N2 - Negative effects of air pollution are except adverse effects on human health also associated with damages of material goods manifested in e.g. shorter service life of construction materials and faster material corrosion. Road tunnel environment is very specific since emissions of passing vehicles are not diffused to the surroundings and materials in the tunnel are thus immediately exposed to pollutants produced by traffic. Paper presents first results of measurements of specific air pollution in road tunnel of the project No TA01031043 “Quantification of specific pollution effect on materials and corrosion protection in tunnels”. Total concentration of nitrogen oxides was higher in the first sampling campaign. Nitrogen dioxide concentration was higher in the second sampling campaign that corresponds to higher traffic intensity. H2S and SO2 concentrations were almost similar in both campaigns. Higher PM2.5 concentrations were measured in the second sampling campaign that corresponds to higher traffic intensity associated with higher fine particle emissions from combustion processes. Lower PM10 concentrations in the second sampling campaign were measured probably due to conversion of some particles to the gaseous phase due to higher temperature and humidity. Progress of concentrations of all measured pollutants was typical by alternation of local minimal values and local maximum values in dependence on daytime resp. traffic intensity. Particle size distribution showed in both campaign dominant share of coarse PM fraction PM2.5-10 but also its very high fluctuation in time. The highest share of coarse fraction was determined in the time of rush hours in the morning, on the contrary the lowest share in night time.
