Content of dissolved oxygen and carbon dioxide in rainwaters and groundwaters within the forest reserve of the Kampinos National Park and the urban area of Warsaw, Poland

Abstract

Research were conducted within two experimental fields differing from each other in land use. The source of percolating water and shallow groundwater within both fields is primarily the rainwater which controls their ionic and gaseous content. Considerable air pollution affects the rainwater falling on Warsaw. The chemical composition of the rainwaters should be considered as the first factor responsible for the observed differences in ionic and gaseous composition of percolating water within the two experimental fields. Subsequent chemical changes of these waters during infiltration depend on the character of the geologic profile and the rate of infiltration.
