LYNAM, M. AND M. S. LANDIS. SIZE-SEGREGATED PARTICULATE MERCURY MEASUREMENTS IN STEUBENVILLE, OH AND DETROIT, MI, USA. Presented at 8th International Conference on Mercury, Madison, WI, August 06 - 11, 2006.
Impact/Purpose:
The objective of this research is to improve the understanding of gas phase mercury dry deposition phenomenon. Specifically the objectives will be to:
(1) Develop a scientifically sound first principal gas phase mercury dry deposition model
(2) Develop a direct measurement method(s) for gas phase mercury dry deposition
(3) Conduct gas phase mercury dry deposition model validation
Description:
This poster presents data on size-segregated particulate-phase mercury made during field intensive measurements in Steubenville, OH and Detroit, MI in 2004. The goal was to obtain information about size distribution of particle-associated mercury. A knowledge of size distribution gives rise to improved modeling of dry deposition fluxes of coarse and fine particle mercury and an assessment of the relative importance of each.
