The Evaluation of the Concentration of Benzo[a]Pyrene in the Air of Moravian-Silesian Region (Czech Republic) during Winter and Summer Seasons

Abstract:

The concentration of benzo [a] pyrene (BaP) was monitored at 40 selected sites of the Moravian-Silesian Region (Czech Republic) during winter and summer seasons. The concentrations of BaP were higher at all locations during winter than in the summer with a difference in values in the range of 0.66 to 47.08. The average concentration of BaP in the winter season was 14.67 ng/m³, whereas during the summer season this value reached 0.55 ng/m³. The highest average concentrations of BaP during winter and summer seasons in the values of 21.88 ng/m³ and 1.12 ng/m³, respectively were observed in the areas with predominant industrial activity. Conversely, the lowest concentration for both monitored periods were measured at the mountain and background sites and their values were 4.43 ng/m³ in winter and 0.07 ng/m³ in the summer. The value of the geochemical background was fixed at 1.79 ± 0.54 ng/m³. Finally, the value of diagnostic ratio of BaP and benzo [e] pyrene (BaP/BeP) greater than 1 indicated that the sources of BaP in the summer season were the local sources.
