Opis:: In connection with setting up of the Wigry Landscape Park, in 1981 the current state of Wigry Lake zooplankton was investigated. Numbers as well as the species and trophic structure of rotifers and crustaceans were analysed. The results were compared with the data obtained in 1922. It was found that the changes in zooplankton structure, having taken place during 60 years, testify to advancing eutrophication of the lake. The progress of this process is not identical in all lake basins. The northern basin seems to be most eutrophicated, because the Czarna Hańcza River which flows into this basin carries large pollution loads.

Opis:: After the displacement of population at the end of 1940s, soils of the upper San valley were subject to natural plant succession. In 1980s a large remediation programme was carried out in the studied area - the study was aimed to investigate the impact of one of the many abandoned fertilizer stockpiles. The research has shown only a relatively small and spatially limited influence of the stockpile on soil properties expressed mainly in pH changes and an increase in soil compactness. The obtained results indicate that soil, owing to its filtering role, prevents the spreading of calcium and phosphorus compounds, potentially able to eutrophicate the environment.

Powiązania:: Wiadomości Ekologiczne
Opis:: The biomanipulation approach to lake eutrophication control (Shapiro et al. 1975, Shapiro 1978, 1980) is discussed as an example of possible applications of ecological theories in environmental management. The approach is presented as a possibility of controlling phytoplankton standing crop at high phosphorus levels in lake water (Figs. 1, 2 and 3) from the top of the trophic structure of lake community, but also other biological means of controlling symptoms of eutrophication are considered.It is suggested that biomanipulation approach would allow ecologists (1) to concentrate less on alarm calls and more on devicing constructive Solutions of environmental problems, (2) to utilise more ecological theories in practical management, (3) to complement a holistic ecosystem view of nature by an organism oriented, evolutionary view, and (4) to use funds provided for applied science for further efforts to extend our understanding of nature which, in turn may bring new ideas for environmental management.The essay is an introduction to a serie of state-of-art reviews on various aspects of biomanipulation intended for the same journal.

Studies were done in winter 1996 in three ice-covered dimictic lakes of the Łęczna-Włodawa Lakeland, eastern Poland. They involved physico-chemical conditions (temperature, oxygen concentration, pH, conductivity and Secchi-disc transparency), as well as biological ones (abundance, chlorophyll a concentration and phytoplankton structure). The oxygenation of the near-bottom layers combined with the observed structure of the winter phytoplankton confirm the rate of eutrophication of these bodies of water which had already been observed in the summer.

Opis:: The objective of the study was to trace the variability of the hydrochemical conditions in three lakes of the West Pomeranian Voivodeship (Poland) - Starzyca, Maszewskie and Nowogardzkie in the annual cycle. The research was done in 2018-2019, and samples for analysis were collected 4 times a year. All analyses were performed applying standard methods. Such hydrochemical indices were determined as dissolved oxygen, chemical oxygen demand, content of orthophosphates, total phosphorus, nitrite, nitrate, ammonium, chlorophyll a and iron. The study showed that all lakes in the research cycle were characterised by a polymictic type of water mixing, and the trophic level, based on the adopted criteria, indicated advanced eutrophy, which may also be caused by anthropogenic pressure. Oxygen conditions characterised by deoxidation of the waters in the bottom layer in the spring and summer seasons, and clear oxygenation in the surface water layer (in Lake Maszewskie reaching even 188.5% in the spring) confirm the significant advancement of the eutrophication process. The supply of phosphorus and nitrogen in spring from pelagic waters in the waters of the examined lakes influences concentrations of chlorophyll a in the summer. The influence of “internal supply” (bottom waters and bottom sediments) on the amount of nutrients available for autotrophs is clearly visible in the analysed lakes - an increase in nitrogen and mineral phosphorus concentrations in relation to surface waters was observed in the bottom layer.

Opis:: In this work, the nutrients and eutrophication problem are integrated into a nature-based solution by incorporating microalgae-based nutrient removal from wastewater and collecting the residue in an anaerobic digestion plant to produce biogas that is directly exported to an existing gas-fired power plant and closes the bioresource loop. El Burullus lake in Egypt was selected as a case study because it is rich in nutrients and suitable for the integrated system. The theoretical results were promising as for one-hectare, nutrient pollution could be reduced with a total nitrogen removal rate of 4 kg•d-1, a total phosphorus removal rate of 1.1 kg•d-1, and a total COD removal rate of 9.3 kg•d-1. The digester volume corresponding to the biomass produced was 120 m3 per hectare of algae pond and the methane yield () from anaerobic digestion was 73 m3•d-1.

Opis:: This paper presents the effects of an application of Effective Microorganisms (EM) technology in line with the method developed by Sitarek, thus evaluating its effectiveness as a tool in the biological restoration of a water body. In 2012-2013, EM was applied in Muchawka Reservoir situated in the town of Siedlce (eastern Poland). Analyses of water parameters and bottom sediments were carried out in 2011, before the EM technology was implemented and again in 2013-2015 after the EM application was completed. In spring 2011, the average total nitrogen (TN) content at the surface was 3.1 mg dm-3 while the total mineral nitrogen content equalled 0.893 mg dm-3. After the EM application was completed, in the summer of 2013, the TN content was on average 2.5 mg dm-3. The content of nitrates and nitrites in the summer of 2013 reached 1.20 mg dm-3 at the most. Lower levels of such forms of nitrogen were observed in 2013 and also in subsequent years at the bathing beach (site 1) and the hostel (site 3) than at the inflow (site 4). Likewise, the highest content of phosphates was recorded at the inflow site (4), being four -fold lower at the other sites (1, 3). The average content of TP before the EM technology was applied was 0.205 mg dm-3, whereas after the application of effective microorganisms it fell down to 0.189 mg dm-3 (2013-2015). Only slight changes of TSITP indicated that waters in Muchawka Reservoir were eutrophic. After EM was applied twice, no streaks, cyanobacterial scums or pollution at the bathing sites were visible. The bacteriological evaluation of the water samples was carried out by the County Branch of the State Sanitary Inspectorate in Siedlce. The bacteriological water quality was described as “excellent”. These findings suggest that the method developed by Sitarek, combined with probiotic preparations, could be a useful tool in the restoration of water bodies, but the conclusion requires further detailed verification.

Opis:: The aim of this study was to determine the content of phosphorus and nitrogen in the bottom sediments of the Poraj Reservoir located on the Warta River, along with defining their spatial distribution and the relationship between these elements and organic matter, aluminum and iron. Samples of bottom sediments were collected on the basis of regular measurement grid of 46 points located in the area of the water reservoir Poraj. The collected samples were analyzed in terms of content of following elements, which values are in range: total phosphorus (TP) 0.06 – 5.06 g/kg, total nitrogen (TN) 0.17 – 9.66 g/kg, organic matter (OM) 0.49 – 28.41% of solid content, aluminum (Al) 2.44 – 145.15 g/kg and iron (Fe) 0.28 – 16.50 g/kg. By using of GIS system, spatial distribution of obtained results of laboratory analyzes were interpolated (Inverse Distance Weighted method was used). On basis of spatial distribution it was noted that in northern part of water reservoir bottom sediments have greater values of TP, TN and OM than in southern part. The study also included calculation of correlation between: OM and TN (n=46, R² = 0.9335), TN and Fe (n=46, R² = 0.8782), TN and Al (n=46, R² = 0.8629), OM and Fe (n=46, R² = 0.8243), OM and Al (n=46, R² = 0.7981), TP and Fe (n=46, R² = 0.7456), TP and Al (n=46, R² = 0.6209). The presented pilot studies show that the potential content of phosphorus, nitrogen and organic matter in the sediments of the water reservoir Poraj can reach a significant level. The need to plan and carry out further research allowing the evaluation of the properties of the analyzed elements and examining their potential impact on water quality in the tested water reservoir was stated.

Opis:: Samołęskie Lake is situated in the Poznań Lakeland in Greater Poland Voivodeship, Szamotuły County, Wronki District. The lake adjoins a little village of Samołęż of about 500 residents. The glacial waterbody of over 30ha acreage is a typical tunnel-valley lake having a maximum depth of over 22 meters. It predominantly serves fishing and recreation purposes offering a beach and a sailing center. Near the coastline (not in the direct vicinity) there is a farmland. The objective of the dissertation was to assess the quality of Samołęskie Lake waters that was delivered based on the studies carried out in spring and summer, when the waterbody demonstrates excessive fertility. The studies covered the analysis of the basic physical and chemical parameters of the lake water. The measurement was carried out on a fortnight basis by means of a measurement apparatus such as the photometer and the Secchi disc. The collected results are presented with the use of figures later in this paper, whereas their in-depth analysis allowed to compile and formulate conclusions. The results of studies and analyses lay the foundations to state that the quality of Samołęskie Lake waters requires continuous monitoring and application of remedial and rehabilitation measures.
