Opis:: The subject of the studies were waste generated in suburban households, in 3-bag system. The sum of wastes generated during the four analyzed seasons (spring, summer, autumn, winter – 1 year), in the households under study, per 1 person, amounted to 170,3 kg (in wet mass basis). For 1 person, most domestic waste was generated in autumn – 45,5 kg per capita and the least in winter – 39,0 kg per capita. The analysis performed of sieved composition (size fraction) showed that fractions: >100 mm, 40–100 mm, 20–40 mm constituted totally 80% of the mass of wastes (average in a year). The lowest fraction (<10 mm), whose significant part constitutes ashes, varied depending on the season of year: from 3.5% to 12.8%. In the morphological composition of the households analyzed (on average in 4 seasons), biowastes totally formed over 53% of the whole mass of wastes. A significant part of waste generated were also glass waste (10,7% average per year) and disposable nappies (8,3% average per year). The analysis of basic chemical components of biowastes showed that in case of utilizing them for production of compost, it would be necessary to modify (correct) the ratios C/N and C/P. Analysis of the chemical composition showed that the biowastes were characterized by very high moisture content and neutral pH.

Tematy:: retention

urban areas
Opis:: Modern city development requires increasing investments in so-called green and blue infrastructure. Water deficits and frequent droughts are a motivation for the introduction of economic water management and rainwater retention. Urban areas, which are often intensively developed and sealed, have lost their natural ability to retain rainwater. This is often the cause of urban floods that occur as a result of intense rainfall events, the intensity of which exceeds the capacity of urban drainage systems. These problems are caused by low surface and soil retention. These negative phenomena force us to take certain actions related to urban hydrology, such as determining catchments in urban areas and capturing rainwater. Town and city management must also take into account the functional and aesthetic aspects with the aim to improve the life quality of residents. Rainwater management on site of the rainfall allows to combine sustainable water management with the creation of places characterized by high aesthetic and functional value. The paper outlines the policy of the city of Wrocław with respect to rainwater management and presents the proposed solutions for a selected street, large-surface parking lot and a city square. Calculating the rainfall amount correctly and then preparing a land management design allows to use rainwater in creating attractive recreation areas.

Opis:: Different compounds including toxic heavy metals ions have been used in various industrial branches for ages. Therefore, these compounds are nowadays often identified in the natural environment. Plants usually function like indirect transporters through which heavy metals, in the form of ions, infiltrate from the environment into the human and animals’ food chains. The present paper studied the influence of urban agglomeration on the accumulation of certain heavy metals in tansy. The content of heavy metals ions (Cr, Ni, Cd and Pb) was marked in the tansy leaves. Depending on the location of sampling, large variations in the heavy metal content were observed in the plant material. The research results indicate that the heavy metal content of tansy is influenced by the close “neighborhood” of a well-developed urban agglomeration such as patrol stations and factories.

Opis:: Tansy (Tanacetum vulgare L.) grows in moderate area of the northern hemisphere, in Poland – its range covers the whole country. It appears on the farm wastelands, by roadsides, on enbankments, river banks, forest lips and in open spaces. The present paper has faced the challenge of defining the influence of the environmental conditions on the mineral composition of Tanacetum vulgare leaves. The plants were picked in the blooming period from May to September 2017 in 12 natural environments of their growth and at different contamination levels. The dried and minced plant material was submitted to chemical analyses of the bio elements content (K, P, Cu, Zn, Mo) of leaves. A great variety was observed when speaking in terms of particular elements content in dependence on the position. In all tests, significant quantities of K and P were found. The study results point at the very fact that the mineral composition of Tanacetum vulgare leaves is influenced by the environmental contamination, caused by the nearby "neighbourhood" of circulation areas of high traffic volume, factories or patrol stations.

Opis:: The aim of this work is to present the selected effects of consolidation processes conducted in 2011–2014 within the Łubka region, Siemień commune and within the Zaliszcze area, Podedwórze commune, Parczew district, Lublin Voivodeship. The consolidation activities within Łubka region were conducted over the area of 156.2937 ha and involved 60 participants. Within the Zaliszcze region, the general development area amounted to 1174.2580 ha and involved 152 participants. The project of land consolidation was developed by the Voivodeship Office of Surveying in Lublin, Branch Office in Biała Podlaska. In order to assess the basic results of land consolidation, the technical-spatial parameters were applied (the index of reducing the number of plots and extension of their surface). The main effects of the conducted process of consolidation include: decrease of a general number of record plots and an increase of the average surface of them within the region, which resulted in a reduction of the number of plots and decrease of the average surface of the plot in the farmstead. Furthermore, in conjunction with the change in the distribution of individual record plots, the farm layout has improved. Numerous agritechnical and recultivating works were also conducted and a functional network of municipal roads was created.

Opis:: The conducted research aimed at establishing the pace and range of the formation of spruce windfall in Compartment 93 of the Babia Góra National Park, where in 2005 by the decision of the Park’s Director, with the approval of the Scientific Council of the Park, a monitoring area was created. During field work the range of the existing windfall area was mapped through determining its outermost points and their stabilization by means of the GPS. During the research an analysis of the aerial photographs made available by the Babia Góra National Park was carried out, in order to determine the changes in the range of the area deprived of trees. The analyzed photographs covered the area of 5 ha in Compartment 93 of the Park. The evaluation of changes in the tree layer was based on the graticule reproducing the 10 x 10 m area of the real land. The “lack of trees” was stated when the areas were exposed in at least 75%. The comparative analysis of the images from aerial photographs of Compartment 93 in 2003, 2011, 2012 and 2014 showed distinct changes in the range and size of the gaps made by fallen trees. The share of the gaps in the forest stand in the whole analyzed area increased from 2% in 2003 to over 52% in 2014. Therefore, the progression of the size of the changes is considerable and the disintegration of the tree layer is growing, especially comparing the 2003–2011 and the twice shorter 2011–2014 periods. In the analyzed periods, the increase in the gap area was similar (ca. 26%), yet the pace of the phenomenon was twice faster. The obtained results were an argument in favor of increasing the monitoring area from 0.28 ha to 1.55 ha.

Opis:: The study aims at investigating the so-called precipitation gradient, i.e. changes in the amount of precipitation depending on the elevation above sea level in the mountainous areas of southern Poland. The gradient value is specified in mm of precipitation per 100 m elevation difference. Experimental studies were conducted in two small Beskids valleys, the Barbara stream valley and the Wilkówka stream valley. Five rain gauges were installed across land elevation profiles of said valleys. Decade precipitation amounts during the summer and autumn of 2015 were recorded. The precipitation data of the national environmental monitoring from the nearby mountain and foothill weather stations from 2014–2018 were also used for the analyses. The data analyses demonstrated a large spatial variation in the amount of precipitation. The occurrence of a varied gradient, and even inverse situations i.e. greater precipitation at the locations with lower elevation, were recorded. The precipitation gradient was differentiated, particularly by the terrain exposition relative to the dominant inflow direction of moist air masses, as well as the spatial arrangement of mountain ranges.

Tematy:: toxic elements

Opis:: The research consisted in the analyses pertaining to the occurrence of elements regarded as toxic (Zn, Cu, Ni, Cr, As, Pb, Cd, Hg), the presence of which in the environment is mainly associated with economic-industrial activities in mountain soils. The research area of about 5 sq. km. included the hilltops and south-western slopes of the Magurka Wilkowicka massif. The massif is situated on the western edge of the Little Beskids near the area of Bielsko-Biała city. The concentrations of elements were measured in 50 soil samples taken from three zones: at the foothill of the massif (arable fields), on its slopes (forest areas) and on the hilltop (grassland). Additionally, the pH of the soil samples was determined. The research showed that zinc and, to a lesser degree, copper and nickel, occurred in the highest concentrations at the foot of the massif, near built-up areas, while the highest concentrations of arsenic and lead were detected in the hilltop part of the grassland. The concentrations of chromium, cadmium and mercury did not differ spatially. The analysed elements, especially zinc and lead, often occurred in the concentrations higher than those regarded as natural. It is a disturbing fact combined with serious acidity of the analysed soils (almost 60% of the samples were very acid soils), which may increase mobility of metals. The research shows that the soil environment of the Polish Carpathians may be contaminated with toxic elements not only in the neighbourhood of built-up areas, but also in the undeveloped land.

Opis:: The seaside area is one of the most forested in the country. At the same time, the forests in the coastal zone are exposed to a strong anthropogenic pressure due to a high concentration of tourism development and tourism. The aim of the study was to analyze the changes in the forest area availability of the coastal tourist municipalities of the Baltic Sea Coast in connection with the changes in the area of tourism development and tourism in this area. The analysis was conducted in dynamic terms, taking into account the years 2000-2016. In this study, all the communes that directly border the Baltic Sea were taken into account as seaside communes. The statistical data of the Local Data Bank of the Central Statistical Office were used as the source material for the implementation of the research problem addressing: the changes in the area of total forests in all coastal communes of the Baltic Sea Coast in 2000-2016, the changes in the area and population of communes, and selected data on the tourist function of the coastal communes including the data on the number of facilities and beds as well as the number of tourists visiting the coastal communes of the Baltic Sea Coast between 2000-2016. In the coastal communes, in the years 2000-2016, the forest cover index increased from 23.3 to 24.1%. Since 2000, the forest area per 1 inhabitant increased from 1741 m² to 2149 m². The increase in the forest area and average forest area per capita occurred mainly in the rural communes, large communes with the highest forest cover indicators, in the urban communes while in the communes with a strongly developed tourism function, there was an opposite tendency. The increase in the tourism load on the forest areas and decrease in the availability of forests for tourists in the municipalities and communes with the largest tourist investment (Kołobrzeg, Międzyzdroje, Władysławowo) is observed. The anthropogenic pressure and the availability of forest decreases in communes with lower population and the marginal role of tourism in their socio-economic development (Choczewo, Trzebiatów, Smołdzino, Kamień Pomorski).

Opis:: Obecnie dostępne metody oceny stopnia eutrofizacji są kosztowne, czasochłonne i wymagają posiadania zaawansowanej aparatury laboratoryjnej oraz wiedzy. Celem niniejszej pracy było określenie prostej i uzasadnionej ekonomicznie metody monitorowania skutków eutrofizacji wody na obszarze rolniczym oraz powiązanie wyników monitorowania parametrów fizykochemicznych wody z fluorescencją chlorofilu jako potencjalnego zagrożenia dla zdrowia na podstawie ustalonych poziomów alarmowych. Badania prowadzono w zbiornikach wodnych zlokalizowanych na obszarze wiejskim, różniących się intensywnością eksploatowania terenów przyległych: znajdujących się w otoczeniu obszarów intensywnie uprawianych rolniczo oraz w obszarze chronionym rezerwatu przyrody. W pracy określono wydajność aparatu fotosyntetycznego glonów oraz właściwości fizykochemiczne wody. Badania wykazały, że wzrost intensywności fluorescencji chlorofilu związany jest ze zwiększonym ładunkiem substancji biogennych oraz ze wzmożonym wzrostem mikroogranizmow zawierających chlorofil. Wyniki wskazują, na możliwość zastosowana pomiarów fluorescencji chlorofilu do oceny stopnia eutrofizacji wód. Zaprezentowana metoda ma szanse na nieinwazyjną, szybką i precyzyjną ocenę stanu fizjologicznego ekosystemów wodnych na obszarach wiejskich, szczególnie narażonych na procesy eutrofizacji.
The currently available methods for the assessment of the eutrophication degree are expensive, time-consuming and require advanced laboratory equipment and knowledge. The aim of this work was to determine a simple and economically justified method of monitoring the effects of eutrophication of water in the agricultural area and linking the results of monitoring physicochemical parameters of water with chlorophyll fluorescence as a potential health risk on the basis of established alarm levels. The research was conducted in water reservoirs located in the rural area, differing in the intensity of exploitation of adjacent areas: located in the vicinity of intensively cultivated areas and in the protected area of the nature reserve. The work determined the efficiency of the photosynthetic apparatus of algae and physicochemical properties of water. The studies have shown that the increase in the chlorophyll fluorescence intensity is associated with an raised biogenic load and an increased occurrence of chlorophyll-containing micro-fractions. The results indicate the possibility of using chlorophyll fluorescence measurements to assess the degree of water eutrophication. The presented method can be used for a non-invasive, quick and precise assessment of the physiological status of water ecosystems in rural areas, particularly vulnerable to the eutrophication processes.

The documents of III Ministerial Conference on the Protection of Forests in Europe and the notations of 1.2 resolution adopted in Lisbon have obliged Poland to run forest management according to the rules of lasting and sustainable development. The forest economy was based on a multi-use forest model with special attention devoted to its environment-creating and social role. The actions which confirmed the introduction of rules of sustainable development into forest practice included: creating 19 Promotional Forest Complexes, systematic increase of afforestation and number of reserves. Designation of Natura 2000 areas in Poland within European Network of Protected Sites was also a very important element. Amongst those areas, as much as 39% are forest ecosystems.

Opis:: Natural areas have a high value associated with the existence of a variety of priceless natural resources. It is important to employ sustainable development in these areas by protecting the natural resources. Reasonable waste management is a global need that can significantly contribute to the protection of the environment and to sustainable development simply by accepting pro-environmental behaviour patterns. Waste management in national parks on four continents was restricted by law in some countries, which is also a priority for nature conservation. In North America, individual regions are subject to the regulations on waste management, which correspond to the local needs within national parks. Low environmental awareness of both residents and tourists is conducive to the degradation of the natural environment; this is particularly true in Asia. One of the most significant threats in these protected areas is inappropriate waste management, which is related with the practice of landfilling or combustion of waste. In order to decrease the amount of waste generated, the following solutions should be implemented: the development of education to increase the environmental awareness, and planning solutions in accordance with sustainable development.

Opis:: The content of biogenic substances, i.e. ammonia (NH₄⁺), nitrates (NO₃ ^–) and phosphates (PO₄ ^3–), in the mountain stream waters was studied. The test (zero) sample was the water flowing from forest areas, while the study samples included the water from the streams flowing through extensively used sheep pastures. The impact of grazing on the water quality during high (in the rainy season) and low (in the dry period) water flows was assessed. The studies demonstrated the water contamination with ammonia, particularly during the rainy season. The contamination was also present in the test sample, so it cannot be attributed to the grazing activity. The highest nitrate concentrations were reported in the dry period. An influence of grazing on the migration of nitrates into waters was found, however, on a scale causing no contamination. The water contamination with phosphates was found. The studies demonstrated that extensive grazing did not affect the fertilisation of mountain stream water, yet the water quality may be deteriorated by the surface runoff processes and soil cover erosion.

Opis:: The research concerned the Wapienica dam reservoir, which is located in the Polish Carpathians, near the city of Bielsko-Biala. The dam closes the flow of water from the 11.1 km² catchment. The forests cover about 90% of the catchment area, while the rest of the catchment constitutes grassland areas. The reservoir has a capacity of 1.05 million m³. The collected water is intended for supplying a water supply system. The catchment is treated as semi-natural, because within its borders the only works related to forest management are carried out. The aim of the research was evaluation of the water quality in this reservoir, including trophic status, based on the analyses carried out in 2015. It was found that the water was of good quality in basic physicochemical terms (e.g. suspension ≤13 mg∙dm^-3,COD_Cr ≤11 mgO₂∙dm^-3, conductivity ≤82 µS∙cm^-1, phosphates <0.05 mg∙dm^-3, nitrates ≤5.1 mg∙dm^-3, dissolved iron ≤0.12 mg∙dm^-3). The contamination with heavy metals was not ascertained, with the exception of the zinc. The assessed sanitary indicators are worse – the bacteria of the Coli group and periodically also enterococci were observed in the reservoir water. The reservoir is not homogeneous in terms of biological production (the trophy degree). It is low in the upper part (oligotrophy generally) and increases in the part near the dam (mesotrophy, also eutrophy). The established presence of dangerous bacteria and symptoms of the reservoir eutrophication are disturbing in the context of the opinion on the purity of uninhabited mountain areas.
