The purpose of the paper has been presenting the evolution of concentrations for four main air pollutants in Craiova, so as to show the situation of air quality in this major city in Southern Romania, also finding the best statistical model to fit the recorded data for particulate matter with diameter of less than 10 microns transported by the wind within the urban area.
In order to accomplish this purpose, experimental data have been gathered during the entire year 2018 in the above-mentioned town, by two air quality monitoring stations for: nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO) and suspended particulate matter (PM10). It was shown that none of the monitored gaseous air pollutants exhibited an alarming temporal variability, although some values close to the allowed limit or even beyond it were recorded during the monitoring period; however, PM10 daily average in the ambient air has been often higher than the European Union threshold, so that urgent measures for reducing air pollution have to be taken in Craiova, as well as in other developed cities in Romania, for this country to get the exoneration regarding air pollution from the European Union and for the people living here to improve their life quality. The best statistical model to fit the recorded data for PM10 seemed to be the log-normal distribution, which was found appropriate for describing the percentage of appearance for each range of concentration, this three-dimensional diffusion model being shown to be consistent with the experimental data, providing an important and useful tool in describing an important aspect of air quality monitoring. |
