The aim of this study was to determine, by use PCA analysis, the impact of meteorological elements on the PM10 concentration on the example of the mountain valley. Daily values of selected meteorological elements, measured during a ten-year period in the spring, summer, autumn and winter, obtained from the meteorological station in Nowy Sącz, were adopted as variables explaining PM10 concentration. The level of PM10 was significantly affected by the maximum, minimum and average temperature in autumn, winter and spring. In summer the average and maximum temperature was significant. In winter, the first principle component mainly consisted of the combination of the average and maximum wind speed. The second principal component in spring, summer and autumn was the combination of the wind speed (average and maximum), but in winter humidity and atmospheric pressure seemed to be significant. The third principal component, in terms of strength of impact, was humidity in spring, the combination of humidity and minimum temperature in summer, and precipitation in autumn. In winter, the highest PM10 concentrations were observed during the non-directional, anticyclonic wedge conditions. Three principal components were distinguished in this situation: temperature (average, maximum and minimum); the combination of humidity and wind speed and precipitation.

The aim of the study was to assess the temporal variability of tropospheric ozone pollution. The research was carried out for the agricultural region of central-eastern Poland, an area covering the Lublin Voivodeship. One-hour averages of automatic measurements of tropospheric ozone concentration in 2015–2017 were used for the study. The data were obtained from three measuring stations belonging to the Chief Inspectorate of Environmental Protection in Poland. The stations were located as part of the Air Quality Monitoring System in rural communes in the north-western, central and southern parts of the Lublin Voivodeship. Statistical analysis of the data showed that the tropospheric ozone concentrations were significantly dependent on weather conditions during the years of the study. At each monitoring station, the one-hour average O3 concentrations showed a clear structure over the course of the day: they were higher in the late morning and early afternoon than in the early morning and at night. The highest O3 concentrations were observed at the Florianka measurement station, located in Roztocze National Park. This area had high forest cover and was located at the highest elevation above sea level of the three measuring stations. In the light of climate change and increasing O3 concentrations, further scientific research on atmospheric air pollution is crucial, especially in agricultural areas associated with food production.

Streszczenie. Sukcesywnie zwiększa się zakres i powszechność zastosowań wizualizacji danych środowiskowych w upowszechnianiu i popularyzacji wyników pomiarów terenowych i badań naukowych. Celem pracy jest analiza porównawcza wybranych technik i narzędzi komputerowych, które umożliwiają prezentację danych środowiskowych w formie wykresu wskaźnikowego, w oknie przeglądarki internetowej. Za dane wejściowe przyjęto wyniki pomiarów wykonanych w ramach monitoringu lokalnego jakości powietrza w Nowym Sączu (woj. małopolskie). Do wizualizacji danych wybrano wartości średnie godzinowe stężeń pyłów zawieszonych w powietrzu PM10 oraz PM2,5. Wykresy przygotowano z wykorzystaniem czterech alternatywnych narzędzi projektowych w oparciu o skalę pomiarową indeksu jakości powietrza. Podstawą analizy porównawczej były testy eksploracyjne (rozpoznawcze), które wykonywano techniką samooceny, w oparciu o scenariusz prac projektowych. W konkluzji zwrócono uwagę, że prezentacja danych środowiskowych w oknie przeglądarki internetowej za pomocą wykresów wskaźnikowych nie jest powszechnie stosowana, choć zdaniem autorów tkwi w niej duży potencjał, w szczególności informacyjny.

In excessive concentrations, the tropospheric ozone (the so-called trioxygen O 3) constitutes a serious threat to the ecosystems of our planet. It is a threat to the health and life of people. In plants, it contributes to disruption of the most important biochemical processes. The purpose of this study was to assess atmospheric air pollution with tropospheric ozone in selected rural villages of the Lubelskie region in the years 2015-2017. Assessment of air quality in the Lubelskie region in terms of the content of tropospheric ozone, which is significant for the protection of plants and human health, was carried out in accordance with the Regulation of the Minister of Environment of 24 August 2012 on the levels of certain substances in the air, as well as more restrictive guidelines of the World Health Organization. The research used the hourly values of automatic measurements of the tropospheric ozone immission in the years 2015-2017. The data originated from three measurement stations, which function as part of the Air Quality Monitoring System, in three rural communes located in the northwestern , central and southern part of the Lubelskie region. As a result of implemented research, no tropospheric ozone concentrations exceeding the threshold values, at which the public should be informed about the risk of exceeding the alarm level, were noted. The highest mean tropospheric ozone immission was recorded during the calendar summer and calendar spring, while the lowest was recorded during the calendar winter and autumn. In terms of human health protection, the largest exceedances of the maximum mean 8-hour value of tropospheric ozone were recorded during the calendar summer at Florianka station, which was located at the highest position (270 m above sea level) in relation to other measurement stations covered by this study. In terms of plant protection, the mean tropospheric ozone concentration, expressed with the use of AOT40, did not exceed the applicable target level (18 000 μg•m-3 •h) at any of the measurement stations. The highest mean value of AOT40 was recorded at the Florianka meteorological station (14 653.9 μg•m-3 •h), while the lowest was recorded at the Jarczew station (7 486.2 μg•m-3 •h).
