Dry deposition fluxes and mass size distributions of Pb, Cu, and Zn measured in southern Lake Michigan during AEOLOS

The dry deposition fluxes and atmospheric size distributions of anthropogenic metals such as Pb, Cu and Zn were investigated in southern Lake Michigan. The investigation was part of the Atmospheric Exchange Over Lakes and Oceans Study, which sought to determine the effects of coastal urban atmosphere contaminated with hazardous air pollutants on atmospheric deposition to adjacent Great Lakes. Results revealed that the flux of Pb, Cu, and Zn were significantly higher in Chicago than both South Haven and Lake Michigan.
