Sažetak
Ozone (O3) and hydrogen peroxide (H2O2) volume fractions were calculated using the Master Mechanism (MM) model, author S. Madronich (NCAR, Boulder, CO, USA). MM is an atmospheric box model program for calculating the time evolution of atmospheric composition from initial amounts of atmospheric gases under chosen or varying conditions using reaction rate data and other physical parameters. The photolysis coefficients were calculated using the Tropospheric Ultraviolet Visible (TUV) program of the same author. The present study analyzes the relationships between different initial conditions (air temperature, relative humidity, levels of some atmospheric pollutants) and ozone and hydrogen peroxide levels in the air. The influence of the following compounds was tested: nitrogen dioxide (NO2), carbon monoxide (CO), volatile organic compounds (VOC), benzene, toluene and xylene (BTX). According to the model, H2O2 volume fractions in air increase with higher relative humidity and higher initial values of CO, VOC, BTX, H2O2 and O3. Higher initial NO2 values cause a decrease in H2O2 volume fractions. Ozone volume fractions in air rise with the increase of initial volume fractions of NO2, CO, VOC, BTX, H2O2 and O3. Temperature does not have any significant influence on the formation of H2O2 and O3.
