Opis:
Air pollution is the reason for huge damages to European Union citizens’ health. Every year, some 400,000 Europeans die prematurely as a result of excessive levels of such substances as suspended dust, nitrogen dioxide and ozone. It is despite the fact that the EU legal regulations on the permissible values of air pollutants have been in force for almost thirty years. In order to broaden the knowledge of air pollution as well as the ways to implement and the effectiveness of the policy on air protection in individual Member States, the Supreme Audit Office and the Netherlands Court of Audit coordinated the largest international audit in the field of environmental protection in the history of the European Organisation of Supreme Audit Institutions – EUROSAI. The audit resulted in a joint audit report on air quality, based on the findings of the audits conducted in the countries that participated in this project.

Opis:
It is important to indicate air quality level in metropolitan areas as it is harmful to public health. Air quality index (AQI) is a useful tool to convert air quality pollutants concentrations into a single number representing air quality level. There are many air quality index models in the literature to represent air quality level. Two models were selected to assess the air quality in Mosul city. The first model utilizes the highest sub-index depending on USEPA pollutants standards. The second model includes the weights of all pollutants in the model as an aggregated air quality index (AAQI) model. Air quality concentrations were collected using a fixed monitoring station located in the courtyard of the public library for a year. The results illustrate that the values of aggregated Air quality index model were higher than those of the USEPA model. Air quality category "Moderate" was dominant in winter and spring for the two models. In contrast, the category "Unhealthy for sensitive group" was dominant in summer and autumn. Furthermore, the category "Unhealthy" appeared only with aggregated model in autumn. The contribution of air pollutants in AQI can be ranked as PM10, SO2, NO2, CO and O3 from higher to lower. The study concluded that the AAQI is comprehensive and more workable in environmental management.

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.

Recent studies and reports on cleanliness and quality of air indicate that Poland belongs to a group of European Union countries where air pollution is at one of the highest levels. Low air quality in many areas of Poland should be considered not only in the context of environmental destruction, but also in the context of the developmental negligence of the country in the context of the care of ecology. This article summarizes the results of research into the scale of threats regarding air quality occurring locally in the city of Słupsk. The paper also discusses the scale of air pollution-related risks and their consequences for the life and health of the individual.

Cigarette smoking are the most important reasons for increased carbon monoxide (CO) level in exhaled air. During the experiment, the CO level in indoor air in room was measured. Outdoor air quality data including atmospheric CO concentration, obtained from the own measured and data from the weather platform “freemeteo”. The measurements were carried out with the following variants: outside air, a room ventilated without people, nonsmokers, smokers and non-smoking people, smokers entering the room after smoking cigarettes, smokers who smoke in the room. As proven by measurements, carbon monoxide carried in the lungs by smokers has low concentrations and should not threaten the health of non-smoking users of rooms. The maximum concentration of carbon monoxide in the room was 1.4 ppm. In the external air, the average concentration of carbon monoxide was exactly as much as reported in the literature – 0.3 ppm.

Opis:
The article focuses on the problem of air pollution, which is referred to as smog, which, according to the WHO, causes the death of 4.2 million people annually. In Europe, the problem of smog particularly affects Poland, according to WHO data, among the 50 most polluted European cities, as many as 33 are in Poland. Out of concern for the health of the residents, Polish law has given local authorities the opportunity to introduce anti-smog resolutions. Anti-smog resolutions focus mainly on reducing dust emissions from the municipal and housing sector, and according to the data of the National Centre for Balancing and Emissions Management, it is responsible for approximately 49% of dust emissions into the atmosphere in Poland. Małopolska also adopted anti-smog resolutions in 2016 (for the city of Kraków) and 2017 (for the remaining area of the voivodeship). Nevertheless, actions under the implementation of air protection programs in Małopolska have been undertaken much earlier. In the years 2013–2018, 43.6 thousand boilers and stoves using solid fuels were decommissioned in Małopolska, including 22.5 thousand in Kraków alone. The article analyzes the changes in air quality in Małopolska in the years 2012–2020. The data analysis focused on five basic pollutants included in smog (i.e. PM10 and PM2.5 dust, nitrogen oxides, sulfur dioxide and carbon monoxide) and the readings of 8 air quality monitoring stations (3 located in the city of Krakow and 5 stations located outside Krakow). The main purpose of the analysis was to show whether the measures taken in Małopolska lead to the improvement of air quality. For this purpose, both changes in daily average and annual average pollutant concentrations recorded by individual measurement stations, as well as changes in the number of days in the heating season in which the limit values were exceeded were analyzed. The analysis of the available measurement data for the years 2012–2020 clearly showed that there are pollutants for which the permissible content in the air is exceeded many times a year throughout the voivodeship. At the same time, in the analyzed period, there are noticeable decreasing trends in the observed concentrations of individual pollutants in the air, which proves that the measures taken in Małopolska to improve air quality are slowly bringing results.

Air pollution regards all chains of environmental prospective. As an actualized and future issue we concentrate our efforts to set a frame on major air pollutants and their relation. The period of study rely on 15 year time interval (2012-2016) and the geographical area is focused on data retrieved from the capital, Tirana. We canalize our investigation mainly on inhalable particle and their behavior toward other particles. The goal is to establish $PM_{10}$ (Particulate Matter with a diameter < 10 μm) trend based on significant associations. We develop the analytical process due to air pollution numbers which turn to be of considerable concern in the country. $PM_{10}$ and Total Suspended Particulate Matter (TSPM) have different diameter but reflect the same trend line. They show strong positive correlation value with $O_3$ and $SO_2$ (r > 0.75). $NO_2$ particles seem to be less (r < 0.25) involved in this interaction. AQI (Air Quality Index) is fully depended (r > 0.92) on $PM_{10}$ behavior. We test also socioeconomic and meteorological parameters that produce interesting results. IDW (Inverse Distance Weight) interpolation maps resume the geographical dispersion of $PM_{10}$ values. The reductive emission index retrieved from Euro standard transition for vehicle fleet develops a new situation. We generate potentially future values of $PM_{10}$ emission. Predictive scenario is created, interpolation maps are the backbone of this methodology.

Introduction. Kraków is one of the most beautiful but also one of the most crowded Polish cities with large numbers of cars, pedestrians and cyclists travelling each day. There has been an increasing concern about the human exposure to bioaerosols, which can occur, among others, at the sites characterized by increased dustiness, such crowded streets. The aim of this study was to evaluate the microbiological quality of air in the selected sites situated by the main roads in Kraków. Material and methods. Air samples were collected in 10 sites located by the main roads, using a MAS-100 impactor four times per year. Four microbial groups were enumerated: mesophilic bacteria, fungi, actinomycetes and staphylococci. The results were expressed as colony forming units per m3 of air and compared with Polish Standards concerning microbiological air quality. Results. The greatest bacterial and fungal aerosol concentration was observed in autumn, when atmospheric conditions could have promoted abundance of those microorganisms. In general, fungi were the most numerous group of airborne microorganisms, while staphylococci were the least numerous. The number of actinomycetes was alarmingly high in all sites. It was found that seasonal differences in the bioaerosol concentration were statistically significant and the recorded differences could have been affected by atmospheric conditions. Conclusions. The conducted studies showed that in terms of airborne bacteria and fungi, the air in the examined locations was microbiologically unpolluted. However, high numbers of airborne actinomycetes were observed in all sites, which can cause adverse health effects in pedestrians or cyclists who are frequently exposed to bioaerosols by the main routes in Kraków. Statistically significant variability was found in the prevalence of the examined microorganisms in different seasons of the year.
Wstęp. Kraków jest jednym z najpiękniejszych i zarazem jednym z najbardziej zatłoczonych polskich miast, w którym każdego dnia po ulicach przemieszczają się tysiące samochodów, a także przechodniów i rowerzystów. Coraz większe zaniepokojenie budzi problem narażenia ludzi na aerozol biologiczny, którego podwyższone stężenie może wystąpić między innymi w zapylonych miejscach, takich jak zatłoczone ulice. Z tego powodu, celem badań była ocena jakości mikrobiologicznej powietrza w wybranych punktach przy głównych szlakach komunikacyjnych Krakowa. Materiał i metody. Próbki powietrza pobierano w 10 punktach umiejscowionych wzdłuż głównych dróg, czterokrotnie w ciągu roku, przy użyciu impaktora MAS- 100. Oznaczono liczebność czterech grup mikroorganizmów – bakterii mezofilnych, grzybów, promieniowców i gronkowców. Wyniki wyrażono jako jednostki tworzące kolonie w m3 powietrza i porównano z Polskimi Normami dotyczącymi jakości mikrobiologicznej powietrza atmosferycznego. Wyniki. Najwyższe stężenie bioaerozolu bakteryjnego i grzybowego stwierdzono jesienią, gdy warunki atmosferyczne były korzystne dla zwiększonej liczebności drobnoustrojów w powietrzu. Ogółem, grzyby były najliczniejszą grupą drobnoustrojów, a najmniej liczną były gronkowce. We wszystkich badanych lokalizacjach liczebność promieniowców była niepokojąco wysoka. Stwierdzono istnienie istotnej statystycznie zmienności sezonowej w stężeniu bioaerozolu, przy czym różnice te mogły być wynikiem zmiennych warunków atmosferycznych. Wnioski. Przeprowadzone badania wykazały, że pod względem stężenia bakterii i grzybów powietrze w badanych lokalizacjach było mikrobiologicznie czyste. Jednakże we wszystkich lokalizacjach stwierdzano wysokie stężenie promieniowców, co może prowadzić do niekorzystnych skutków zdrowotnych np. u pieszych i rowerzystów, którzy często narażeni są na kontakt z bioaerozolem, podróżując wzdłuż głównych dróg w Krakowie. Stwierdzono istotną statystycznie zmienność liczebności badanych drobnoustrojów w różnych porach roku.

The objective of the study was to characterize the mycological quality of air at animal veterinary practice in Krakow. Bioaerosol measurements were performed during the summer season of 2017. The samples of outdoor and indoor air at animal veterinary practice were collected using a 6-stage Andersen`s air sampler. The highest concentration of fungal aerosol was observed in the treatment room. The analysis showed various fungal contamination in different measuring points at different measuring times of the day. Based on the analysis of bioaerosol particle size distribution it was found that the largest "load" of fungi, isolated form the air, can reach (in the human respiratory tract) to the region of the throat, trachei and primary bronchi. The predominant fungi in indoor air was Penicillium spp. and Cladosporium cladosporoides. Fungi that can cause dermatophytoses have also been isolated from indoor air: Microsporum canis and Trichophyton verrucosum. The study confirmed that the animal veterinary practice can be a workplace related to exposure to microbial agents.

Opis:
Wastewater treatment plants (WWTPs) have been recognized as a source of odors and microbial pathogens to the outdoor air. The results of many studies revealed that high amounts of microorganisms are not only present in the stream of wastewater or sludges but also in the bioaerosols that are generated during the different stages of the wastewater treatment. Hence, possible migration of biological contaminants into the interiors cannot be excluded. However, there is a knowledge gap in an assessment of the microbiological indoor air quality of the facilities located at WWTPs. The aim of this study was to evaluate the level of outdoor microbial air contamination upon the indoor environment based on the determined outdoor to indoor (O/I) ratios. The sampling of airborne bacteria and fungi was conducted in three replications with the sedimentation and impaction method, during a one-year survey in ten technological and office buildings as well as their vicinity, at the municipal wastewater treatment plant of Lublin (Poland). Moreover, the cleanliness of hand contact surfaces in staff rooms was examined (Rodac plates). Additionally, API identification of bacteria and fungi was carried out. The highest concentration of total bacteria count (3617 CFU/$m^3$) and fungi in bioaerosols (5386 CFU/$m^3$) was detected in the air around the sewage pumping station, close to the aeration tanks. P. fluorescens was found in the air around the grit chamber (78 CFU/$m^3$). The majority of the examined indoor air samples were characterized with different levels of microbiological contamination – from non-polluted to moderately polluted. The number of total bacteria counts ranged from 180 to 4679 CFU/$m^3$. The highest estimated indoor fungi concentration was 4022 CFU/$m^3$. The controlled surfaces were mostly contaminated with the Actinomycetes and Coliform bacteria. No Salmonella sp. were detected. The bacteria from the Enetrobacteriaceae family were commonly isolated from the indoor and outdoor air samples. The obtained data can be used to devise further guidelines facilitating control and management of WWTP to avoid or minimize the staff exposure.

Powiat Kędzierzyn-Koźle jest jednostką administracji terytorialnej i samorządowej województwa opolskiego, w południowo-zachodniej Polsce. Istniejąca w Kędzierzynie-Koźlu sieć monitoringu powietrza obejmuje dziś tylko jedną w pełni automatyczną stację monitoringu. Emisja wielu zanieczyszczeń powietrza w Kędzierzynie-Koźlu zmniejszyła się znacząco od 1992 r., jednak od 2007 r. stężenie NO2 i pyłu zawieszonego PM10 w powietrzu się nie zmniejszyło. Zmniejszenie stężenia zanieczyszczeń powietrza jest nadal konieczne. Prognozowanie jakości powietrza to jeden z kluczowych elementów współczesnego zarządzania jakością powietrza. W artykule przedstawiono modele i prognozy stężenia SO2, NO2, CO, O3 i PM10, skonstruowane na podstawie danych, pozyskanych z automatycznej stacji monitoringu w Kędzierzynie-Koźlu.
Kędzierzyn-Koźle County is a unit of territorial administration and local government in Opole Voivodeship, south-western Poland. The existing air monitoring network in Kędzierzyn-Koźle comprises only one fully automatic monitoring station now. In Kędzierzyn-Koźle, emissions of many air pollutants have substantially decreased since 1992. However, since 2007, measured concentrations of NO2 and particulate matter PM10 in the air have not shown any improvement. The need to reduce air pollution still remains an important issue. Air quality forecasting is one of the core elements of contemporary air quality management. This paper presents models and forecasts of SO2, NO2, CO, O3 and PM10 concentrations based on data from automatic monitoring station in Kędzierzyn-Koźle.

Opis:
Four years of observations of radon, meteorology and atmospheric pollution was used to demonstrate the efficacy of combined diurnal and synoptic timescale radon-based stability classification schemes in relating atmospheric mixing state to urban air quality in Zgierz, Central Poland. Nocturnal radon measurements were used to identify and remove periods of non-stationary synoptic behaviour (13–18% of each season) and classify the remaining data into five mixing states, including persistent temperature inversion (PTI) conditions, and non-PTI conditions with nocturnal conditions ranging from well mixed to stable. Mixing state classifications were performed completely independently of site meteorological measurements. World Health Organization guideline values for daily PM2.5/PM10 were exceeded only under strong PTI conditions (3–15% of non-summer months) or often under non-PTI stable nocturnal conditions (14–20% of all months), when minimum nocturnal mean wind speeds were also recorded. In non-summer months, diurnal amplitudes of NO (CO) increased by the factors of 2–12 (3–7) from well-mixed nocturnal conditions to PTI conditions, with peak concentrations occurring in the morning/evening commuting periods. Analysis of observations within radon-derived atmospheric mixing ‘class types’ was carried out to substantially clarify relationships between meteorological and air quality parameters (e.g. wind speed vs. PM2.5 concentration, and atmospheric mixing depth vs. PM10 concentration).

Opis:
Najczęściej w przedszkolach człowiek zaczyna swoją edukację. Dzieci spędzają w nich od pięciu do dziesięciu godzin dziennie. Dlatego ważna jest jakość powietrza wewnętrznego. Najczęściej stosowanym systemem wentylacji w przedszkolach jest wentylacja naturalna. Dokładniej wentylacja grawitacyjna kanałowa wspomagana okresowym wietrzeniem. W badanym przedszkolu rano stężenie dwutlenku węgla nie przekracza dopuszczalnych norm. Po południu stężenia dwutlenku węgla są znacznie przekroczone - maksymalnie o 190%. Temperatura i wilgotność powietrza znajdują się w granicach normy. Rozszczelniając lub otwierając okna doprowadzamy do pomieszczeń powietrze zewnętrzne, poprawiamy w ten sposób działanie wentylacji grawitacyjnej, poprawiamy jakość powietrza wewnętrznego.
Formal education usually begins in kindergarten. Children spend five to ten hours a day there, so indoor air quality is of paramount importance. Natural ventilation (or to be more precise gravitational channel ventilation system) is by far the most common ventilation method in kindergartens; its efficiency is enhanced by airing the premises from time to time. In the kindergarten in question, carbon dioxide concentration in the morning does not exceed the permissible level. In the afternoon, however, this level is considerably exceeded (by as much as 190%). Temperature and humidity stay within the acceptable range of values. Thanks to unsealing or opening the windows, outdoor air penetrates into the rooms, which boosts the functioning of the gravitational ventilation system thus improving indoor air quality.
