Vital research has been carried out on the sustainable organic fraction of municipal solid waste (OFMSW) stream management in the last five years. In addition to the traditional approach to reducing its environmental side effects, considering OFMSW as a feedstock to produce bioproducts, such as enzymes, bioplastics, biopesticides, and other high-value products, represents a key component in the transformation of OFMSW treatment plants (biogas or mechanical–biological treatment (MBT) plants) into biorefineries. This short review is intended to assess and analyze the current state of knowledge of OFMSW treatment technologies, suggest practical solution options, and identify future research and development needs to help promote more sustainable management of this underutilized and ever-growing waste stream.

The aim of the study was assessment of groundwater stabilization. Corrosive water effects on metals include complex electrochemical and biochemical processes. None of the water components remain indifferent to the metal and can accelerate or delay its corrosion. On the basis of the conducted tests of water samples, the aggressiveness and corrosivity indicators were calculated. Conducted research included analyses of raw and treated water. Raw water was taken as groundwater. Then it was treated in individual and complex processes such as aeration, filtration and ion exchange. Water aggressiveness and corrosion level were introduced by the Langelier Saturation Index (LSI), the Ryznar Stability Index (RI), the Larsoni–Skold Index (LI) and the Singley Index (SI). Obtained results proved that used water treatment processes must be improved through additional aeration and filtration with a dolomite bed. A simple system typical for industrial water is not enough to reach stable water because of remaining aggressiveness and corrosion. Full article

Solvents are a group of chemical compounds that are widely used in organic synthesis. Taking into account the chemical nature, solvents are divided into protic and aprotic ones. An attractive alternative to commonly used industrial extractive liquids is an anthropogenic, organosulfur medium—sulfolane. Sulfolane is a five-membered heterocyclic sulfur–organic compound from the group of sulfones (R-SO2-R’, where R/R’ is alkyl, alkenyl, or aryl), which contains an apolar hydrocarbon backbone and a polar functional group. It is a selective solvent in the liquid–liquid and liquid–vapor extraction processes used for the removal of close-boiling alkanes from cycloalkanes or for the separation of compounds with different degrees of saturation and polarity in the extractive rectification of arenes from non-aromatic saturated hydrocarbon mixtures. In standard conditions sulfolane is not an aggressive solvent for steel, but at higher temperature (170–180 °C) and oxygen availability, it may be decomposed and subsequently some corrosive (by-)products can be formed. The primary purpose of the presented pilot-case examination was to verify applicability of the industrial, multi-electrochemical technique for reliable detection of the corrosion processes in low conductive fluids.

Agricultural biogas plants are an investment that benefits both investors, inhabitants of a given region, as well as the natural environment. Such a project, despite many economic, environmental, and social advantages, is also associated with the emission of unpleasant odors or noise. That is why selecting the location of an agricultural biogas plant is a particularly important task. The investment location was selected using multicriteria decision-making (MCDA or MCDM) methods. Of the three variants, the most favorable in terms of the adopted criteria was selected using both analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) methods.

An analytical method that can allow one to determine simultaneously chosen organic micropollutants has been developed to measure their concentrations in water. Standard mixture of 16 polycyclic aromatic hydrocarbons (PAH) and nine polychlorinated biphenyls (PCB) was added to distilled water in a specific amount. The solid phase extraction (SPE) method was applied. Isopropyl alcohol and methanol were used to precondition SPE extraction columns. PAH and PCB were eluted from the column fillings using dichloromethane. Extracts were condensed to a volume of 2 mL. Prepared samples were analyzed with the use of gas chromatography and mass spectrometry. The achieved percent recovery of PAH was from around 7% in the case of chrysene to 100% in the case of naphthalene. The achieved percent recovery of PCB was from about 51% in the case of PCB 101 to 92% in the case of PCB 156. Full article

In order to fulfil the European Energy Performance of Buildings Directive (EPBD) requirements regarding the reduction of energy consumption in buildings, much attention has been paid to primary energy consumption. Wind energy is one type of primary energy. The analysis of the literature has revealed that wind energy is evaluated by different methods. Therefore, the aim of this article was to calculate the effect of the parameters of wind sources on the primary energy factor of wind turbines. In order to achieve this aim, the primary energy factor of 100 investigated wind turbines and 11 wind farms operating in Lithuania was calculated. Investigation results showed that the difference of the non-renewable primary energy factor between wind turbines due to capacity is 35%. This paper provides a recommendation with regard to EU energy efficiency and renewable energy directives and regulations: All EU member states should use the same or very similar methodology for the calculation of the primary energy factor of renewable and non-renewable energy sources.

The goal of the research was to assess the pollution level of water in the existing real water treatment station in Pelele in the municipality of Punsk. The station needed to be rebuilt because the equipment in operation there had not been changed for years. As part of the research efforts, a new water purification system was designed. The technology of the station is based on a two-stage water treatment system. Water picked up directly from the intake (raw water) as well as purified water at the old and new stations were analyzed. Then, the results obtained from water tests before and after modernization of the station were compared. There were such parameters analyzed as: color, turbidity, pH, iron (Fe), and Manganese (Mn). Through the conducted research and the results of pollution parameters received, the levels of Fe and Mn in raw as well as treated water were revealed. Their concentrations have proven that water coming from the new station continues not to be appropriate for human consumption just after the modernization process. Full article

Currently, polymer membranes are widely used in water treatment processes. The polymers commonly used for their production are polysulphone, polyacrylonitrile, or polyethersulphone. However, there are many other raw materials from which membranes can be prepared. In this work, polystyrene membranes were obtained by dissolving Styrofoam in dimethyleformamide. The surface properties of the obtained membranes differed slightly from those obtained for polymer membranes prepared from typical granulates. Retention testing in ultrafiltration conditions showed that membranes made form waste polystyrene have similar parameters to membranes made from pure polymers. Full article

Construction and using of buildings for many years produce long-lasting impacts on human health and the environment. Life cycle assessment (LCA) is the rapidly evolving science of clarifying these impacts in terms of their quality, severity, and duration. LCA of three selected new family houses located in Eastern Slovakia is performed with the aim to compare them in terms of built-in materials as well as used technologies. The main goal of the analysis is to investigate and underline the foreseeable reduction rate of environmental impacts resulting from applied green materials and green technologies. LCA impact categories of global warming potential (GWP), ozone depletion potential (ODP), acidification potential (AP), eutrophication potential (EP), and photochemical ozone creation potential (POCP) are selected for this analysis. Investigated family houses are built from conventional materials, such as aerated concrete blocks, reinforced concrete, thermal insulation of silicate mineral slabs, and roofing mineral wool, as well as natural materials, such as clay, straw, wood, cellulose, and vegetation roofs. Product phase contributes greatly to the GWP for houses built of conventional materials. AP, EP, ODP, and POCP impact categories are considerable also in the product phase. Even an operational energy phase contributes a large share of the negative impact on the environment. Adoption of green design and technology in buildings, which can mitigate negative impacts on the environment, has been recognized as a key step towards global sustainable development. The main goal of this article is to make the case that green buildings are important for reducing negative effects on the environment and resources, while simultaneously enhancing positive effects throughout the building life cycle.

The object of the research was surface water taken directly from the Mała Panew river. Zeta potential was measured in dependence of the inflicted coagulant dose. Four types of aluminum-based coagulants were used in this research: aluminum sulfate (Alum), polyaluminum chloride (PAC), dialuminum chloride pantahydroxide (PACl), and polyaluminum chloride hydroxide sulfate (PACS). Effective coagulant doses were selected on the basis of the zeta isoelectric point (IP) analysis. Coagulation efficiency analysis was based on the parameters of treated water (pH, turbidity, color, alkalinity), reduction of organic matter (Abs254, Total Organic Carbon (TOC) and Disolved Organic Carbon (DOC)), and residual aluminum contamination.

Ventilated façades are among the existing measures to reduce the energy demand in buildings. The combination of this passive heating and cooling strategy with photovoltaics (PV) can drive new buildings towards the current European targets for near or even net zero-energy buildings (nZEB). The present work aims at studying the PV integrated ventilated façade of the nZEB known as “LUCIA” at the University of Valladolid, Spain. First, the transmissivity of the PV façade is measured. Then, the monitoring of the available solar radiation is presented together with the air-dry bulb temperatures indoors, outdoors and inside the ventilated façade. The experimental results permit the validation of a mathematical model that describes the behaviour of the ventilated façade in its current operating modes. The results show that dampers should be closed during winter to let the façade act as a further insulation for outdoor temperatures below 18.4 C to improve energy efficiency. Indoor air recirculation would be helpful during 10% of the winter period. Full article

Inasmuch as the European Union promotes only energetically viable heat pumps in a given location, the aim of the work is an assessment of whether a ground-to-water heat pump (ground source heat pump: GSHP) can be considered as an ecological heat generator in Polish climatic conditions and those of the energy market. Here, as an estimator, the net seasonal coefficient of performance (SCOPnet) was selected. Estimation was done using 10-year temperature measurements. It was found that in heating mode SCOPnet value equaled 4.83, satisfying European Commission guidelines. According to the guidelines, the minimal SCOPnet value in Polish energy market conditions should exceed 3.5. CO2 emissions from the GSHP represented two-thirds of CO2 emissions of an air-to-water heat pump (air source heat pump: ASHP) in the same building. The ground heat pump thus meets the ecological heat generator conditions set by the European Commission. Full article

The presented research assumes the implementation of experimental studies on the occurrence of organic micropollutants in the pool water environment. The main goal of this paper is to identify micropollutants in swimming pools and select the “priority substances” due to their frequency of occurrence, concentration levels and health effects. The presence of micropollutants in swimming pools showed in this research raises the question whether current methods of swimming pool water treatment provide such properties that do not pose a threat to the health of users.

A series of Bi4O5Br2 photocatalysts were prepared via an innovation method of synthesis with ionic liquids (ILs). The crystal structures were investigated by X-ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR). The Field Emission Scanning Electron Microscope (FE-SEM) images illustrated the unique structure of prepared photocatalysts. The photocatalysts were also characterized by N2 adsorption-desorption analysis, X-ray photoelectron spectroscopy (XPS), UV-vis diffuse reflectance spectra (UV-vis/DRS) and photoluminescence spectra (PL). The role of ILs in synthesis of Bi4O5Br2 on morphology and photocatalytic properties were investigated. Rhodamine B, 5-fluorouracil and chromium (VI) were used as the model micropollutants to evaluated adsorption capacity, photooxidation and photoreduction ability of prepared Bi4O5Br2 under artificial solar light. This work provided a new thought for enhanced photocatalytic activity of bismuth oxybromide photocatalysts. Full article

The aim of the research presented in this article was to present the possibilities of wastewater treatment coming from the confectionery plant using pressure membrane techniques. Nanofiltration was carried out in a pressure dead-end filtration set up (Osmonics type GH-100-400) with a cell capacity of 350 cm3 equipped with a magnetic stirrer. Four flat nanofiltration membranes were used during the tests. The efficiency of the process was estimated by determining the purified wastewater volumetric stream and based on the removal degree of pollution load. The nanofiltration membrane, thanks to which the highest cleaning results were obtained, is a flat composite membrane, with the symbol NF-270, with the polyamide film layer of the Dow Filmtec company. The degree of removal of COD after nanofiltration in this membrane was 98.7%. It was found, that wastewater treated by pressure membrane techniques in the confectionery industry can be reused, for example, for irrigation of agricultural land or gardens, and for machines and equipment washing (closing water circuits). The use of NF processes enables wastewater treatment to such a degree that it can be drained to a natural receiver. Full article

The phenomena of stabilization and flocculation through the addition of polymer is widely used in many branches of industry, e.g., agriculture. Due to the high strength of intermolecular bonding, the polymers are used as an additive to control the process of soil erosion. Flocculants strengthen the soil cohesion, which limits the transport of sediments and thus the process of soil structure degradation. Also, the presence of polymers affects the increase of water infiltration into the soil and dissolved substances, including toxic compounds. Therefore, the presence of soil flocculants may influence the occurrence of heavy metal accumulation. The aim of the study was to investigate the influence of the presence of cationic polyacrylamide on lead(II) ion adsorption onto the surface of montmorillonite. The effect of cationic group content in the polymeric macromolecules, the addition order of individual adsorbates, and the lead(II) ion concentration were also determined. Full article

This study was carried out in the Boukhalef River which reaches the western coastal waters of Tangier, Morocco, loaded with wastewaters from two industrial zones: Tangier Free Zone and Gzenaya Zone. To understand the extensive impact of these industrial zones on Jbila and Sidikacem beaches located near the Boukhalef River mouth, water and sediment samples of the Boukhalef River were examined in terms of physical–chemical and heavy metal parameters, respectively. The results showed high values of conductivity (Cond), biochemical oxygen demand in five days (BOD5), and chemical oxygen demand (COD), which are the causes for the very bad quality status of the Boukhalef River waters. The application of principal component analysis on the heavy metal results of Boukhalef waters and sediments showed that samples were characterized by a load of heavy metals, seemingly of the same anthropogenic origin. This analytical survey demonstrated a relationship between the bathing water quality and industrial discharge. Indeed, industrial zones represent a strong source of pollution in the west coast of Tangier, Morocco. Full article

Wastewater generated in the soda ash production process can be characterized by a strong alkaline reaction, high electrolytic conductivity and high concentration of chlorides, ammonia, sulphates, phosphates, calcium, potassium, sodium and magnesium. Protection of water against pollution should be not only connected with rational management of water resources and the restoration of the water environment to the required state, but also with prevention of pollution. It is an increasingly important element of protective measures. The strict control of pollution at the source is important. Therefore, it is necessary to develop methods of broadly defined waste disposal from industry. The article presents the results of research aimed at the removal of sodium, calcium, potassium, magnesium and ammonium ions from wastewater from soda ash production using three sorbents: Halosorb, Compakt and Damsorb K. The ion removal process was carried out dynamically with different load on the deposit. The concentration of all these anions was reduced to some extent, which indicates the possibility of further, more accurate tests. It was found that the type of sorbent does not differentiate the results of the experiment. The load on the deposit, on the other hand, has an impact on the efficiency of sorbents in wastewater treatment. Full article

The aim of this article is to study the effect of low-frequency ultrasound on the disintegration of microorganisms present in mixed sewage sludge. Initial and excessive sewage sludge were used for examinations coming from the Bialystok Sewage Treatment Plant. They were exposed to ultrasound at 20 and 40 kHz, in varying sonification times and in the case of variable operation of the ultrasonic cleaner (continuous and pulsating work). Research showed that ultrasound was demonstrating effective action with the tested microorganisms. The 30-minute interaction of ultrasounds at 20 kHz on the bacteria present in sewage sludge resulted in a significant decrease in the number of these microorganisms. The obtained results, therefore, indicate the possibility of using this method to disintegrate microorganisms in municipal wastewater treatment plants. Full article

The paper production is developed throughout the world, therefore, more paper sludge waste (PSw) is accumulating. The aim of this work was to determine the properties of PSw burned at 900 °C and its impact on physical–mechanical properties of cementitious matrix and evaluate its usage/utilization possibilities in cementitious materials. For the implementation of the aim, cement-based specimens were prepared and their –mechanical properties were determined. Specimens from five compositions were formed, with 2.5%, 5%, 7.5%, and 10% of the cement by weight replaced with PSw. When 5% of the cement was replaced with PSw, the compressive strength increased by approximately 7%, although density and ultrasound velocity slightly decreased (up to 1.5%). When 7.5% PSw was added, the compressive strength of the specimens decreased. To summarize, it can be stated that up to 5% PSw may be utilized/used for the preparation of cementitious mixtures. The usage of the waste allows environment conservation, reduced amount of cement in mixtures, and improvement of properties of cementitious materials. Full article

Moreover, the greatest part of this time is spent in lack of awareness, so it is important to maintain suitable conditions in these areas, including air quality. In non-ventilated bedrooms, people may have trouble falling asleep, may not be resting enough during sleep, and they can wake up tired. This affects their well-being and behavior throughout the next day. Indoor air quality measurements were carried out in a single-family home bedroom. The measurements were made in unsealed windows. In the bedroom under examination, where people stay only during the night and where the door is always open and air is constantly being renewed, the carbon dioxide concentration during the night exceeded the permissible standard—1000 ppm.

This article presents a new way of determining the annual energy output of solar thermal collectors. The proposed method, in the first stage, assumes the creation of a database that contains energy gains QSC from the solar collectors, the average annual solar irradiance intensity IS, and the average temperature of the outside air θO. It can be made on the basis of detailed computer simulations. In the current case, EnergyPlus software was used to create this database. Next, mathematical relations for flat plate and evacuated tube collectors were developed using the linear regression analysis (multiple regression method). Based on these equations, one can calculate the value of QSC as a function of IS and O. In addition, two graphs for the estimation of the annual energy gains for the entire area of Poland and for the conditions of a typical meteorological year were prepared. Full article

This research aims to show the advisability of usage of selected renewable energy sources for domestic hot water (DHW) installations in buildings located in Poland and Spain. The analysis was conducted for a typical kindergarten, an example of buildings with high density of people and stable profile of usage, as opposed to schools which are closed during summer holidays. We took into account national regulations to estimate heat demand. Then applying solar collectors and heat pumps to use as a monovalent energy sources were considered. The total cost of the system with solar collectors in Poland was found to be 1.4 times higher than in Spain, whereas the difference in a case of air heat pumps was 18%. Moreover efficiency of solar collector and heat pump systems were found as 49.56% for Warsaw, 52.29% for Madrid with coefficient of performance (COP) 2.2 and 2.55 respectively, therefore simple payback time (SPBT) of investment was estimated in a range between 6–12 years for solar collectors and 5–6 years for heat pumps.

The aim of the research was to determine the effectiveness of removing micro-organic pollutants, including PAHs, using the modified Fenton method. The tested material was pretreated coke wastewater, in which the initial chemical oxygen demand (COD) value and initial polycyclic aromatic hydrocarbons (PAHs) concentration were determined. The samples were then subjected to an oxidation procedure. Before the process, the pH was adjusted to 3.5–3.8. Next, the following doses of sodium carbonate—hydrogen peroxide (2/3): 1.2 g/L, 1.5 g/L and 2 g/L, and a constant dose of iron sulphate were added. The next step was exposing the samples to UV light for 6 min and separating the organic matrix from the samples of wastewater. After the tests, the final value of the COD and the final PAHs concentration were determined. The average content of organic pollutants in pretreated coke wastewater determined by the COD index was 538 mg/L, and after the oxidation process, the COD index decreased in the range from 9 to 29%. The efficiency of the degradation of the sum of 16 PAHs was varied and was in the range of 94–97.6%. The research results show that sodium carbonate—hydrogen peroxide (2/3) can be used for the degradation of organic pollutants, such as PAHs, in the modified Fenton process. Full article

The purpose of this paper is to determine the influence of color temperature of Light Emitting Diode (LED) diodes and illumination intensity on the content of photosynthetic pigments of chlorophyll a, chlorophyll b and carotenoids in Chlorella vulgaris algae cells. Choosing the right color temperature and intensity of illumination can favorably affect the growth of algae. In particular, it can contribute to the efficiency of the photosynthesis process and the amount of produced biomass from Chlorella vulgaris algae. In the spectrophotometric studies, the highest content of chlorophyll a, chlorophyll b and carotenoids was found in cultures illuminated with very cold white light (8500 K) with an intensity of 500 μmol/m2s. The highest measured content of chlorophyll a (Chl a) pigments was 48.29 mg/L, Chl b pigment was 23.25 mg/L and carotenoids pigment was 12.65 mg/L; the smallest content of pigments for Chl a (11.48 mg/L), Chl b (4.69 mg/L) and carotenoids (3.03 mg/L) was found in the sample illuminated with warm white light (3200 K) with an intensity of 50 μmol/m2s. The highest amount of dry organic matter amounting to 2.0 g/L was found in a sample illuminated with warm white light (3200 K) with an intensity of 250 μmol/m2s, then 1.91 g dry organic mass (DOM)/L for very cold white light with an intensity of 250 μmol/m2s, and 1.48 g DOM/L for very cold white light with an intensity of 50 μmol/m2s. The obtained results show that a higher content of photosynthetic pigments does not directly affect the increase of the amount of dry organic matter. Full article

For the realization of a near-zero energy building (NZEB) school, it is important to define during the preliminary phase of the design process the type of solar shading to be used for each orientation (south, east, and west), as it strongly determines the appearance of the façade of the building. Given that this choice is also strictly linked to the energy balance of the building and to the thermal-hygrometric and visual wellbeing of occupants, it is necessary to combine both aspects. This study aims to analyze and optimize the solar shadings system of one of the new typological models for kindergarten in order to minimize the energy needs of the building. The proposed analysis in the paper is part of a broader work aimed at defining qualitative and quantitative guidelines for the design of NZEB kindergartens and elementary schools in the Mediterranean area.

Packaging waste that is not recycled or reused has a negative environmental effects and presents serious concern. At the same time, various secondary raw materials, which were used to produce packaging from recycled materials, can affect human health and the environment because they can contain harmful chemical substances. For this reason, it is necessary to investigate the existence of hazardous chemicals in recycled materials. This paper analyzes issues related to the production of packaging by using materials from recycled packaging waste with a focus on the influence of the hazardous substances that the waste may contain. This paper presents the results of a survey interviewing packaging manufacturers who use recycled materials in packaging, revealing problems that packaging manufacturers face in the manufacturing of packaging from recycled materials.

This paper presents a short overview of the removal rates of selected organic micropollutants and the formation of their intermediates in water solutions during the processes of photolysis and photocaltalysis. Both processes were carried out using four UV lamps with different irradiation spectra. It was proven that the distribution of radiation intensity at given wavelengths had a strong impact on the decomposition of compounds. The most commonly used TQ mercury UV lamp led to the formation of a larger number of intermediates during photochemical processes compared to other UV lamps with the same power of 150 watts. Toxicological analysis indicated the toxic nature of some of the newly formed by-products. Full article

Pollution of water by toxic elements is one of the major factors of concern for human health, as well as for environmental quality, and draws a large amount of scientific attention. New and cheaper methods of wastewater treatment are increasing the quality of the environment and reducing the negative impacts on fauna, flora, and human beings. The sorption technique is considered a cost effective method for effectively removing heavy metals. During the past few years, there have been increasing studies dedicated to using low-cost adsorbents like bark, tannin-rich materials, lignin, chitosan peat moss, and sawdust. The presented paper describes the adsorption behavior of spruce wood sawdust. In order to determine its applicability for wastewater treatment, copper removal from model solutions was studied.

Buildings are significant contributors to energy-related sustainability challenges and a sustainable future. Practice shows—that the traditional building design process is becoming ineffective and will no longer be able to meet the determined requirements and standards of low energy architecture. The aim of this research is to introduce and validate the newly developed technology of building design concept, which integrates Quality Function Deployment (QFD) and Axiomatic Design (AD) methods. The proposed technology eliminates the traditional building design problems, ensures a smooth Integrated Building Design (IBD) process and matches the needs of the customer and the whole building design team. The new technology also provides a quicker and more effective way to find a sustainable and customer-orientated solution. Validation of the technology on the case study has shown that the energy functionality of the building proved to be superior to buildings, created during traditional building design process.

The aim of the study was to develop a nationally universal method for estimating the solar resources and to assess, at the municipality scale, the suitability for photovoltaic development based on the implementation of GIS&T (Geographic Information Science and Technology), multi-criteria analyses, and spatial data gathered from the National Geodetic and Cartographic Resources. The developed method is based on the use of digital topographic data and data gathered by means of modern remote sensing methods as a point cloud from airborne laser scanning. Based on studies in the literature, the formal and legal conditions applicable in Poland were discussed. The sets of constraints and factor criteria have been created as a base for evaluating the suitability of a chosen municipality for photovoltaic farms’ emplacement. Weight calculations in a multi-criteria method—an AHP method (analytic hierarchy process)—were applied. In the multi-criteria analysis, 27 constraints and 13 factors were included. Undoubtedly, a utilitarian feature of the developed method is the calculation models allowing full automation of the process of spatial assessment of municipality territories for photovoltaic farms’ development. Furthermore, calculation models can be easily adapted to some specific conditions that occur in the analyzed municipality territories. The results obtained confirm the significant usefulness of the implemented approach in the context of the spatial suitability assessment of photovoltaic development at the municipality scale.

The aim of the paper was to conduct an indoor air quality (IAQ) assessment in an auto repair shop, measuring CO2 and CO concentrations. Carbon monoxide and carbon dioxide concentrations were measured for a week. Two Testo 435-4 gauges were located at head height of an adult person (ca. 170 cm above the floor) in a room. The CO2 concentration was measured with an IAQ probe, which measures dew point temperature, psychrometer temperature and absolute pressure in indoor air. The second gauge was connected to a CO probe. Measurements were taken every 5 min and were averaged across an hour. Uncertainties were estimated using square-root combinations of fixed errors and random errors at a 0.05 level of statistical significance. The measurements were conducted from 17 November to 23 November 2018. The following graphs were plotted for carbon dioxide and carbon monoxide: hourly averaged concentration and 8 h averaged concentration. The results were discussed and compared to Polish, foreign and international standards and recommendations. It was found that the auto shop was in danger of negligence according to Polish law as well as nonfulfillment of healthy recommendations. An exhaust extraction system should be installed.

Colored industrial wastewater is a threat in many environmental aspects. As such, there is a need to find more effective methods for its purification. This article presents a brief overview of available methods for removing dyes from aqueous solutions, among them the adsorption process, which is the subject of this study. The course of preliminary tests on the process of cleaning dye solutions in the adsorption process is presented. Unmodified magnetite and magnetite modified with polymers were used as adsorbents. The synthesis of particular types of magnetite, the adsorption process, as well as the methods of further analyzes are described. As part of the work, the focus was put on a comparison of the effectiveness of the purification process for different types of adsorbents in relation to selected dyes. The varied conditions of the process were also analyzed. It has been shown that magnetite is an adsorbent that is easy to use, allowing effective separation of dyes of various chemical structures from aqueous solutions. The effectiveness of the process depends on the type of dye and on the pH value and can be increased in relation to some dyes by using magnetite modification with selected polymers. Full article

Chromatographic separation and mass spectrometer detection conditions were optimized to achieve the best micropollutants separation and the best detection sensitivity. A calibration curves were created at different calibration levels suited of each type of detection mode (Full Scan and Selected Ion Monitoring) and limits of detection (LOD) and limits of quantification (LOQ) were calculated. Furthermore, recovery values were determined for each compound in spiked water samples at levels equal to 10%, 50%, and 90% of the calibration curve range and compared to other studies in which similar methods of determination were used.

This paper presents the hydrodynamic parameter values of a large pool fish pass joined with block ramps in the Trzebuńka stream. The aim of this work is to evaluate the large pool fish pass patency in terms of fish and to answer the question of whether fish migration upstream is possible. The assessment of hydrodynamic parameters was carried out on the basis of water flow velocity measurements using a flow tracker device and by calculating the following parameters: Water depth, shear stresses, and Froude’s and Reynold’s numbers. Velocity measurements were carried out in 23–30 hydrometric points which were determined in each of the pools. A survey was done using the Topcon GTS-226 (Topcon Corporation, Tokyo, Japan) total station. The data were processed in order to obtain the results of hydrodynamic parameters prevailing in flowing water. The graphs were prepared using the Grapher 11 software, showing the distribution of individual hydrodynamic parameters for fish pass chambers and overflows in the fish passage. We concluded that the fish pass in Stróża was designed and constructed correctly. However, from a technical point of view, some deficiencies could be found. Full article
