Opis:: The article studies the data from a weekly campaign devoted to the study of the elemental composition of PM10 in a selected receptor, in a suburban area (Mazowieckie Voivodeship). The sampling point was located at the intersection of main roads and in the vicinity of a typical single-family housing, not far from the electrified Warsaw-Białystok railway line and a small heating plant. The research was carried out in the summer season, in order to minimize the impact of municipal emissions on the concentrations and elemental composition of PM10. A Horiba PX-375 X-ray fluorescence spectrometer was used to measure the one-hour concentrations of elements related to PM10. On the basis of the obtained results, the enrichment factors for PM10 in the analyzed elements (EF) were calculated and the principal components analysis (PCA) was performed. It was found that although the elemental composition of PM10 in all tested time intervals was noticeably influenced by the emissions from transport, the municipal emissions had a significant impact on the elemental composition, especially those related to coal combustion, and thus the concentration of PM10 during the study period. It seems that the possibility of observing the influence of all relevant sources on the composition and concentration of PM10 was possible owing to the use of hourly-averaged measurements of the elemental composition of PM10. In the case of daily averaged measurements, in a receptor with such PM10 elemental profile, it would be impossible to determine the periods, in which specific – qualitatively completely different – emission sources dominate.

Opis:: This work presents the first results of the metal in particulate matter PM10 analysis and source apportionment in one of the fire station garages in Poland. The study’s novelty includes the high temporal resolution of the elemental composition of PM-bound metals since the gamma-ray fluorescence spectrometer with the high temporal resolution was used in the study. The concentrations of PM10 were measured at the same time using the method of beta-ray attenuation. The concertations of PM10 and PM-bound metals were analyzed with a temporal resolution of 4 h. To identify the source apportionment of metals, three commonly used models were applied: principal component analysis (PCA), EPA UNMIX, and EPA PMF (positive matrix factorization). The concentrations of the investigated metals have high temporal variations while the concentrations of PM10 were low in the garage. The enrichment of PM10 was very high or high, especially in sulfur, zinc, arsenic, nickel, cadmium, and lead. PCA analysis, as well as UNMIX and PMF, showed a high impact of factors related to sulfur on the variability. It showed the impact of combustion, including combustion of liquid fuels, in fire engines may have a crucial impact on air pollution in the fire station. The PMF analysis allowed us also to identify factors responsible for external anthropogenic emissions on concentrations inside the garage. Other identified sources of PM10 and PM10-bound elements are mineral dust, and road dust related to non-exhaust emission, originating inside the firehouse (resuspension and abrasion) as well as from outside.

Opis:: The ambient concentrations and elemental composition of particles with aerodynamic diameters between 30 and 108 nm (quasi-ultrafine particles, q-UFP) were studied. The data came from 6 sites in Katowice and Zabrze, big cities in Upper Silesia, where particulate matter was sampled at urban background site and crossroads in Katowice and Zabrze, at highway in Katowice, and at urban road in Zabrze. The ambient concentrations of q-UFP and of 24 q-UFP-bound elements at these six sampling sites have been discussed in the paper. The q-UFP mass concentrations in Upper Silesia did not appear high, they were not higher than in other areas. The percentages of the total mass of the examined elements in the q-UFP mass suggest that in Upper Silesia, within a typical residential area, q-UFP consist mainly of primary matter. At the sites under strong influence of road traffic emissions, where the contributions of the examined elements to the q-UFP mass were small, most probably, carbonaceous matter and elemental carbon build the core q-UFP mass. The majority of the elements in q-UFP are anthropogenic. Clear effects of local PM sources can be seen on the ambient concentrations of q-UFP-bound Al, Si, S, Cl, K, Sc, Ti, V, Cd, Cr, Mn, Co, and Sb.
