Summary: Analysis of the diversity of conditions of the aeolian circulation of pollutants transported by mineral and organic particles and snow was carried out over the Carpathian Foothills marginal zone between the Raba and Uszwica Rivers. It was based on the results of studies applying to the conditions, effects and course of airborne deflation, transport and deposition of the above mentioned types of material and on the characteristics of selected elements of the local environment. Displacement of mineral and organic material and snow by wind may occur in various parts of the area and at different seasons of the year, depending on land use, inclination and exposure, changes of wind directions and velocities, and the condition of the soil. Only the transport of suspended mineral dust and organic matter from forests occurs all year long and at all wind velocities. Organic matter from meadows is involved in the airborne transport only during the snowless season and from fields only during the vegetation season. Displacement of mineral particles and snow in the near-ground layers of the air requires the wind velocity to reach ł5 m s-1. Mineral material from the fields is supplied from ploughed land only during the postvegetation period . To classify the periods of potential occurrence of aeolian processes, the number of occurrences of windward and leeward orientation of areas with different use and exposure was analyzed. Comparison of their durations led to the designation of areas with conditions particularly favourable to deflation, deposition or equally-favourable to both processes. Areas with conditions favourable to the removal or accumulation of material occupy a similar surface but they seldom form concentrated clusters. This is a result of the limited range of matter circulation, which mainly takes place within areas located between the valleys. For this reason also, matter exchange between the marginal zone of the Foothills and the adjacent territories is limited.
