Opis:
Road schemes are linear in nature, which makes the investment process exceptionally difficult and complex, requiring the involvement of large human potential, time-consuming and very expensive. One road investment is subject to numerous consultations, requires many different studies, collecting a huge amount of opinions as well as approvals and obtaining a number of decisions. Currently without including in the project some solutions that would both guarantee minimal influence of the investment on the environment and ensure the efficiency of local ecosystems it is impossible to obtain the positive decision concerning the condition of the environment, which would allow the realisation of the project. An engineer of the 21st century apart from providing the right construction of a given structure, which ensures that this structure is secure, functional, resistant and has architectural merit, must also take into consideration local environmental conditions. The engineer has to ensure that the environment may function without any obstacles and the species may migrate without restraint. To do this, an engineer needs to have clear guidelines concerning both the project and its realisation. The article contains the general form of these guidelines.

Opis:
Greater and greater number of cargo ships sailing over small, restricted water areas can endanger the environment - in the case of disaster - by spilling fuel oil, carried in the ship’s bottom tanks for its propulsion. In this paper is proposed an alternative solution (against that of double plating) in the form of the second, elastic protective barrier which would be able to decrease risk of spilling in the case of loss of ship’s plating tightness due to collision or grounding.

Opis:
Small closed sea shipping regions (such as the Baltic Sea) are specially vulnerable to consequences of ecological disasters due to spills of fuel oil used for ship propulsion and carried in single-plating double-bottom tanks. An alternative solution (against the recommended double- plating structure) was proposed. It consists in applying the second, elastic protection barrier to decrease risk of oil spills resulting from loss of tightness of ship plating in consequence of e.g. collision or grounding.

Opis:
Oils can be optically described by two parameters: light absorption coefficient and light refraction coefficient. Spectrum of absorption coefficient manifests itself in colour of oil, whereas spectrum of refraction coefficient impacts on both refractive and reflective properties of interface between oil and surroundings. Both spectra of absorption coefficient and refraction coefficient have distinctive slopes in ultraviolet edge of spectrum where values of mentioned coefficients decrease from extremely high in ultraviolet to relatively low in visual range. Possibility of perceiving of oil existing in the form of thin film or in the form of an emulsion depends on ambient light conditions and on mentioned optical properties. Additionally perceiving of oil depends on thickness of the oil film and on type of substrate on which oil is spread (water, metal etc.), as well as - if emulsion oil-in-water or water-in-oil is considered - on the droplets size distribution. The present paper begins with a review of optical properties of several oils. Next, an impact of changes of those properties on optical properties of an oil film (spread on water) as well as an impact of those properties on optical properties of oil-in-water emulsion is explained. Finally, exemplary results of numerical simulation of light transfer in marine environment (using above optical properties) - e.g. angular distributions of optical contrast of both sea areas clean and polluted by an oil-film are presented.

Opis:
The paper concerns a propulsion system of merchant ships intended for sailing in the Baltic Sea zone. Such system is to satisfy the ecological requirements determined by relevant international conventions for special zones to which the Baltic Sea also belongs. The paper draws attention to gas turbine used as a prime mover for such ships, because it satisfies the ecological requirements and has also other advantages. Application of gas turbine for ship powering does not require exhaust gas to be purified, however it requires fuel oils of a low sulphur content to be used. If the ecological rules impose the using of the fuel oils of similar quality for diesel engines then gas turbine propulsion system will be comparable - also economically (regarding specific fuel oil consumption cost) - with that of diesel engine. It would be even more favourable in a combine gas turbine /steam turbine system, especially at compound production of electric and heat energy (i.e. COGES systems). In the Baltic Sea zone gas turbines willfind application to powering a. o. such ships as : fast car-passenger ferries, fast cargo ships, special vehicles (hydrofoils, hovercraft, motor yachts).

Opis:
In the paper a probabilistic model of environmental risk of ship power plant is presented. This is a linear strategy model with an additional restraint. It can be usedfor assessing risk to marine environment, which results from ship power plant operation. The risk is a sum of component probabilities of exceedance of the limits assigned - by MARPOL convention to particular kinds of pollution discharged from ships, multiplied by weight factors. The factors determine a degree of harmfulness of a discharge for the environment. The restraint concerns the case of exceedance of the limits assumed unacceptable by the convention. A risk value is be contained within (0,1) interval. Moreover a criterion for environmental safety of ship power plant was propsed. This is the criterion of the ALARP class, in which an intolerable risk level and acceptable one is distinguished. Suggestions concerning determination of the levels are submitted. The considerations are illustrated by results of example computer investigations of influence of reliability oftechnical elements of the systems responsible for environmental safety of a hypothetical ship power plant on environmental risk value. Three qualification levels of ship:s. crew were accounted for: high, average and low.

Opis:
The balance of wastes originating from the foundry processes of ferrous alloys, prepared on the basis of data made available by the Polish Central Statistical Office, is presented in this paper. The kind and amount of individual foundry wastes subjected to management and storage by foundry plants were analysed. The problem of wastes between the years 2010–2016 is discussed on the national scale, as well as in individual regions or voivodeships. Altogether, 27,375.9 tons of waste from the group no. 10, of which non-ferrous metal and ferrous alloy wastes from foundry plants constituted 2%, were produced in Poland in 2010. This situation remained at a similar level over successive years, till 2014. The positive prognosis constitutes the fact that the amount of waste stored on dumping grounds belonging to foundry plants in Poland is gradually decreasing. This may be related to increasing costs of waste storage. During the tested years, the annual amount of gathered waste decreased from 4,796.6 thousand tons (in 2010) to 4,477.6 thousand tons (in 2014).

Opis:
Subject and purpose of work: The article presents research aimed at creating the ranking of provinces due to the degree of environmental pollution. The presentation of the spatial distribution of pollutants should result in taking appropriate pro-ecological actions in the provinces. Materials and methods: Secondary material included in the research was the publication entitled “Environmental Protection – Environment 2017” by the Central Statistical Office. The method of ranking diagnostic variables was applied and then a synthetic variable determining the level of pollution in individual provinces was constructed, which made it possible to create their ranking. In the final stage, the author’s own method was implemented in order to divide the provinces into 3 groups. Results: The provinces were ranked from a relatively little to very polluted ones. Three groups of provinces were distinguished according to the criterion discussed. It has been revealed that the third group with the highest degree of environmental contamination includes as many as 8 provinces, that is half of them. Conclusions: The author believes that in order to prepare a more precise spatial diagnosis of the state of the natural environment in Poland, research has to be extended by including adequate information at the county level.
Przedmiot i cel pracy: W artykule przedstawiono badania mające na celu budowę rankingu województw ze względu na stopień zanieczyszczenia środowiska. Ukazanie przestrzennego rozkładu zanieczyszczeń skutkować winno podjęciem właściwych działań proekologicznych w przestrzeni województw. Materiały i metody: W badaniach wykorzystano materiały wtórne zamieszczone w wydawnictwie GUS „Ochrona Środowiska – Environment 2017”. Zastosowano metodę rangowania zmiennych diagnostycznych, a następnie skonstruowano zmienną syntetyczną określającą poziom zanieczyszczeń w poszczególnych województwach, co pozwoliło na budowę ich rankingu. W końcowym etapie wykorzystując metodę własną, dokonano podziału województw na 3 grupy. Wyniki: Ranking zawiera uporządkowane województwa od stosunkowo mało do bardzo zanieczyszczonych. Wyodrębniono 3 grupy województw ze względu na omawiane kryterium. Okazuje się, że do grupy III o najwyższym stopniu skażenia środowiska należy aż 8 województw, co stanowi połowę ich liczebności. Wnioski: Autor uważa, iż celem sporządzenia bardziej precyzyjnej przestrzennie diagnozy w zakresie stanu środowiska naturalnego w Polsce należy rozszerzyć badania poprzez uwzględnienie adekwatnych informacji na poziomie powiatów.

Opis:
The project "CERGOP-2, a multipurpose and interdisciplinary sensor array for environmental research in Central Europe" was approved by EC within the 5th Framework Program and started ApriI 1st, 2003. It was officially terminated October 31, 2006 (amendment 3 and 4) and financially closed end of 2007. The results of 17 work packages were published in the Reports of Geodesy, Warsaw University of Technology, Poland comprising altogether more than 3600 pages. On behalf of 14 contractors I give a summary of the current results which concern, for the area of investigation (15 % of Europe), a high quality GPS network operational for the next decade, velocity field and strain maps for geodynamical investigations and hazard mitigation, data for climate research and weather forecast, data for real time navigation and a seamless data bank for scientific and public access. The results are based on partly continuous GPS measurements at up to 80 permanent stations carried out during the last 14 years. In addition, I try to give a future perspective for the investigations to be done during the next decades which aim at the understanding of the internal forces being the reason for plate kinematics which formed the present shape of the earth surface during the last billion of years. Hopefully next generations will be able to forecast sudden changes of the earth surface including the necessary energy transfer leading to earth quakes and to give valuable support for risk management and mitigation procedures.

In the paper an attempt of assessment of equipment with some appliances and facilities of environmental protection in villages was made. The analysis was conducted taking into account division of country territory into voivodeships using methods of multi- -dimensional comparative analysis. The final result of the study is voivodeships ranking and dividing voivodeships into three groups: of a high, average and low level of village environmentally friendly infrastructure. Attention was paid to relatively great span between the first group (group of the best equipment) and the third group – the worst in this respect.
Celem artykułu jest ukazanie aktualnego stanu wyposażenia wsi w infrastrukturę proekologiczną. Zebrane informacje sprowadzono do stanu porównywalności, stosując metodę unitaryzacji zerowanej. Unormowane zmienne pozwoliły otrzymać wartości zmiennej syntetycznej charakteryzujące każdy obiekt (województwo). Zmienne te są podstawą budowy rankingu województw przedstawiającego aktualną sytuację w zakresie przestrzennych zróżnicowań wyposażenia wsi w obiekty i urządzenia sprzyjające środowisku. Końcowym etapem badań jest podział obiektów na trzy grupy województwa: o wysokim, przeciętnym i niskim poziomie proekologicznego wyposażenia wsi.

The study is supposed to start a series of research on the role of natural building as an environment friendly solution. It includes the results of a survey which was carried out to define the level of university students’ ecological awareness of benefits and development prospects of this technology in Poland. Young people were surveyed to find out their knowledge of the solutions based on natural resources available in the environment. It has been established whether positive attitude of students toward the natural environment can find reflection in their approval of eco-building and subsequently, willingness to invest money in construction of such buildings in the future. An important question has been addressed, that is, whether people are interested in houses made of clay, straw or wood an whether they consider them as cheap, durable, modern and esthetic architectural forms.

Opis:
Nowadays, there is a noticeable trend aimed at ensuring broad protection of the natural environment – both for the sake of preserving biodiversity and the quality of life of the future generations. However, the related activities of public authorities and private entities often involve limiting the rights of property owners. The Polish Constitutional Tribunal has ruled on the conflict between property rights and conservation of nature. The Tribunal has pointed out that the principles of sustainable development require an appropriate balance between environment protection on one hand and social and civilizational development on the other. In accordance with the previous jurisprudence of the Tribunal, the article will present the limits set for the state's environment policy in certain specific areas by the Constitution. It is acceptable to establish mechanisms to control the exploitation of plantings belonging to real property. Property owners may be required to obtain permits for their removal, and in the absence of such permits, they may be punished with forfeiture of timber or a fine. However, it is incompatible with the principle of proportionality and infringes the right of owners by arbitrary restrictions or imposed automatically sanctions, without the possibility of taking into account the circumstances. Moreover, the Tribunal has pointed out that the Constitution does not allow disproportionate narrowing down of the possibility to seek compensation for restrictions in the use of real property for the sake of environment protection. Only the two-year deadline for submitting claims in this respect has been considered too painful – too short and impossible to be reinstated for justified reasons.
