This paper is focused on evaluating the quality of bottom sediments and water in the watershed of the Delňa creek, where gold, antimony and mercury were mined in the past. The results showed that the biggest source of pollution was a heap of mining material, where the limit values of Sb, As, Hg and Pb concentrations in the sediments were exceeded. Other sources of pollution in the river basin were the right-hand tributaries. A comparison of the dependencies of the concentrations of potentially toxic metals in the water and sediments shows that while the concentrations of pollutants in the waters react to the current state of water quality in the basin and tributaries (pH, concentration, discharge), the sediments exhibit a stable concentration character.

Acidic mine drainage (AMD) discharged from the abandoned Smolník mine (Pech shaft, Slovakia) contaminates surface water in the Smolník creek due to the decreasing pH and the production of heavy metals. Mixing AMD with surface waters results in an increase in pH, which affects the metal precipitation. Using statistical methods, the effect of pH on the concentration of selected metals (Fe, Mn, Al, Cu and Zn) in the water of the contaminated Smolník creek is described in this work. Polynomial curves were used to identify trends in pH and metal concentration in the surface water. The analysis showed that the second-degree polynomial functions as a candidate for explaining metals’ concentration based on the measured surface water’s pH with a goodness of model fit, based on a coefficient of determination ranging from 0.4 to 0.7 depending on the determined metal concentration and location.

The construction industry plays a significant role in resource consumption and environmental degradation, making it crucial to analyze the sustainability aspects of construction materials and their transportation processes. This paper focuses on conducting a life cycle assessment (LCA) analysis of building materials, specifically considering the environmental impacts associated with their transportation to construction sites. By incorporating the transport phase into the assessment, a more holistic understanding of the environmental implications of construction materials can be achieved. The study aims to quantify the environmental burdens of both material production and transportation, providing valuable insights for sustainable decision making in the construction industry. The analysis revealed that transport of building materials for the studied house by diesel lorry, covering a distance of 150 km, contributed 16% to climate change and a significant 53.5% to abiotic resource depletion. Additionally, it had a 15–18% impact on acidification and photo-oxidant formation. Full article

The construction sector produces more than 35% of the total amount of waste in Europe and for around 36% of emissions. This paper deals with the life cycle analysis of three alternatives of a residential building in terms of carbon footprint. At the same time, the analysis focuses on the end-of-life phase and its significance for the reduction of the carbon footprint. From the results obtained, it can be concluded that variant three has the lowest CO2eq/m2 emission levels compared to those of the other two variants. Based on the overall investigation of the end-of-life phase, this study found that the reuse of brick material contributed the most to the reduction of the overall emissions. Full article

The emergence of new biotechnologies has increased interest in the study of the impact of environmental contamination on microbial communities, particularly in relation to the potential benefits that stress-adapted microorganisms offer in environmental protection, industrial ecology, and mineral and waste processing. This study aimed to compare the bioaccumulation abilities of recently isolated microscopic fungi belonging to the genera Aspergillus, Phoma, Cystobasidium, Cladosporium and Exophiala. These fungi were isolated from a site contaminated with both toxic metals and organic pollutants. The study monitored the bioaccumulation of selected toxic metal ions (Cu(II), Zn(II), Ni(II), Cr(III), Pb(II)), as well as pH changes, over a 30-day of biomass growth. The medium containing Pb(II) exhibited a statistically significant pH change during the 30-day accumulation period (Mann-Whitney U Test, p < 0.05). These findings provide valuable insights for the potential industrial application of microscopic fungi in bioaccumulation processes. Full article

This study assesses the water quality of the Sušanecké Ponds in the Czech Republic post-mining area. Four monitoring profiles were chosen: the Sušanka River inflow into the Sušanecké Ponds, two ponds and the outflow of the Sušanecké Ponds to the Sušanka River. The sampling took place in a 14-day interval from March to October 2022. The monitored parameters were temperature, O2, pH, electrical conductivity, turbidity, nitrate nitrogen, ammoniacal nitrogen, total phosphorus, chlorophyll-a, CODCr, BOD5 and metals—Fe, Mn, Cu, Zn, Ni, Pb, Co, Cd, Cr. The results were evaluated in accordance with the Czech standard ČSN 75 7221 and Government Regulation No. 401/2015 Coll. Based on the evaluation data, it was found that the area of the Sušanecké Ponds does not meet the limits of the government regulation for three out of the twenty parameters. According to the standard, Sušanecké Ponds are mainly classified as highly polluted waters. Full article

This paper evaluates the washing interval of the rapid sand filter at the central drinking water treatment plant Nová Ves—Frýdlant nad Ostravicí in the Czech Republic (DWTP Nová Ves). The aim was to conduct automated flow cytometry measurements (FCM) and find the link between FCM and turbidity. The monitor parameters were the length of the wash cycle in hours, the flow rate of the filter and the production, the pumping of the recirculating wash water, and the physico-chemical and microbial analysis of the water samples. The focus of this paper is the detailed characteristics of the filtration mode evaluated during the summer and winter periods. During the measurements, it was confirmed that turbidity replicated the FCM data measured by the FC BactoSense instrument. Turbidity can be identified as one of the key features that can be related to the measurements made. Turbidity and the cell count itself are influenced, among other things, by the pumping of the return water, whereby an increase in the cell count can be observed after the pumping has stopped but gradually stabilizes at the values measured before pumping.

Two different solutions differing in their composition were tested against the following fungal phyto-pathogens: Cladosporium cladosporioides, Alternaria infectoria, Botrytis cinerea, Monilia fructigena, Aspergillus clavatus and Penicillium digitatum. The two different solutions were a fatty acid-based DPB solution and the development batch of a substance labeled M-decanocide. The tested species of fungal phyto-pathogens, namely Penicillium digitatum, Aspergillus clavatus and Cladosporium cladosporioides, grew rapidly and sporulated heavily on the agar plates with the product M-decanocide applied. In Aspergillus clavatus and Cladosporium cladosporioides cases, growth-free zones were formed around the cuts when the tested solution was applied, which confirmed its positive antifungal effect. The fungicidal effect of the tested DPB solution was not confirmed for the selected fungal phyto-pathogens. Full article

In the more contaminated northeastern region of the Czech Republic (Moravian-Silesian Region) in 2018 and 2019, soil samples and selected agricultural and forestry products were collected. The contamination of the environment was caused by radioactive cesium 137Cs from the nuclear Chernobyl disaster, and the activity concentration of 137Cs was determined in all soil samples taken, ranging from 0.177 Bq kg−1 dry matter (dm) to up to 299 Bq kg−1 dm, with an arithmetic mean of 38.4 Bq kg−1 dm. The activity concentrations of 137Cs of agricultural and forestry products ranged from <0.02 Bq kg−1 to 1390 Bq kg−1 dm, and the transfer factors calculated based on these varied from 0.011 to 31 with an arithmetic mean of 3.4, with the highest values found in forest ecosystem products. The transfer factors and annual committed effective dose was calculated. It was statistically proven that the level of soil contamination with 137Cs is related to the altitude and intensity of the precipitation in April and May of 1986, after the Chernobyl NPP accident.

The aim of our contribution is to evaluate the possibilities for the biochemical utilization of paper wastes. We tested aerobic and anaerobic degradation of paper waste sludges from a plant that processes recycled paper. Testing included the assessment of phytotoxicity. We can conclude that the concentration of paper sludges did not have toxic effects on the bacterial consortium of the anaerobic or aerobic conditions. However, the leachate of paper sludges and water from sludge dewatering had a slightly negative effect on the germination of cress (Lepidium sativum L.) and lettuce (Lepidium sativum L.) seeds where the germination ranged from 83.3% to 100% but the mass yield was higher.

The quality of wastewater greatly affects the aquatic environment. Currently, a significant amount of emerging pollutants are entering wastewater in the form of pharmaceutical contaminants, industrial chemicals, pesticides, toxins, etc. However, conventional wastewater treatment processes at WWTPs are not effective enough for these emerging pollutants. Therefore, emerging pollutants represent a significant source of wastewater pollution and associated pollution of surface water and even drinking water. The main sources of pharmaceutical contaminants are analgesics and anti-inflammatory drugs, and of these, the most common in wastewater are non-steroidal anti-inflammatory drugs (NSAIDs). The aim is to provide a comprehensive review of the available information on NSAIDs in the aquatic environment, i.e., their occurrence, effects on the environment, formation of main metabolites, and methods of NSAID removal, with a focus on current trends and possible directions for future research.

The aim of the work was to simulate a fire in the illegal waste dumps and to find out whether the used firewater represents a potential danger to the environment after its runoff into the surrounding area. Laboratory analysis confirmed the presence of heavy metals and other chemical compounds (nitrates, sulphates and chlorides). Given the results of the above analysis, we can state that the used firewater contains hazardous substances, which confirms the release of these substances into the water during extinguishing of waste-dump material. This thesis does not aim to criticize the tactical procedures of firefighters in extinguishing such fires, as their main goal is to eliminate waste-dump fires and eliminate the further spread of fire.

With the increasing prevalence of monitored micro-pollutants in the environment, new challenges arise in their determination. Currently, the issue of microplastics in the environment is a highly debated topic. This article focuses on the assessment of micro-particles in drinking water samples collected in the Czech Republic. The samples for analysis were collected at two locations, twice a day. Particle separation was achieved through vacuum filtration, and particle identification was performed using the µ-FTIR method. A total of 40 particles were analyzed, and their shape, color, and material composition were determined. The study results demonstrated the presence of microplastics and additives used in plastic production in the drinking water samples. The findings of this article contribute to understanding the issue of micro-particles in drinking water and raise questions for further research and measures to protect public health and the environment.

The paper deals with a proposal for a small-watercourse revitalization measure, which is currently regulated by a post-local treatment. The sections of the watercourse are relatively straight and direct. The current shape of the stream does not retain water in the landscape. Any surface water in the watercourse is quickly transferred to the receiving watercourse, which is the important Hvozdnice watercourse. The practical part includes the design of revitalization measures, a new longitudinal profile, and sections. The watercourse is loosened by curves and the total length of the watercourse has been extended by 161.56 m. The route includes a wetland, four pools, and two pond wedges.

This paper identifies the main factors that shape energy poverty. Based on the analysis of statistical, regulatory documentation, as well as the state of the housing stock in Portugal, a number of new factors have been identified that are inherent in developed countries. The factors that shape energy poverty include the low energy efficiency of buildings, lack of access to energy-efficient sources, imperfect regulatory framework in the construction sector, and low level of public awareness of loans to cover energy-related needs. In view of this, it can be argued that energy poverty is not a problem of Third World countries only but is a global problem that will become even more acute as we move to clean and energy-efficient resources. To overcome the problems of energy poverty, the experience of Portugal was analysed. It was found that the practice of granting loans to reimburse the cost of energy purchases is not effective. Based on the analysis of government programmes and plans in Portugal, it was found that one of the most effective ways to overcome energy poverty is to ensure the energy certification of buildings. The incentive for the transition to certification is a set of state programmes on construction loans, allocation of funds for modernisation, etc. The identified factors and tools for stimulating energy efficiency improvement allow us to formulate a strategy for overcoming energy poverty, which includes energy certification of buildings, transition to more efficient and energy-saving heating means, lending to the population, and allocation of funds for modernisation.

This article deals with the use of ash from biomass burning for the remediation of thermally active dump in Heřmanice, Czech Republic. Nowadays, various chemical, physical, or biological methods of remediation are used for the remediation of dumps. The authors discuss the complex use of ash from biomass as a possibility for biological remediation of the Heřmanice dump. The main advantage of obtaining ash when burning biomass is primarily the fact that it is a renewable energy source, which produces electricity and large amounts of ash, which can be used, for example, for the remediation of the Heřmanice dump. Tailings are characterized by their acidity, while fly ash is characterized by high alkalinity. This study deals with which ratio (tailings:ash) would achieve the necessary neutral values in order to prevent the release of heavy metals into the surroundings of the Heřmanice dump. The value of the active soil reaction (pH/H2O), the value of the exchange soil reaction (pH/CaCl2), the value of hydrolytic acidity (Ha), together with the value of soluble salts in the tailings, i.e., electrical conductivity, were also studied. Based on the obtained results, it can be concluded that the addition of biomass combustion ash had a positive effect on the pH value of the tailings. Based on this fact, Al3+ is excreted more slowly into the environment. A higher content of aluminum is toxic to plants, while in a smaller amount, its content is necessary and at the same time an important factor in the process of plant growth. The mixing of alkaline ash with unburned surface tailings from the thermally active Heřmanice dump significantly influenced its acidity, which had a positive effect on increasing the active and exchange acidity.

This article describes the resistance of chemically durable enamelled surfaces against the effects of chemical leachate and enzymes of bacteria Acidithiobacillus ferrooxidans, which are commonly used in biohydrometallurgy today during the biochemical leaching of ore. For many years now, the Vítkovice ENVI company has successfully used steel parts protected by the tested enamel in the construction of wastewater treatment plants and biogas stations. This article summarizes the results of a study that dealt with verifying the possibility of usage of widely applied enamel in the field of biochemical leaching during the treatment of raw materials. From the performed experiments, it follows that enamel can endure the effects of leaching solutions, but on poorly treated areas such as the edges and corners of parts, a quick onset of corrosion occurs.

This article addresses an important task for the operators of public water supply systems. It is to ensure the long-term security, reliability, and provision of the required quantity and prescribed quality of drinking water systems. To fulfill this task, a program called “Risk Assessment” has been developed. The risk assessment program for the drinking water supply system is incorporated into current legislation, which mandates that all operators of public water supply systems assess the waterworks that they operate. The objective of this article is to assess the risks of the drinking water supply system of the Nový Malín communal waterworks in accordance with the applicable legislation and recommended methodology. These waterworks constitute communal waterworks and encompass 7 underground water sources serving 3 municipalities and 7 settlements totaling 3500 residents. The results of this analysis should serve as a basis for updating the operational regulations of the waterworks and for assessing whether the methodology used is suitable for this type of water supply system.

Total mercury air pollution was evaluated in the former mining area of Gelnica (Slovakia) using tree bark, mosses (Climacium sp., Pleurosium sp.), and lichen (Pseudevernia sp.). Samples were collected (tree bark) and exposed (moss and lichen bags) on the heaps and near the mines. Additionally, the internal parts of the mines were evaluated. The mercury content in the bio-monitors was evaluated using an AMA-254 analyzer. The results showed significant differences in tree bark mercury content between the mines and heaps. The Hg content in mosses and lichens was not influenced by the type of mining work. The lichen Pseudevernia sp. was found to be the best Hg accumulator compared with mosses. Full article

During the production of pulp from natural raw materials, such as wood, large amounts of waste are generated. When they are reused, e.g., in agriculture, ecological requirements towards the environment must be met, and the associated risks must be known. In the framework of this study, the phytotoxicity of liquid waste generated during the industrial processing of pulp using the sulfite process was investigated. The results of semichronic toxicity tests on Lepidium sativum L. and Sinapis alba L. showed a direct effect on the growth and development of plants and proved that the undiluted samples were phytotoxic. However, the phytotoxicity of the investigated waste samples was influenced by their dilution ratio. Thus, finding the optimal solution ratio is crucial for the reuse of liquid waste. A nonphytotoxic effect on the roots of the tested plants was proven with a solution in a ratio of 1:100. In addition, the control samples diluted with a medium manifested phytotoxicity due to the activity of internal microorganisms. Full article

The article deals with the removal of 20 selected drugs from drinking water by sorption on granulated activated carbon. Two different sorption materials were used, and the efficiency of removing these micropollutants was compared. Experiments were performed in laboratory conditions with two different values of pH of water (7.8 and 6.5, respectively), at laboratory temperatures and with an identical amount of added sorbent (Filtrasorb 400, WG12). Standard additions were made to drinking water, and the final concentration of 0.44–0.55 µg/L of pharmaceuticals was utilized in the experiments. Samples were taken after 30, 60, 120 and 240 min of contact of sorbent with water. The LC-MS method was used to analyze the selected pharmaceuticals, which was performed at the ALS laboratory in Prague, Czech Republic. The adsorption efficiency of the removal of the given pharmaceuticals from water, as well as the adsorption capacity of the granulated activated carbon for the given pharmaceuticals, depends on amount of time that the water and material were in contact. The adsorption efficiency for two different types of granulated activated carbon ranges from 13 to 90%. Water pH also influences the sorption abilities of granulated activated carbon. Full article

Excessive consumption of cleaning and disinfecting agents, which constitute a distinct group of emergent pollutants known as PPCPs (“Pharmaceutical and Personal Care Products”), results in their accumulation in aquatic environments. Conventional wastewater treatment plants are unable to effectively remove the emergent pollutants that are present, including personal care product residues. This article focuses on the determination of surfactant substances in model samples prepared from selected personal care products and their biodegradability under laboratory-created aquatic ecosystem conditions. The conducted biodegradation processes, based on the monitored indicator (surfactants) in the model samples, confirm that the utilization of aquatic vegetation and gravel substrates can efficiently eliminate the present contaminants. Insights gained from researching the biodegradability of PPCP group products are applicable, including experiences with plant compositions used in aquatic environments, particularly in the construction of root-zone wastewater treatment systems.

This paper is focused on the permeability of cement composite samples with various admixtures. Permeability was examined by the rapid chloride permeability test due to the simple and relatively quick performance among the many methods. Permeability is one of the durability parameters considering the pore system of the composite structure. Ion diffusion provides information about inner pore structure by passing a charge through the sample. In real-life conditions, not only chlorides but also other ions can penetrate into the structure and cause corrosion. Various cement supplements were used as admixtures. The reference sample consisted of cement, fine sand, and water, while the rest of the samples consisted of 20% blast furnace slag, bypass dust, eggshells or recycled glass instead of the cement. The results showed lower permeability in samples containing blast furnace slag and eggshells and a higher charge passage in samples with recycled glass and bypass dust than for the reference sample.

The following article is intended as an introduction to ecotoxicology/wastewater toxicology, as this has currently become a widespread and highly discussed topic with scarce information available to date. With the beginning of the COVID-19 pandemic, when disinfectants began to be used in larger quantities, problems also began at wastewater treatment plants. This situation was the reason for beginning to monitor the ecotoxicity/toxicity of the wastewater flowing into the studied wastewater treatment plant; the wastewater treatment plant entered a state of emergency and was unable to treat the inflowing wastewater. In this critical period, the following parameters were monitored at the inflow of the wastewater treatment plant—BOD5, CHSKCr, NL, N-NH4, N-inorg, N-total, P-total, RAS and pH. The effluent from the wastewater treatment plant was also monitored for BOD5, CHSKCr, NL, N-NH4, N-NO3, N-NO2, N-inorg, N-total, P-total and RAS. Ecotoxicity (fish, barnacles, algae) and toxicity (Vibrio fischeri) were monitored at the inflow and outflow. Full article

The aim of this work was to evaluate the possibility of applying the dried biomass of E. gracilis var. bacillaris as a biosorbent for the removal of Cd. Experiments were carried out under conditions of batch systems involving aqueous solutions labelled with 109CdCl2. From the kinetics of Cd biosorption, it can be assumed that the Cd removal was a rapid process that achieved the concentration equilibrium of [Cd]biomass:[Cd]solution in the first minutes of the interaction. In individual experiments, the effect of solution pH, initial biosorbent, or Cd concentration was evaluated. According to MINEQL+ speciation modelling, it was found that the biosorption of Cd decreased linearly corresponding to a decrease in the proportion of Cd2+ in the solution. The biosorption data were well fitted to the Langmuir model of adsorption isotherm in comparison with the Freundlich model. The maximum biosorption capacity of the dried biomass of E. gracilis var. bacillaris for the removal of Cd was predicted and reached the value Qmax = 0.13 mmol/g or 14.1 mg/g (d.w.), respectively.

The aim of this study was to support the use of waste materials formed from a mixture of technogenic soils for growing plants through adding vermicompost leachates. The effect on the growth of underground and above-ground biomass was evaluated on plants of the bush variety of tomato (Solanum lycopersicum). Three different types of biodegradable waste (apple pomace, matolin, and horse manure) were used in the experiments, from which individual vermicomposts were subsequently produced. The effect of the addition of vermicompost leachates to the soil was manifested in all the statistically evaluated parameters of the bush tomato plants. It was found that the highest values were achieved for the root weight (+2.91 g; p < 0.01) and for the stem (+1.92 g, p < 0.01). The lowest values were observed in the control plants without application of the vermicompost leachates. Full article

This article is focused on analyzing roof structure from environmental impact indicators and circularity point of view. The life cycle analysis of the roof structure includes the product phase, transport from the factory gate to the site, operational energy and operational water phase, and an end-of-life phase. Three end-of-life scenarios for built-in materials are designed to observe the reduction in environmental impacts throughout the life cycle of the structure. Scenario 1 mainly considers waste incineration, which accounts for almost 77% of the end-of-life phase. In addition, landfilling (15.4%) and recycling (7.7%) are considered. In scenario 2, landfilling accounts for 38.5% and incineration also accounts for 38.5%. Recycling (15.4%) and downcycling (7.6%) are also considered. In scenario 3, recycling and reuse represent 46.1% and 38.5%, respectively. Incineration (7.7%) and downcycling (7.7%) are also considered. The lifetime considered is 50 years and the functional unit is 1 m2. One-Click LCA software was used for the analysis. Results for GWP-fossil are 415 kgCO2eq, 381 kgCO2qe and 362 kgCO2eq for scenarios 1, 2 and 3. The circulation score of the roof composition for three scenario is determined to be 2%, 16% and 36%. It can be concluded that the end-of-life phase of the materials influenced these results to a large extent. Full article

Stratigraphy was obtained by mathematical modeling of the electrical resistivity tomography results obtained in the study area. The interpretation of this information allowed us to know the structure of the soil and the levels at which the groundwater was located. Also, determining the optimal level of extraction of groundwater is a partition of 50 m depth onwards. Furthermore, the location of this water level will allow 1000 families in this area to obtain good quality water, reducing the water access gap that exists in the region and in Ecuador. Full article
