abstract = {Progressive industrialisation and urbanisation in recent decades have dramatically affected the soil cover and led to significant changes in its properties, which inevitably affect the functioning of other components of the forest ecosystems. The total content of Pb, Cd, Zn, Fe, Cr, Cu, Ni, As, and Hg was studied in twenty-five plots at different heights in the topsoil (organic and humus horizons) formed from the Carpathian flysch in the area of the Silesian Beskids (Western Carpathians). The aim of this article is to analyse the spatial distribution of potentially toxic elements in the mountain forest topsoil in different types of plant communities and to determine the relationship between altitude and potentially toxic elements contamination. The soils studied are acidic or very acidic, with an average range of 3.8 (H2O) and 2.9 (KCl). Concentrations of the metals Cd, Zn, Fe, Cr, Cu, Ni, and Hg on the plots that were analysed are within the range of permissible standards for forest ecosystems in Poland, while Pb and As exceed the permissible standards for this type of ecosystem. Spearman’s rank correlation coefficient showed a high correlation between Fe–Cr (r(32) = 0.879; Pb-Hg r(32) = 0.772; Ni–Cr r(32) = 0.738; Zn-Cd r(32) = 0.734; and Cu-Hg r(32) = 0.743; and a moderate statistically significant positive correlation between Cu-Pb r(32) = 0.667 and As-Pb r(32) = 0.557. No correlation was found between altitude and the occurrence of potentially toxic elements. The geo-accumulation index (Igeo) index; on the other hand; indicates that Pb; As; and Cd have the highest impact on soil contamination in all study plots: it classifies soils from moderately to strongly polluted. The enrichment factor (EF) obtained for As and Hg indicates significant-to-very high enrichment in all areas studied. The potential ecological risk index (PLI) calculated for the sites indicates the existence of pollution in all areas examined. The highest risk categories (considerable to very high) are associated with cadmium and mercury. © 2024; The Author(s).},

abstract = {Forest ecosystems and urban parks are an integral part of the natural environment and the natural system of a city, where they form a mosaic of habitats resulting from the variation in soil cover due to human activities. The study was conducted in urban forests in five urban parks in Upper Silesia (southern Poland) and investigated the chemical properties and content of potentially toxic metals (PTMs) in the topsoil, which had an average thickness of 15 cm for all samples. The soil reaction ranged from acidic (pH = 4.7–5.1; in KCl) to slightly acidic (pH = 5.6; to neutral—6.6–7.2) at most sites. The organic carbon (OC) content was relatively high at all sites, ranging from 1.19 to 14.3%, with the highest total nitrogen (Nt) content being 0.481%. The average total phosphorus (Pt) content in the parks ranged from 310 mg kg−1 to 684 mg kg−1, while the highest values were 1840 mg kg−1. The total Cr, Cu, Co and Ni content was within acceptable limits, while the Zn, Pb, Cd, As, Sr and Ba exceeded acceptable standards. In terms of content, Zn dominated the PTMs at each site (Zn > Pb > Ba > Sr > Cu > Cr > As > Ni > Cd > Co), while Ba and Pb alternated in taking second place (Zn > Ba > Pb > Sr > Cu > Cr > Ni > As > Co > Cd). Environmental indicators, such as the geoaccumulation index (Igeo), enrichment factor (EF) and potential ecological risk index (RI), showed that the analyzed soils are highly contaminated with PTMs. Among the sources of pollution in the urban forest are low emissions from coal combustion, industrial activities, water runoff from streets and proximity to transportation routes. Identification of PTM levels in urban parks will provide valuable information on the behavior of these metals, which is important in sustainable development and can help evaluate the local spatial development plans of urbanized areas. © 2024 by the authors.},

abstract = {The air pollution of our planet is rising, and the contribution of road transport to global pollution has a serious impact on this phenomenon. Previous papers have analysed and recommended measures to reduce road transport's negative environmental impact and carbon footprint. However, some restrictions are impossible (or very costly) to meet, even in developed countries. Unfortunately, presenting the impact of transport on air pollution levels as a whole can only give a general picture. This paper provides a more detailed analysis and attempts to assess the impact of one of the most important elements shaping modern transport, that is, vehicle engine types. Thus, the main objective of the study is to analyse and evaluate the different types of engines in vehicles from the point of view of technical, environmental, and economic aspects in European countries and to verify whether Europe is ready to implement the European Green Deal. The results indicate significant technological developments must occur in electric vehicles to become environmentally better than combustion engine-based cars. Additionally, in the case of some developing countries, owning a means of transport is still perceived as a symbol of a certain status, which is why it is still an important material asset. Thus, in rich countries, material status and environmental awareness (e.g. choice of public transport) will help to achieve climate neutrality, while poorer countries (even developed ones) may have severe problems in meeting EU requirements. Overall, while answering some questions, this article also poses new ones. Decision-makers often face challenging aspects. This article is intended to give them a basic knowledge to pursue an environmental policy that is viable and feasible for all countries. © 2024 Kamil Maciuk et al., published by Sciendo.},

abstract = {Decisions to build or remove dams and other large engineered hydraulic infrastructures are always entangled in social and environmental impacts, which are often evaluated formally through bureaucratic processes. In Europe dam removals are relatively infrequent, even though extensive hydraulic infrastructure has degraded biodiversity and water quality. The Wilkówka dam in southern Poland was required to be removed rapidly, primarily due to engineering failures during its construction. Using survey methods, we examine the local community's perceptions of the net environmental and social impacts of the Wilkówka dam removal. In surveying the opinions of households, 62% of respondents expressed that decisions about the removal were taken without sufficient community consultation, and 92% felt that the dam had been removed despite their opposition. Although the dam had been built recently and had failed to operate at design capacity, respondents reported strong attachments to the services they perceived it to provide, including water supply, flood regulation and cultural significance. In spite of the possibility of an environmental disaster and long-term environmental degradation, most surveyed households would have preferred it to have been renovated or reconstructed. In short, the removal of the Wilkówka dam was perceived by local households but also by local officials as bringing about a net loss in socially relevant ecosystem services, despite the urgent need for removal perceived by regional and national authorities. The local community's rapid attachment to the dam despite its potential negative impacts on biodiversity and the local environment were primarily attributable to the high expectations as to the hydrological services that the dam was to provide (water supply; flood regulation and its larger symbolic value as an infrastructural investment in the community). This work provides an empirical demonstration of the importance of understanding the social, ecological and technological context within decision-making processes regarding dam removals, and its implications may improve the planning and implementation of future dam removal projects. © 2024 The Authors.

abstract = {Anthropogenic ecological ecosystems create favourable conditions for the growth of the nitrophilous medicinal species Chelidonium majus in six urban parks in Southern Poland. This study focuses on the concentrations of trace elements in the soils, leaves, stems, and rhizomes of greater celandine. The soil samples were taken only in the humus horizon (A), which averaged approximately 15 cm in thickness under the clumps of Ch. majus. Regarding the reaction, the soil samples tested can be described as slightly acidic (5.6–6.8 in KCl) to alkaline (7.1–7.4 in H2O). Organic carbon content at all sites is high, ranging from 3.2% to 13.6%, while the highest total nitrogen (Nt) content is 0.664%. The average total phosphorus (Pt) content in all samples is 548.8 mg/kg (and its range is 298–940 mg/kg), such values indicating its anthropogenic origin. In terms of heavy metals, Zn has the highest content in the analysed soil samples compared to the other elements, and its range is from 394.50 mg/kg to 1363.80 mg/kg in soil. In rhizomes, Zn also has the highest values (178.7–408.3 mg/kg), whereas, in stems and leaves, it varies (from 80.6 to 227.5 and from 57.8 to 297.4 mg/kg; respectively). Spearman’s rank correlation showed high correlations between the content of Pb, Zn, Cd, and As in the soil and rhizomes of Ch. majus. Despite soil contamination with Pb, Cd, and Zn, Ch. majus does not accumulate them in its tissues. However, the translocation of Hg and Cr from rhizomes to leaves was observed. The different concentrations of metals in each park result from the degree of diversity of the parent rocks on which the soil was formed. © 2023 by the authors.},

abstract = {Spatiotemporal modelling of infectious diseases such as coro¬navirus disease 2019 (COVID-19) involves using a variety of epi-demiological metrics such as regional proportion of cases and/or regional positivity rates. Although observing changes of these indices over time is critical to estimate the regional disease bur¬den, the dynamical properties of these measures, as well as cross-relationships, are usually not systematically given or explained. Here we provide a spatiotemporal framework composed of six commonly used and newly constructed epidemiological metrics and conduct a case study evaluation. We introduce a refined risk estimate that is biased neither by variation in population size nor by the spatial heterogeneity of testing. In particular, the proposed methodology would be useful for unbiased identification of time periods with elevated COVID-19 risk without sensitivity to spatial heterogeneity of neither population nor testing coverage. We offer a case study in Poland that shows improvement over the bias of currently used methods. Our results also provide insights regard¬ing regional prioritisation of testing and the consequences of potential synchronisation of epidemics between regions. The approach should apply to other infectious diseases and other geo¬graphical areas. © The Author(s), 2022 Licensee PAGEPress, Italy.},

The study makes use of the test of independence and Cramer’s V as a post-test, and the method of in-depth interviews. The results indicate that the most popular new functions of post-industrial sites are production and services.

We show the variability of these types over time, from the Type J (moderately mobile; consistent) in the 1990s to the Type H (moderately mobile; mixed) at present. A detailed analysis reveals a major difference between international and internal migrations: The former are mainly due to economic reasons and the latter to reasons related to housing. The obtained results allow us to conclude that pensioner migrations constitute an important factor in the social and economic development of local communities, especially in the day and age of society ageing and lengthening life expectancy. © 2020 John Wiley & Sons, Ltd.},

The research area comprised Polish national parks as they are characterized by barely altered nature, little human impact, and undisturbed natural phenomena. The methods involved the observational method, literature analysis and criticism, and the in-depth interview method employed in November 2019. The respondents included national park management staff. The questions were prepared in accordance with the Berlin Declaration principles of sustainable tourism development and were extended with the authors' own items. The questionnaire contained 17 questions, grouped in four parts: science and documentation; tourism; cooperation and education; environmental threats. The results indicate that in order for actions to prove efficient in a park, a conservation plan should be carefully developed. Its correctness requires monitoring the state of the environment, tourist traffic size and trends, and tourists' impact on the environment. An important condition for effective tourism management in parks is to increase the competences of the administering bodies and knowledge regarding individuals' responsibilities. Boards should be able to evaluate and modify conservation plans, spatial development plans, municipality development strategies, and projects for investments within the parks. © 2020 by the authors.},

This paper explores the question why Polish pensioners decide to migrate, as existing research has not provided satisfactory explanations. Reasons for migrations were determined on the basis of pensioners' answers to a questionnaire survey. The results show that migration decisions are taken for a number of reasons, which depend, inter alia, on the respondents' education level, age, and sex. For women as well as for men, the economic aspect plays a crucial role (e.g.; building or buying a new house). Ward's method was employed to distinguish five main migration types according to the main motivating factor; that is, family and finance, family, environmental, economic, and health. An analysis of internal as well as external migrations of Polish seniors shows that they differ considerably from migrations of seniors in other countries. Due to their unsatisfactory finances as well as deficits in knowledge of foreign languages, Polish pensioners, unlike their peers in other countries, rarely decide to settle down abroad. The Polish model of multigenerational family in which seniors assist their children in raising their grandchildren also contributes to lower emigration. © 2018 John Wiley & Sons, Ltd.},

abstract = {Owing to the world demographic situation, the phenomenon of senior tourism is dynamically developing. More and more retired people want to travel and get to know new places. Therefore, the paper aims to compare the tourist activity of retired people and that of mobile working age people. The results obtained in the performed analysis allow to conclude that the tourist activity of pensioners and of young people is not similar. On the basis of the analysis of the selected characteristics of tourist activity and the seniors' age with the use of the chi-squared test, the authors pointed at the relationships occurring among these characteristics. The comparative analysis showed that the tourist expectations of the studied groups are different. The results prove that the diversity of travel concerns many problems. © 2019 University of Presov.

abstract = {The paper presents methods of determination of analytes of the cation group (alkyl benzyl dimethyl ammonium (BDDA-C12-C16); alkyl trimethyl ammonium (TMA); hexadecyl piridinium (HP)) in surface water and bottom sediment samples. In the sample preparation phase the solid phase extraction (SPE) or accelerated solvent extraction/ultrasound assisted extraction (ASE/UAE)-SPE technique was used and in the identification phase and quantitative determination of analytes phase - ion chromatography technique (combined with a conductivity detector (CD)). The determined concentrations were in the range below the determined method detection limit (MDL) or method quantification limit (MQL) figures up to 0.142 ±0.023 mg/dm3 or 2014 ±10 μg/kg (liquid and solid samples; respectively). Comparing concentrations of individual analytes found in liquid and solid environmental samples we may notice that surfactants containing a shorter alkyl chain in their molecules were found in higher concentrations in liquid samples (hydrophobicity increasing with the chain length). © 2018 Marek Ruman et al., published by Sciendo 2018.},

abstract = {Nowadays we deal with both rapid population ageing and considerable increases in international migrations of people over 65. Consequently, the aim of this paper is to present the destinations Polish pensioners choose when moving abroad. The most popular destination country is Germany, which results from the family networks binding pensioners with this country. This fact is confirmed by the cumulative causation theory, which argues that a combination of several factors is necessary for migrations to occur. Pensioners face low incomes, and after retirement they seek opportunities to raise them. However, going abroad to work is not easy due to lack of knowledge of foreign languages. Mobility is facilitated by existing migration networks, i.e. migrants move to join their families and friends. © 2018 University of Presov. All rights reserved.},
