Opis:
Spalanie odpadów wiąże się z nieuniknioną emisją zanieczyszczeń do atmosfery, a tym samym negatywnym oddziaływaniem na jakość powietrza. Skala tego oddziaływania jest jednak często wyolbrzymiana. W pracy przedstawiono wyniki obliczeń rozprzestrzeniania się zanieczyszczeń w atmosferze przeprowadzonych dla jednej z największych spalarni odpadów przemysłowych funkcjonujących w Polsce (o zdolności przerobowej 3 tony na godzinę), w której w znacznych ilościach przekształcane są termicznie odpady niebezpieczne. Wyniki te potwierdzają fakt, że spalarnia spełniająca wymogi najlepszych dostępnych technik (BAT), określone dla spalania odpadów niebezpiecznych, w małym stopniu wpływa na zanieczyszczenie powietrza. Jest to głównie efektem wysokiej skuteczności oczyszczania gazów odlotowych i występowania emisji substancji zanieczyszczających na bardzo niskim poziomie (dużo poniżej obowiązujących standardów emisyjnych).
Waste incineration causes unavoidable pollutant emissions to atmosphere and thus negative impact on air quality, but scale of the influence is often exaggerated. In the paper computation results of the atmospheric dispersion of pollutants were presented for one of the largest industrial waste incineration plant existing in Poland (incinerator capacity: 3 ton per hour) where hazardous wastes are thermal treated in significant amount. The results confirm the fact that the waste incineration plant meeting best available techniques (BAT) requirements determined for hazardous waste incineration influence on air quality to a small extent. This effect is caused mainly by high efficiency of the flue gas treatment and very low air pollutant emissions (far less then the forced emission limits).

Opis:
Research background: The heterogeneity in the factors that affect demand for environmental quality implicates a diverse set of policies and actions aimed at achieving cleaner production to address the challenges posed by pollution and damage to the natural environment. Even though this topic has been widely addressed, mainly from the traditional perspective of the Environmental Kuznets Curves hypothesis (EKC), it has been assumed that the environment is a luxury good with an income elasticity greater than unity. However, it has recently been recognized that the relationship between income and demand for cleaner energy may be more complex and that further inquiry may be needed for a better understanding. Purpose of the article: This research work, employing a panel of European countries, offers direct explicit parameters for the elasticity of income-environmental quality demand for Greenhouse Gases (GHG), as well as its relationship with other important factors. It provides quantitative novel insights into the complex relationship between income and the preferences for cleaner energy. Methods: A hierarchical regression equations approach is used to analyze the evolution of the elasticity of income-environmental quality demand with the inclusion of further co-variates that are relevant for the preferences side of the EKC, such as consumption, R+D investment and BERD (Business Enterprise Research and Development). The data for the empirical study comes from a panel of 16 European countries for the period from 2010 to 2020. Findings & value added: The results show robust evidence that the elasticity of environmental quality demand, which although positive and significant, does not exceed one. To obtain an elasticity above unity, two more variables are needed, namely the R+D expenditure of business enterprises and the exposure of citizens to air pollution. These two factors have a similar or even higher effect on the preferences of agents for cleaner energy, which also means that the preferences of the citizens are endogenous to technological development. At the theoretical level, this work shows that the technological and preferences arguments are not substitute explanations of the EKC, but that technological development exerts a positive effect on the preferences of inhabitants, whose demand for environmental quality is heavily conditioned by their capabilities to see pollution, even more than by their income level. This also means that public policies directed to improve environmental awareness should be directed first towards those regions where the exposure of the citizens to pollution is lower.

Opis:
Tests have been carried out to evaluate the performance, emissions and heat release characteristics of a double cylinder direct injection diesel engine fuelled with tyre pyrolysis oil and diesel oil. The combustion parameters such as heat release rate, cylinder peak pressure, maximum rate of cylinder pressure, combustion knocking were also analysed. For purposes of this work raw pyrolysis oil was derived from waste vehicle tyres through vacuum pyrolysis realized in experimental installation. Results showed that the brake thermal efficiency of the engine fuelled with pyrolysis oil increased. THC, CO and CO2 emissions were found to be higher due to high aromatic content and longer ignition delay, whereas NOx shows increasing tendency due to greater heat release rate. The cylinder peak pressure did not change. The ignition delay became greater what can be the reason of problems with combustion knocking. Pyrolysis oil has a mass fraction of individual elements similar to diesel fuel but the chemical composition of hydrocarbons included in these fuels is different. The product of pyrolysis contains too much soot, sulphur, light and heavy hydrocarbons fractions for direct using it in engine. Aromatics content gives this fuel a distinctive smell. Pyrolysis oil is toxic and dangerous in use due to the polycyclic aromatic hydrocarbons (PAH). However raw pyrolysis oil is not suitable to use it as a CI fuel and requires additional distillation before using it in diesel engines as an alternative fuel in the future.

Opis:
The study aims to analyze the measurement data of PM10 particulate matter in the Krakow agglomeration. It develops a model of the backward trajectory of air masses to determine whether and to what extent natural phenomena, such as forest fires outside Poland, affect the level of air pollution. The article describes the process of pollutant dispersion in the Earth’s atmosphere and the principles of air monitoring in the Krakow agglomeration. The study uses 2022 measurement data from ten monitoring stations of the Chief Inspectorate of Environmental Protection in the Krakow agglomeration. Two periods of increased PM10 particulate matter were selected. On the basis of the HYSPLIT software, which uses backward air trajectories, the influx of transboundary pollution was simulated. Then, by analyzing the FIRMS fire information system, an attempt was made to document that the pollution sources considered were of natural origin and that human activity did not in any way determine the emissions and their magnitude.
Celem badań była analiza danych pomiarowych pyłów zawieszonych PM10 na terenie aglomeracji krakowskiej oraz wykonanie modelu trajektorii wstecznych mas powietrza w celu określenia, czy i w jakim stopniu zjawiska naturalne, takie jak pożary lasów poza granicami Polski, wpływają na stopień zanieczyszczenia powietrza. W artykule opisano proces dyspersji zanieczyszczeń w atmosferze ziemskiej oraz zasady monitoringu powietrza w aglomeracji krakowskiej. Do opracowania posłużono się danymi pomiarowymi z 2022 r. z dziesięciu stacji monitoringu Głównego Inspektoratu Ochrony Środowiska, znajdujących się na terenie aglomeracji krakowskiej, gdzie wytypowano dwa epizody zwiększonego stopnia zanieczyszczenia pyłami zawieszonymi PM10. Bazując na oprogramowaniu HYSPLIT, który wykorzystuje wsteczne trajektorie powietrza, przeprowadzono symulację napływu zanieczyszczeń transgranicznych. Następnie analizując system informacji o pożarach FIRMS, podjęto się próby udokumentowania, iż uwzględnione źródła zanieczyszczeń miały pochodzenie naturalne, a działalność człowieka w żaden sposób nie decydowała o emisji i jej wielkości.

This paper aims to determine under what conditions an airport operator could be held liable for noise pollution. The author reviews the general notions of noise pollution and airport liability and discusses how these two elements interconnect using case-law examples from the US, Germany and Poland. The main conclusion of these deliberations is that airport liability for noise pollution is not only dependent on domestic law but also the country’s attitude towards the issue at hand, including how it perceives the values of economic development of air transport and human well-being.
Celem artykułu jest ustalenie, na jakich warunkach operator lotniska może zostać pociągnięty do odpowiedzialności cywilnej za zanieczyszczenie hałasem. Autorka omawia ogólne pojęcia zanieczyszczenia hałasem oraz odpowiedzialności operatora lotniska oraz bada jak te dwa zjawiska wzajemnie na siebie oddziałują, posługując się orzecznictwem ze Stanów Zjednoczonych, Niemiec oraz Polski. Głównym wnioskiem rozważań jest obserwacja, iż odpowiedzialność operatora lotniska za zanieczyszczenie dźwiękiem zależy nie tylko od prawa krajowego, ale także od indywidualnego podejścia danego kraju, do m.in. rozwoju ekonomicznego transportu lotniczego oraz dobrostanu człowieka.

Opis:
This paper seeks to highlight the impact of the increasing container throughput in northern Adriatic ports on air quality. A comparative analysis of air quality is given, which consist of certain environmental parameters at selected measuring stations near the container terminals of the northern Adriatic ports Rijeka, Trieste, Koper, and Venice. The parameters were analyzed based on a limited amount of air quality monitoring data for the port areas. As the port transport sector increases pollutant emissions, the results of these analyzes can also be used to take appropriate measures to reduce these particulate matter emissions. The aim of this paper is to determine the impact of increasing the container throughput within the ports of the northern Adriatic Sea on air quality, based on certain environmental parameters related to the shipping or delivery of containers by road. The results of the research, based on available data, have shown that the increase in container throughput of the northern Adriatic ports has not decreased the air quality of urban areas of the respective port cities. The air quality value of the northern Adriatic ports is substantially below the limits set by the EU Air Quality Directive (2008/50), thus it does not affect the health of the inhabitants of the analyzed cities.

Opis:
ObjectivesAir pollution has become a critical environmental issue, which severely threatens the well-being of asthma patients. The quality of life of these patients, when exposed to air pollutants such as particulate matter 10 (PM10), has been poorly studied. The current research examined the association between the concentration of PM10 in the air and the quality of life of patients with asthma.Material and MethodsThe study group consisted of 300 adult asthma patients treated in 2 allergy outpatient clinics in Kraków, who declared they would not leave the city in the 14-day study period. Daily concentrations of PM10 from air monitoring stations were recorded over a period of 2 weeks, following which the patients filled out the standardized Asthma Quality of Life Questionnaire (AQLQ) regarding the monitored period to assess the total quality of life and its 4 domains (symptoms, limitation of activity, emotional functioning and environmental stimuli).ResultsThe average PM10 exposure was 65.2 μg/m3 and only 30% of the patients were exposed to values of ≤50 μg/m3, i.e., the highest 24-h threshold value considered acceptable by the World Health Organization. The observed effect of an increased level of exposure to airborne PM10 was associated with reduced scores in AQLQ from 0.40 at the medium level to 0.46 at the high level, in comparison to the low level. The total score of the asthma-related quality of life and its domains showed poorer outcomes as the concentration of PM10 was increasing (every 0.08 pt per a 10 μg/m3 increase).ConclusionsThe increase in the concentration of PM10 in the air impacts on the overall quality of life and its particular domains in people with exceptional predispositions, such as patients with bronchial asthma. Physicians taking care of asthma patients should pay special attention to the quality of patient’s life in response to the course and control of that illness, in relation to air pollution.

Opis:
Rapeseed oil in a few applications can be used as an engine fuel. Although it has worse properties than its methyl esters, it can be considered as an alternative fuel in engines adapted to its use. The article describes some problems resulting from the use of pure rapeseed oil as a fuel for compression ignition internal combustion engines. Differences between basic physical and chemical properties between diesel oil and rapeseed oil will be discussed and their impact on the theoretical engine performance and emission of pollutants from the exhaust system, with a focus on viscosity of rapeseed oil and the impact of this parameter on the fuel injection process. The basic changes in the engine design to be able to run on the rapeseed oil are discussed. The results of author’s own tests of the engine adapted to operate on the rapeseed oil and its blends with diesel oil carried out on the engine dynamometer test bench are presented. The theoretical assumptions presented in the Introduction were tested experimentally in the dynamometric test. Combination of higher density of rapeseed oil and its smaller stoichiometric value caused by the presence of oxygen and a smaller share of hydrogen in the fuel, means that a larger mass of fuel can be injected into the charge compressed into the cylinder. Thanks to this, the engine powered by rapeseed oil and diesel oil can reach similar powers.

Celem opracowania jest zbadanie wpływu ekspansywnej polityki fiskalnej, polegającej na ogólnym zwiększaniu wydatków rządowych, na stan środowiska przyrodniczego, a konkretnie — zanieczyszczenie powietrza. Analizę przeprowadzono na podstawie modelu realnego cyklu koniunkturalnego (RBC). Wyniki symulacji wskazują, że ekspansywna polityka fiskalna, przyczyniając się do wzrostu PKB, powoduje jednocześnie pogorszenie się jakości powietrza. Z analizy wynika również, że w dłuższym okresie głównym mechanizmem, poprzez który polityka ta wpływa na poziom emisji zanieczyszczeń, jest akumulacja kapitału publicznego. W celu zminimalizowania negatywnych skutków ekspansji fiskalnej dla środowiska szczególnie istotne jest zatem, by inwestycje publiczne miały charakter proekologiczny.
The aim of the article is to analyse the impact of expansionary fiscal policy, involving an overall increase in government expenditure, on the condition of the natural environment and, more specifically, on air pollution. The analysis is based on the Real Business Cycle (RBC) model. The results of the simulations indicate that expansionary fiscal policy, contributing to GDP growth, also results in deterioration of air quality. The analysis also shows that in the longer term, the main mechanism by which this policy affects the level of air pollution emission is the accumulation of public capital. Therefore, in order to minimise the negative effects of fiscal expansion on the environment, it is particularly important to invest in pro-ecological public investments.

Opis:
Exhaust gas emissions from ships are increasingly polluting the air environment seriously. Therefore, the MARPOL 73/78 Annex VI is applied for all ships from 2017, Annex VI provided that the concentrations of NOx,SOx CO contained in ship’s exhaust gases must be less than 6.4 g/kWh, 0.6 g/kWh, and 5.5g/kWh respectively. Today, there are many solutions to reduce pollution emissions from exhaust gas of ships, such as improving combustion, using oil emulsion, using biofuel,…However, these solutions also have a handful of disadventages such as being unable to thoroughly resoulve problems, high cost, and very difficult to improve the quality of ship exhaust gas emissions for old ships. Exhaust gas treatment method uses a centralized treatment system where exhaust gas from the thermal engines is taken in a centralized treatment system before discharging into the air. After centralized treatment system, in comparision with raw exhaust gas, soot can be reduced by 98%, NOx can be reduced by 75%, SOx can be reduced by 80%. This method of treatment is not only low cost, good quality but also make marine heat-engines still use traditional fuels as well as need not improve its structure.

Opis:
The combustion of fuels is and will be in the nearest future a basic way of acquiring the energy, among others, for transport purposes. Transport causes many threats for natural environment. It produces powders and particulates, together with many gaseous noxious substances and is also the source of noise and vibrations. Sources of propulsion, applied in transport, are almost exclusively piston-combustion engines, among which the dominant role play self-ignition engines. In the light of well-known advantages of these engines, they were accepted as most beneficial sources of car vehicles' propulsion in nearest decades, provided they meet the requirements of the future legal regulations regarding the environmental protection. The emission of nitrogen oxides (NOx) and particulate matters (PM) is a problem to be solved in modern engines. This constitutes so called targets conflict, consisting in excluding the alternative of both coefficients’ decrease, in the way of regulation the set of an engine and the limiting emissions, permitted by the EURO regulations. From among many different methods of limiting both the formation and emission of NOx, the method of the selective catalytic reduction (SCR) is universally applied. This method requires special installation with the catalyst and the reservoir intended for the "clinically" clean reductive measure. In the aspect of constituting opinions regarding the need of reducing additional installations and media on board the vehicle, it seems that to supply the engine with fuel-water emulsion and especially fuel-water microemulsion becomes an interesting solution.
