Opis:
The aim of the study was the analysis of three wastewater treatment plants operations (Busko Zdroj, Kazimierza Wielka and Pinczow in Swietokrzyskie voivodship). The sanitary condition of sewage sludge and the management of sludge in wastewater treatment plant were investigated. These data were made available by these wastewater treatment plants. The analyses of the sewage sludge have included the sanitary basic analysis, especially the identification of Salmonella spp. and the present of intestinal parasites eggs. It stated, that the sanitary condition of the analyzed sewage sludge was acceptable. Microbiological purity of sewage sludge and mineral composition similar to soil organic matter (humus) allows to use them as natural fertilizers, but not for the cultivation of the plants intended for human consumption. These deposits have been widely used as a material for land reclamation in Pinczow. The further aim of the research was to investigate the microbiological purity of air near the two wastewater treatment plant (Stykow and Szczecno in Swietokrzyskie voivodship). The number of colony forming units of mannitol-positive Staphylococcus sp. and the total number of mesophilic and psychrophilic bacteria were analyzed in four different distance from wastewater treatment plants. Mannitolo-positive staphylococci belong to microbiological indicators of air pollution. The number of mesophilic and psychrophilic bacteria indicate the level organic matter contamination. The air pollution was observed at all measurement points. It is known, that pathogenic microorganisms can easily pass from the water to the air and next spread in the environment. This analysis shows that the use of sewage sludge to land reclamation is helpful to preserve and restore the ecological balance of mineral elements, which is an important aspect of economic and environmental protection. It is also likely, that wastewater treatment plants may have an impact on air pollution.
Celem pracy była analiza działalności trzech oczyszczalni ścieków (Busko Zdrój, Pińczów i Kazimierza Wielka) w województwie świętokrzyskim. Materiały źródłowe zostały udostępnione dzięki uprzejmości oczyszczalni ścieków. Analizowano sposób zagospodarowania i stan sanitarny osadów ściekowych. Badania mikrobiologiczne osadu dotyczyły podstawowej analizy sanitarnej, zwłaszcza identyfikacji bakterii Salmonella spp. i jaj pasożytów jelitowych. Stwierdzono, że stan sanitarny analizowanych osadów ściekowych nie zagrażał środowisku. Mikrobiologiczna czystość osadów ściekowych i skład mineralny były zbliżone do materii organicznej gleby (humus) i pozwalały na wykorzystanie ich jako nawozów naturalnych, ale nie do uprawy roślin przeznaczonych do spożycia przez ludzi. Materiał ten był szeroko stosowany do rekultywacji gruntów w Pińczowie. Kolejnym celem pracy było określenie czystości mikrobiologicznej powietrza w pobliżu dwóch oczyszczalni ścieków (Szczecno i Styków w województwie świętokrzyskim). Określano ogólną liczbę gronkowców mannitolo-dodatnich oraz bakterii mezofilnych i psychrofilnych w czterech różnych odległościach od oczyszczalni ścieków. Mannitolo-dodatnie gronkowce należą do wskaźników mikrobiologicznego zanieczyszczenia powietrza. Liczba bakterii mezofilnych i psychrofilnych wskazuje na poziom zanieczyszczenia materią organiczną. We wszystkich punktach pomiarowych zaobserwowano zanieczyszczenie powietrza. Wiadomo, że patogenne mikroorganizmy mogą łatwo przedostawać się z cieczy do powietrza za pomocą bioareozoli. Analiza ta pokazuje, że wykorzystanie osadów ściekowych do melioracji jest pomocne do zachowania i przywrócenia równowagi ekologicznej, co jest ważnym aspektem ochrony ekonomicznej i środowiskowej. Jest również prawdopodobne, że oczyszczalnie ścieków mogą mieć niekorzystny wpływ na czystość powietrza.

Opis:
As a step towards remediation of sulphur contaminants, this study used a Crowcon Gasman (gas detection instrument) to collect and analyze Sulphuric gas samples from densely populated areas of urban Zaria. The results showed varying concentrations of Sulphur Dioxide (SO2) and Hydrogen Sulphide (H2S). The high concentrations of these pollutants detected can be attributed to increased population growth, increased production of gaseous wastes and increased number of vehicular movement. The results indicate also that the concentrations of pollutant sulphur component SO2 measured at all sampling points, with exception of the control site were hazardous while that of H2S were within safe limit set by FEPA and ACGIH respectively. Statistical tests were performed which established significant variation/relationship between detected pollutants and traffic volume. Findings from this study imply that vehicular emission within urban Zaria is not within the safe limit which further reveals that transport-related pollution in Zaria urban area can be potentially hazardous to health.

Opis:
Bridges by their nature are structures that absorb a large amount of resources. For the promoter, usually public entities, the biggest share of the investment is made when the new structures are raised. However, as will be shown in the study presented in this paper, user costs are often much higher than direct costs and may even be higher by an order of magnitude. In addition to the costs resulting from maintenance/rehabilitation interventions, there are also environmental damages due to the pollution caused by the vehicles. The presented methodology will be applied to a case study where the global costs are highlighted and determined considering the scenario in which there are no disturbances in the circulation of vehicles and when they occur due to maintenance and rehabilitation works.

Opis:
The paper addresses the sensitivity of a novel method for quantifying the environmental risks associated with the current-driven transport of adverse impacts released from offshore sources (e.g. ship traffic) with respect to the spatial resolution of the underlying hydrodynamic model. The risk is evaluated as the probability of particles released in different sea areas hitting the coast and in terms of the time after which the hit occurs (particle age) on the basis of a statistical analysis of large sets of 10-day long Lagrangian trajectories calculated for 1987–1991 for the Gulf of Finland, the Baltic Sea. The relevant 2D maps are calculated using the OAAS model with spatial resolutions of 2, 1 and 0.5 nautical miles (nm) and with identical initial, boundary and forcing conditions from the Rossby Centre 3D hydrodynamic model (RCO, Swedish Meteorological and Hydrological Institute). The spatially averaged values of the probability and particle age display hardly any dependence on the resolution. They both reach almost identical stationary levels (0.67–0.69 and ca 5.3 days respectively) after a few years of simulations. Also, the spatial distributions of the relevant fields are qualitatively similar for all resolutions. In contrast, the optimum locations for fairways depend substantially on the resolution, whereas the results for the 2 nm model differ considerably from those obtained using finer-resolutionmodels. It is concluded that eddy-permitting models with a grid step exceeding half the local baroclinic Rossby radius are suitable for a quick check of whether or not any potential gain from this method is feasible, whereas higher-resolution simulations with eddy-resolving models are necessary for detailed planning. The asymptotic values of the average probability and particle age are suggested as an indicator of the potential gain from the method in question and also as a new measure of the vulnerability of the nearshore of water bodies to offshore traffic accidents.

Opis:
The economical development of the world is based on transportation system. More than half of the products transported all over the world are carried by sea. Sea transportation is made with different kind of ships, as bulk carriers, cargo vessels, container ships, tankers. Ships are managed by people. In group or as individual, anybody can make errors. In maritime area these errors have as results accidents and disasters. Many of these events affect especially the environment. As 80% of necessary petroleum products are transported by sea, the risk of a major environment disaster caused by human errors is high. Anyway, over 99% of petroleum cargo transported by sea is carried without incidents. This paper presents the effects of human errors, mostly cases that involved tankers, which were produced in the navigation and operational processes.

Opis:
When it comes to gas turbines, their main problem concerning pollutant emissions is represented by nitric oxides. Among other emissions, sulphur oxides being much reduced due to the use of liquid distilled and gas fuels with a low content of sulphur. Using water or steam injection became the favourite method during the '80s and especially the '90s since "dry" methods and catalytic reduction were both at the beginning of the development phase. Catalytic convertors have been used since the '80s and they are still used although the costs of renewing the catalyst are very high. In the last twenty years a gradual decrease has been registered on the limits of nitric oxides from 75 ppm to 25 ppm, and now the target is oriented towards the 9 ppm level. The evolution of burning technologies of combustion makes it possible to control the level of production of nitric oxides even from the source without being necessary to use "humid" methods. This, of course, opened the market for gas turbines because they can function even in areas with limited quality water reserves, such as maritime platforms and in the desert. In this paper, we are going to show that, although water injection is still used, "dry" control technologies of burning became favourite methods for the majority of users on the industrial power generators market. The great dependency between the creation of nitric oxides and the temperature reveals the effect of direct water or steam injection on reducing nitric oxides. Recent research showed that a reduction up to 85% of nitric oxides may be obtained by using the water or steam injection all together with the improvement of aerodynamic character of the burning room.

Opis:
Nowadays the increasing number of animal enterprising depending on the needs of human population growth and nutrition need that was occurred during the production of animal breeding have revealed the manure issue. Manure from animal barn, when not stored properly, causes environmental problems including odour and visual pollution, and could create environmental pollution problems. On the other hand, random storage of manure on the land outside animal barn as a result of climate parameters such as rainfall results in leakage of manure and can cause contamination of water resources. In Turkey, animal manure obtained from animal barns is almost not utilized and is accumulated outside. Manure which is produced in animal barn to be used for agricultural purposes must be stored in the areas which prevent the spread of in the environment . Thus, the loss of minerals in the soil plant available forms are contained in manure, will be prevented. In addition, due to the nutrients and microorganisms, surface and underground water resources can be a factor in polluting and may create a risk to animal health and environmental pollution. The study has been carried out by determining the 4950 cattle breeding enterprises around the Eğirdir, Beyşehir Burdur and Salda lakes in the Lakes Region. About 50000 cattle are bred in the 4950 cattle breeding enterprises in the study area. However, of these animals 43502 are bred for commercial purposes. When the values in literature are taken into account, the daily manure amount that would be put forth has been calculated as 1500 tons. It has been concluded that animal manure which is the output of animal breeding enterprises will result in environmental pollution, water resource pollution as well as posing a threat to life in general by mixing with water resources such as underground water, lakes etc. when deposited haphazardly in stacks that are not well managed. As a result, we believe that our producers should be well informed regarding manure management prior to experiencing such problems.

Dokonano przeglądu najnowszej literatury z zakresu oddziaływania ferm trzody chlewnej i drobiu na środowisko oraz przedstawiono sposoby zagospodarowania odchodów i odpadów. Polska jest znaczącym producentem trzody chlewnej i drobiu w Europie, a produkcja drobiarska jest bardzo dynamicznie rozwijającym się działem gospodarki. Szczególnie uciążliwym źródłem zanieczyszczania środowiska są duże fermy przemysłowe2, na których hoduje się od kilku do kilkudziesięciu tysięcy zwierząt. Wynikiem intensywnej produkcji zwierząt jest wysoki poziom zanieczyszczeń emitowany do środowiska. Utrzymanie dotychczasowego tempa produkcji zapewniającego pokrycie zapotrzebowania na mięso wieprzowe i drobiowe wymaga ograniczenia negatywnego wpływu oddziaływania ferm na środowisko oraz świadomości rolników na temat sposobów zagospodarowania odchodów i odpadów z ferm trzody chlewnej i drobiu.
The article reviews latest literature on the impact of pig and poultry farms on the environment and presents ways of managing excrements and wastes from such farms. Poland is a leading producer of pigs and poultry in Europe with poultry production remaining a dynamically developing sector of the economy. Large factory farms with Integrated Pollution Prevention and Control (IPPC), which house from several to tens of thousands animals are particularly troublesome sources of environmental pollution. An outcome of intensive animal production is the high level of pollution effected upon the environment. Retention of the current rate of production to satisfy demands for pork and poultry does not only require the reduction of the negative impacts of such farms on the environment, but also the increased awareness of farmers on ways of managing excrements and wastes from hog and poultry farms.

Opis:
Anthropogenic activities often result in the introduction of noxious contaminants into the environment with resultant distribution and transfer across the food chain. This study reports on the level of trace metals (Cd, Pb, Cu and Zn) in African foxtail (Cenchrus ciliaris) plant; widely referred to as “common grass” and possible implication across the food chain. Plant samples were collected from stratified study area, processed and analysed using validated acid leaching protocols. Instrumental analysis of the metallic content was by ICP-OES. Quality assurance of the analytical protocol revealed its’ applicability to the environmental samples through metallic recoveries (n=3) in the range of 85.6 – 91 %. The overall mean concentration of analysed metals in samples ranged from 9.34 mg/kg – 38.6 mg/kg; 64.2 mg/kg – 105.2 mg/kg; 0.28 mg/kg – 0.73 mg/kg and 0.54 mg/kg – 16.3 mg/kg for Cu, Zn, Cd and Pb respectively across SCP1-SCP4. Incremental order of analysed trace metals across the SCPs were Cu: SCP1>SCP2>SCP3>SCP4; Zn: SCP1>SCP2>SCP3> SCP4; Cd: SCP1>SCP2>SCP3 = SCP4 and Pb: SCP1>SCP2> SCP3>SCP4. Strong correlation (r > 0.99) was obtained between all the analysed trace metals. Significant difference at (p < 0.05) was found between the analysed metals and SCP 1 while those between the metals and SCPs 2- 4 were non-significant. Accumulation of these metals in ruminants and transfer across the food chain is most probable.

Opis:
The article discusses the issues of values and social responsibility of universities. On the one hand, the foundations of functioning of universities, which are created by research and education and the role of universities in formation, are recalled.  On the other hand, it was reminded that the heart of universities, their DNA, are academic values, defined primarily in the Magna Charta Universitatum, but also in many other documents, such as the Code of Values of the Jagiellonian University. Hence, universities are increasingly often referred to not only as universities of knowledge, but also as universities of wisdom. Together, they are the basis for the social responsibility of universities.  However, they alone are not enough for this social responsibility to materialise.  Appropriate behaviour and actions are essential.  Because knowledge alone is not everything.  Such actions are always necessary, but especially when we find ourselves, as a country, humanity and a planet, in a crisis situation related to the climate disaster, which we are already partially experiencing. After the presentation of the most important current facts related to the climate and environmental crisis, the tasks to be undertaken urgently in this context by universities were presented, from broadly understood education, through convincing politicians to ambitious and quick actions, to intensive work on innovative solutions that can contribute to reducing threats brought by the climate and environmental crisis, pointing out, among others, the initiatives proposed by the newly created network of universities U7.

The main task for natural marine environment protection is to prevent the inflow of various contaminants including oil substances and the real challenge is the ability to rapidly detect these pollutants. Moreover important is to find the source or the maker of the oil spill. In this paper, we consider fundamental physical aspects in the area of possibility of monitoring the natural marine ecosystem based on fluorescence spectroscopy. We utilize the fluorescence ability of numerous oil components – mainly polycyclic hydrocarbons. The paper concerns the spectrofluorimetric characterization of oils have been in use during exploitation of the marine fleet, i.e. lubricate oil, fuels, transformer and hydraulic oils as well as crude oils or their residues. Every kind of oil has a chance to enter the marine environment, especially in a case of ship emergency or after collision with other vessel ore shoreline structure as well as when ship enters the stranding. After discharge of oil, some of oil components are dissolved in the water, bacteria or photochemical reactions, which results in transformation of composition of oil, degrade some. Fluorescence spectrometer Perkin Elmer LS55 was applied to obtain the fluorescence spectra using different excitation wavelength in the range from 240 nm to 500 nm. We discuss the changes of the shapes of excitationemission spectra (EEMs) of various types of oil and the EEMs spectra after contact of oil with seawater as an oil-inwater emulsion, which is the most frequent form of oil in the water column. Significant changes in the shape of spectra and displacement of the peaks are observed.

Artykuł ma na celu przybliżenie tematyki badań prowadzonych obecnie nad zagrożeniami wynikającymi z zanieczyszczenia powietrza pyłem wnikającym do budynków w środowisku miejskim. Dokonano przeglądu przepisów światowych, europejskich i krajowych regulujących dopuszczalne normy zanieczyszczenia powietrza pyłami, a także przeglądu aktualnych badań jakości powietrza (zewnętrznego i wewnętrznego) realizowanych w Polsce i na świecie. Omawiając rozpoczęte prace nad opracowaniem monitoringu zanieczyszczenia pyłem powietrza we wnętrzach w budynkach, wskazano na złożoność problematyki naukowej, związanej ze zmiennym poziomem stężenia pyłów we wnętrzach, związaną np. z aktywnością mieszkańców. Jednocześnie wskazano na potrzebę uwzględnienia w planach badań nad jakością powietrza wewnętrznego (IAQ) stężenia pyłu jako elementu jakości powietrza, ze względu na światowy trend wprowadzania tych zanieczyszczeń do sieciowych wskaźników jakości powietrza (np. do internetowej sieci AQI – Air Quality Index).
