The present and more recent observations suggest that the ozone is an indispensable, endogenous molecule form, and so it can be detected and measured practically in all biological systems. There are already different indirect and direct methods for the detection and measurement of this small molecule. The endogenous formation of ozone in the biological world may open a totally new horizon, e.g., in the topics of disease resistance and cell proliferation. Special efforts and more and more efficient methods are needed for observing the endogenous reactions and functions of this very reactive key molecule.

Abstract  

Downward flux of stratospheric ozone contributes to the near ground level ozone concentrations. The intensity, amount of vertical ozone flow can be evaluated by the ratio of two cosmogenic radionuclides (33P/32P, 7Be/32P). Some examples presented in this paper are demonstrating the possibilities of this method. The application of tracer method makes evident the seasonal variations (with maxima during the spring — summer months and minima during winter) of the amount of stratospheric ozone in the ground air. Average monthly contribution from stratospheric ozone in the lower level of the atmosphere ranged from 0 to 18% in 1998–99. During short term intervals (2–3 days) the amount of the stratospheric ozone can increase up to ∼90%.
