Abstract Microbiological and chemical analysis of air was carried out on the area of landfill of wastes other than inert or hazardous. The landfill covers 20 ha and 40 000 Mg of wastes is deposited annually. Municipal waste is not segregated at the landfill. The research was conducted in April, May and November 2012. Number of the psychrophilic and mesophilic bacteria and fungi was estimated by a culture-based method. Quantitative determination of sulfur compounds and meteorological and olfactrometric examinations were also carried out. Chemical analysis was conducted with a Photovac Voyager portable gas chromatograph. Air samples were collected at 5 points. The largest group of microbes were psychrophilic bacteria, especially in summer. The highest concentration of hydrogen sulfide and other odorants was found at leachate tank and landfill body. According to the Polish Standard for the assessment of atmospheric air pollution the air in the area of the landfill is classified as not contaminated and sporadically moderately contaminated. In spring and summer the number of microscopic fungi was increased also in control samples.

Abstract. In the frame of the European project, entitled MULTI-ASSESS, specimens of structural metals, glass, stone and concrete materials were exposed to air pollution at a station, which was installed for this purpose on a building, located in the centre of Athens. The main purpose of this project was to determine the corrosion and soiling effects of air pollution on materials. A set of the specimens was exposed in a position that was sheltered from rain and partly from wind, and another set was exposed in unsheltered positions on the roof of the above said building. In addition, other specimens were exposed at different heights on the same building, in order to investigate for the first time the corrosion and soiling effects on various materials as a function of height. For the determination of these effects, chemical analysis of the specimens was performed and basic parameters as the weight change, the layer thickness and the optical properties were calculated. Finally, the results obtained are discussed and their plausible interpretation is attempted.

The rapid development that spills over into rural areas has resulted in rural areas in the State of Johor is no exception showed deterioration of air quality as a result of development. The study area was in Kampung Paya Pulai, Segamat; Parit Raja, Batu Pahat; Kampung Sri Bahagia, Mersing and Kampung Pok and Johor Bahru. Air quality sampling for this study is for gas pollutant SO2, NO2, CO, O3 and PM10 which requires sampling for one hour. Gases such as SO2, NO2 and CO2 content gas concentration values are seen in air through air quality sampling tool YESAIR Model #6000. While sampling the Ozone O3 through the tool Detector. These two tools are portable and direct reading of values obtained after the observations made on-site sampling study area. While PM10, the air samples are collected using the tool per sample air G2142 Model E-Sampler. Recorded Data will be transferred to the computer using Terminal Utility Software (TUS) to analyzed. Air observation was carried out three times a day, in the morning, noon and night. Air quality sampling performed on two different days which are business days in Johor (Monday-Friday) and not working (Saturday & Sunday). While for pollutants PM10 is determined within the last 24 hours. Determination of air quality based on the Standards referenced/air quality environment in Malaysia, issued by the Department of Environment (DOE). The results showed pollution occurs in all rural areas in the State of Johor. Gas SO2 and NO.2 show the highest reading was in Parit Raja with each recitation of SO2 am 0.011 0.024 noon and night, 0.008 ppm, while NO.2 at reading in the morning, noon and 0.009 0.011-night 0.005 ppm. The main gas contributing to air pollution is PM10, CO, and O3 in all areas of the study. API on average less than 50 reading still categorized as ' healthy '. Only one station that recorded the value of the ' medium ' in Kampung Paya Pulai, Segamat contributed by the concentration of PM10. It is hoped that this study will serve as a guide to community and stakeholders in the development of rural areas and the need to maintain the air quality in rural areas.

This article discusses the impact of suspended particles on human health, by providing small definitions of PM2.5, including how they appear, what particles they consist of, and how they harm the respiratory and circulatory systems.  In addition, the analysis of the pollution level of the city of Almaty for the last three years from March 22, 2017, to October 6, 2020, with categorical intermediate values of suspended particles was carried out. Careful work was done with the SCV file such as data was skipped in the cells, that is, there were empty values; translation to a single data type; filling in empty cells. It also considers making a decision on the six categories provided to identify the average meeting categories. The authors identified specific categories based on digital readings of values received from sensors, where each category has its own verbal values that are understandable for each person. The indicator displays with weights as a graph for a specific Seifullin-Dulatov sensor location with categorical and without categorical division. Then for each intersection or location of the sensors is shown in a table. It is also revealed which level or category is the rarest among the others and the most common category as well.
