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:: The PBN ICAO program implemented in the global scale is determining changes in managing the airspace, contributing to the increase in the elasticity and the bandwidth in the global air traffic. However it requires the right infrastructure, proper legal changes but in exchange it offers specific economical – financial benefits. The implementation of the PBN ICAO program in the global scale it is also a profit in reducing the environmental decay caused by aviation.

Opis:: Article analyses issues connected with lack of specific regulations regarding performance of examinations by accredited laboratories in the process of remediation and possibilities for authorities to verify results of such examinations. In order to provide contest for the analysis, the article familiarizes the reader with short description of the remediation as a legal institution as well as the corresponding procedure. Article also includes de lege ferenda postulates in this respect.

Opis:: The aim of this work was to estimate mobility of pollutants contained in ashsludge granulates, expressed by their possibilities of elution by water and by estimating their potential danger to the environment. Materials used in experimental research (one stage leaching tests) was ash-sludge granulates made of two different kinds of waste: fly ashes from brown coal (30%) from 'Bełchatów' Powerplant and communal sewage sludge (70%) from municipal sewage treatment plant in Zabrze (southern Poland). However sewage sludge are an alternative to organic fertilizers (e.g. manure) and nitrogen and phosphorus content is relatively high but potassium concentrations are much less. Tested sewage sludge were modified by various potassium salts, which would improve their fertilizing abilities because potassium is easy-leaching element during sewage treatment. In first part of sewages KCl and in second K2SO4 were used both in load 344 g/kg d.m. Blank tests were carried on unmodified material. One stage leaching test were carried and equilibrium was reached after 24 hours. Water extracts (eluates) were analyzed for presence of nitrogen group compounds, phosphorus, chlorides, sulphates, magnesium, calcium and heavy metals. Also loads of particular compounds were calculated. On the basis of research (leaching test) there has been calculated a load of the pollution that were being washed out in mg/kg dry mass of used granulates. Eluates obtained in one-stage leaching tests had alkaline pH and high EC value which rise with potassium concentrations. In eluates from tested materials some parameters (e.g. ammonium, nitrites, COD, sulphates and potassium) exceed polish limits for sewages discharged to waters and grounds. Especially high were chlorides concentrations (10 times to high) due to KCl content. The highest heavy metals concentrations were observed in eluates from granulates modified by K2SO4 due to lower pH value in comparison to unmodified material. In next step in this researches will be to find optimal balance between fly ash and sewage sludge and use compounds for pH corrections.

Opis:: This paper aims to analyse the scope of constitutional reform no. 1/2022, approved last 8th February by the Italian Parliament, with which the Articles 9 and 41 of the Constitution have been modified. Thanks to this amendment, the environment (the ecosystem and biodiversity) has been included as a legal asset subject that needs an expressed protection. Specifically, it is possible to highlight the critical profiles concerning the balance that the legislator has already intended to offer at a regulatory level between respect for the environment and private economic activities. In this field, the Ilva case-law represents a milestone for the Constitutional Court and the Italian legislator.

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.
