Simultaneous measurements of bubble density in the sea subsurface and positive ions in the lower atmosphere were performed in the Baltic Sea in the summer of 1999. Bubbles in two size ranges, around 27 and 100 μm, were measured acoustically. Airborne positive charge was measured with a Gerdien instrument. Observed concentrations of air ions varied from 60 cm−3 up to 600 cm−3. The relative role of bubbles and wind speed on the positive air ion concentrations over the brackish water of the Baltic Sea is discussed. The parameters of a model of a log-log dependence between charge concentration and bubble density are calculated. The correlation functions between time series of concentrations of positive charges over the sea and gas bubbles averaged over a depth range from 0.4 to 4 m and wind speed are presented. There was zero lag between the cross-correlation maxima of charge and bubbles, but there was a phase lag of one and a half hours between charge and wind speed.

This work analyzes the influence of air-ions of different types and concentrations on people subjected to physical effort and at rest. The outcome of the conducted research indicates that air-ions at a concentration level of 7.5 million ions/cm³ decrease the consumption of O₂ by around 20%, and release CO₂. Furthermore, the positive air-ions shorten the period necessary to achieve the anaerobic change threshold by almost 70%, at a high significance ratio of 0.001. A secondary research outcome also shows that the change of these physiological indicators probably results from the permeation of ionized molecules to the lower parts of human lungs.
