%X Air quality was investigated in two regions, model for the Central-European beech sub-mountain forests: one situated near an aluminium plant in the  tiavnick¨¦ vrchy Mts, heavy polluted in the past, and the other situated in the relatively slightly polluted Kremnick¨¦ vrchy Mts, both in the West Carpathians Mts. In the years 1994--2006, we compared H+ concentrations between two beech stands at rotation maturity, a small-area clear cut and an open, non-forested plot. The highest proton load (H+) values (21.0mmol H+ day -1 m-2) were recorded on the small-area clear cut in the Kremnick¨¦ vrchy Mts, the highest in the mature forest stands: 7.9 mmol H+ day -1 m-2 in the  tiavnick¨¦ vrchy Mts, and 7.1mmol H+ day -1 m-2in the Kremnick¨¦ vrchy Mts. It follows that forest stands can act as filters capturing polluting substances. The results of the study show that the small-area forest regeneration at specific growth phase (small pole stage) starts to perform as a filter for gases and precipitation, that means, starts to perform the role of a forest stand. Apart from temporal and spatial trends, there was also evaluated the dynamics of proton load. The linear decreasing trend in the  tiavnick¨¦ vrchy Mts was affected by airborne pollutants, points out a reduction in polluting substances over the last two decades. On the other hand, the tendency in the Kremnick¨¦ vrchy Mts has been moderately increasing since the turn of the centuries.
