Permanent grasses such as Miscanthus are identified as potentially suitable sources of raw materials for the output of second-generation biofuels. The experiments focused on the production ability of the perennial energy grass Miscanthus were performed in the region of SW Slovakia. It was confirmed that the studied genotypes (Miscanthus sinensis Tatai and Miscanthus × giganteus) exceeded the costefficient level of biomass production. The above-ground biomass of the studied genotypes was ensiled and afterwards fed to the experimental fermenters to evaluate the biogas production. The experiments with individual silage mixtures lasted 600 hours. The total amount of biogas produced from M. × giganteus and M. sinensis Tatai silage mixture was 273 dm 3 and 328 dm 3 , respectively. The average share of methane in the biogas of both studied samples of silage mixtures was 51%. On the basis of the 10-year average yields of the studied Miscanthus genotypes achieved in our conditions, it is possible to produce 8 181 m 3 /ha (M. × giganteus) and 11 248 m 3 /ha (M. sinensis Tatai) of biogas from the silage mixtures. The achieved production represents sufficient and stable amount of biogas and its use can be economically efficient and sustainable in the long run in SW Slovakia.

Roussel and Imleria badia (Fr.) Vizzini from three areas in Slovakia (Prašice, Bobrov and Dobroč). Qualitative and quantitative determination of the observed elements was performed by ICP-OES and/or CV-AAS. All results were statistically evaluated at both descriptive and differential analysis level. Due to the fact that picking and subsequent consumption of edible wild mushrooms is popular in Slovakia, the data obtained were evaluated and compared to tolerable weekly intakes defined by WHO. Based on the content of the monitored elements, PTWI values were not exceeded in any of the species from the studied sites. In some cases, however, specific content values, especially Al, but also Cd and Hg were exceeded compared to the average concentrations of elements in mushrooms from uncontaminated areas. I...

In 2011, it had colonized the area of 100 654 m 2 in abandonment vineyards and permanent grasslands in the district of Veľký Krtíš (South Slovakia). We found the infiltration of these plants into the stands of Triticum aestivum and Helianthus annuus. No management measures were taken. In contrast, the second studied invasive plant Fallopia japonica had occupied area lower by 93 % (7276 m 2 ), but spread across higher number of sites (19) on the banks of the brooks and along the roads. Regulated populations accounted for only 11% of the total area occupied by F. japonica. Low correlation dependence was found between the size of the area and population density of A. syriaca (r = 0.50) and F. japonica (r = 0.56).

However, they are considered a risk commodity due to their extremely high capacity for bioaccumulation of potential risk elements and pollutants from the environment. Four bolete mushrooms from the genus Leccinum were collected from 16 forested areas of Slovakia from June to October 2019. The total mercury content in soil and fruiting body parts was determined by an AMA-254 Advanced Mercury Analyzer. Soil pollution by total mercury was evaluated by contamination factor (Cfi). Bioaccumulation factor (BCF), translocation factor (Qc/s), percentage of provisional tolerable weekly intake (%PTWI), and target hazard quotient (THQ) were used to describe and compare uptake and transition abilities of mushrooms, and the health risk arising from consumption of the mushrooms. Total mercury content varied between 0.05 to 0.61 mg kg−1 DW in the soil/substrate samples, and between 0.16 and 5.82 (caps), and 0.20 and 3.50 m...

These three elements were determined in 94 Macrolepiota procera (Scop.) Singer samples (separately for caps and stems) and their corresponding soils/substrates collected from 8 different localities in Slovakia. Arsenic and cadmium were analyzed by Optical Emission Spectrometry with Inductively Coupled Plasma (OES-ICP), and mercury by Advanced Mercury Analyzer (AMA-254). In the soil/substrate As content varied from ND (not detected) to 11.9, Cd from 0.66 to 22.9 and Hg from 0.02 to 0.28 mg kg-1 DW (dry weight), respectively. In fruiting body stems arsenic content varied from ND to 4.77, cadmium from ND to 5.96 and mercury from 0.03 to 2.83 mg kg-1 DW. In the caps, As content varied from ND to 13.0, Cd from ND to 19.8 and Hg from 0.04 to 4.00 mg kg-1 DW. After comparing obtained results with the EU limits, for As in mushrooms 6.6% (cap) of analyzed samples exceeded the limit value, while for Cd, 4.7% (cap),...

The paper discusses the current state of biomass energy use in the EU and Slovakia. Residual biomass was found as a key feedstock for the European bioeconomy. Slovakia is one of the most forested and rural countries in the EU. Therefore, biomass energy has the highest technical potential from all renewables in Slovakia. The main objective of the paper was to evaluate the phytomass production of the selected crops and their energy potential in individual self-governing regions of Slovakia. It is focused on the production of usable post-harvest residues theoretically used for energy purposes from the following studied main crops: wheat, rye, oats, barley, maize, potatoes, oilseed rape and sugar beet. The results show the estimated production of usable post-harvest residues of the selected crops and their energy potential in individual self-governing regions in Slovakia in 2019. The total production of usable...

In the first part, we monitored the bioconcentration potential of individual anatomical parts of a particular fruiting body and evaluated the obtained data by the spline interpolation method. In the second part, we focused on assessing the mercury content in 378 samples of N. luridiformis and associated samples of substrates from 38 localities with different levels of Hg content in Slovakia. From the obtained data of Hg content in samples of substrate and fungi, we evaluated ecological indicators (geoaccumulation index - Igeo, contamination factor - Cf a potential ecological risk - PER), bioconcentration indicators (bioconcentration factor - BCF; cap/stipe quotient - Qc/s) and health indicators (percentage of provisional tolerable weekly intake - %PTWI a target hazard quotient - THQ). Based on the Hg distribution results, the highest Hg content was found in the tubes & pores (3.86 mg/kg DW), followed by the flesh of cap (1.82 mg/kg DW). The lowest Hg content was in the stipe (1.23 mg/kg DW). The results of the BCF values indicate that the studied species can be included in the category of mercury accumulators. The results of the ecological indices representing the state of soil pollution pointed out that two localities (Malachov and Nižná Slaná) stood apart from all monitored localities and showed a state of an extremely disturbed environment. This fact was also reflected in the values of Hg content in the fruiting bodies of the studied mushroom species. In the case of the consumption of mushrooms from these localities, it can be stated that long-term and regular consumption could have a negative non-carcinogenic effect on the health of consumers. It was confirmed by the %PTWI (Malachov: 57.8%; Nižná Slaná: 53.2%) and THQ (Malachov: 1.11 Nižná Slaná: 1.02). The locality Čačín-Jelšovec is interesting from the bioconcentration characteristics point of view, where the level of environmental pollution was the lowest (Hg content in the soil was below the background value) compared to other localities, however, the THQ value was the highest (1.29).

There were four varieties of willow (Salix spp.) and four varieties of poplar (Populus spp.) included in the research. The studied willow varieties were Inger, Express, Klara and Dimitrios, and the poplar varieties were Monviso, Pegaso, AF-02 and Sirio. The research took place in the field trial at a farm holding belonging to Slovak University of Agriculture in Koliňany. The site is located at an altitude of 180 m above sea level and belongs to temperate, very dry and lowland climatic region. The production parameters observed on all the varieties of willows and poplars were the number of shoots per individual, length and diameter of shoots, number of shoots in various categories of shoot length and diameter, above ground biomass yield at harvest moisture content and in dry matter and annual production of above ground biomass in dry matter. The r...

The purpose of this paper is to point out the possibilities of using the fast-growing giant reed Arundo donax L. that is not used as fodder and can be grown on low-quality agricultural land. The experimental stand of A. donax L. used in the study provided a yield of 60.8 t ha-1 of fresh biomass in the third year of cultivation. Part of the biomass produced was ensiled as maize and later the silage was co-fermented with cattle excrements and pig slurry. The resulting biogas can be used as fuel for internal combustion engines. The average content of CH 4 and CO 2 is 52% and 44%, respectively. These values are very similar to the composition of maize silage biogas. The average hydrogen sulphide content in the biogas from A. donax L. was 730 ppm. The disadvantage is that the biogas production is 46% lower compared to maize silage.

Total content of mercury in soil and mushroom samples was determined by an AMA-254 analyzer. Soil pollution by mercury was evaluated by contamination factor (Cf), pollution load index (PLI), and geoaccumulation index (Igeo). Bioaccumulation factor (BAF), translocation factor (Qc/s), provisional tolerably weekly intake (%PTWI), estimated daily intake (EDI), and target hazard quotient (THQ) were used to describe and compare uptake and transition abilities of mushrooms, and the health risk arising from mushroom consumption. Mercury content in soil significantly influences the content of mercury in mushroom fruiting body parts. Caps and stipes of Boletus subtomentosus were found to be the best mercury accumulator. According to the EDI, consum...

The varieties included in the research were Jorunn, Jorr, Bjőrn, Klara, Lisa, Terra Nova, Loden and Dimitrios. During the research period (2009-2011), we observed climatic conditions of the research site, soil moisture, groundwater level and occurrence of diseases and pests. The production parameters determined in the study include the rooting of 0.20 m long cuttings of one-year old shoots, number, length, diameter and weight of shoots produced on rooted cuttings and weight of individual plants. There were very different climate conditions observed during the research period on the site. Years 2009 and 2011 were characterized by low amount of precipitation compared to the long-term average. On the contrary, the year 2010 was extremely rich in atmospheric precipitation, ...

However, from an ecotoxicological point of view, they are a risk commodity because of their extremely high bioaccumulative capacity to accumulate the risk elements and contaminants from the environment. In the present study, we examined mercury (Hg) contamination in 230 fruiting bodies of Macrolepiota procera (Scop.) Singer and 230 soil/substrate samples, which were collected in foraging seasons 2015–2019 from 22 different locations in Slovakia. Total mercury content was determined by cold-vapor AAS analyzer AMA 254. The level of contamination and environmental risks were assessed by contamination factor (Cf), index of geoaccumulation (Igeo), and potential environmental risk index (PER). Bioaccumulation factor (BAF) was calculated for individual anatomical parts of M. procera. Mercury content in the soil/substrate sampl...

Soil and ambient air are influenced by hazardous substances, which leak from old mining bodies due to insufficient or completely missing reclamation. The total content of the risk elements (As, Cd, Co, Cu, Fe, Hg, Mn, Ni, Sb, Se, Pb, Zn) was determined in soil, moss, and lichen samples and in the bodies of Leccinum pseudoscabrum. Biological (soil enzymes—urease, acid phosphatase, alkaline phosphatase, fluorescein diacetate (FDA), ß-glucosidase) and chemical properties (pH) were determined in soil samples. Contamination factor (Cf), degree of contamination (Cd), pollution load index (PLI), and enrichment factor (EF) were used for soil and relative accumulation factor (RAF) for air quality evaluation. Contamination factor values show serious pollution by Cd, Fe, Hg, and Mn. Pollu...
