Abstract:
The aim of present study was to assess the annual and seasonal variations of mass concentrations of gaseous species (NO, NO2, NOx, O3, SO2, CO, C6H6) and particulate matter PM10, PM2.5 (particulate matter less than 10 µm and less than 2.5 μm) in Bucharest area. The observational data set was extracted from the publicly available database of the Romanian National Air Quality for a period of five years: 2015–2019. Daily means of particulate matter and gaseous species mass concentrations at each site were statistically analyzed for the urban and suburban area. The hourly data were converted into daily means when it was necessary. The study assessed the annual urban impact over the surroundings of Bucharest and its evolution during the studied period. Results showed that urban impact is pollutant-specific and depends significantly on local pollution sources.
