Abstract:
This study aimed to characterize urban air pollution in 33 cities across Romania in 2019 and 2020. The atmospheric main pollutant mass concentrations, particulates PM10 and PM2.5 and gaseous species NO2, CO, SO2, O3, were extracted from the database of the National Air Quality Monitoring Network from 01.012019 to 31.12.2020. The time-series were statistically analyzed for each city for the representative month of each season and then used to estimate the pollutant impact on the surrounding regions. Results show significant decreases for most pollutants in most cities especially spring of 2020. Maps of interpolated mass concentrations reveal regional significant differences with pollutant-specific hot- and cold-spots in Romania. In addition to social and traffic restrictions, the decreases are higher or lower depending on other factors (topography, climatic factors, degree of industrialization of the area, etc.). This work constitutes a good database to characterize de urban air pollution in major cities and the spatial distribution of their impact around and could help the authorities in their measures to better control pollutant emissions or to investigate the impact on population health under various future economic development scenarios.
