Opis:: The surface water quality and level of metal contents in the contamination of the Toplluha river sediment were determined by means of statistical techniques and pollution indicators. The samples of water and sediments were taken in five different locations along the Toplluha river in the spring period 2013 and 2019 using standard methods for analysis. International standards (WHO 2004) were used to assess the quality of water. The samples of water in some of the locations were above these criteria levels. The heavy metal contents in the sediment were in the following order: Cu > Zn > Cr > Ni > Pb > Cd. For the evaluation of the heavy metal content, some factors were applied: enrichment factor (EF), pollution load index (PLI) and index of geoccumulation (Igeo). Cu and Pb have a significance enrichment according to the calculated EF values. The Igeo index values for Cu and Zn were at a higher level. The PLI index values were at a progressive high level from stations S3 to S5. Therefore, the preliminary treatment of the discharging waters is indispensable.

Opis:: Hydropower is one of the renewable energy sources. Hydropower plants generate electricity using the kinetic energy of flowing water. Although hydroelectric power plants are not as prominent as solar or wind farms, it should be noted that they generate the most significant amount of the power. They are also the most technically advanced projects. Power plants are built with different technical parameters of turbines, different sizes of dams or weirs and different ways of exploiting the energy of flowing water. A common feature, however, is the significant impact of hydroelectric power plants on the functioning of adjacent regions. The paper divides this impact into economic and local development, landscape, and ecological functions, emphasizing the interaction of these influences. The paper discusses the hydromorphological changes taking place in the immediate vicinity of the structure, as a consequence of channel development. The processes of aggradation and degradation of the channel are the answer to hydrodynamic equilibrium loss. These hydrodynamic processes are associated with the subsequent ecological response of the habitat. The most important of these include the dynamic equilibrium loss by the river and the subsequent morphological parameters striving to restore it according to Lane’s relation, known as the most important principle in the fluvial morphology science. The impact of the hydropower plant on the fluvial environment results, first of all, from a significant environmental impact of the damming of the river itself. If the structure is correctly designed, maintained, and operated, it allows controlling the water conditions upstream and downstream with simultaneous energy production. Due to several geometric, hydraulic, and granulometric changes, and further, the resultant economic, landscape, and natural changes that significantly affect the operation of a region, these should be considered as early as the design stage and should be an integral part of any hydroelectric project.

Opis:: The concentrations of zinc and cadmium were determined in the sediment cores sampled from the floodplain and the channel in the middle reach of the Biała Przemsza River valley (southern Poland). The results were compared to the river water and groundwater chemistry in order to reveal the average extent of the hyporheic flow. The loss of river waters through the river bed due to the natural migration modified by the drainage of the lead-zinc ore mine caused the strong pollution of the river bed sediments with heavy metals to the depth of almost three meters below the water table in the river. Moreover, the similar groundwater and river water chemistry at that depth suggests that the vertical extent of the hyporheic zone, which exceeds a depth of several meters below the channel, can be affected by the drainage of river waters by the lead-zinc mine. The lateral extent of the hyporheic flow, indicated by changes in groundwater chemistry and elevated heavy metal concentrations in the sediments, was of the order of dozen of meters. The investigation documents the large impact of the secondary in situ enrichment of sediments with heavy metals in the hyporheic zone.

Opis:: The study was carried out in the main branches of the Lower Oder River, differentiated in terms of sediments composition. The aim was performing a comparative studies on the differences in Ostracoda fauna inhabiting various types of sediments. Following bottom sediments were distinguished: hard, sapropel/hard, sapropel and Chironomidae mat. The packet of CANOCO v.4.5 programs was used to investigate the interdependence between the species composition and environmental parameters. Eighteen taxa were found of which 16 were identified to the species level. It was a comparatively high number considering the fact that the samples were collected exclusively from the benthic zone and solely from the main river bed, without floodplain. Physocypria kraepelini was an eudominant and Darwinula stevensoni and Cypria ophtalmica were dominants. The samples collected from the sapropel were characterised by the highest density. The case of hard sediments the status of domination was retained as above, but there appeared a new dominant, i.e. Potamocypris unicaudata . The most unique structure of domination was observed in the case of Chironomidae mat, with Limnocythere inopinata as an eudominant and Cypridopsis vidua and P. unicaudata as dominants. As for the species diversity, the hard sediments were characterised by the highest value of Shannon-Wiener Diversity Index, the sapropel/hard sediment was the lowest. The type of river bottom to a great extent affects the density and taxonomic composition of the Ostracoda in rivers. The waters of the Oder River, rich in oxygen, provide favourable conditions for the development of ostracods even on the surface of sapropel sediment.

Opis:: The concentration of Cu, Pb, Zn and As in water, sediment and muscle of Oncorhynchus mykiss from the Tishgo river in the central Andes of Peru were analyzed. The water, sediment and fish samples were collected from 36 sites in three sampling sectors. The analytical determination was performed by flame atomic absorption spectrophotometry. The mean Pb concentrations in the water from the three sampling sectors showed significant differences (p < 0.05) which exceeded the values of the Peruvian standard and the WHO. The mean concentrations of Cu, Pb and As in sediment did not present significant differences (p > 0.05) in the three sectors evaluated. The redundancy analysis (RDA) revealed that the concentrations of As and Pb in water, and Cu, As and Zn in sediment significantly influence the concentration of these elements in the O. mykiss muscle. The mean concentrations of Cu, Pb, Zn and As in the O. mykiss muscle were lower than those established by international regulations. Therefore, the concentrations of heavy metals and As recorded in this study do not represent a threat to the consumption of O. mykiss from the Tishgo river.

Opis:: Heavy metals like cadmium (Cd) and lead (Pb) are pollutants that are toxic, difficult to decompose and accumulate in biota. One of the biota that lives in the waters is mullet fish. This fish is demersal, has a relatively long life period, has a specific tolerance to the aquatic environment and highly consumable in Indonesia. Therefore need to know the metal content of Cd and Pb in water, sediments and mullet fish and their relationship in Indonesia. The study used a survey method with purposive random sampling at four stations, three replications. The study was conducted from June to November 2019. Analysis of data was descriptive, F-test and correlation. The results showed that the heavy metal content of Cd and Pb between stations in the water media, sediment and in mullet fish there was a significant difference. The highest Cd and Pb were showed in station III, coming from the oil industry, domestic waste and transportation activities. The heavy metal content of Cd and Pb in water, sediment and mullet fish (Planiliza subviridis) in the Donan River, Cilacap shows results exceeding the allowed threshold and danger to human health.

Opis:: Zinc present in water penetrates into the organism of a fish either directly, through the skin and gills, or indirectly, with food taken into the alimentary canal. The toxocity of this metal is associated with the transporting function of blood, which distributes it over the whole organism. The aim of this paper was to assess the zinc content in water and bottom sediments collected from the Dunajec River, and also in selected organs of bleak (Alburnus alburnus L.). The bioaccumulation factors for this element in the muscles, liver, skin and bones of the fish were calculated from the results of the research, which was carried out in 2011. Samples of water and bottom sediments were collected twice, in July and October, at 5 research points located in Szczepanowice, Janowice, Wróblowice, Lusławice, and Zakliczyn. Twenty-nine specimens of bleak were provided by members of the Polish Angling Association (PZW — Polski Związek Wędkarski), from catches performed in the second half of July. The zinc concentration in the samples was determined by inductively coupled plasma atomic emission spectrometry at a wavelength of 206.200 nm, conducted on an Optima 7600 DV spectrometer made by Perkin Elmer. The limit of detection for zinc was 5.9 μg · dm-3. High concentrations of zinc in the water were found, indicative of anthropogenic enrichment of the river with this element. The zinc content in the analysed sediments was below the geochemical background value for bottom sediments in Poland. Zinc concentrations in the fish varied within a range from 152.6 to 352 mg ∙ kg-1 in the skin, from 158.8 to 271.3 mg ∙ kg-1 in the bones, from 27.32 to 97.35 mg ∙ kg-1 in the muscles, and from 82.39 to 230.7 mg ∙ kg-1 in the liver. The mean content of zinc in individual organs decreased in the following order: skin > skeleton > liver > muscles. Zinc concentrations in individual organs of the fish were comparable with the ones determined eslewhere in environments polluted with this element.

Opis:: In order to evaluate the degree of sediment contamination by metallic trace elements in the watershed of Oued Inaouene (North-East of Morocco), samples of surface sediments were taken along the river and at the level of the Idriss 1st dam. The objective was to obtain thorough knowledge of the environment (metallic element content, organic matter content, granulometry, and pH, EC, CaCO3 content) in order to identify the degree of pollution in these sediments. The results of analysis have highlighted a contamination accentuated by Ba, Sr, P, Cu, Pb, In fact, this element is present at very high levels, with a maximum content ppm for the samples taken upstream of Oued Inaouene. This increase is related to the physicochemical conditions of the environment, despite the diversity of sources of pollutants. The analysis of hazardous heavy metals showed the values under the detection limits. The qualitative study allowed to identifying the source of contamination, it is an anthropogenic source related to the discharges of cities in vicinity of Oued Inaouene, and natural considered as the main source of pollution by trace elements of sediments that constitute an important reserve of pollutants in the environment.

Opis:: The river Nile is a dominating physical feature of the north- eastern part of the African continent, covering areas exhibiting varieties and contrasts in topography, climate vegetation and people. So, in this study, we estimated the contamination of the Nile sediment with some major and trace heavy metals in core samples which can cause some undesirable health effects. Concentrations of all elements shows that the maximum enrichment is found in the top subsamples, while the most elements shows low contents in the lower layer reflecting the impact of human activity on the sediment contents. Different normalizing methods were used, i.e. geoaccumulation (Igeo) and enrichment factor (EF), for the influence of the natural variability in sediment mineralogy and to assess whether the concentrations observed in surface sediment represent background or contaminated levels. The study has also shown the importance of different sediment characteristics in spatial distribution of heavy metals in the sediments of river Nile. To protect the ecological system of river Nile watershed, industrial mining and agricultural activities along river stream should to be strictly regulated.

Opis:: The aim of the study was to determine the contamination transport condition with sediment in the Widawa River, which inflows to the Odra River below Wrocław city. The transport simulations have been performed by means of HEC-RAS model, which was calibrated. Study and geochemical analyses indicate that pollutions are cumulated mainly in sediment of grain size, less than 0,20 mm. It was stated that the main sources of contaminations occurring in the Widawa River bottoms are: superficial run-off, municipal and industrial wastes. Sediment bed quality from the Widawa River in selected cross-sections has been analyzed. Samples of suspended load were collected and divided into eight fractions, for which the phosphorus concentration P was calculated. Deposit particles less than 0,20 mm contained most phosphorus, i.e. 73% (3,52 ppm), and particles greater than 0,20 mm about 27% (1,30 ppm) for the whole sample volume. Relationship between the phosphorus concentration P and the sediment grain size was determined. Analysis showed that the initiation of contamination-sediment suspension in the Widawa River is well described by Engelund criterion. Simulations of the migration of pollutions together with deposits in the Widawa River showed that during average flow discharge, the transport intensity of pollution was equal 2 mg/s, and sediments 6 kg/s. In the present work the water quality of the Widawa River has been also presented.
Celem pracy było określenie warunków transportu zanieczyszczeń wraz z rumowiskiem w rzece Widawie, która wpływa do Odry poniżej miasta Wrocław. Symulacje transportu wykonano za pomocą modelu HEC-RAS, który został wykalibrowany. Badania i geochemiczne analizy wskazują, że zanieczyszczenia są gromadzone głównie w osadach o wielkości ziarna do 0,20 mm. Stwierdzono, że podstawowymi źródłami zanieczyszczeń osadów w rzece Widawie są: spływ powierzchniowy oraz miejskie i przemysłowe ścieki. Przeanalizowano jakość osadów dennych w wybranych przekrojach rzeki Widawy. Pobrano próby rumowiska unoszonego i podzielono je na osiem frakcji, dla których obliczono koncentrację fosforu P. Cząstki osadów mniejsze od 0,20 mm zawierały najwięcej fosforu tj. 73% (3,52 ppm), a ziarna większe od 0,20 mm około 27% (1,30 ppm) z całej objętości próby. Określono związek między koncentracją fosforu P a wielkością ziaren rumowiska. Z analiz wynika, że początek unoszenia osadów wraz z zanieczyszczeniami w rzece Widawie dobrze opisuje kryterium Engelunda. Symulacje przemieszczania się zanieczyszczeń wraz z rumowiskiem w rzece Widawie wykazały, że podczas średniego przepływu wody, intensywność transportu zanieczyszczeń jest równa 2 mg/s, a osadów 6 kg/s. W niniejszej pracy zaprezentowano również wyniki jakości wody z rzeki Widawy.
