Air Pollution - The Old Problem of Bacau Municipality

Abstract

Following the evaluation of air quality at national level, the municipality of Bacau falls under the management regime I. The evaluation of air quality was carried out both by measurements at fixed points, with the help of measuring stations that are part of the National Air Quality Monitoring Network, central public authorities for environmental protection, as well as based on the results obtained from the mathematical modeling of the dispersion of pollutants emitted into the air. The main sources of air pollution in Bacau are represented by combustion in the energy sector, production processes, road traffic and individual heating systems. These sources require continuous monitoring to find the best possible techniques for minimizing and reducing the amount of pollutants released into the atmosphere. Emissions of nitrogen oxides (NOx) on the territory of Bacau municipality are released into the atmosphere especially in urban areas (inhabited areas) and on industrial platforms. Once released into the air, pollutants, due to the dispersion phenomenon, can be transported to different areas depending on the weather conditions present. The unfavorable combination of dispersal, weather conditions, topography of the region and pollutant concentrations can lead to exceeding limit values, with negative effects on human health.
