes. These data will be compared to   regional emission inventories to assess the potential importance of  this source category.    (mercury); (Hg); (methylmercury); (chemicals of concern); (chemical   of concern); (air deposition);
