Opis:
The Water Framework Directive 2000/60/EC is considered a very modern strategy of water management in the EU. The purpose is to establish a framework for the protection of inland surface waters by preventing further deterioration and protecting the condition of aquatic ecosystems, as well as increasing the protection and improvement of the condition of the aquatic environment by limiting emissions and losses of priority substances. It was considered that changes in the water law in Poland during the process of implementing the guidelines of the Water Framework Directive may have contributed to widening and strengthening the monitoring system of lakes and changes in their quality, especially their ecological state. This article aims to determine the changes in legal regulations in the field of water quality/ecologically state of lakes in Poland as a result of the implementation of the WFD. The EC reports indicate that some requirements are too rigorous and complicated for Member States to implement. Water monitoring was significantly expanded and modernised which lead to improvement of lake water quality in Poland. The five-grade ecological status of lake waters and standardised biological indicators were introduced. It was highlighted that the improvement of the WFD implementation process allowed for more effective water management and the development of effective strategies for the protection of lakes in Poland and other EU countries.

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:
This research was conducted in the area of Wigry Lake, which is one of the largest and deepest lakes in Poland. It consists of several parts which differ in size, depth, number of islands, chemical composition of water and the nature of shores. To assess variations in chemical composition of the pore water and overlying water, seven research positions were selected. They belong to one of three zones: profundal, littoral and dystrophic. Water characteristics are presented in statistical approach, using the background concentrations determined by the probability method. Chemical composition of the overlying water taken from profundal locations is similar to that from littoral parts of the lake. These are multi-ion waters of HCO3–SO4–Ca, HCO3–SO4–Ca–Mg, HCO3–Ca, HCO3–Ca–Mg type. They have low mineralization (268–552 mg/dm3) and are weakly alkaline (pH from 7.49 to 7.77). The situation is different with the composition of the water taken from the dystrophic lake (SO4–Ca–Mg). These are low mineralization (28 mg/dm3) and acid waters (pH = 5.35). Dominant in pore solutions is multi-ion HCO3–Ca, HCO3–Ca–Mg or HCO3–SO4–Ca–Mg water with mineralization 445–2032 mg/dm3 and pH between 7.39–8.23 (littoral positions), HCO3–Ca–SO4 and HCO3–Ca–Mg water with mineralization 479–762 mg/dm3 and pH from 7.59 to 7.89 (profundal positions). Definitely different chemical compositions have pore water from dystrophic lake: hydrochemical type changes with depth, from the HCO3–SO4–Ca, via HCO3–SO4–Ca–Na and HCO3–SO4–K–Ca, to the HCO3–O4–Na–Ca. Their mineralization is very low (49–69 mg/dm3) and pH changes from 7.25 to 8.01.

Opis:
The paper presents the evaluation of seasonal and long-term changes in selected nutrients of three lakes of the Poznań Lakeland. The lakes were selected due to the high risk of pollution from agricultural and residential areas. Water samples were taken in 6 control points in the spring, summer and autumn, from 2004 to 2014. Trophic status of the lakes was evaluated based on the concentration of nutrients (nitrates, nitrites, ammonium, nitrogen and phosphorus) and indicators of eutrophication. Studies have shown that the concentration of nutrients varied greatly both in individual years and seasons of the analyzed decades, especially in Lakes Niepruszewskie and Pamiątkowskie. The main problem is the high concentration of nitrates. In general, it showed an upward trend until 2013, especially in the spring. This may indicate that actions restricting runoff pollution from agricultural sources have not been fully effective. On the other hand, a marked downward trend in the concentrations of NH4 over the years from 2004 to 2014, especially after 2007, indicates a gradual improvement of wastewater management. Moreover, seasonal variation in NH4 concentrations differed from those of NO3 and NO2. The highest values were reported in the autumn season, the lowest in the summer. Concentrations of nutrients and eutrophication indexes reached high values in all analysed lakes, indicating a eutrophic or hypertrophic state of the lakes. The high value of the N:P ratio indicates that the lakes had a huge surplus of nitrogen, and phosphorus is a productivity limiting factor.

Opis:
A sediment core, 350 cm long recovered from Młynek Lake, northern of Poland (Warmia and Masuria Region) was analyzed with respect to their content of diatoms and chrysophyte cysts. The aim was to reconstruct the lake water level and climatic changes during the past 2500 years. The recognized diatom assemblages displayed marked floristic changes along the sediment core samples. The main change in diatom composition consists of a shift from an assemblage dominated by benthic Fragilaria sensu lato species through marked intervals to a planktonic one in distinct zones. A high proportion of benthic to plankton taxa has been reported as indicative for a lowering of the lake level with long ice cover in a cold dry climate and a shift from benthic to planktonic diatom taxa reflects arising water level with longest growing season and reduced ice cover on the lake during a warm wet climate. Multivariate statistical analysis included hierarchical ascending clustering distinguished four diatom ecological groups. The analyzed core section was divided into 11 diatom zones according to a distribution of ecological groups and variation in abundance of dominant species supported by 14C data. The results displayed a developmental history of the Młynek Lake that can be divided into 6 main phases of alternating warm wet and cold dry shifts. A distinct dominance of planktonic eutrophic indicator diatoms accompanied by a low abundance of chrysophyte cysts indicates increased lake trophicity and a general trend for the increasing anthropogenic impact.

Opis:
Nitrogen related water pollution in aquatic systems is one of the most common problems encountered worldwide nowadays. Different restoration practices have been tested to eliminate the impacts from eutrophication but no widely applicable methodology has been found until now. Extract of Yucca shidigera has been proved effective in reducing ammonia in livestock industry and aquaculture but have not been yet tested in freshwater ecosystems. In this study, the effects of yucca extract on the reduction of ammonia in Lake Koumoundourou have been investigated. Yucca extract was added at various concentrations to experimental tanks containing lake water and sediment. The results show that yucca extract significantly reduced the concentration of ammonia while other water quality parameters were relatively stable during the experiment, except from dissolved oxygen. The study indicates that yucca extract as a restoration method can be promising but larger scale experiments should be conducted to validate this outcome.

Opis:
Geographical words referring to water, such as river, stream sea or lake, have been used in language since the earliest. As water is considered essential for life in general, the names of water reservoirs and watercourses became popular and frequently used items in all languages. The present study is focused on the English names of natural water reservoirs (sea, lake) and watercourses (river, stream) and their regional spread in the 12th–15th centuries. The Old English names of watercourses and natural water reservoirs, sӕ, flod and ea, either survived in Middle English in a modified form or were (rarely) replaced by loanwords as the effect of the Norman Conquest of England in the 11th century. The research is concentrated on texts selected from the Innsbruck Corpus of Middle English Prose (Marcus 2008), with some material coming from the OED and MED. The analysis will show the extent of the loss of the original Anglo-Saxon words or their spread, frequently with a modified meaning. The analysis will also include the statistics of the terms in question in prose texts representing the chief dialects of the period. As regards the method, the present author makes use of the traditional semantic theories (e.g. Lyons 1977) and the prototype theory (e.g. Geeraerts 1997).

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:
Background. Parasitological surveys of freshwater fishes rarely include comparisons between two ecologically different bodies of water. Such studies might help to understand processes of establishment of parasite faunas in estuary areas. The results obtained could also provide useful tools for discriminating various fish populations based on the composition of their parasite faunas. The present authors attempted to study such data from Resko Lake-a freshwater coastal lagoon (6 km? surface area), and the adjacent areas of the Baltic Sea. Resko Lake, located 12 km west of the city of Kołobrzeg, is shallow (1.5 m) and is connected to the sea through a small canal (1.3 km long, 30 m wide). Material and methods. The material was collected from April 1969 and July 1970. A total of 159 perch were collected, in this number 104 fish from the lake, 43 from the sea, and 12 from the canal. Results. A total of 32 parasite species were recovered from the fish necropsied. The parasites represented 7 higher taxa: Protozoa (3 species), Cestoda (4), Digenea (13), Nematoda (5), Acanthocephala (3), Mollusca (1), and Crustacea (3). The parasite fauna of perch from the sea was definitely more abundant (31 species) compared to that of the lake (21), and the canal (12 species). Infection parameters of 13 parasite species demonstrated significant differences between the locations studied. The infection level of 6 parasite species was significantly higher in perch from the sea: Bothriocephalus scorpii, Ligula sp., Brachyphallus crenatus, Camallanus truncatus, Hysterothylacium aduncum, and Echinorhynchus gadi. On the other hand, infection levels of 7 other species were higher at the lake: Triaenophorus nodulosus, Bucephalus polymorphus, Azygia lucii, Tylodelphys clavata, Camallanus lacustris, Acanthocephalus lucii, and Achtheres percarum. The infection parameters of the fish from canal were similar to those from the lake. Interesting observations were made on the seasonality of certain parasites of both lake- and Baltic perch. The presently observed differences between parasite faunas of the fish from ecologically different adjacent estuarine locations are certainly caused by diversified environmental conditions that affected the processes of formation of the parasite communities there. Among important factors that could affect compositions of the parasite faunas could have been: availability of the intermediate hosts, exchange of waters (Baltic water influxes to the lake), fish migrations (spawning), and finally the separate identity of the two fish stocks studied.

Opis:
Badania przeprowadzono w latach 2005-2009 na jeziorze Starzyc (gmina Chociwel) w województwie zachodniopomorskim. Celem badań była ocena stanu jakości wody w jeziorze Starzyc w warunkach napowietrzania za pomocą aeratora pulweryzacyjnego. W okresie badań nie stwierdzono różnic stężenia tlenu w wodzie badanego jeziora między punktem zlokalizowanym w pobliżu aeratora a punktami badawczymi oddalonymi od niego. Stwierdzono także, że praca aeratora pulweryzacyjnego na jeziorze nie poprawiła natlenienia wody w warstwach naddennych zarówno w pobliżu aeratora, jak i w pozostałych punktach. Stężenie składników biogennych w wodzie jeziora Starzyc stopniowo malało, a średnie wartości z lat 2005-2009 kwalifikują wody omawianego jeziora ze względu na stężenie azotu mineralnego (N-min) i fosforu (P) do trzeciej klasy czystości wód jeziorowych, natomiast ze względu na stężenie jonów amonowych (NH4+) - do drugiej klasy. Dalsza poprawa jakości wód w jeziorze Starzyc zależy między innymi od wyeliminowania przyczyn zanieczyszczeń w wodzie dopływającej do jeziora, szczególnie nadmiaru azotu i fosforu.
The study was carried out in 2005-2009 in Lake Starzyc (the Chociwel community) in West Pomeranian voivodship. It aimed at estimating water quality of lake as an effect of its aeration by pulverizing aerator. In the five-year study period no differences were observed in the content of oxygen between waters near the aerator and those taken from distant sampling points. Pulverizing aeration technology used in lake did not improve aeration of near-bottom water layers next to the aerator or at distant sampling sites. Nutrient concentrations in lake water gradually decreased from the first study year. Mean concentrations of mineral N and P from the years 2005-2009 qualify water of the lake to the third class of water quality and those of ammonium nitrogen - to the second class. Further improvement of water quality in Lake Starzyc depends on elimination of pollution sources (mainly the excessive concentrations of nitrogen and phosphorus) in waters flowing into the lake.

Opis:
Badania przeprowadzono w latach 2005-2008 na jeziorze Resko Górne, gmina Połczyn-Zdrój w województwie zachodniopomorskim. Celem badań prezentowanych w pracy była ocena stanu jakości wód jeziora Resko Górne na podstawie wybranych wskaźników w warunkach napowietrzania za pomocą aeratora pulweryzacyjnego. W czteroletnim okresie badań (2005-2008) nie stwierdzono wyraźnych różnic w zawartości tlenu w wodzie między punktem zlokalizowanym w pobliżu aeratora pulweryzacyjnego a oddalonymi punktami badawczymi. Jednocześnie stwierdzono, że praca aeratora pulweryzacyjnego na jeziorze nie wpłynęła na poprawę natlenienia wody w warstwach naddennych zarówno w pobliżu aeratora, jak również w oddalonych punktach badawczych. Stężenie składników biogennych w wodzie jeziora w kolejnych latach badań malało, a na podstawie uzyskanych średnich wartości w ostatnim roku (2008) wodę można zakwalifikować do II klasy czystości wód jeziorowych ze względu na zawartość NH4+, Nmin, a ze względu na zawartość fosforanów (PO43-) do III klasy czystości [KUDELSKA i in., 1994]. Zaobserwowane w ostatnim roku badań (2008) mniejsze stężenie jonów amonowych i azotu mineralnego w wodzie jeziora Resko Górne wynika z uporządkowania gospodarki wodno-ściekowej w gospodarstwie ekologiczno-turystycznym, położonym w sąsiedztwie jeziora.

The aim of the study was to estimate water quality status in conditions of its aeration by means of pulverization aeration. During the whole study period (2005-2008) there were no significant differences of oxygen concentration in water near aerator and in that far from the device. Aerator did not improve oxygenation of near-bottom water in both sites. Nutrient concentrations in lake water decreased during the subsequent years of this study. Mean concentration of NH4+ and mineral N in the year 2008 was typical of the 2nd class water quality and that of PO43- was typical of the 3rd class [KUDELSKA et al., 1994]. Lower concentrations of NH4+ and mineral N observed in 2008 resulted from the improvement of water management and sewage handling in eco-tourist farm near this lake.

Opis:
Microplastics (MPs) has become a very serious global threat, especially to the health of animals, humans and the environment. In this study we aim to investigate the contamination of MPs in sediment, air, and aquatic biota collected from the waters of Lake Beratan in Bali Province, Indonesia. Lake Beratan is one of the strategic areas that continues to develop as a tourist destination, agriculture and fisheries, as well as a source of water for daily needs. Sediment, water, and aquatic biota samples were collected from 4 stations that represent the Beratan Lake area. Each sample obtained was then followed by the pre-treatment stage using 5 M NaCl solution. Furthermore, the extraction process for each sample used wet oxidation peroxidation (WPO) with the addition of Fe (II) catalyst. The highest average weight of MPs in the sediment samples was obtained at the 1st sampling point of 2.53% which was dominated by soft fragments. The percentage of MPs weight in the water samples was varied at each sampling point with the highest obtained at the 4th point of 99.2% and was dominated by hard-shaped fragments at all sampling points. The collected aquatic biota was also contaminated by MPs of 68% in fish and 36.40% in shrimp. The types of MPs found in the digestive tract of aquatic biota are in the form of fragments, filaments, films and foam. These results indicate that the aquatic environment of Lake Beratan, Bali has MPs content that varies in sediment, water and aquatic biota which are often consumed by the local community. This must be of particular concern and further investigation, especially regarding the environmental management of the lake area and the relevant authorities in formulating regulations to reduce the harmful effects of MPs contamination.

Opis:
Gatal Lake is located in the Kotawaringin Lama District, West Kotawaringin Regency, Central Kalimantan, Indonesia. The government and the surrounding communities use Gatal Lake for recreation, irrigation, livestock, and fisheries. Geographically, Gatal Lake, is close to oil palm plantations and palm oil processing factories that contributed to water pollution, especially the pollutants originating from plantation activities in the form of largescale use of fertilizers and pesticides. This study aimed to determine the status of the water quality of Gatal Lake, Kotawaringin Lama based on the physicochemical parameters. The samples from five stations were analyzed based on the following parameters: temperature, TDS, TSS, pH, BOD, COD, DO, nitrate, nitrite, phosphate, Pb, Cd, H2S, oil and grease, detergent, and phenol. The study was conducted using a purposive sampling method and determining the status of water quality based on Government Regulation No. 82/2001. The results of the physicochemical analysis of Gatal Lake showed that the water quality parameters which exceeded the water quality standards, are BOD (6.94 to 8.65 mg L), COD (9.58 to 15.7 mg/L), and DO (4.20 to 5.10 mg/L), while the parameters that did not exceed the water quality standards for Class I, II, III, and IV are temperature, TDS, TSS, pH, nitrate, nitrite, phosphate, Pb, Cd, H2S, oils and fats, detergents and phenols. On the basis of the STORET method, the water quality of Gatal Lake for Class I, II, and III are included in the highly polluted category, and for Class IV is in the moderate category.
