Resumen

Аir quality control and management is one of the areas in which Europe has been the most active in recent years. Air quality assessment is the process of determining the nature of ambient air pollution using monitoring and supplementary techniques such as modelling. Aim of this study was to evaluate the air pollution as a result of the traffic in the transport tunnel of “Tsar Boris III Obedinitel” Boulevard, situated under the Architectural Reserve “Old Town” in the central part of Plovdiv. Analyses included two consequent steps: (i) calculating the emissions of exhaused gases from the motor vehicles in the tunnel using the dispersion modeling software; (ii) comparing the values obtained with data from the automatic measuring station of the air quality, located in proximity of the tunnel. Our study revealed that the main air pollutant in the tunnel is the nitrogen oxides whose concentrations were 4 to 6 times higher than TLV. Carbon oxide concentrations were 5 times lower than TLV and those of the soot – two times lower. Curves of the NO_x, CO and dust concentrations changes in both cases (modelled and measured, respectively) are parallel which confirms the validity of the model used.
