The aim of the study was to compare accumulation capacity of selected biogenic and toxic metals (As, Cd, Cu, Pb, Sb, and Zn) in the leaves of 3 tree species (Alnus glutinosa, Salix sp., and Sambucus nigra) from 5 locations in the Malé Karpaty Mountains in the Slovak Republic near Trniansky, Stoličný, and Gidra streams. These observed locations (with accentuation to upper flows of mentioned streams)...
The toxicity of arsenic (As) in different polluted areas and its effects on human and animal health is a big concern all over the world. Although a wetland ecosystem is a “green filter,” this specific function would be impaired by high As content in wetland sediments. The distribution of As in wetland sediments and its linkages to environmental factors have not been fully explored. In this study,...
The benefits of bioretention systems are very important to the environment. Because of low knowledge in the field at a national level (in Romania), they are not promoted or implemented. The aim of this research was to develop and promote bioretention systems in Romania, with particular reference to one of the biggest urban developments: Cluj-Napoca. We used the RECARGA to determine effective models...
The aim of our study was to evaluate the influence of reclamation activities in a tailing pond, consisting in the application of mineral (rock aggregate) and organic substances (crop willow chips, swarf) and reclamation plants such as various species of grass and their mixtures with water-absorbing geocomposites, on the selected physical and biological parameters of the sediment. The experiment was...
Ricinus communis L. was found to vegetate mine tailings with high concentrations of Al (4,456 mg kg⁻¹), As (3,473 mg kg⁻¹), Cd (120 mg kg⁻¹), Cr (14 mg kg⁻¹), Cu (1,147 mg kg⁻¹), and Pb (910 mg kg⁻¹). We investigated how this plant responded to increased heavy metal concentrations by mixing mine tailing at 0%, 50%, 70%, and 100% with soil at 100%, 50%, 30%, and 0%, while metal concentrations in the...
2,4-Dichlorophenol (2,4-DCP) acclimated activated sludge culture was immobilized in polyurethane foam and supplemented to a packed upflow column bioreactor (PUCB) to treat 2,4-DCP containing wastewater. The impact of sludge age and 2,4-DCP concentration on biodegradation performance were studied. Results show that sludge age affected biodegradation in the PUCB. The residence time was adjusted by feeding...
Accurate short-term power load forecasting is becoming more and more important for the stable operation and improved economic benefits of electric power systems. However, when affected by various factors the power load shows non-linear and non-stationary characteristics. In order to forecast power load precisely, we propose an extreme learning machine (ELM) combined with variational mode decomposition...
The objective of this work was to present the tourism potential (PT) and tourism attractiveness (AT) of municipalities located in the impact areas of Polish national parks. Moreover, the classification of the municipalities based on the so-called tourism utilization rate has been elaborated. According to the analysis, the percentage of the municipalities of each type in terms of TP and TA is very...
This paper analyzes the correlation between soil moisture data and different spectral data transformation, and it reveals that the correlation coefficient of soil moisture is highest near 584 nm, 711 nm, 1,055 nm, 1,420 nm, 1,635 nm, 2,176 nm, and 2,257 nm. The highest correlation coefficient can be up to 0.83206. Multiple regression analysis can be done to understand the correlation between the two,...
The aim of this paper is to identify the main factors that determine territorial differences between two large neighbouring provinces (Granada and Almería) that each occupy both sides of the Sierra Nevada mountain range in southern Spain. Our analysis produced a prediction model for riverside woodland cover, one of the variables that most strongly characterizes the differences between the two provinces...
