Opis:: The natural environment is of great importance when it comes to developing a city, as it shapes its spaces, defines its roles and performs climatic and protective functions. Industrialization often requires removing landscape obstacles and vegetation to erect new buildings. An urban planner should be aware of the borders that must not be crossed. Designing new streets and buildings should follow a sustainable growth pattern, if the city landscape and its climatic conditions are to improve for the generations to come. This paper discusses the aspects of planning and managing urban spaces in such a way so as to provide their users with healthy and comfortable living conditions. The paper is based on a survey conducted to gather the opinions of members of a city community on the environment in which they live.

Opis:: W pracy przedstawiono wyniki badania składu chemicznego roślin trawnikowych oraz liści i gałęzi drzew pobranych z 21 powierzchni badawczych zieleni warszawskiej, które pogrupowano w następujący sposób: 1) zieleń wzdłuż ulic o dużym natężeniu ruchu, 2) zieleń terenów przemysłowych, 3) zieleń osiedlowa, 4) zieleń parkowa i rekreacyjna, 5) zieleń ogrodów działkowych. W masie roślinnej oznaczono zawartości: substancji organicznej, węgla organicznego, azotu, fosforu i potasu oraz metali ciężkich: kadmu, chromu, miedzi, niklu, ołowiu, cynku i rtęci. Wyliczono też stosunek węgla organicznego do azotu (C:N). Wyniki analizy chemicznej mas roślinnych oceniono w aspekcie jej przydatności do produkcj i kompostu. Stwierdzono stosunkowo małe zawartości metali ciężkich, co kwalifikuje odpady roślinne z pielęgnacji zieleni warszawskiej do produkcji dobrej jakości kompostu.
The paper presents agrochemical analysis of green clippings, leaves and branch cuttings which were collected from 21 selected places of Warsaw greenery. They were divided into five categories of greenery: 1) near busy streets, 2) industrial areas, 3) housing estates, 4) parks and recreation areas, 5) gardens. In the plant matter the content of organic matter, TOC, total N P Kand heavy metais (Cd, Cr, Cu, Ni, Pb, Zn, Hg) were determined. The C:N ratio was calculated. The obtained results were estimated according to the usability of green waste for compost production. A relatively low heavy metais content was found in green wastes, which qualifies them for good quality compost production.

Opis:: The retention of rainwater is one of the main functions of green roofs in urban areas. One of the elements influencing the variability of rainwater retention on green roofs is the configuration of the roof, i.e. the combination of drainage and vegetation layers and plants. In the article, laboratory studies regarding the influence of the vegetation layer of the green roof on the retention of rainwater were carried out, and the influence of changes in the initial moisture content in extensive and intensive substrates on retention were compared. The analysis of seven randomly selected substrates showed that the runoff coefficients range from 0.59 to 0.71. In the case of the retention, statistically significant differences were observed in terms of the rainfall volume as well as the initial moisture content.

Opis:: Tereny miejskie są narażone na emisje zanieczyszczeń pochodzących z różnych źródeł i stanowiących zagrożenie dla zdrowia organizmów żywych. Zarówno rodzaj zanieczyszczenia, jego toksyczność dla organizmów jak i formy ekspozycji a także częstotliwość ich występowania w środowisku mogą wpływać negatywnie na organizmy żywe występujące na danym obszarze. Kolejnym elementem negatywnie wpływającym na zdrowie środowiskowe, jest pęd do dobrobytu jednostek i społeczności, co w połączeniu ze słabą odpornością nerwową na sytuacje stresowe przyczynia się do obniżenia odporności organizmów na choroby stające się plagą społeczną jak bulimia, cukrzyca i choroby nowotworowe. Występująca tendencja do zwiększonej zabudowy na terenach miejskich oraz zwiększająca się liczba mieszkańców miast w Europie jak również wzrastająca świadomość tych mieszkańców o konieczności ochrony zdrowia środowiskowego, wskazuje na potrzebę poszukiwania rozwiązań alternatywnych i innowacyjnych dotyczących zieleni miejskiej. Inwestycje zaliczane do tej grupy, to zielone dachy i zielone ściany, których realizacja pozwoli na zwiększenie biologicznie czynnej powierzchni w miastach i może stanowić niezbędny element infrastruktury miejskiej przyczyniający się do podniesienia komfortu życia społeczności zamieszkujących miasta.
Urban areas are exposed on those originating in various sources, emissions of pollutants that pose a threat to the health of living organisms. The type of pollutant and its toxicity to organisms and mold exposure as well as the frequency of their occurrence in the environment can have a negative impact on living organisms occurring in the area. Another element negatively affecting the environmental health is a rush of individuals and communities to prosperity, which, combined with a weak nervous resistance to stressful situations contributes to the reduction of resistance to disease becoming the scourge of society as bulimia, diabetes and cancer. The tendency to increase building occurring in urban areas and the increasing number of urban dwellers in Europe as well as increasing awareness of the population about the need to protect environmental health, points to the need to seek alternative and innovative solutions for urban greenery. Investments included in that group, the green roofs and green walls, the implementation of which will increase the biologically active surface in the cities, may be an essential element of urban infrastructure that contributes to improving the quality of life of communities living in the city.

Opis:: A comprehensive study was conducted to monitor the emission potential from solid waste landfilled in Jordan over a period of 292 days using an anaerobic lysimeter. A 30 kg waste sample reflecting the typical municipal solid waste (MSW) streams generated in Jordan was used to simulate the influence of climate on the emission potential of landfills located in semi-arid areas. The experimental results demonstrated that a significant amount of leachate and landfill gas was produced. The methane content was found to be more than 45% and the leachate produced reached 15.7 l after 200 days. However, after 260 days the gas and leachate production rate became negligible. A significant amount of heavy metal traces was found in the leachate due to mixed waste disposal. Changes in biogas and leachate quality parameters in the lysimeter revealed typical landfill behaviour trends, the only difference being that they developed much more quickly. In view of current landfill practices in Jordan and the effect of climate change, the results suggest that landfill design and operational modes need to be adjusted in order to achieve sustainability. For this reason, optimized design parameters and operational scenarios for sustainable landfill based on the country’s climatic conditions and financial as well as technical potential are recommended as a primary reference for future landfills in Jordan as well as in similar regions and climates.

Opis:: The management of smallholder coffee plantations in Bengkulu Province has not yet conducted according to good agricultural practices. As a result, the productivity and quality of green beans produced are also low. The efforts to improve this condition need to be made in order to maintain the economic, social, and environmental sustainability of this agribusiness. The present study aimed at identifying the life cycle of the coffee agroindustry in supporting sustainable agriculture using the Life Cycle Assessment (LCA) method. The results of the study revealed that the energy input from the use of fertilizers, herbicides, manpower, and fossil fuel was 4349.08 MJ/ha. The energy output from the green beans and coffee husks was 9763.39 MJ/ha and 13524.21 MJ/ha, respectively, so the efficiency based on the input-output ratio was 5.35. The emission values to the global warming potential, acidification, and eutrophication were 109.43 kg eqCO2 , 345.70 g SO2 eq/ha/year, and 28.54 g PO4 3-eq/ha/year, respectively. The coffee agribusiness in Kepahiang Regency is categorized as organic. The coffee agribusiness was economically feasible with a Net B/C of 2.87, but the land ownership which was 1.45 ha/household and the present agribusiness conditions indicate a low sustainability rate.

Opis:: The construction of a green roof requires drainage which ought to be characterized by adequate hydraulic conductivity and be resistant to changing meteorological conditions during the winter period. A properly functioning drainage system guarantees the reliability of the entire green roof system. The article presents studies on the freeze-thaw durability and hydraulic conductivity of selected aggregates applied for constructing green roof drainage systems. The aggregates were subjected to a cyclic freezing and thawing process in 30 and 70 cycles. The obtained results indicate that the conductivity of aggregates studied using the constant head method decreases along with an increase in the number of freeze-thaw cycles they were subjected to. This means that the indicator of freeze-thaw durability can have an indicative nature in the assessment of the usefulness of selected aggregates for constructing drainage layers. The conducted studies indicate that the deciding parameter when selecting an aggregate ought to be its hydraulic conductivity, determined accounting for the changes taking place in the freeze-thaw cycles. The equations of changes in the conductivity of aggregates indicated by the authors make it possible to assess them for practical purposes.

Opis:: Heavy metals are one of the leading environmental pollutants that are hazardous to the health of humans, soils, plants, and aquatic life. This study investigated the potential of Athyrium filix-femina, Ludwigia peruviana, and Sphagneticola trilobata for phytoextraction of Al, Ag, Cd, Cr, Ga, and Sr. To evaluate the heavy metal uptake by the plants, a pot experiment was conducted using uncontaminated soil mixed with a heavy metal solution. At the end of thirty days of planting, the bioconcentration and translocation factors were calculated. Cd accumulated to a greater degree in the shoots of A. filix-femina and L. peruviana than in their roots (8% and 12% respectively). Conversely, S. trilobata accumulated 27% more Cd in its roots than in its shoots. In all three plant species, roots had significantly higher heavy metal concentrations than shoots. These findings demonstrate that L. peruviana, A. filix-femina, and S. trilobata have high potential for phytoextraction and bioaccumulation of Cd, Sr, Ag, and Ga. The herbaceous nature of these plants, coupled with their deep roots and rapid growth rates, make them promising candidates for phytoremediation in heavy metal-contaminated soils.

Opis:: Urban plants play a significant role in shaping the microclimate of the modern city, in addition to the recreational and aesthetic functions. Climate change and sharp changes in temperature affect the plant growth and development, so the question of studying the adaptive potential of the plant range in cities to temperature variability is relevant and important. Researchers and scientists around the world are studying the impact of biotic and abiotic factors on plants, but the variability of the plant organisms in the urban ecosystem is still unexplored. The data from the analysis of the frequency of occurrence plants in Kyiv green spaces show that Tilia cordata Mill., Aesculus hippocastanum L., Spiraea×vanhouttei (Briot) Zabel. and Carpinus betulus L. are most represented among the researched species. The article presents the results of the assessment of heat resistance by using the method of Matskov (1976) of 13 ornamental woody and shrubby species. Besides, the plants were separated into groups of tolerance to high temperatures. It was established that the T. cordata plants are characterized by the highest indicators of heat tolerance and they can be recommended for the creation of open landscapes. The A. hippocastanum, Catalpa bignonioides Walt., S. vanhouttei and Forsythia europaea Degen & Bald. plants are characterized by ‘moderate tolerance’ indicators to high temperature stress, therefore they can be recommended for the creation of semi-open/open landscape types. Consequently, for the formation of semi-open landscapes, using the species Platanus occidentalis L., Quercus robur L., Q. rubra, Syringa vulgaris L., Berberis thunbergii DC. and Ligustrum vulgare L. which were assessed as ‘moderately sensitive’, is recommended. The leaves of the Carpinus betulus L. and Ribes aureum Pursh. plants were most vulnerable to high temperature stress; therefore, the species are recommended for the formation of closed landscape types. Despite the comparative classification of ornamental plants in terms of heat-resistance, many issues remain unstudied and need to be clarified in terms of ecology, physiology, biochemistry and phytopathology for the plants of urban green spaces.

Opis:: The principles of sustainable development and green chemistry are priorities in the development of new technologies for the extraction of useful biologically active substances, for example, in the manufacture of medicines. The processes of extracting substances from plant raw materials have many applications. Intensification of such processes, reducing their duration, energy consumption and consumption of the extractant is urgent. The object of the reseach is the green approach to intensify the extraction processes of polysaccharide substances from plant materials. The research methodology was experimental with statistical data processing. In the field of experimental research was the process of the influence of pulsed, alternating and direct current on the intensity of aqueous extraction of polysaccharides from plant materials. The high efficiency of intensification of extraction by a pulsed electric field was studied. The process can reduce the time for obtaining water-soluble polysaccharides by 3 times in comparison with traditional pharmacopoeial convection methods and reduce energy consumption by 20 times. The significance of the pulse current parameters for effective extraction was determined: the referred pulse shape, the frequency of the pulse current for extracting the maximum amount of water-soluble polysaccharides, the pulse duration, and the optimal processing time. The green approach to the use of a moderate electric field of pulsed current to accelerate the extraction of biologically active substances is the basis of the method of intensification of other traditional mass transfer processes for the sustainable development of technology.

Opis:: Emulsion Liquid Membrane (ELM) has garnered much attention, for its simple operation and high selectivity for the target solute. For an ELM process to be successful, emulsion stability and formulation of liquid membrane are the two main criteria. This study investigated an ELM formulation to identify a suitable green surfactant over the ordinary ones to reduce the utilization of chemicals. The stability of water-in-oil-in-water (w/o/w) was assessed in the following ways, by altering the concentrations of the egg yolk and NaOH, homogenizer speed, and emulsification time. To ascertain the favorable conditions for phenol extraction, several experiments were performed, adopting the batch process, which included many parameters, like the influence exerted by the pH of the external feed, concentration of surfactant, concentration of the internal phase, time of emulsification, homogenization speed and mixing time. Lower breakage and greater extraction efficiency (0.83% and 82.06%, respectively) were attained at 3.5 pH of the external feed, 4% (v/v) of the surfactant, 0.1 M of NaOH, 7 min of emulsification time, 5800 rpm of homogenizer speed and 3 minutes of mixing time. From the results of this study, egg yolk emerged as a good green surfactant. Thus, the ELM process holds promise as an effective technology for stripping phenol from aqueous solutions.

Opis:: The building objects show a wide variety. Among them, we can distinguish buildings and various building constructions. In addition to the fact that they are of various sizes, they perform different functions, while their purpose and use generates various problems, they can be made using various materials, different technologies and construction solutions. Therefore, the decision on which solutions to apply may be difficult to make. In this situation, it is good to develop several alternative solutions for their comprehensive comparison. In addition, the existing regulations that originate in the EU directives, in many cases impose the obligation to develop several variants of future investments and analyze them taking into account many factors. In the EU recommendations, the analysis related to the impact of construction investments on the environment is of highest importance. The ISO 14040–1404X regulations created and introduced by the European Union are the most important tool for a global assessment of the environmental impact of a product, facility and service. They relate to the environmental impact assessment of the entire Life Cycle Assessment (LCA), and their assumption is to identify and minimize any environmental impacts that may arise from the production, use and disposal of the product. Research should include specific stages according to the LCA evaluation system: determination of the purpose and scope of the assessment, inventory of input and output data and the impact assessment. The following research methods were used: source materials analysis, library query, advanced data collection methods through online surveys, LCA assessment, multicriterial methods. The research conducted by the author showed that the analysis involving selected problems related to the object-environment interaction is dominant. However, in practice it is difficult to find the analyses covering the entire lifecycle of an object in accordance with the LCA procedure and examples of comparison of specific design solutions within the variant assessment procedure taking into account the LCA procedure. The aim of the article is to show how such procedure can look while comparing the exemplary variants of a construction project. The article presents an example and diagrams of conduct covering the whole life cycle of an object, and the analysis is based on specific examples.

Opis:: Shrinkage of urban green space has led to the disruption of the ecological balance. Population growth, industrial expansion, development activities and land encroachment reduce the vegetation cover of metropolitan cities including Lahore, Pakistan. Presently, Lahore is on top of all metropolitan cities in the world having worst air quality index (AQI). Thus, monitoring of the vegetation cover in urban areas is the ultimate need of the day for the conservation and protection of environment which is also the agenda of new government (Clean and Green Pakistan). Besides, Honorable Lahore High Court has also passed an order to plant trees in the oldest and biggest graveyard of Lahore to tackle the climate change issue. Considering the above-mentioned facts, the current research was carried out for the first time in Lahore, Pakistan to analyze the vegetation cover using spatio-temporal technique. For vegetation cover assessment, spatial techniques were used in the present study viz. Normalized Difference Vegetation Index (NDVI), Transformed Normalized Vegetation Index (TNDVI), Difference Vegetation Index (DVI) and supervised classification. On the basis of high magnitude of smog and air pollution issue, four recent years were selected, i.e. 2015, 2016, 2017 and 2018 to observe ground reality. The results of the study revealed the depletion of vegetation cover in cemeteries at an alarming rate. Furthermore, the results of study revealed no significant change in green cover in Miani Sahib after the passing order of Lahore High Court of plantation in the graveyard.

The scope of the research included morphological analysis and elemental composition, specific surface area, pore volume and diameter, losses on ignition and the amount of elements leached from materials. The results of the research allowed assessing the impact of physicochemical properties and thermal modification on the efficiency of phosphorus binding by these materials. All the tested sorbents show the highest calcium content among the elements with the ability to bind phosphorus. The size of the specific surface does not determine the efficiency of phosphorus retention by the tested materials; therefore it is advisable to study the mechanism of its binding. The thermal modification process, along with the increase in the treatment temperature, improves the regularity of marl and travertine structures, which also manifests itself in increasing the efficiency of phosphorus removal.
