Opis:
The aim of this study has been to determine the response of cyanobacteria to the lake protection and restoration measures implemented in the littoral zone of an urban lake called Jeziorak Mały. The first investigations were conducted in 1996 and were resumed in 1997-2003, 2005 and 2013, following the installation of a separator and the creation of stone accumulation sites. Long-term changes in phytoplankton cyanobacterial proportions, abundance and biomass were analyzed in relation to environmental conditions at the sites in the littoral zone (S – separator pipes, K – sites with stones and R – sites with macrophytes). Relationships between cyanobacteria and water chemistry variables were analyzed by calculating the Spearman’s rank correlation coefficient, and then with canonical correspondence analysis (RDA). The results provided evidence that water temperature, total nitrogen and iron concentration (S, R), but also PO43- in spring (S,K) were the principal factors affecting cyanobacterial development. There was a significant decrease in the share, abundance and biomass of cyanobacteria coinciding with a decrease in conductivity and PO43- following the onset of lake restoration efforts. Changes in dominant species from the ones typical in hypertrophic lakes to those typically found in eutrophic lakes took place during the research. The modifications indicated a strong initial response of cynaobacteria to the restoration measures, but the situation stabilized in 2013, when cyanobacteria returned to their previous average levels. This suggests that the introduction of lake restortation measures contributed to the lake’s improved water quality and they should be retained for efficient lake management in the future.

Opis:
Geobotanical studies conducted in spring in 2011–2012 in the Zagórów polder washland, covered by the ecological restoration programme, provided assessment of current nature value of plant communities and indicated potential directions of their further transformations as a result of changes in habitat water content levels. Based on the analyses of 77 relevés of 50–100 m2 each, prepared following the Braun-Blanquet method, water levels were assessed by phytoindication using moisture indicator values (F) according to Ellenberg et al. (1992). Moreover, nature value of vegetation was assessed based on the botanical structure, geo-historical spectrum, life form structure as well as the nature valuation index in the 10-point scale according to Oświt (2000). Based on relevés the area was valuated using the point score method according to Mahon & Miller (2003). An attempt was made to indicate potential directions of changes in vegetation, based on the determination of dependencies between certain parameters assessing its current condition and habitat conditions. Habitat water content connected with the supply of water through a network of culverts, geomorphology of the area and land use, affects the distribution of phytocenoses in the polder and their considerable diversity, which was confirmed by the identification of 19 plant communities from six phytosociological classes. Further maintenance of water relations and land use results in the transformation of plant communities: in the vicinity of culverts – towards the class Phragmitetea, in swamps and around small water bodies – towards communities of the classes Salicetea purpurea or Alnetea glutinosae, at longer distances from culverts in leveled and agriculturally utilised areas – towards the orders Trifolio fragiferae-Agrostietalia stoloniferae and Molinietalia, while in areas at valley margins the succession progresses towards communities of the class Nardo-Callunetea.

Opis:
Nymphaeion alliance vegetation is dominant floating-leaved vegetation in the Danube–Tisza–Danube hydrosystem in northwestern Serbia and comprises Nymphaeetum albae, Nymphaeetum albo-luteae, Nymphoidetum peltatae and Trapetum natantis associations. Comparative analysis of physical-chemical water parameters on localities where these – in most parts of Europe endangered and vulnerable stands – develop showed that most phytocenoses are associated with specific habitat conditions. Of the analyzed water properties, the factors that cause Nymphaeion alliance phytocenoses differentiation are primarily pH, alkalinity and COD-MnO4. Formation of the Nymphaeetum albae stands is significantly associated with the highest values of pH, COD-MnO4 and alkalinity, and the lowest nitrate, nitrite, dissolved and the total phosphorus content values, in comparison to the other studied associations. Nymphoidetum peltatae stands develop in waters characterized by the lowest pH and COD-MnO4, low alkalinity, and the highest nitrate and nitrite values in relation to the other analyzed phytocenoses. Trapetum natantis stands, on the other hand, prefer the warmer sections of the canal network, neutral pH, and the highest values of BOD5, dissolved and total phosphorus. Habitat conditions in which Nymphaeetum albo-luteae stands develop are of the widest range in comparison to other investigated phytocenoses.

Opis:
Miedwie Lake is the biggest post-glacial lake of the West-Pomeranian Voievodship. At the same time it is the fifth of the largest lakes in Poland. As regards the geographical situation, Miedwie Lake is situated centrally between three big agglomerations i.e. Szczecin, Stargard Szczecinski and Pyrzyce (Fig. 1). The lake lies on the territory of three municipalities: Pyrzyce and Warnice in the District of Pyrzyce as well as Stargard Szczecinski in the District of Stargard (Rozmiarek 1983, Szyper 1990). At the moment, the reservoir is characterised with the regular, prolonged shape resembling an ellipse. Banks are shallow, regular and sometime very wet. The lake has the belt of the nearshore reaching locally tens metres far from the lake bank, what is the reason, together with the fact that the wind blows always here, that it is convenient for practising the various kinds of water sports. The lake area amounts to 3 527 ha; maximal depth – 43.8 m; average depth – 19.3 m; water capacity – 681.7 mln m3; shore-line length – 38.8 km; water level datum 14.1 m above sea level; maximal width 3.16 km; maximal length 16.2 km. The lake’s bottom is the lowest situated area on the territory of Poland.
Ujecie wody „Miedwie” powstało w roku 1976. Do tego czasu wody jeziora odpowiadały pierwszej klasie czystości. Jednakże jakość wody zaczęła się pogarszać już po rozpoczęciu eksploatacji ujęcia, dochodząc aż do poziomu trzeciej klasy czystości. Przyczyną był brak oczyszczalni oraz PGR-y. Zanieczyszczenie zbiornika powodowało masowe śniecią ryb (siei miedwiańskiej), przy dnie pojawił się siarkowodór, masowo zakwitały glony. Dalsze pogarszanie się stanu jeziora groziło zamknięciem ujęcia wody oraz wyniszczeniem życia biologicznego w zbiorniku, jak również wokół niego. Spadek jakości wód jeziora spowodowany był kilkoma czynnikami: rolnictwo, baza rosyjska w Kluczewie, turystyka, dopływy jeziora, biomanipulacja wodami Miedwia.

Opis:
Variations in the hydrodynamic conditions were studied on the basis of 336 days of measurements with a Doppler current profiler. With wave data as a calibration reference, a semi-empirical hindcast of wave parameters is presented in the fetch- limited near-shore area for the period 1966–2008. A resultant 4–6 cm s−1 westward current dominated along the coast. Occasional fast sub-surface westward currents under modest wind forcing, as well as asymmetrical vertical profiles for westward and eastward currents indicated the influence of upwelling-related baroclinic coastal jets. The average frequency of upwelling was estimated at 17%; some of the events were identified in near-homothermic winter conditions on the basis of salinity and multi-layer flow records. While the mean sea level trend at Narva-Jõesuu roughly approximated the global estimates for 1899–2009, the annual maximum sea level increase was 5–8 mm yr−1. Both mean and maximum wave heights declined as a result of decreasing winds from the north.

Opis:
Water is a vital resource for the existence of mankind and all ecosystems on Earth. Before using it, it must be ensured that water is of good quality, within the hygienic-sanitary norms for human consumption. In recent decades, the supply of drinking water has been supplemented with the water bottled in glass and plastic bottles, which is found everywhere in the market of the Republic of Kosovo. This paper deals with the content of the label paper and the variation of physico-chemical parameters of bottled water which is extracted, analyzed, processed, filled, packaged and distributed on the market of the Republic of Kosovo and beyond as a product for consumption. i.e. In this paper 20 brands of groundwater (types of water) produced and packaged in the territory of Kosovo.

This paper examines the impact of urban discharges on the water quality of the Erenik River in the city of Gjakova, Kosovo which is the most of key factor in developing the tourism. The primary goal of this project-based research was to provide results through water analysis in order to show the impact of urban discharges on the water quality for the tourists coming. The research was carried out by taking water samples at the entrance and exit of the Erenik River, while the measured parameters of the analyses were: temperature, pH value, electrical conductivity, turbidity, permanganates, phosphorus; and chlorides. Due to the conditions, measurements were not performed for: biological and chemical expenditure, dissolved oxygen, and alkalinity of the water. In order to achieve reliable results, the experimental research model was used, applying the techniques and methods of water analysis during the period of November-December 2021. The analyzed water result and the final findings showed that urban wastes affect the water quality, in particular the pollution from the discharges in the river potentiating the condition in which the Erenik River is found.

Opis:
The aim of the study was to determine the trophic state of the Vistula Lagoon in 2007–2009. The analysis of various trophic state indices, abiotic parameters and different water classifications indicated the eutrophy and even advanced hypereutrophy of the lagoon waters. The composition, abundance and biomass of phytoplankton likewise reflect the eutrophic nature of this water body. For this lagoon, Reynold’s functional groups of phytoplankton were used as an indicator of eutrophication for the first time. The dominant phytoplankton organisms in the surface waters belong to 8 functional groups: S1, X1, F, J, K, H1, LO, M. Some key concepts of the EU Water Framework Directive were implemented in this study.
