ALOHA – modern tool for modeling the risks associated with the spread of volatile pollutants in extraction of hydrocarbons
(2016) Kulinič, Vitalij; Maruta, Michał
During the drilling works or exploitation of hydrocarbons working devices such as high-performance engines of drilling equipment and machines are often the main sources of gaseous and particulate pollutants emitted into the atmosphere. At the time of an emergency, eg. gas leakage or eruption in a short time in the atmosphere can get high concentrations of gases such as methane and hydrogen sulphide. The Ordinance of the Minister of the environment dated 29 January 2013 determines the basic criterion for risk of H2S assessment in mining companies extracting oil or natural gas, where is possibility – during the eruption of open holes or wells-flow on the surface of the liquid containing hydrogen sulphide, posing a hazard to workers, the mining plant traffic and people staying close to driving traffic mining plant. The paper presents the modelling of the spread gases in the atmosphere during the "normal" operation on drilling rigs and the gas leakage from the damaged pipeline. Was also made an attempt to mark safe points of the evacuation out in the moment of the emergency incident.

Wydział Geologii, Geofizyki i Ochrony Środowiska
Powiązanie monitoringu środowiska i dziedzin informatycznych pozwala na sprawne zarządzanie zebranymi danymi. Państwowy monitoring środowiska odpowiada za pozyskiwanie danych środowiskowych, które wykorzystywane są w podejmowaniu decyzji mających na celu ograniczenie negatywnych skutków w środowisku. Programy pomiarowo-badawcze realizowane są w ramach siedmiu podsystemów badających powietrze, wodę, glebę i ziemię, przyrodę, hałas, pole elektromagnetyczne czy promieniowanie jonizujące. Wolnodostępne oprogramowanie takie jak GeoKettle i Talend Open Studio służy przede wszystkim do przeprowadzenia procesu ETL umożliwiającego ekstrakcję, transformację oraz załadowanie danych do hurtowni danych. Programy te posiadają wiele komponentów i funkcji pozwalających na wykorzystanie ich do przeprowadzenia analiz na danych środowiskowych m.in. takich jak: minima, maksima, średnie, posortowanie danych czy wskazanie dni, w których został przekroczony poziom dopuszczalny dla danych dotyczących zanieczyszczenia powietrza. Zdobyte informacje mogą stać się użyteczne dla procesu decyzyjnego, pozwalającego ocenić i podjąć kroki w celu poprawy stanu środowiska.

Extracting land surface albedo from Landsat 9 data in GEE platform to support climate change analysis
(Wydawnictwa AGH, 2023) Barletta, Carlo; Capolupo, Alessandra; Tarantino, Eufemia
Land surface albedo is a relevant variable in many climatic, environmental, and hydrological studies, its monitoring allows researchers to identify changes on the Earth’s surface. The open satellite data that is provided by the USGS/NASA Landsat mission is quite suitable for estimating this parameter through the remote sensing technique. The purpose of this paper is to evaluate the potentialities of the new Landsat 9 data for retrieving Earth’s albedo by applying da Silva et al.’s algorithm (developed in 2016 for the Landsat 8 data) using the Google Earth Engine cloud platform and R software. Two urban areas in Southern Italy with similar geomorphologic and climatic characteristics were chosen as study sites. After obtaining thematic maps of the albedos here, a statistical analysis and comparison among the Landsat 8 and Landsat 9 results was performed considering the entire study areas and each land use/land cover class that is provided by the Copernicus Urban Atlas 2018. This approach was also applied to the data after being filtered through Tukey’s test (used to detect and remove outliers). The analysis showed a very good correlation between the Landsat 8 and Landsat 9 estimations (ρ > 0.94 for both sites), with some exceptions that were related to some mis-corresponding values. Furthermore, the Landsat 8 and Landsat 9 outliers were generally overlapping. In conclusion, da Silva et al.’s approach appears to also be reasonably applicable to the Landsat 9 data despite some radiometric differences.

Statistical Analysis of Soil Contamination in Vicinity of Coal-Processing Plant: Implications for Ecosystem Stability
(Wydawnictwa AGH, 2025) Kochmar, Iryna; Karabyn, Vasyl
The extensive generation of waste and intensified geological processes that result from hard coal mining and active operations within mining regions have led to increases in the pollution levels of ecosystems. Most coal-mining wastes contain significant amounts of heavy metals and are, therefore, particularly hazardous to the environment. The soils around waste heaps can be contaminated with various pollutants. This article presents the results of a study of soils that were sampled in the impact zone of the waste heap of the Chervonohradska CPP of the Chervonohrad Mining District. Using statistical methods (including variogram modeling and spatial interpolation), we analyzed the spatial distributions of heavy metals in the affected soil zones. This approach allowed for an enhanced understanding of contamination-dispersion patterns and potential risk areas. The authors collected soil samples from the depth of the biotically active humus-accumulative horizon from the lower tier of the slope of the waste heap at distances of 20 m, 40 m, and 100 m from the spoil tip. We measured the contents of the studied elements in the soil using X-ray fluorescence analysis and assessed the quality of the soil by phytotesting using the Triticum aestivum L. and Lepidium sativum L. test species. It was found that the average concentrations of certain heavy metals in multiple samples exceeded the background values for the region and affected the inhibition of the development and growth of the test objects.

The assessment of the eutrophication degree in selected surface waters of the Poprad Catchment
(2012) Michałowski, Maciej
The goal of this paper is to assess the degree of eutrophication in selected surface waters of the Poprad Catchment, caused by the discharge of agricultural pollution in the Nowy Sącz District. This pollution comes mainly from fertilizers, pesticides, and animal production, providing an excessive load of nitrogen and phosphorus. 64 samples of 16 control points were analysed by the water analysis test JBL Testlab. Conclusions are based on the statistical analyses of the results.

Екологічна безпека грунтів та проект моніторингу на території Дністровського протипаводкового полігону” в межах планшету: «Галич Правобережний»

Wydział Geologii, Geofizyki i Ochrony Środowiska
Магістерська робота: 144 сторінок, 22 рисунків, 6 таблиць, 36 посилань на джерела. Об′єктом магістерської роботи є планшет Галич Правобережний в межах Дністровського протипаводкового полігону (Галицький район). Метою магістерської роботи є дослідження території планшету Галич Правобережний, збір та аналіз даних забруднення грунтів, побудова карти екологічної ситуації в межах даного планшету й розробка проекту моніторингу грунтів. Моніторинг земель - система спостережень за станом земельного фонду для своєчасного виявлення змін, їх оцінки, попередження та усунення наслідків негативних процесів. Забруднення ґрунту є результатом господарської діяльності у минулому і зараз. Найчастіше ґрунт забруднюється сполуками металів та органічними речовинами, оливами, дьогтем, пестицидами, вибуховими й токсичними речовинами, радіоактивними, біологічно активними горючими матеріалами, азбестом та іншими шкідливими продуктами. Джерелом цих сполук найчастіше є промислові або побутові відходи, захороненні у визначених місцях, або ж несанкціонованих звалищах.

The object of the master's thesis is a tablet „Kozari -1” within the Dniester engineering and environmental training, research and production flood-control polygon, which is situated on the territory of Rogatinski district of Ivano -Frankivsk region and Zhidachivski district of Lviv region . The purpose of the master's thesis is to study, develop and implement recommendations to reduce environmental risks of flooding on the valley of the Dniester within the tablet „Kozari -1” to protect the population from catastrophic floods. To assess the environmental risk of flooding the data for environmental monitoring area was analyzed, the network of which include the observation points. Based on the data and computer geomorphological maps, maps of landscape structure and quaternary sediments the network of sites for sampling was designed in order to determine the state of the environment. Research is needed to control the state of the environment, the end result of which is the preservation of natural resources, favorable living conditions for the population.
