This study presents the assessment of the PM10 emissions in areas from the south of
Bucharest and Ilfov county, for a period of 11 years, during 2008-2018, taking into
consideration the most important meteorological parameters with influence to air pollution,
such as relative humidity, temperature, wind direction, and wind speed. During the
study period, the mean annual concentrations of PM10 decreased from 43.92 mu g/m(3)
to 29.67 mu g/m(3), expressed as a percentage change the decrease was 35.45% and 29.03%
at the B-4 and B-7 stations, respectively. The Pearson correlation coefficient was
significantly higher in the cold season (November-April). In order to further investigate
the relations of air quality and wind direction pollution roses were calculated and
the results indicate that the highest concentrations of PM10 occur in B-4 and B-7
at the southwestern and west direction of wind.
