Improvement in vehicle fleet composition has a positive effect on NO 2 and suspended particulate matter concentrations and also on benzene (but less). In the case
of ozone, the peak concentrations (which are limited in terms of health) decrease
and average annual concentrations increase (higher concentrations at night time).
The evaluation showed that secondary aerosols have a relatively high contribution to air pollution load by suspended particulate matter. This issue requires further
specification because higher concentrations of PM 10 are one of the major problems
of air quality protection in the capital city of Prague.
The influence of the green belt is rather small; it affects only few sites by small
decrease in temperature and consequent change in concentrations of pollutants
