The purpose of the article was to analyse the reliability, maintainability, and availability estimates of firefighting and rescue engines. Analysing the reliability parameters of heavy firefighting and rescue vehicles over time requires knowledge of their failures. In this article, failure data from the six years of maintenance of ten heavy firefighting and rescue vehicles from ten were analysed in relation to two main subsystems. Reliability analysis was performed and the best-fit distribution was found, with the parameters calculated. For both subsystems, the chassis combined with the cabin and the superstructure, the 2P-Weibull distributionwas identified as the most suitable fit. The availability and maintenance indicators for each vehicle and the individual subsystems were calculated. It was clearly defined that there exists a significant difference between the two subsystems analysed in terms of failure characteristics, as well as maintainability and availability parameters.

Air pollution in the vicinity of roads is a complex and growing problem. In urbanised areas, there are many sources of dust emissions, but one of the main ones is road traffic. Investigating and assessing the physical and chemical properties of road dust and, more specifically, dust collected from surface courses is one way of providing an opportunity not only to identify the contribution of the emitters concerned to the formation of dust air pollution in the vicinity of roads but above all the environmental risks associated with traffic emissions. The study aimed to analyse the elemental composition of dust with a fraction <0.1 mm, collected from asphalt and concrete roads characterised by the highest technical and service parameters in Poland. The samples were analysed using a Shimadzu EDX 7000 energy-dispersive X-ray fluorescence spectrometer, then the results were statistically analysed using the t-Welch test, and the enrichment factors EF were determined. It was shown that road dust with a grain size of less than 0.1 mm collected from asphalt surface course was extremely highly enriched in Cu, Cr, Pb and S, while that from the concrete surface course was enriched in Zn and Zr, indicating a strong anthropogenic origin of these elements; exhaust gases were identified as their source. Irrespective of the type of surface course, very high dust enrichment occurs for Ca, Mn, Ni, S, Ti and Y. These elements may originate from the abrasion process of vehicle tyres. For road dust collected from both road types, the most similar EF values were found for Fe, K, Mn, Si, Sr and Ti. The source of these elements is most likely the roadside soil. It follows that the type of road surface is not the main determinant of the composition of road dust with a fraction <0.1 mm.

In recent years, heightened air pollution characterized by elevated levels of particulate matter and potentially toxic metals has become a prominent concern, particularly in densely populated urban areas, which may pose a threat to the health of the population. The present study aims to conduct a comprehensive health risk assessment of heavy metals exposure via inhalation, with a focus on submicron particles (PM1), in two major cities of Poland - Warsaw and Zabrze. These cities were selected due to their distinct levels of urbanization and industrialization. Non-carcinogenic and carcinogenic risks assessment was performed for children and adults. The carcinogenic risk was evaluated for As, Cd, Cr(VI), Ni, Pb, and Co, classified as carcinogens, the non-carcinogenic risk evaluation encompassed a broader range of metals, including V, Mn, Cu, Zn, and Mg, aiming to comprehensively understand health exposure. The results highlight elevated carcinogenic risk in Zabrze, primarily linked to industrial activities and ongoing emissions. Notably, Ni, As, and Cr(VI) exceed safe limits, underscoring the need for targeted interventions. Moreover, non-carcinogenic risks reveal Zabrze’s heightened respiratory health risks, compared to Warsaw. Despite Warsaw’s lower non-carcinogenic risk values, both cities recorded Ni and Mg concentrations exceeding safe limits. This indicates that Zabrze faces higher health risks from heavy metal exposure due to ongoing pollution sources. In contrast, Warsaw, the capital city and a major urban centre, demonstrates better air quality but still requires continuous monitoring and pollution control measures.

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.

The paper provides a concise review of key publications on particulate matter of aerodynamic diameter below 1 μm (PM1) having been published in Poland in the years 2007–2022. Data and conclusions related to the study of concentrations, chemical composition, and content of selected toxic and carcinogenic compounds in PM1 as well as methods and conclusions on the assessment of the origin of PM1 in various regions of Poland have been tabulated. The conclusions of this review attempt to outline the directions of further research that could prove crucial in obtaining information and filling the identified gaps in knowledge about PM1 in Poland. While this work may be theoretical, it can serve as a valuable and compact source material for research groups, organizations supervising and financing research, as well as those responsible for assessing air quality and mitigating negative health effects related to air quality.

The properties of particulate matter PM, including its impact on the environment and human health, depend mainly on the size (more precisely: size distribution) of the particles since the size is usually dependent on the processes/sources of the PM. This work presents the results of a one-year-long measurement campaign of PM. PALAS Fidas 200 from Airpointer air quality station was used. The PM was measured in Warsaw, Poland continuously from 1st May 2022 to 30th April 2023; size distribution was recorded with 120 s intervals and averaged in 3600 s periods. It was found, that the number and the mass size distribution varied depending on the averaging period (different hours of the day, different days of the week, and different months of the year). Additionally, the authors determined the periods of impact on selected sources (traffic emission, municipal emission, and industrial emission) on the number and mass size distributions of PM at the sampling site. Monitoring of number and mass size distributions of PM is a relatively easy and more cost-effective method than analysing the chemical composition of PM. Therefore, is crucial to develop a method of identifying sources of PM based on size distributions. It was found that such a method can be in the future as successful in source apportionment as in the analysis of chemical compositions.

Air pollution emissions from road vehicles majorly contribute to particulate pollution. This poses significant threats to the environment and human health. Road dust contains various potentially toxic elements, which, when exposed to humans, can lead to severe illnesses such as asthma, cardiovascular diseases, and cancer. This study assessed adult health risks through accidental ingestion, inhalation, and dermal contact associated with heavy metals (Cr, Cu, Ni, Pb, and Zn) in road dust (with a fraction size < 0.1 mm). The analysis covers areas between sound-absorbing screens (S), in open spaces without screens (F), and at highway/express exits (E) with different surfaces: asphalt (A) and concrete (C). Results indicate the highest health risk levels are associated with Zn in road dust in S and E areas, indicating its potential negative impact on human health. When comparing results for all metals, road dust collected from A surfaces might pose a greater health risk than C surfaces. The carcinogenic risk for Cr and Ni found in road dust collected from A and C surfaces at points S, F, and E is medium. The most significant carcinogenic risk (medium-high) is associated with Cr in road dust from A surfaces in the F area, whereas the lowest risk (low-medium) for both A and C surfaces is linked to Ni exposure in the S point. The contributions of Cr and Ni highlight the need to reduce emissions of these elements in areas surrounding heavily trafficked roads.

W celu przeprowadzenia badań zebrano miejski pył drogowy w siedemnastu punktach badawczych w sezonie wiosennym na terenie Dolnego i Górnego Śląska w Polsce. Są to regiony znane z podwyższonego poziomu zanieczyszczeń. Celem badań było określenie stężeń metali ciężkich w ekstraktach wodnych w obu regionach, co ma bezpośrednie przełożenie na zawartość tych metali w wodach powierzchniowych zasilanych spływami pochodzącymi z deszczu, oraz ocena toksyczności wymywanego pyłu miejskiego w odniesieniu do bakterii A. fischeri, co pozwoliło na ocenę wpływu spływów z obszarów miejskich na organizmy żywe. W wyniku badań stwierdzono, że ekstrakty wodne badanych próbek miejskiego pyłu drogowego wykazywały zróżnicowane stężenia metali ciężkich na badanych stanowiskach w obu regionach – na Dolnym i Górnym Śląsku, wskazując na istniejące zanieczyszczenie obu badanych obszarów oraz na ryzyko zanieczyszczenia wód wskutek spływu wód opadowych. Powodem tego zanieczyszczenia jest wzmożony transport miejski, przemysł oraz obecne odpady poprzemysłowe, a także sposób ogrzewania domów (niska emisja pochodząca ze spalania odpadów oraz węgla i drewna). Przeprowadzone badania toksykologiczne w odniesieniu do bakterii A. fischeri wskazują jednoznacznie na toksyczność ekstraktu wodnego pyłu miejskiego pobranego ze stanowisk K1 (Bytom), K2, K3 (tereny poprzemysłowe, Piekary Śląskie) na Górnym Śląsku oraz W1 (Wrocław, ul. Obornicka), W5 (Bielany Wrocławskie) i W6 (Wrocław, Most Grunwaldzki) na Dolnym Śląsku. Punkty K1, K2, K3 odznaczały się także podwyższonymi stężeniami większości badanych metali (Mn, Ni, Zn, As). W przypadku Dolnego Śląska punkty W1, W5 i W6 stężenia te nie były najwyższe w regionie, co sugeruje, że na toksyczność tych próbek mogą wpływać także inne związki obecne w pyle (np. WWA, dioksyny), których nie identyfikowano w tych badaniach. Jednakże, bazując na badaniach toksyczności oraz oznaczonych stężeniach metali, można jednoznacznie stwierdzić, że oba regiony są zanieczyszczone i istnieje wysokie ryzyko wpływu tych zanieczyszczeń na biocenozę wodną, a pewnie też na cały ekosystem.

In the presented study, urban road dust was collected at seventeen research points in the spring season in Lower and Upper Silesia in Poland. These regions are known for their elevated levels of pollution. The aim of the study was to determine the concentration of heavy metals in water extracts in both regions, which has a direct impact on the content of these metals in surface waters derived from rainwater runoff, and to assess the toxicity of urban dust on the basis the toxicity test with bacteria A. fischeri to allow making an evaluation of the impact of runoff for living organisms. It was found that the water extracts of the tested samples of urban road dust had different concentrations of heavy metals at the studied sites in both regions, in Lower and Upper Silesia, indicating the existing pollution of both areas and the risk of water pollution due to rainwater runoff. The reason of this pollution is increased urban transport, industry and the presence of post-industrial waste and house heating systems (low emissions from burning waste, coal and wood). The toxicological studies on bacteria A. fischeri indicate the toxicity of the water extracts of urban dust samples collected from K1 (Bytom), K2, K3 (post-industrial areas, Piekary Śląskie) sites in Upper Silesia and W1 (Wrocław, ul. Obornicka), W5 (Bielany Wrocławskie) and W6 (Wrocław, Most Grunwaldzki) sites in Lower Silesia. Sites K1, K2, K3 were also characterized by increased concentrations of metals (Mn, Ni, Zn, As). In the case of Lower Silesia, sites W1, W5 and W6 were not characterised by the highest concentrations of metals in the region, which suggests that the toxicity of these samples may also be affected by other compounds present in the dust (e.g. PAHs, dioxins) that had not been identified in these studies. However, based on the toxicity studies and the concentrations of metals, both regions are polluted and therefore the high risk of the impact of these pollutants on the aquatic biocenosis and probably on the entire ecosystem does exist.

Reducing the amount of waste disposed of in landfills requires treatment in specialised facilities. Potential threats that can arise both in waste processing and in its storage comprise a fire hazard. Waste fires hold a significant share of the total number of the largest fires in Poland. Fires in landfills and their treatment facilities are related to air quality since during a fire a large number of various pollutants is emitted into the atmosphere in a relatively short time. The paper discusses the impact of a fire taking place at a waste treatment facility on air quality, in which 300 Mg of municipal waste was burnt. Using the HYSPLIT package, the atmospheric dispersion of 23 selected organic and inorganic pollutants was determined and then analysed in GIS software. The concentrations were compared with reference values specified in relevant legal regulations. Of the 23 substances analyzed, the concentration levels were exceeded only for 6 substances at a distance of more than half a kilometre from the fire: benzo(a)pyrene, benzene, styrene, acetaldehyde, PM10, and NO2 . The substance with the greatest range as regards the reference concentration levels was benzo(a)pyrene, a compound with a proven carcinogenic effect, which indicates the importance of reducing landfill fires in the context of public health.

Zmniejszenie ilości odpadów składowanych na wysypiskach wymaga ich przetwarzania w wyspecjalizowanych zakładach. Wśród zagrożeń, które pojawiają się zarówno w przetwarzaniu odpadów, jak i ich składowaniu, znajduje się zagrożenie pożarowe. Pożary odpadów mają znaczący udział w ogólnej liczbie największych pożarów w Polsce. Podczas pożaru duża liczba różnych zanieczyszczeń jest emitowana do atmosfery w stosunkowo krótkim czasie, w związku z czym pożary odpadów są związane z jakością powietrza atmosferycznego. W pracy omówiono wpływ pożaru w zakładzie przetwarzania odpadów na jakość powietrza, w którym spłonęło 300 Mg odpadów komunalnych. Przy wykorzystaniu pakietu HYSPLIT wyznaczono dyspersję atmosferyczną 23 wybranych zanieczyszczeń organicznych i nieorganicznych, a następnie przeanalizowano ją w oprogramowaniu GIS. Stężenia porównano z wartościami referencyjnymi określonymi w odpowiednich aktach prawnych. Spośród 23 analizowanych substancji poziomy odniesienia zostały przekroczone tylko dla 6 substancji w odległości ponad pół kilometra od ognia: benzo(a)pirenu, benzenu, styrenu, aldehydu octowego, PM10 i NO2 . Substancją o największym zakresie, jeśli chodzi o poziomy stężeń referencyjnych, był benzo(a)piren, związek o udowodnionym działaniu rakotwórczym, co wskazuje na znaczenie ograniczenia pożarów składowisk w kontekście zdrowia publicznego.

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.

Strumienie rozproszone są powszechnie wykorzystywane m.in. do gaszenia, chłodzenia oraz absorpcji substancji niebezpiecznych. W celu zoptymalizowania procesu, w którym wykorzystywane są rozpylacze, niezbędna jest wiedza na temat mikroi makrostruktury wytwarzanych przez nie strumieni. Parametry mikrostruktury strumienia rozpylonego, takie jak średnia średnica kropel czy widmo rozpylenia są uzależnione zarówno od cech konstrukcyjnych dysz, jak również ilości i ciśnienia przepływającej cieczy W artykule przedstawiono wyniki badania mikrostruktury strugi generowanej przez wirową dyszę spiralną TF 6 NN o pełnym stożku zraszania. Badania były przeprowadzone przy różnych ciśnieniach zasilania i w czterech punktach strefy zraszania. Wybór tych punktów był poprzedzony wyznaczeniem rozkładów intensywności zraszania. Do określenia średnich średnic powierzchniowych kropel i widma rozpylenia wykorzystano metodę fotoelektryczną, zaś intensywność zraszania wyznaczono metodą kubełkową. Na podstawie przeprowadzonych badań udowodniono, że w strefie zraszania występują istotne dysproporcje w parametrach mikrostrukturalnych strumienia. Wykazano, że największa ilość wody wypływająca z badanej dyszy jest kierowana do głównego pierścienia zraszania, gdzie występują największe średnie średnice kropel. Zmiana ciśnienia zasilania dyszy nie powoduje istotnych zmian parametrów strugi w centralnej części strefy zraszania. W tym obszarze widmo rozpylenia, intensywność zraszania i średnia średnica kropel, niezależnie od ciśnienia zasilania, były zbliżone. Ponadto udowodniono, że w strefie położonej bezpośrednio pod dyszą odnotowuje się największy stopień rozpylenia strugi.

Dispersed streams are widely used for such purposes as extinguishing, cooling and absorbing hazardous substances. In order to optimise the process in which atomisers are used, it is necessary to understand the micro- and macrostructure of the jets they produce. The parameters of a spray jet microstructure, such as the average droplet diameter or the spray spectrum, are dependent on both the design features of the nozzles and the quantity and the pressure of flowing liquid. This paper presents the results of a study of the microstructure of a jet generated by the vortex spiral nozzle TF 6 NN with a full sprinkling cone. The research was executed at various supply pressures and in four points of the spray zone. The selection of these points was preceded by the determination of spray intensity distributions. The photoelectric method was used to determine the mean surface diameters of droplets and the spray spectrum, while the spray intensity was established using the bucket method. On the basis of the performed tests it has been proven that significant disproportions in the microstructural parameters of the spray occur in the sprinkling zone. It was shown that the tested nozzle directs the largest amount of water to the main spray ring, where the largest average droplet diameters occur. Changing the nozzle supply pressure does not cause significant changes in the spray parameters in the central part of the spray zone. In this area, the spray spectrum, spray intensity and mean droplet diameter were similar regardless of the supply pressure. Moreover, it has been proven that in the zone located directly under the nozzle there is the highest degree of spray jet atomisation.

Zanieczyszczenia obecne w pyle drogowym, pochodzące z ruchu ulicznego takie jak WWA i inne związki organiczne czy metale ciężkie, są wymywane wraz z deszczem i dostają się do wód, ostatecznie kumulując się w osadzie dennym na wiele lat, tym samym zagrażając organizmom wodnym oraz istotnie wpływając na jakość wód. Aby zbadać wpływ tych związków na zdrowie organizmów żywych, nie wystarczą tylko rutynowe badania chemizmu wód i badania osadów dennych, ponieważ do tego celu bardziej nadają się organizmy żywe. Z tego powodu chcąc poznać reakcję na tego typu zanieczyszczenia organizmów żywych, do badania toksyczności pyłów drogowych spłukiwanych z dróg po raz pierwszy w Polsce zastosowano test toksyczności chronicznej OSTRACODTOXKIT F™, który polega na obserwacji rozwoju Heterocypris incongruens naturalnie występującego w osadach dennych. Małżoraczki H. incongruens wykorzystane w badaniach są bardzo wrażliwe na zanieczyszczenie metalami ciężkimi, stanowią zatem odpowiednie narzędzie do badania toksyczności pyłu drogowego wymywanego do fazy wodnej. Badania prowadzono w aglomeracji wrocławskiej (w centrum miasta i na przedmieściach), na stanowiskach różniących się intensywnością ruchu drogowego. Stwierdzono, że pył drogowy ma istotny wpływ na zahamowanie wzrostu oraz żywotność małżoraczków, ponieważ na obszarach o dużym natężeniu ruchu drogowego ich śmiertelność była bardzo duża, co korespondowało z podwyższonymi poziomami stężenia badanych pierwiastków na tych stanowiskach badawczych. Z kolei pył drogowy zebrany na przedmieściach Wrocławia nie powodował śmiertelności małżoraczków i tylko nieznacznie wpłynął na ich rozwój. Podsumowując, stwierdzono, że test toksyczności chronicznej OSTRACODTOXKIT F™ jest odpowiednim narzędziem do badania wpływu pyłów drogowych na ekosystem wodny.

The application of OSTRACODTOXKIT F™ test to assess metals contamination in road dust in Wrocław agglomeration. Pollutants present in road dust deriving from trafﬁ c, such as PAHs and other organic compounds or heavy metals, are washed out with rain and get into the water bodies accumulating in sediments for many years and simultaneously posing a threat to aquatic life and signiﬁ cantly affecting water quality. To study the impact of these toxic compounds on the health of living organisms, routine tests of water and sediments chemistry are insufﬁ cient as studies based on living organisms are much more reliable. And therefore, in order to know the response of living organisms to road dust pollutants which enter the water bodies the chronic toxicity test OSTRACODTOXKIT F™ was used. This test is based on the observation of development of Heterocypris incongruens that normally lives in sediments. Ostracod, H. incongruens is very sensitive to heavy metal contamination, thus it is a very good tool to study toxicity of road dust washed out with rain into the water bodies. The research was conducted in the Wrocław agglomeration (in the city centre and suburbs) at sites differing in the intensity of car trafﬁ c. We observed that road dust had a signiﬁ cant effect on growth inhibition and death of ostracods, as highest growth inhibition and mortality in the busy areas occurred which also corres ponded with highest concentrations of studied elements at these sites. On the other hand, road dust collected in the suburbs of Wrocław did not cause death of H. incongruens and only slightly affected their development. In conclusion, we can state that the chronic toxicity test OSTRACODTOXKIT F™ is a suitable tool to study the impact of road dust on the aquatic ecosystem.

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.

The mass size distribution of five fractions of particulate matter inside most popular types of closed sports facilities before and after athlete training were compared. In all the facilities, the concentrations of particles were higher during the training than before it. Their values depended on the type of flooring and cubic capacity of the rooms. Particle mass size distribution importantly affects the particle deposition rate in the respiratory tract. The results of the work indicate the necessity of further investigating the relations between the physical properties of particles and the effects of inhaling them during training in various sports facilities.
