    Opis:
    The rapid development of tourism in Pangandaran causes various problems such as environmental degradation, environmental pollution and waste problems. Environmental changes can be detected using the foraminifera community. The reasearch aims to analyze seasonal distribution of foraminifera in Pangandaran waters. This research uses the survey method and descriptive data analysis. Ecological factors (salinity, temperature, sediment, depth, pH, DO, clarity, waves and currents) have affected their distribution. Temperature values ranged between 26 to 30 ºC. Salinity values ranged between 15.6 to 31 ‰. The pH ranged from 5.47 to 8.75. The DO concentration varied between 5.43 and 9.7 ppm. The average clarity of Pangandaran waters in the west season ranges from 56 to 104.5 cm. In Pangandaran waters, the abundance of the Rotaliina sub-order reaches between 75% to 86.5%, Miliolina 11.6% to 19%, and Textulariina 0.05% to 13.4%.

    Subject and purpose of work: The subject of the study is urban farming and examples of urban gardens built in selected cities in North America and Europe. The aim of the study was to determine the influence of urban farming on urban landscape. Materials and methods: A case study – analysis of the ecological, spatial and social aspects of selected examples. Results: The idea of urban farming is gaining popularity and every year there are more urban gardens in cities in North America and Europe. There are several dozen urban gardens in Poland. Their structure is diversified so as to meet the needs of local communities. The character and scale of urban farming is diversified. These gardens satisfy aesthetic, scenic, ecological, social and even economic needs of small communities. They enrich the urban landscape with new, seasonally changeable enclaves of utility and aesthetic greenery. Conclusions: Urban farming is an ecological, social and spatial factor and a favourable alternative to urban landscape transformations. The development of urban farming should be successively supported by local authorities.
    Przedmiot i cel pracy: Przedmiotem badań jest zjawisko Urban Farming i przykłady zrealizowanych ogrodów miejskich w wybranych miastach Ameryki Północnej i Europy. Celem badań jest rozpoznanie wpływu Urban Farmingu na krajobraz miast. Materiały i metody: Studium przypadku - analiza wybranych przykładów w aspektach: ekologicznym, przestrzennym i społecznym. Wyniki: Idea Urban Farmingu znajduje swoje coraz szersze rzesze zwolenników i z każdym rokiem pojawiają się kolejne ogrody w miastach Ameryki Północnej i Europy. W Polsce jest już ich kilkadziesiąt. Funkcja i struktura tych ogrodów jest zróżnicowana i dostosowana do potrzeb lokalnych społeczności. Miejskie uprawy przyjmują różny charakter i skalę, zaspakajając potrzeby małych społeczności w aspekcie estetyczno-krajobrazowym, ekologicznym, społecznym a nawet gospodarczym. Wzbogacają krajobraz miasta o nowe, zmienne sezonowo, barwne enklawy zieleni użytkowej i estetycznej. Wnioski: Idea Urban Farming stanowi czynnik ekologiczny, społeczny i przestrzenny oraz korzystną alternatywę dla przemian krajobrazu miast. Rozwój idei Urban Farming powinien być sukcesywnie wspierany przez władze lokalne.

    Opis:
    Coastal areas in Anantigha are utilized as dumpsite for industrial and domestic wastes including effluent from local industries and inhabitants of the area despite their usage for crop cultivation. Thus, the present study was designed to assess the concentration, pollution load and ecological risk of heavy metal in Anantigha coastal area. Standard pollution indices such as contamination factor (Cf), degree of contamination, pollution load index (PLI), enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk index were deployed to assess the level of heavy metals contamination in the area. The results showed that the sediment was acidic under dried conditions and low in conductivity. The mean concentration levels of all the heavy metals were lower than their mean background values except for Al. The orders of dominance for concentration of heavy metals were: Al>Fe>Mn>Cu>Zn (Station 1) and Al>Fe>Mn>Zn>Cu (Stations 2, 3 and 4). Analyzed data showed that the sediments in the area are contaminated with Al with Igeo result showing station 2 and 4 been moderately to heavily contaminated with Al while station 4 was heavily contaminated with aluminium. Station 1 had low degree of contamination, whereas station 2 and 4 had moderate degree of contamination, and station 3 showed considerable degree of contamination. The PLI result indicates unpolluted condition and the area were not enriched by the studied heavy metals as shown by EF values. Hence, the sediment in Anantigha coastal marine area was classified as having low ecological risk factor. However, the levels of these metals are not static; there is tendency for increase as a result of increased human input and activities. Hence, there is a need for regular soil testing.

    Opis:
    The aim of the research was the evaluation of the potential contamination with heavy metals in Fluvisols, used as grasslands and arable soils of Vistula River floodplain in the area of the Chełmiński and Nadwiślański Complex of Landscape Parks. The indicators proposed by Håkanson allow to evaluate the potential ecological risk of the contamination with heavy metals associated with the accumulation of one metal or a combination of multiple metals. The mean total content of Cd, Pb, Ni Cu, Zn, Mn, as well as Fe in Fluvisols at the depth of 120–150 cm was assumed as the content of the local geochemical background and it was: 1.0 mg·kg-1, 22.8 mg·kg-1, 26.9 mg·kg-1, 1.4 mg·kg-1, 60.8 mg·kg-1, 591 mg·kg-1, and 17.6 g·kg-1, respectively. The values of the indicators such as contamination factor (CF), enrichment factor (EF) revealed higher levels of the accumulation of heavy metals in the soils of grasslands, which shows that the method of their use has a significant effect on the total metal content. Contamination with heavy metals in the surface layer of the investigated Fluvisols was found, and in terms of the content with cadmium a moderate and considerable potential ecological risk was reported. Due to the fact that no unfavourable effect of trace elements on the riverside environment was proved and that the floodplain areas are under agricultural use, to evaluate the contamination with metals, the limit values for the soils of agricultural land were assumed as stipulated in the Regulation of Minister of the Environment of September 9, 2002. According to that criterion, the soils studied do not qualify as contaminated with metals. Only in one of the soil sampling points the total content of zinc was higher than the one determined as the maximum for agricultural land soils, namely 350 mg·kg-1. A significantly positive correlation was noted between the content of C org and the total content of metals as well as very numerous interactions between metals. The results of cluster analysis confirm that the method of use determines the concentration of metals in the surface layer of the Fluvisols studied.

    Opis:
    The goal of the research was to evaluate the heavy metal detection and potential ecological risks in lake’s water. Geological formations consisting essentially of sandstone and quaternary marine or dune sands characterize the study area. With a climate of the Mediterranean type winters are mild and humid, whereas summers hot and dry. At the analysis center of the Faculty of Sciences, the monitoring of ETMs is carried out by ICP-MS, the processing of data and the validation of the analysis method have been drafted according to the NF T 90-120 standard applicable to the analysis in a laboratory. The analysis covers concentrations of heavy metals, which include Cu, Zn, Mn, Fe, Pb and As, in the water. Pollution load index (PLI) values were above one (>1) which indicates progressive deterioration of the water quality. However, contamination factor (CF) values of Pb and Cu, ranging from 8.31 to 15.68 and from 5.5 to 28.05 respectively, show that the studied water remains under a strong impact by Pb and Cu. Considering the severity of the ecological risk (Er) for a single metal, the descending order of contaminants is Cu > Pb > Mn > Fe > Zn. In relation to the total ecological risk index (RI), water from the lake shows low to considerable ecological risk.

    Opis:
    This study aimed to analyze the heavy metal contamination in sediments and their potential ecological risks. The sediment samples were collected using PVC pipes and grab samplers at nine study sites in Youtefa Bay, namely five sites in the mangrove ecosystem, two sites in the estuary, and two sites in the middle of the bay. The heavy metal content was analyzed using Atomic Absorption Spectrophotometry. The results of the analysis of the heavy metal content in the sediment were in the following order: Zn > Cu > Pb > Ni > Cr > Cd > As > Hg (106.077±98.857, 28.553±30.505, 19.798±11.541, 17.665±11.457, 12.103±0.124, 2.996±1.235, 0.149±0.124, and 0.082±0.047 mg kg-1, respectively). Only the Cd content has exceeded the Threshold Effect Level (TEL) at all study sites. On the other hand, the As and Cr content has not exceeded TEL at any study site. The content of Hg, Cr, Pb, Zn, and Ni has exceeded TEL only at a few study sites. The heavy metal content in estuary sites is higher than in mid-bay and mangrove sites, which can provide the information on the sources of heavy metal contaminants. There is a significant correlation for the content of Cu, As, Pb, Cd, Zn, and Ni which can indicate that the sources of these heavy metals are relatively the same (r = 0.569 to r = 0.950). The CF and Igeo values indicate that there has been contamination of several heavy metals studied. Further analysis ( ERI ) showed that the heavy metal content in the sediments poses a potentially serious ecological risk. Most of the potential ecological risks are the contribution of Cd and Hg which have high toxicity factors and this should receive special attention from local governments and stakeholders to prevent higher contamination.

    Subject and purpose of work: Today, each united territorial community (UTC) has tourist potential, but not all can recognise, evaluate and use it. This paper deals with presenting contemporary issues and identifying prospects for green tourism development in united territorial communities. Materials and methods: This paper includes general scientific and special methods of research, in particular, analysis and synthesis, systematisation and generalization, and the dialectical approach. A dialectical method of cognition is used to specify the features of rural green tourism organisation in the EU Member States. Results: The internal potential and opportunities for its involvement in the development of green tourism in the UTC were determined. The foreign experience is analysed and the perspectives of use of their practice in the development of green tourism are considered. The complex of tasks of the UTC to ensure the development of rural green tourism in the UTC of Ukraine is highlighted. It is established that green tourism can be an additional factor in filling the revenue part of the UTC’s budget and a factor in strengthening its capacity. A SWOT analysis of the development of green tourism in the UTCs of Ukraine was out. The main directions of development of green tourism were highlighted. Conclusions: It was determined that green tourism could act as a catalyst for economic restructuring, provide demographic stability and solve the socio-economic problems arising nowadays during the formation and development of UTCs in Ukraine.

    Opis:
    Changes in habitat conditions in the area of Eastern Poland (Polesie Podlaskie), often associated with anthropopressure, cause a reduction in the number of locations and population size of valuable and rare bog plant species, including a Pleistocene boreal relict, Salix myrtilloides. The aim of this study was to determine the current conditions of occurrence of this species based on the physico-chemical parameters of peatland piezometric groundwater. The results confirm the declining trend in the number of locations and abundance of this species in the past few decades, but at the same time they confirm the wide range of amplitude of the many investigated factors. Among the groundwater parameters studied, the low level of nitrogen fractions, phosphorus fractions, cations, and DOC can be considered to be a set of conditions promoting the preservation of the Salix myrtilloides population. The higher concentrations of phosphates, sulfates, Na, Ca, and Mg as well as higher pH and electrolytic conductivity can be considered to be presumably unfavorable. The lack of significant differences in the values of the piezometric water factors investigated for the sites with different population sizes of the studied species requires the identification of other limiting factors and the implementation of programs for its active protection in Poland.

    Opis:
    The brackish water environment of the Baltic Sea is dominated by a strong gradient of salinity and along with salinity the benthic diversity decreases – salinity is regarded as the master factor regulating benthic diversity in brackish habitats. In this scheme, consistently small patches of comparatively higher or lower benthic diversity do emerge in areas where either environmental or anthropogenic impacts on the benthic habitat change drastically over short spatial distances. Hence, spatial diversity of ecological factors creates diversity among benthic colonization and community structures. We show through a logistic modeling approach the possibility to predict thereby induced benthic colonization areas and community structures inside the broad scheme of a brackish water habitat. This study bases upon quantitative macrozoobenthic abundance data collected over a period of 4 years. It clearly demonstrates the need to analyze species’ relationships in gradient systems such as the Baltic Sea and provides a tool to predict natural and anthropogenic forced changes in species distribution.
