Abstract The article presents the role and importance of creating new green areas in the areas of urban agglomerations. Particular attention was paid to the processes of creating new green areas in post-industrial areas and urban wastelands and their restoration for cities. The issue of the formation of pocket parks is raised and the results of the detailed research carried out by the authors in 2020 are briefly discussed. The article presents a comparative analysis of several selected examples of pocket parks, describes the role they play in cities. The purpose of the research was to determine what elements of pocket parks play an important role for the microclimate of cities and their communities. An example of the creation of a new pocket park in the city center of Gliwice, Poland is presented. The conclusions of the research and the evaluation of the experiment carried out by the authors can be useful for the creation of urban policies, planning of green areas in cities and the creation of utility-functional programs for new green areas.

Abstract Due to the difficulties in implementing other methods of removing organic compounds and nitrogen from wastewater, municipal wastewater treatment plants use classical processes (nitrification and denitrification) that require large energy expenditure on aeration. The problem of high energy consumption concerns every treatment plant using aerobic activated sludge, hence the constant attempts to introduce possibly intelligent aeration control techniques. In this study, a short-term (hourly) forecast of oxygen concentration in the aeration chamber was calculated under the conditions of changing values of wastewater flow and pollutant concentrations as well as active aeration control according to an unchanging algorithm. Artificial neural networks were used to calculate the forecast. It is shown that an accurate prediction can be obtained by using different sets of input data but depending on what data we choose, the neural network required to obtain a good result has a more or less complex structure. The resulting prediction can be applied as part of a system for detecting abnormal situations and for preventing excessive energy consumption through unnecessary over-oxygenation of activated sludge.

Abstract The Global Environmental Monitoring Index (GEMI) represents a vegetation index that allows for making analysis. The index is not that sensitive to atmospheric effects. GEMI has been applied for the investigation of disruptions in the coniferous forests in Pernik Province, which is situated in the western parts of Bulgaria. The basic data comes from Landsat 8 and Corine Land Cover. The results of the study show that the index performs well in the distinguishment of broad-leaved vegetation from the coniferous one. At the same time the index doesn’t always provide satisfying results when it comes to deforestation. In conclusion GEMI provides good results, yet it’s use should be controlled and supported by other vegetation indices.
全球环境监测指数(GEMI)是一种植被指数，可以进行分析。该指数对大气影响不那么敏感。GEMI已被申请用于调查位于保加利亚西部的佩尼克省针叶林的破坏情况。基本数据来自Landsat 8和Corine Land Cover。研究结果表明，该指数能较好地区分阔叶植被和针叶林植被。与此同时，当涉及到森林砍伐时，该指数并不总是提供令人满意的结果。综上所示，GEMI的使用效果较好，但需要其他植被指数的控制和支持。

Abstract Protection of air and groundwater as an adaptation to climate change is currently one of the main economic and social challenges at both the global, national, regional and local levels. This is confirmed by the author’s review of the literature in this area. Higher wealth of Polish municipalities is not always consistent with greater municipal involvement in environmental protection and its results, which requires deeper analysis. Factors such as the nature of municipalities and the natural conditions of municipalities due to their spatial location are also important. The subject of this article’s research is a comparative analysis (based on detailed indicators of environmental governance of the Central Statistical Office (CSO)) of the degree of involvement of 30 Polish municipalities of varying wealth in air and groundwater protection, as well as a comparison of their natural conditions in terms of forest cover and biodiversity, which should promote better adaptation to climate change at the local level.

Abstract The purpose of the article is the general characteristics of military residential architecture built in the 1920s and 1930s in the 2nd Polish Republic. In the newly restored Poland the most pressing problem was the improvement of the housing conditions of the population. The military, who contributed the most to the reinstating of independence held special privilege with the state officials. Therefore, the problem of their quartering was resolved with utmost preference. After an unsuccessful period of trial and error with traditional and light timber frame construction the government addressed this problem systemically establishing the Military Accommodations Fund with a dedicated budget for creating typified, repeatable solutions. The MAF commissioned specific designers, held open as well as limited competitions and hired a cadre of architects and engineers to come up with designs that could rapidly and cost effectively replenish the housing base with functional, hygienic solutions. Because the MAF was well funded, the most prominent polish modernist architects readily cooperated with the organization making Polish interwar architectura militaris an engine of modernization.

Abstract The current research represents a pilot study for application of the Perpendicular Vegetation Index (PVI) for an area with forests in Bulgaria. It is the first of its kind when it comes to forest studying in the country to the best knowledge of the author. When it comes to soil background Landsat images and other spectral data may be used for monitoring forest territories as well. The study area is Pernik Province which is located in the western parts of Bulgaria. The main aim is to investigate the PVI for the forests of Pernik Province. The index has been calculated by the application of Landsat 8 bands. The PVI has been processed for several months of different years. The main focus is both on the beginning and the end of the growing season when there are significant changes in leaf biomass. The results are promising and show typical vegetation features in the beginning of the growing season (April), a well-developed vegetation (July) and a steadily decreasing biomass in November.

Abstract The major goal of this study is to determine the bioaccumulation of heavy metals in the tissues and bones of Red Hybrid Tilapia (Oreochromis niloticus) and Mackerel (Rastrelliger kanagurta) taken from two distinct sites in Terengganu state, Malaysia, namely Kijal and Paka. Zinc (Zn), copper (Cu), nickel (Ni), and lead (Pb)were the metals examined. Soil analysis also was carried out for the same elements. The tissues and bones of the fishes were separated before further analysis was made. Drying process technique was used to determine the moisture content for all samples at 80 °C for 24 hours. Water content ranged between 70 & 77%. Triplicate samples were evaluated by using Atomic Absorption Spectrophotometer (AAS) to find out heavy metals concentration. Oven and Teflon beakers were used to fully digest all solid samples at 120 oC for 3 hours. Highest readings of Zn, Ni and Pb were found in the fish bone for the samples collected from both mentioned locations. However, different pattern was noticed for Cu where higher values were found in the tissues for the same samples. Values of Pb in the tissues were higher than the acceptable value in edible fish by Food and Agriculture Organization (FAO); 1 ppm and Malaysian Food Act (MFR) & World Health Organization (WHO); 2 ppm, whereas values of Cu, Zn were in the acceptable range set by the same organizations. No values recommended for Ni by MFR. In general heavy metals in the bones and tissues from both locations can be sorted in descending order as follows; Pb>Zn>Cu>Ni. Soil samples collected from both locations showed different pattern where high concentration was found for Zn followed by Pb then Cu and Ni. Moreover analysis for soil samples collected from Paka River showed higher content for all elements compared to Kijal. More investigation is needed to clarify whether this contamination is solely from industry or due to geology of the area.

Abstract The architectural form of buildings is determined by many factors, one of the most important is construction technology. It remains in a close and inseparable relationship with architectural design. Contemporary technologies in construction are constantly subject to improvements, streamlining, changes aimed at increasing all kinds of efficiency (cost, thermal efficiency, labor input, etc.). One of today’s widely discussed determinants of changes in the way buildings are designed and constructed is environmental issue. An awareness of environmental degradation and climate change and their consequences prompts the search for increasingly sustainable solutions. This paper summarizes the research on prefabricated solutions and their implementation, especially in single-family residential architecture. This article presents pre-design, design, and post-design experiences related to planning and realization of single-family houses with prefabricated wall technology made of light expanded clay concrete. The authors implemented comparative qualitative and quantitative research through case studies, the method also uses experiences from their own research by design practice. The advantages and disadvantages of prefabrication in the selected technology are presented. The authors attempt to answer the question of whether the individual architectural design approach is reflected in the relevant environmental considerations, including, first, those related to the mitigation of climate change and adaptation to its consequences, and to what extent the discussed technology fits into the assumptions of climate and environmentally responsible design.

Abstract The presence of microplastics have been ubiquitously confirmed in aquatic environment possessing the potential risk to the health of ecosystem. Most studies concerning microplastics are focused on water bodies, but it is considered that sediments and sands from the beaches may to be a long-term sink for microplastics. High concentrations of microplastics have been found in sand beach in Europe and all over the world. In the present studies samples of beach sand originating from three beaches of recreational reservoirs in Southern Poland (Silesian Voivodship) were analysed. Preliminary screening tests were done to evaluate the degree of microplastics pollution of the selected sandy beaches. Samples were taken once from three places on the beaches of each reservoir. Beach sections parallel to the waterline were selected at each study at the swash zone – about 1 m above the waterline. Previously, no studies were done on the presence of microplastics in these beaches. The samples taken from the beach were homogenized and mixed with saturated NaCl solutions, after separation of microplastics the pollutants were counted under optical microscope (under magnification 40 -100 x). It was found that in all three places the microplastics occurred in the beach sand samples. The most contaminated samples originated from Lisiniec recreation park (Adriatyk) which contained 340 ± 222 particles per kg/d.m. The most abundant fractions in the examined samples were fibres and fragments, the less abundant ones were granules. It can be concluded that recreational reservoirs beaches can be significantly contaminated by microplastics particles, but simultaneously the concentrations of these micropollutants can vary a lot between the individual places.
