Natural and anthropogenetic pollution limits of the stratospheric ozone

Abstract

Starting from the irreversible thermodynamics stability analysis of the ozone layer in the far equilibrium conditions, an analytical procedure for separating the natural and anthropogenetic ozone pollution channels was developed. In this way the upper and the lower limits of the ozone layer concentrations were calculated, as well as, the lower (natural) limits and the upper limits (permitted pollution) of the pollutants that destroy ozone. The results are important in practical applications allowing one to include the ozone layer depletion as statements on the NO/sub 2/ and freons F11 and F12 in the air quality standards.
