In this paper, the modeling results are presented of point emitter geometric parameters determining the dispersion of dust pollution in the atmospheric air and finally also dustfall. The parameters include: the height and diameter of the emitter. Using the maps generated by “Ek100w” programme of Atmoterm company from Opole, Poland, an analysis of the PM10 dustfall value distribution on the analyzed area has been made. Fraction of dust - PM10 - was emitted from emitters of various working parameters. Three situations were analyzed: emission from a one-family (detached) building, from and industrial plant and from a power plant. Different heights and diameters for the above cases were analyzed. What results from the work, is that the mentioned parameters have a significant influence on the value of dustfall on the area surface at different distances from the emitter. With the increase of the height and diameter of the emitter, the values of dustfall decrease. The distance of the maximal values occurrence also increases. Results of similar analysis and available tools allow to design emission in practice, and thus allow a maximal limitation of ambient concentration of pollution and dustfall in areas especially exposed to industrial and superficial emission.
