    Opis:
    Air pollution (especially near industrial enterprises that are located mainly in densely populated regions) is one of the most significant problems of modern ecology. The purpose of this research is to study nitrogen dioxide air pollution over Ukraine, which has a negative impact on human health. As part of the research over the territory of Ukraine, the real planar distribution of nitrogen dioxide (NO2) as well as its local emissions (which make the main contribution to this distribution) were revealed using the materials of the remote sensing of the Earth from the AURA satellite. The results were calculated for the multi-year period of 2005 through 2021 and separately for 2022, which characterized the full-scale war in Ukraine and which made it possible to identify priority polluters; namely, industrial enterprises (thermal power plants, heavy metallurgy enterprises, etc.). For 17 years, the average value of NO2 was 160.78 · 102 molecules/mm2; in 2022, its concentration decreased to 126.93·109 molecules/mm2. The war manifested itself due to the shutdown of industrial enterprises, which were (and remain) priority polluters in Ukraine (particularly in large cities).

    Opis:
    Tropospheric nitrogen dioxide (NO2) is a trace gas with important impact on atmospheric chemistry, human health and a key pollutant in particular cities, measured from space since the mid-1990s by the GOME, SCIAMACHY, OMI, and GOME-2 instruments. This study present ten years (monthly and yearly averaged) dataset from Ozone Monitoring Instrument (OMI) used to investigate tropospheric NO2 characteristics and variations over Iraq during 2005–2014. Annual NO2 shows an elevation from the northern to the southern and highest values was at central parts of Iraq. Monthly distributions revels higher values NO2 in winter and summer than spring and autumn seasons, and rising NO2 throughout study period over industrial and crowded urban zones. The trend analysis over Baghdad shows a linear growth rate 9.8% per year with an annual average (5.6·1015 molecules per 1 cm2). The air mass trajectory analysis as hotspot regions shows seasonal fluctuations between winter and summer seasons depend on weather conditions and topography. The increased NO2 values in winter are due to anthropogenic emissions and subsequent plumes from Europe. In addition, in summer because of hot weather and large paddy fields emissions. The lowest NO2 value was at monsoon period mostly linked to the rains. The OMI data and satellite information are able to observe the troposphere NO2 elevation at different regions.

    Opis:
    This paper presents the dependence of air pollution with sulphur dioxide and nitrogen dioxide on wind direction in Szczecin, Łeba, Elbląg and Zielona Góra in the period 19931999. It has been shown that the most disadvantageous air quality conditions in the cities listed above are on the days with air inflow from south-east, and the most advantageous on the days with advection from north-west. This dependence is particularly evident in the case of pollution with sulphur dioxide, especially in the cold half-year.

    Opis:
    Objectives: The objective of this study was to investigate variants of case-crossover design for assessing correlations between counts of health events over time and exposure to ambient air pollution. For illustrative purposes, daily emergency department (ED) visits for depression among females were considered. Materials and Method: Ambient nitrogen dioxide (NO₂) was used as a principal ambient air pollutant. In addition, sulphur dioxide (SO₂) and carbon monoxide (CO) were considered. Different configurations of the control periods (every 1, 2, …, 10 days) and different forms (linear, natural splines) of meteorological factors in the applied conditional logistic regression models were used. The sequence of overlapping age intervals was defined ([0, 19], [1, 20], and so on) and each age group was analyzed separately. The results for the defined age sequences allow identifying age ranges in which the effects are strongest. Results: Consequently, for example, different age ranges for patients for which ED visits for depression were correlated with NO₂ and SO₂ were identified. This age-interval difference explains the very often observed phenomenon whereby two air pollutants used in one model may not show correlations with health outcomes. In this situation they affect separate age groups. The results also show dependency on number-defined control periods for the applied case-crossover technique. The opposite statistical conclusions may be generated by using different control schemas. Conclusions: The results support the hypothesis that ED visits for depressive disorder may be correlated with exposure to ambient air pollution.

    Opis:
    Introduction. Air pollution is one of the most important issues of our times. Air quality assessment is based on the measurement of the concentration of substances formed during the combustion process and micro-particles suspended in the air in the form of an aerosol. Microscopic atmospheric particulate matters (PM) 2.5 and 10 are mixtures of organic and inorganic pollutants smaller than 2.5 and 10 μm, respectively. They are the main cause of negative phenomena in the earth’s atmosphere of Earth and human health, especially on the respiratory and cardiovascular systems. Particulates have the ability to cause permanent mutations of tissue, leading to neoplasms and even premature deaths. Nitrogen dioxide (NO2) is one of the main pollutants which arises mainly during the burning of fossil fuels. Based on numerous scientific researches, it has been proved that long-term exposure to NO2 could increase morbidity of cancer due to inflammatory processes increasing abnormal mutations. Materials and method. Data available in the Polish National Cancer Registry, Chief Inspectorate for Environmental Protection and Map of Health Needs in the Field of Oncology for Poland, WHO Air Quality Guidelines 2005 were analyzed. Air pollution was also evaluated: PM2.5, PM10, NO2, and compared with lung cancer morbidity. Results and conclusions. Based on the available data and literature, it can be concluded that in 2009–2017, on average, each Pole smoked ten cigarettes a day +/- 2. Therefore, it can be estimated that after 60 years everyone had 30 package-years of smoking, leading to a high risk of lung cancer and other smoking related diseases. Additionally air quality in Poland is not satisfactory, exceeding the standards presented in the WHO Guidelines 2005. It can be assumed that this may translate into an additional, independent continuous increase in morbidity and mortality dependent on smoking.

    Opis:
    Correlations between concentrations of selected air pollutants were analyzed in different areas in central Poland from 2012-2016. Three neighboring voivodeships (Lower Silesian, Lodz, and Masovian), were selected for which specific measurement locations were designated in urban and rural areas. The characteristics of the location of monitoring stations allowed to distinguish the following types of measurement stations: “urbantransport”, “urban-background", "suburban-background", "town-background", and "rural-background". Therefore, using the Pearson's linear correlation coefficient, it was possible to analyze the interrelations between the occurrence of air pollution in various types of areas. It was found that the coefficient changed along with the type of area. Moreover, it turned out that the coefficient decreased in each voivodeship along with a decrease in the population density of the analyzed areas. In addition, concentrations of various air pollutants in given areas were compared. Also, it was observed that the strongest correlations occur between the results of calculations from measurement stations located in the same province.

    Opis:
    The influence of air pollutants on visibility in Warsaw Agglomeration has been investigated. Following pollutants were considered: PM10, SO2, NO2 and O3, while meteorological parameters included: air temperatures (mean, minimum, maximum), solar radiation, relative air humidity, rainfall rates and wind speed. Initial analyses were performed with the use of principal component analysis (PCA). In next stages, the logistic regression (LR), the analysis of variance (ANOVA), one-way classification and a model path of generalized regression models (GRM) were applied. PCA analysis showed that in the cold season the visibility index depends on PM10, SO2, NO2 and the temperatures: T, Tmin, and Tmax. In the warm season, the index of visibility is mostly shaped by four elements: O3, T, Tmax and solar radiation. Logistic regression model indicated that in the warm season only two variables are significantly related to visibility: PM10 and relative humidity of air. Regularities in the cold season shown by the LR correspond with the conclusions from the PCA. Among meteorological conditions, the most important is air temperature, but only Tmax preserves the same direction of influence as the one pointed by the PCA model.
