    Opis:
    Results of the study into photodegradation of 2,4,6-trichlorophenol and pentachlorophenol in aqueous solutions have been presented. Quantum yields and rate constants of the reactions were determined. Intermediate products were identified by GC/MS method. The experiments confirmed formation of polychlorinated dibenzo-p-dioxins and dibenzofurans in photochemical reactions. The findings showed that formation of polychlorinated dibenzo-p-dioxins, and mainly octachlorodibenzo-p- -dioxin, is privileged in the studied reactions when compared to polychlorinated dibenzofurans regardless of the number of chlorine atoms in the molecule. It was also established that increase in the number of chlorine atoms in a molecule resulted in higher chemical efficiency of the reaction.

    Opis:
    The paper presents current reports on kinetics and mechanisms of reactions with mercury which take place in the exhaust gases, discharged from the processes of combustion of solid fuels (coals). The three main stages were considered. The first one, when thermal decomposition of Hg components takes place together with formation of elemental mercury (Hg0). The second one with homogeneous oxidation of Hg0 to Hg2+ by other active components of exhaust gases (e.g. HCl). The third one with heterogeneous reactions of gaseous mercury (the both - elemental and oxidised Hg) and solid particles of fly ash, leading to generation of particulate-bound mercury (Hgp). Influence of exhaust components and their concentrations, temperature and retention time on the efficiency of mercury oxidation was determined. The issues concerning physical (gas-solid) and chemical speciation of mercury (fractionation Hg0-Hg2+) as well as factors which have influence on the mercury speciation in exhaust gases are discussed in detail.

    Opis:
    The paper presents the effect of UV radiation of 254 nmwavelength on the mutagenic activity of aquatic solutions of 3-chlorophenol (3-CP), 2,4-dichlorophenol (PCP), 2,4,6-trichlorophenol (2,4,6-TCP) and pentachlorophenol (PCP). Mutagenicity studies were carried out on two Salmonella strains: TA98 and TA100, with and without metabolic activation by S9 mix. Stable intermediate products of photodegradation have been identified using the GC/MS method. Chlorophenols in doses below 0.1µg were strongly mutagenic towards both strains: TA98 and TA100. The mutagenic properties of aquatic solutions of chlorophenols for both strains decreased as follows: PCP>=2,4-DCP>2,4,6-TCP>3-CP. Aquatic solutions of three chlorophenols after their photodegradation were non-mutagenic for both bacterial strains, except for 2,4-dichlorophenol. In the case of this compound, the products of its decomposition were more mutagenic for the TA100 strain. No significant metabolic activation by S9 mix was observed which suggests a direct mutagenic impact of chlorophenols on the tested Salmonella strains.

    Opis:
    The paper presents two sample preparation procedures for the determination of aldehydes in wet deposition. In both cases the 2,4-dinitrophenylhydrazine derivatization and solid phase extraction were applied. The derivatization in method A was applied before the extraction, the extraction in method B was carried out with simultaneous derivatisation. Accuracy of both methods was evaluated on the basis of the analysis of aqueous solutions of selected carbonyl compounds. Both methods were characterized by good recovery, however, due to the precision of the method expressed as RSD for testing of environmental samples the method B was used. The analysis of environmental samples showed significant differences in the concentrations of aldehydes in wet deposition, depending on the location of the sampling point. In the case of samples taken from agricultural areas the predominant aldehydes were formaldehyde and acetaldehyde. Formaldehyde was from 31% to 47% of the determined compounds. While in samples collected near a traffic source, in the deposition acrolein was determined at the levels from 62% to 64% of the identified compounds.
    W pracy przedstawiono dwie procedury przygotowania próbek mokrej depozycji do oznaczeń aldehydów. W obydwóch przypadkach zastosowano derywatyzację 2,4-dinitrofenylohydrazyną oraz ekstrakcję do fazy stałej. W metodzie A derywatyzacja poprzedzała ekstrakcję, w metodzie B ekstrakcję prowadzono z równoczesną derywatyzacją. Na podstawie analiz wodnych roztworów wybranych związków karbonylowych oceniono precyzję obydwóch metod. Ze względu na odzysk oraz wartość względnego odchylenia do analiz próbek środowiskowych pobranych z obszarów silnie uprzemysłowionych i rolniczych wybrano metodę B. Analiza próbek środowiskowych wykazała znaczne zróżnicowanie stężeń aldehydów w mokrej depozycji w zależności od lokalizacji punktu pobierania próbek. W przypadku próbek pobranych z obszarów rolniczych dominującymi aldehydami były formaldehyd i acetaldehyd. Formaldehyd stanowił od 31% do 47% oznaczonych związków. Podczas gdy w próbkach pobranych w pobliżu źródeł komunikacyjnych w depozycji stwierdzono udział akroleiny w oznaczonych aldehydach na poziomie od 62% do 64% oznaczonych związków.

    Opis:
    Comparison studies have been performed on determination of total mercury in wet deposition by two analytical methods. The studies were carried out in the period of March to November 2009 at the sampling point located near intensive traffic in Southern Poland (Zabrze). The difference between these two methods consisted in preparation of samples for analysis and in the type of measuring device. In both cases, the method of cold vapour atomic absorption spectrometry (CV-AAS) after reduction of SnCl2 was used by means of a mercury analyzer model MA-2 produced by Nippon Instruments Corp. or of a mercury analyzer RA-915+ produced by LUMEX. Good agreement of the results have been obtained (relative error of the determination between the methods varied from 18% to 40%). Both analytical methods can be considered equivalent and used as a reference to each other. Quantity assessment of mercury wet deposition in southern Poland is lower than in 90 s, but still much higher in comparison with other countries in Europe and worldwide (ca. 30 μg·m -2·year -1.

    Opis:
    The content of polycyclic aromatic hydrocarbons (PAHs) in water and sediments of the Blachownia reservoir (South Poland) was investigated. Spatial variability of PAH concentrations in the longitudinal profile of the tank was determined. PAHs in samples were determined by gas chromatography coupled with mass spectrometric detection (GC-MS QP-2010 Plus Shimadzu) using an internal standard. Concentrations ranged from 0.103 μg/L to 2.667 μg/L (Σ16 PAHs) in water samples and from 2.329 mg/kg d.w. to 9.078 mg/kg d.w. (Σ16 PAHs) in sediment samples. A pollution balance was calculated and it was estimated that the inflow load was 17.70 kg PAHs during the year and the outflow load was 9.30 kg PAHs per year. Accumulation of about 50% of the annual PAH loads (8.90 kg) is a threat to the ecological condition of the ecosystem. It was calculated that the PAH loads in bottom sediment were about 80 kg, which limits their economic use. Improvement of the ecological status of this type of reservoir can be achieved by removing the sediment. Analysis of the diagnostic ratios obtained for selected PAHs showed that the potential sources of PAH emissions in small agricultural–forest catchments can be combustion of a coal, wood, plant material (low emission, forest fi res, burning grass, etc.). Transportation is also significant.
    Zbadano zawartość wielopierścieniowych węglowodorów aromatycznych (WWA) w wodzie i osadach dennych zbiornika Blachownia (południowa Polska). Określono przestrzenną zmienność stężeń WWA w profilu podłużnym zbiornika. WWA w próbkach oznaczano metodą chromatografii gazowej sprzężonej z detektorem mas (GC-MS QP-2010 Plus Shimadzu) z użyciem wzorca wewnętrznego. Stężenia wahały się od 0.103 μg/L do 2.667 μg/L (Σ16 WWA), w próbkach wody oraz od 2.329 mg/kg s.m. do 9.078 mg/kg s.m. (Σ16 WWA), w próbkach osadów dennych. Sporządzono bilans zanieczyszczeń i na tej podstawie oszacowano, że ładunek WWA wprowadzany do zbiornika w ciągu roku wynosi 17.70 kg WWA, a ładunek odpływający–9.30 kg/rok WWA. Kumulacja około 50% rocznego ładunku WWA (8.90 kg) stanowi zagrożenie dla stanu ekologicznego tego ekosystemu. Obliczono, że ładunek WWA w osadzie dennym badanego zbiornika wynosi około 80 kg, co ogranicza jego gospodarcze wykorzystanie. Poprawę stanu ekologicznego tego rodzaju zbiornika można osiągnąć poprzez usunięcie osadów. Analiza uzyskanych wartości wskaźników diagnostycznych dla określonych WWA wykazała, że potencjalnymi źródłami emisji WWA w niewielkich zlewniach o charakterze rolniczo-leśnym mogą być procesy związane ze spalaniem węgla, drewna, materiału roślinnego (niska emisja, pożary lasów, palenie trawy itp.). Znaczący wpływ wywiera również komunikacja.

    Opis:
    The aim of the research conducted in the conditions of Lower Silesia in the years 2012-2016 was to evaluate the growth and yielding of young peach trees cultivated in ridges with drip irrigation. The experiment concerned the flat-fruit peach trees, cultivar Saturn on the Manchurian peach tree seedling, planted in the spring of 2012 in the spacing 4.0 x 1.5 m. In each year the shortage of rainfall was observed, as compared to the years 1997-2000. During the vegetation period, the deficiencies were from - 7.3 mm up to - 221.7 mm. The insufficient amount of rainfall was accompanied by the rise of the mean air temperature in the vegetation period by 0.5 - 1.7°C. In the orchard, the drip irrigation in the form of stippling tape T-Tape TSX515-50-380 was applied, with the emitters every 50 cm and the expenditure of 3.8 l per metre in 1 hour. The humidity measurements were being taken from the beginning of May until the end of July with the use of Watermark probes, testing the sucking power of soil at the depth of 20 cm. The irrigation started when the water potential of soil was 30 kPa. During the 4 years, the total yield per hectare from the irrigated trees was by 5 t bigger than in the case of the trees that had not been irrigated. The irrigated trees cultivated in ridges had a tendency to more intensive radial growth. As far as the radial increase is concerned, statistically significant differences were noticed between the autumn of 2012 and the autumn of 2016. The application of irrigation also stimulated the elongation but only in the first two years of cultivation. The mean rate of proliferacy for the 4 years of fruiting was higher in the case of irrigated trees.

    Opis:
    Spring frost in the blooming time can be a significant factor decreasing the fruit production and affects the cultivation profitability in the years with unfavourable weather conditions. In Poland, the fruit trees especially susceptible to damage are peach and apricot trees. Among the popular methods of protecting the trees against spring frost damage there are three kinds of treatment: sprinkling irrigation, fogging, smoking and using fans for mixing the layers of air. The costs of applying the particular methods differ, as well as their efficiency. The side effect of using them can be also orchard pollution. The experiment was conducted on selected peach tree cultivars, on two rootstocks. Two methods of spring frost protection were applied: sprinkling irrigation and fogging with the use of glycerin mixed with tap water in proportion 1:10. Sprinkling irrigation proved to be more effective, it protected 98% of blooms. Using the fogging device also brought a satisfying effect. The cultivars that were easily damaged by spring frost were ‘Early Redhaven’ and ‘Cresthaven’. The greatest resistance to bloom damage was observed in the case of the ‘Suncrest’ and ‘Saturn’ trees. The yielding of the ‘Inka’ and ‘Early Redhaven’ trees protected by sprinkling irrigation was significantly better, as compared with the fogged trees. The mean fruit weight was determined mainly by the cultivar.

    The oscillations of electrochemical potential difference between aqueous phases of a liquid membrane oscillator containing cationic surfactant are presented. By UV-VIS spectroscopy, the concentrations of liquid membrane components (nitrobenzene and picric acid) in the both aqueous phases were established during the oscillation process. It was shown that nitrobenzene molecules are transferred to the aqueous phases from the beginning of that dynamic process. Picric acid molecules are not observed in the donor phase, meanwhile, from the beginning of the process they are transported to the acceptor phase. It can be concluded that the transport of the liquid membrane components to the aqueous phases is not responsible for the observed oscillations of electrochemical potential difference.

    Opis:
    Introduction. Periodontitis is a disease of multifactorial etiology and complex clinical manifestation. Removal of subgingival bacterial biofilm is a fundamental procedure in the treatment of periodontitis. Scaling and root planing (SRP) is currently the gold standard in the treatment of periodontitis, but in some cases such a procedure does not provide satisfactory results. The use of lasers in the treatment of periodontitis is one of the alternative adjunctive methods that has recently become more popular. Objective. The aim of the study was to evaluate the effectiveness of diode lasers in the treatment of periodontitis, based on the literature found in the Medline, Pubmed and Scopus databases published from June 2013 – June 2020. Results were based on a comparison of the effectiveness of SRP treatment in combination with photodynamic therapy or SRP in combination with laser irradiation of periodontal pockets. Results. The majority of studies confirmed the effectiveness of periodontal treatment combining SRP with photodynamic therapy or SRP with laser irradiation, compared to an SRP alone. Conclusions. Based on the recent literature, it can be concluded that SRP combined with photodynamic therapy or SRP in combination with a diode laser irradiation are effective methods to improve the outcomes of non-surgical periodontal treatment.

    Opis:
    Purpose In this paper, the application of Umberto NXT LCA software to devise a Material and Energy Flow Analyses (MEFA) for the technology of producing electricity from gas extracted in the process of shaftless underground coal gasification is presented. The Material Flow Analyses of underground coal gasification includes a range of technology, through obtaining process gas and its purification, to electricity production, and, additionally, the capture of carbon dioxide. Methods To evaluate electricity production based on Underground Coal Gasification, Material and Energy Flow Analyses (MEFA) was used. Modeling material and energy flow helps a high level of efficiency or technology of a given process to be reached, through the effective use of resources and energy, or waste management. The applied software for modeling material flow enables, not only, the simulation of industrial processes, but also the simulation of any process with a material or energy flow, e.g. in agriculture. Results MEFA enabled the visualization of material and energy flow between individual unit processes of the technology of electricity production from UCG gas. An analysis of material and energy flow networks presented in the form of Sankey diagrams enabled the identification of unit processes with the biggest consumption of raw materials and energy, and the greatest amount of emissions to the environment. Practical implications Thanks to applying material and energy flow networks with Umberto software, it is possible to visualize the flow of materials and energy in an analyzed system (process/technology). The visualization can be presented in the form of an inventory list of input and output data, or in the form of a Sankey diagram. In the article, a Sankey diagram has been utilized. MEFA is first stage of the plan to conduct analyses using Umberto software. The analyses performed so far will be used in the following stages of the research to assess the environmental impact using the LCA (Life Cycle Assessment) technique, to analyze costs using the LCC (Life Cycle Cost) technique, and to analyze eco-efficiency. It is important to highlight the fact that this is the first attempt of material and energy flow analysis of electricity production from UCG gas. Originality/ value This is the first approach which contains a whole chain of electricity production from Underground Coal Gasification, including stages of gas cleaning, electricity production and the additional capture of carbon dioxide.

    Opis:
    The paper presents an author’s method of eco-efficiency assessment of mining production processes in hard coal mines, which enables integrating results of evaluating both environmental and economic aspects. The proposed method uses life cycle approach to assess environmental efficiency and the result of operating activities to assess economic efficiency. The comprehensive method of assessing miningproduction processes was proposed as the Key Performance Indicator (KPI) in hard coal mines in Poland to be used to support decision making in mining companies.
    W artykule przedstawiono autorska metodę oceny ekoefektywności procesów produkcji górniczej w kopalniach węgla kamiennego, która umożliwia zintegrowanie wyników oceny aspektów środowiskowych i ekonomicznych. Proponowana metoda oceny wykorzystuje podejście cyklu życia do oceny efektywności środowiskowej oraz wynik z działalności operacyjnej do oceny efektywności ekonomicznej. Opracowaną kompleksową metodę ceny procesów produkcji górniczej zaproponowano jako kluczowy wskaźnik efektywności KPI (Key Performance Indicator) kopalń węgla kamiennego w Polsce stosowany do wspomagania procesów decyzyjnych w przedsiębiorstwach górniczych.

    Opis:
    The objective of efficient management in the public sector is first of all the rational use of limited resources that sector has. It is only possible when the performance of activities is entrusted to qualified managers specializing in the management of public sector organizations. It also depends on the implementation of modern management methods, for example procedures which enforce the efficient use of material (especially financial) resources: it is so-called management technology. Health protection and the management of public health care system units is one of the key elements of the state policy carried out as part of its constitutional duty regarding the common good. Within the system of managing these resources, territorial self-governments, particularly communal self-governments, are responsible for performing the activities which have the fundamental importance for citizens. The problem discussed in this article is first of all the clarity of planning in self-governmental independent health care centers and the availability of information on the management of public financial resources. It presents the results of research carried out in selected independent public health care centers in Warmia and Mazury region. Apart from drawing certain conclusions, the aim of the article was to propose changes in the financial management system of self-government health care units, especially planning which involves the performance budget execution system of the revenue and expenditure plan.

    Opis:
    Purpose This paper presents an algorithm developed to assess all aspects of sustainable development for hard coal mines. Additionally, an algorithm to assess the environmental efficiency and cost efficiency of mining production processes was presented. Methods To develop the computation algorithm, detailed models were proposed for environmental assessments using Life Cycle Assessment (LCA), whereas Cost-Benefit Analysis (CBA) was proposed for economic and social assessments. Results The algorithm developed is used when preparing a ranking of hard coal mines which considers the main aspects of sustainable development – environmental, economic and social. The tool also enables the performance of both environmental and cost assessment for particular unit processes of mining production. Practical implications The practical purpose is to devise an algorithm that will perform both partial and aggregated assessment of all aspects of the sustainable development of coal mines in Poland. Originality/ value It is the first method which includes all aspects of sustainable development and considers the process approach to assess coal mines.
