Seasonal ambient air particulates and metallic elements (Cr, Cu, Zn, Cd, Pb) pollutants dry depositions fluxes predictions and distributions with appropriate models at a farmland site

The Baklanov and Sorensen, Zhang, Wood and vegetation collection models all predict the least dry deposition of ambient air particles of size at 2.5 μm and all metallic elements. Moreover, this study further revealed that the particle size is the key parameter that influence the modelled dry depositions fluxes and resulted in the calculated/measured fluxes variations ratios for ambient air particles and metallic elements. Another influence parameter is the pollutants (particles, metallic elements) concentrations. When the particle size is fixed, the higher of the pollutants concentrations, the higher the calculated/measured fluxes ratios can be obtained at this farmland sampling site.
