“…It facilitates land use decision making for the concerned authorities. However, the ratio between the LE and SA subsystems requires scientific exploration, and the evaluation results require extensive analysis for farmland protection zoning combined with the geographic information system (GIS) technique, which has been advantageous in soil conservation and evaluation applications (Vilek, Koco, Torma, Loák, & Antonkiewicz, 2019).…”

Farmland evaluation has become a major topic in farmland protection research. Due to the lack of reasonable and scientifically reliable evaluation methods for farmland protection, the farmland of quality and covering a wide area are at high risk of degradation and destruction in China due mainly to rapid industrialization and urbanization. The land evaluation and site assessment (LESA) system has been successfully applied to protect important farmland globally. To better understand and testify the flexibility and suitability of the LESA system for farmland protection in different geomorphic regions in China, we investigated the delineation of basic farmland by applying and testing the LESA system in Liaoning Province of China. In this study, the LESA system was constructed and comprehensively evaluated through the land evaluation (LE) and site assessment (SA) subsystems; soil conditions suitable for agriculture and site conditions feasible for other land uses were selected in the LE and SA subsystems, respectively. The results demonstrated that the ratios of the LE and SA subsystems were 6:4, 5:5, and 4:6 in the middle plain area (MPA), eastern mountainous area (EMA), and western hilly area (WHA), respectively. Farmlands with LE scores over 80 accounted for 80.7%, 34.7%, and 28.6% in the MPA, WHA, and EMA, respectively. Moreover, 37.2% of farmland with high SA scores (over 50) was primarily distributed in the WHA, and only 7.1% and 0.4% in the MPA and EMA, respectively. The farmland ratios with LESA scores over 60 were 74.8%, 52.2%, and 30.2% in the MPA, EMA, and WHA, respectively. In particular, the total farmland was grouped into three primary categories, which scientifically demonstrated the suitability and compatibility of the farmland features and also provided guidance for the implementation of farmland consolidation and remediation techniques.

“…The Spiš region is located between two important emission sources of environmental pollution. The first of these is Krompachy, responsible for lead, zinc, manganese, and copper production (Vilček et al 2012 ). The second is Rudnany, responsible for mercury, lead, cadmium copper, and zinc contamination (Angelovičová and Fazekašová 2014 ).…”

In this study, mercury (Hg) concentrations were detected in feathers of golden eagle (Aquila chrysaetos), a bird that typically inhabits alpine and forest areas. The mercury rates in feathers were compared in two groups of eagles: first, estimated home range (breeding, hunting, etc.) was located only in forest and lowland meadow habitats; second, the home range also included alpine habitats—rocks and meadows. Consequently, mercury concentration based on the feather typology were observed and the mercury levels in feathers were also compared among different Slovak Western Carpathian districts. It was found that there was no significant difference between groups classified by elevation level, which we attribute to the fact that eagle hunting territories are broad, so that alpine-dwelling and forest-dwelling eagles do not only reflect the pollution of the environments they typically inhabit. Non-significant differences were found also within different feather types, which means that the type of feather is not crucial for tracking mercury in eagle feathers. As the measurement of feather appears to be a simple and non-invasive method, the detection of non-significant differences in diverse types of golden eagle feathers provides useful knowledge for the future environment monitoring. The average mercury concentration measured in eagle samples was lower than the mercury concentration causing health complications among birds of prey. Our assumption that due to past mining activity in the Spiš region, the highest concentration in this region would be observed was confirmed.

Several procedures for extracting content from different waste materials types were investigated, with the aim of evaluating their environmental impact. The waste materials consisted of wastes from bauxite ore processing by means of the Bayer process (red mud, Ajka, Hungary), bauxite ore using the sintering process followed by the Bayer process (brown-red mud, Žiar nad Hronom, Banská Bystrica region, Slovakia) and sulphide ores (metal-rich post-flotation tailing, Lintich, Slovakia). The extraction procedures were carried out with the aim of isolating “mobilizable” fractions using 0.05 M ethylenediaminetetraacetic acid (EDTA) and 0.43 M acetic acid (AA) (representing environmental risk during changes in normal environmental conditions) and “maximum potentially mobilizable” fractions using 2 M HNO3 (representing the total environmental risk). The content of chosen toxic heavy metals (THMs) (Cd, Cr, Cu, Pb, Ni, Zn) and Fe, Mn as metals creating Fe/Mn oxides in the extracts and solutions after microwave digestion was determined using high-resolution continuum source flame atomic absorption spectrometry (HR CS FAAS). On the basis of the results obtained in this study, it is possible to state that different origin of waste materials is reflected in different mobility of toxic heavy metals into the surrounding environment. From the point of view of toxic heavy metals mobility, disposal site of wastes after bauxite processing are much less of a threat to the environment than disposal site of flotation sludge after processing sulphide ores. The single extraction of 0.43 M AA is more effective than the extraction of 0.05 M EDTA for the purposes of determining the content of metals in the mobilizable fraction of tailing waste materials. The mobility of the studied toxic heavy metals in the Lintich tailing decreases in the direction from the lagoon to the dam, which may indicate the fact that the dam serves to a certain extent to inhibit the mobility of metals into the surrounding ecosystem.
