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.

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.

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.

Opis:
As part of the European Public Health project IMCA II validity and practicability of “air pollution” as a respiratory health indicator were analyzed. The definitions of air quality as an indicator proposed by the WHO project ECOEHIS and by IMCA I were compared. The public availability of the necessary data was checked through access to web-based data-bases. Practicability and interpretation of the indicator were discussed with project partners and external experts. Air quality serves as a kind of benchmark for the good health-related environmental policy. In this sense, it is a relevant health indicator. Although air quality is not directly in the responsibility of health policy, its vital importance for the population’s health should not be neglected. In principle, data is available to calculate this IMCA indicator for any chosen area in Europe. The indicator is relevant and informative, but calculation and interpretation need input from local expert knowledge. The European health policy is well advised to take air quality into account. To that end, an interdisciplinary approach is warranted. The proposed definition of air quality as a (respiratory) health indicator is workable, but correct interpretation depends on expert and local knowledge.

Opis:
Polybrominated diphenyl ethers (PBDEs) are additive flame retardants which have found applications in polymers for many consumer plastic and electronic goods. Wide use of these chemicals has led to their extremely high concentrations in the indor environments. This paper presents an exploratory study of the photodebromination of five individual lower polybrominated diphenyl ether congeners (BDE-28, BDE-47, BDE-99, BDE-100 and BDE-101) irradiated with white light and different UV (A, B, C) light ranges. The capability of photodegradation of lower PBDEs under room lights was proven by the debromination which occurred with various effectiveness for the selected PBDE congeners and depended of light source. Almost all PBDE congeners showed the greatest decay when exposed to UV-C, with the exception of BDE-100. The decay of irradiated congeners occurred rapidly during the first 5 min of experiment. The final degradation varied from 38% decay (BDE-28, UV-C) to 94% (BDE-47, UV-C). These findings can help in predicting PBDE behavior in indoors and also be useful in the design of PBDE remediation processes.

Opis:
The aim of the research is to identify places with deteriorated air quality in the selected city. After an analytical analysis of the data, it is possible to propose steps that can be used to actively contribute to the reduction of air pollution, especially due to road traffic. Places where deteriorated air quality was identified were identified on the basis of practical measurements. Given that the measurement route was designed in a built-up area of the city with a large number of pedestrians, the research was primarily focused on the identification of particulate matters (PM) and the concentration of carbon monoxide CO. The measurements were performed repeatedly on a pre-defined route. The measurements were carried out repeatedly during the morning rush hour when traffic was congested on the roads. Based on the processing and evaluation of the measurements, the sections where increased values of individual emissions were recorded were determined. In this way, it is possible to precisely identify places where air quality deteriorates. The research conclusions provide support for planning the optimization of air quality management policies towards the creation of sustainable cities. The research results present the possibilities of identifying problematic sections from the point of view of emissions production. Critical places with regard to the production of emissions can be connected to places where a permanently increased movement of vehicles is observed.

Opis:
Air pollution is one of the greatest public health threats worldwide. All substances appearing in excessive quantities in the atmosphere, such as particulate matter, nitrogen oxides or sulphur oxides may be its ingredients. Depending on their size and nature, these compounds may cause greater risk of suffering from respiratory or cardiovascular diseases for exposed people as well as exacerbation and increased mortality due to these illnesses. Smaller particles may penetrate the brain’s blood barrier and thus affect the central nervous system. In many studies, they have been shown to have negative effects on brain structure, like diminishing white matter or neuronal degeneration, leading to the earlier onset of Alzheimer or Parkinson disease. Nevertheless, there are reports of association of air pollution with mood disorders, depression, and even suicide. There are many risk factors for these conditions, most important of which are the social situation or chronic diseases. However, it has also been confirmed that the environment may affect mental health. This article will present experimental, clinical and epidemiological studies on exposure to air pollution and its impact on depressive disorders and suicide. Our goal is to determine the relationship between air pollution and incidence of depression and suicides. Int J Occup Med Environ Health 2018;31(6):711–721

Opis:
Nowadays, one of the most important and essential aspects of having a healthy and safe life is the air safety and its quality in indoor and outdoor environments. In the air, there are not only chemical pollutants but also biological ones, with specific impacts. Hospital environments are among the most likely to be affected by the microbiological contamination of the air; therefore its quality is particularly important. Pathogenic microorganisms, which may be present in the air, can cause nosocomial infections in hospitalized patients, with compromised immune system or other medical conditions. This paper reflects the evaluation of microbiological air contamination, in different hospital environments and nearby areas, in the city of Tirana. The microbial air quality has been monitored during the period of 2009–2018, performing evaluations every three years, in the same area and the same time of the year. In order to build a database for understanding the impact of developmental changes on the air microbiological loads, results of similar studies conducted earlier, during 2007 and 2008 were also taken into consideration. The above-mentioned period was selected because of the changes in the infrastructure and indoor environments of the monitored area, where many patients have been treated for years. Changes have been made over the years to hospital structures and surroundings, including recreational facilities, clinical service units, as well as main and connecting roads, etc. The obtained results, which were compared over the years, provided a clear view of the changing microbiological air loads, influenced by the improvements of indoor and outdoor areas. The morphological studies of the observed, isolated, purified and identified microorganisms revealed the presence of specific mold loads, with the dominance of the species of Aspergillus genus and those of the group Fungi imperfecti. Over the years, a decrease in the total number was observed (from 103 to 101), together with a smaller number of bacteria (1012), in the monitored environments.

Objectives: The present study was aimed at evaluating microbiological contamination of air in Ciechocinek and Inowrocław – Polish lowland spa towns. Additionally, the impact of open-air inhalatoria on the quality of air was evaluated. Material and Methods: Air samples were collected seasonally in the urban areas, in the recreation areas and in the vicinity of inhalatoria in both towns using impaction. The numbers of mesophilic bacteria, staphylococci, hemolytic bacteria and actinomycetes were determined on media according to the Polish Standard PN-86/Z-04111/02. The number of moulds was determined on media according to the Polish Standard PN-86/Z-04111/03. Results: While the highest numbers of microorganisms were noted at the sites located in the urban areas, the lowest numbers were noted in the vicinity of the open-air inhalatoria. In all the investigated air samples the values of bioaerosol concentrations were below the recommended TLVs (≤ 5000 CFU×m⁻³ for both bacteria and fungi in outdoor environments). Location of the sampling site was invariably a decisive factor in determining the number of microorganisms in the air. Conclusions: The aerosol which is formed in the open-air inhalatoria has a positive influence on microbiological air quality. Owing to a unique microclimate and low air contamination, Ciechocinek and Inowrocław comply with all necessary requirements set for health resorts specializing in treating upper respiratory tract infections.

Managing the natural environment in the city is an important element of city management. Smart city authorities should take into account the opinion of residents about the comfort of living in the urban environment management strategy. A very important element of the natural environment in the city is air quality, which significantly affects the comfort of living in the city. The article presents surveys of opinions of the residents of a selected city in Silesia in Poland. The respondents' knowledge on the sources of air pollution in the city, the perceived health effects resulting from polluted atmospheric air and the expectations of residents towards the city authorities were examined using the anonymous questionnaire method. Residents' behavior in the situation of increased air pollution was also examined. On the basis of surveys, prophylactic pro-ecological activities were identified with the highest degree of acceptance of the local community as potential directions of urban environment management. The implementation of such activities, taking into account the opinions and preferences of the residents, is part of the co-management of the intelligent city.

Opis:
The objective of this study is to control the air quality parameters for a selected range of different particulate matters. A comprehensive experimental approach is established to regulate the quality of air about a selected range of different air pollutants being investigated in the indoor atmosphere of the church building. Relative humidity, temperature, carbon dioxide, particulate matter and radon were considered as the factors of air quality extents. For establishing the association among the selected parameters, the data were mathematically analyzed. The correlation coefficient confirmed a strong relationship between the indoor CO2 level and the number of public. A negative relationship between the indoor CO2 extent and indoor temperature confirmed that due to the increase in temperature the concentration of CO2 decreased as well. A solid adverse connection among indoor relative humidity and indoor air temperature showed that due to the increase in air temperature, the level of the relative humidity decreased. Some recommendations were proposed for the treatment of air quality in church buildings for human well-being.

Opis:
Current standard odor measurement methods are lab-based and require substantial investment in hardware, sample collection, training, and maintenance. Odor samples must be collected in the field using bags and brought to the lab to test. This can be a time-consuming process, with the possibility of the sample loss. The actual odor measurements are based on dilution olfactometry, embodied in the AC’SCENT® International Olfactometer, following the ASTM E679-04 standard. In recent years a portable olfactometer, the Scentroid SM100i, has been developed for odor measurements. The portable olfactometer has many advantages over lab-based standard method, especially the lower cost-per-sample. However, very little is known about the performance and reliability of portable olfactometer where the dilutions are controlled with orifices in metallic plates. It is important to evaluate the Scentroid SM100i accuracy to determine the usefulness of using it as a comparable technology for odor measurements. The main objective of this research is to compare the performance of the lab-based ASTM E679-04 method with portable odor measurement technology. Specific objectives include: (1) determining the accuracy of the dilution ratios specified by the manufacturer of both the AC’SCENT International Olfactometer and the Scentroid SM100i; (2) comparing results between olfactometers using n-butanol, a commonly used standard gas in the olfactometry field, and (3) determining the accuracy of odor measurement using real odor samples collected from livestock farms in Iowa. The AC’SCENT olfactometer had an average percent error between the factory specifications and measured dilution ratios of 5.23% compared with 14.1% for Scentroid SM100i (using plate i-2 with dilution range most comparable to the AC’SCENT olfactometer). The use of other dilution plates resulted in average percent errors ranging from 9.68% to 25.31%. The Scentroid SM100i deviated from the manufacturer specifications for flowrates and dilution ratios, but these flowrates were generally consistent with each dilution setting. Overall, the Scentroid SM100i overestimated the odor concentrations with the mean difference of 22.9% (ranging from 0.95% to 93.34%). When the post-measurement adjustment using dilution correction was made, the mean percent average difference was 11.8%.
