Opis:
Air pollution is the result of natural processes and intense urban development. The undesired emission of volatile substances causes environmental threats such as acid rains, aggravated greenhouse effect or the ozone depletion. Moreover, the pollution released into the air is harmful to the human respiratory system, eyes and skin. This paper presents the body of analyses conducted in Poznań between 2015–2017 on the changes in the local emission concentration of PM10 and PM2.5. The data concerning the emission of suspended particulates were provided by the meteorological station on Polanka St. in Poznań. The research included a correlation analysis. The results point to a steady decrease in the amount of produced particulates. It was also noted that the emissions of PM10 and PM2.5 change seasonally, with the highest levels in the autumn and winter. Furthermore, the amount of emitted suspended particulates is correlated with the temperature; hence, it is supposed that the main source of air pollution in Poznań involves low-efficiency heaters and boilers.

Opis:
Due to its irritating, allergenic, toxic, pathogenic, and carcinogenic effects, suspended particulate matter (PM) seriously threatens human health. Therefore, it seems obvious to control the level of concentration of PM2.5 and PM10 particles and their reduction in the indoor environment such as homes, workplaces, or public utilities. In the following work, an attempt was made to determine the efficiency of a home air purifier based on the concentration of PM2.5 and PM10 particles at selected measurement points in a teaching room located in the building of the Bialystok University of Technology. The tests were carried out in March and in April 2021, using the DT-96 meter, which measured the concentration of PM2.5 and PM10 in the air. The study included the time and intensity of air purifier operation. In addition, reference was made to the concentration of PM2.5 and PM10 in outdoor air, which was measured at measuring stations in the city of Bialystok. The obtained test results made it possible to assess the initial state of air quality in the test room, as well as to determine the parameters affecting the best efficiency of the air purifier and to notice the dependencies in changes in the concentration of PM2.5 and PM10 between the indoor and outdoor environment.

Opis:
The objective of the work was to determine the influence of selected meteorological elements on the concentration of PM10 and PM2.5 in the air as well as arsenic, cadmium, lead and benzoapirene contents in PM10. The work is based on the data collected by the automatic measurement station located on ul. Konarskiego, Siedlce, in 2013-2017. ANOVA demonstrated that the heavy metal content throughout the year was significantly influenced by the month of the year. The lowest concentration of arsenic was recorded from May to August, and cadmium from January to March as well as from October to December. Similarly to cadmium, the lead content was the highest in the winter months (from October to March). The analysis of correlation revealed that air pollution was predominantly affected by air temperature, wind speed and air humidity. The relationship between the air temperature and pollutant content was negative. As the temperature increased, arsenic, cadmium, lead, benzoapirene and the PM10 contents declined. It was found that an increase in wind speed contributed to a significant decline in the concentration of PM10 and PM2.5. Moreover, wind speed affected the heavy metal content. Relative air humidity influenced the metal concentration from November to May, whereas an increase in wind speed contributed to a significant decline in the concentration of only PM10 in the period from January to November.

Opis:
The present state of air quality is determined according to emission and imission situation of basic pollutants. According to the obtained information about the state of air quality, the development of imission and emission presently exhibits a decreasing tendency caused especially by industrial production innovations in European countries, with slight rises in renewable energy sources for electricity production, but especially the effort to improve the condition relates to the use of mandatory quotas and pollution charges in the European Union. The aim of the this article is to review the emission development in the year 1998 up to 2013 for Central European countries – Slovakia, Czech Republic and Poland and their comparison to the European average value of the released emission. The NOx and particulate matter PM10, PM2,5 were evaluated as pollutants, which over the last few years have contaminated the air and in particular the main environment.

Opis:
In this study, we investigate the changes in the concentrations of suspended particulate matter (PM10 and PM2.5) and selected gaseous pollutants (VOCs, H2S) in the atmospheric air inside and outside a 9-story building, which is intended primarily for the teaching activities. The purpose was to determine whether the air quality inside the building is directly dependent on the outside air quality. The analysis also included the influence of the height of the building, its location and environment, as well as meteorological conditions. No clear correlation was found between the measured parameters inside and outside the building. The height above ground (the floor on which the measurements were made) was found to have a significant influence on the concentration of each pollutant. Wind direction was also found to have a very important impact on the air quality inside the building. A strong relationship was observed on the leeward side between the concentration of impurities on the inside and outside of the building.

Opis:
The paper considers the current problem of improving the quality of atmospheric monitoring. The paper aimed at conducting a monitoring section of the existing situation in the studied territories in St. Petersburg. The following study methods were described: gravimetric, electrochemical, and chromatographic. The analysis of samples was carried out on the following laboratory facilities of the mobile environmental laboratory: PU-3E aspirator, ECOLAB portable gas analyser, DUSTTRAK 8533 dust analyser, portable gas chromatograph FGKh-1, professional weather station. The study consisted of two parts and was carried out in two districts of the city: Novosmolenskaya Embankment of the Smolenka River (Vasileostrovsky District) and the banks of the Volkovka River (Frunzensky District). As a result of the study, the concentrations of nitrogen dioxide, carbon oxide, suspended solids and volatile organic compounds in the air of the studied districts were measured. The obtained values were compared with the maximal single limiting concentration (LMCm.s.) and assumptions were made about the possible sources of pollution. In the territory of Novosmolenskaya Embankment, the concentration of nitrogen dioxide varied from 0.211 mg/m3 to 0.472 mg/m3, which means the exceedance of LMCm.s. The maximum permissible concentration of the volatile organic compounds (VOC) content in air was exceeded by several orders of magnitude. No exceedance of LMCm.s. was detected for the content of carbon oxide and suspended solids in the air. The empirical data was used to build the air pollution content maps and to calculate the atmospheric pollution index in the studied territory.

Opis:
Zjawisko zanieczyszczenia pyłem zawieszonym PM10 i PM2,5 występuje w dużych aglomeracjach miejskich, gdzie głównym źródłem ich obecności jest komunikacja, co wiąże się przede wszystkim ze spalaniem paliw płynnych. Celem badań była ocena stanu zanieczyszczenia powietrza pyłem PM2,5 i PM10 dla wybranego obszaru miasta Bydgoszcz. Analizę przeprowadzono, wykorzystując dane pochodzące ze stacji monitoringu powietrza zlokalizowanej przy ul. Poznańskiej. Stacja jest własnością Wojewódzkiego Inspektoratu Ochrony Środowiska (WIOŚ) w Bydgoszczy. Badania wykazały, że najwyższe średnie dobowe stężenie pyłu wystąpiło w piątki i wynosiło odpowiednio 27,6 μg/m3 dla PM2,5 i 44,46 μg/m3 dla PM10. Zaobserwowano tendencję występowania wyższych wartości stężeń w sezonie grzewczym. Stwierdzono, iż średnie roczne stężenie pyłu zawieszonego (PM2,5 i PM10) w aglomeracji bydgoskiej jest bliskie przekroczenia poziomu dopuszczalnego ze względu na ochronę zdrowia ludzi.
The phenomenon of suspended particulate pollution PM10 and PM2.5 occurs in large urban areas where the main source of their presence is communication, which is primarily related to the combustion of liquid fuels. PM2.5 dust pollution is a major risk factor for diseases of the respiratory, cardiovascular, and allergy. Act regulating the standards and target dates for reducing concentrations of particulate matter in urban areas and in all the cities of over 100 thousand. residents of the Directive of the European Parliament and Council Directive 2008/50/EC of 21 May 2008. on ambient air quality and cleaner air for Europe (CAFE). The acceptable level of average daily concentration of PM10 is 50 μg/m3 and may be exceeded by not more than 35 times a year, while the level of allowable annual average concentration of 40 μg/m3. The aim of this study was to assess the state of air pollution of dust PM10 and PM2.5 for the selected area of the city of Bydgoszcz. The analysis was conducted using data from air monitoring stations located at Poznanska street. The station is owned by the Provincial Inspectorate for Environmental Protection (VIEP) in Bydgoszcz. The studies have shown that the annual average concentration of particulate matter analyzed station in Bydgoszcz in the years 2013–2015 amounted to PM10 41 μg/m3 PM2.5 and 23 μg/m3. The results are on the borderline of acceptable levels of concentration resulting from the Regulation of the Minister of the Environment of 2 August 2012. The concentrations of particulate matter in ambient air are strongly associated with meteorological conditions. The definitely higher concentrations observed in the autumn-winter season. The decrease in temperature causes the combustion in the boiler house of fuels with a high emissions. The highest average daily concentration of suspended particulate matter was observed on Thursday and Friday in the winter months, and while the lowest concentration was recorded in the summer months.
