The monitoring of selected physicochemical parameters and chemical composition of water was conducted in 2017-2018 in the Lubrzanka river and the Cedzyna reservoir (Swietokrzyskie Mountains, Poland). The results indicate that the impact of reservoir on the quality of river water depends on natural characteristics of the catchment as well as on the present anthropogenic pressure. Retention of water in the reservoir caused seasonally diversified changes in analysed parameters, including an increase in water temperature, retention of major ions, nutrients and trace elements. Further research is needed to assess the risk of contamination of lower course of the river with metals deposited in reservoir’s bottom sediments.

The article presents the role of the newly built reservoir in the formation of the hydrochemistry of water of the Teesta River (a tributary of the Brahmaputra) in its Himalayan course. Field research were performed in the post-monsoon season of the period 2013-2015. Sampling and measuring points were located in five points over 43 km of the Teesta River in the Darjeeling Himalaya. Analysis of water along of river longitudinal profile above and below the reservoir suggest that the reservoir caused decrease most of the basic ions concentrations (Cl−, K+, Na+, Mg2+, NO3− and PO43−). An inverse trend was observed only with respect to Ca2+, SO42− and NH4+. The dam does not influent on the F− concentration. The reservoir causes minor enrichment most of the heavy metals such Cu, Ni, Zn, Cr, Cd and Sr. The lower enrichment of Teesta water below the dam indicates the water self-purification processes for metals by the Teesta Reservoir. The changes of physicochemical properties and concentrations of ions caused by the reservoir are usually normalised by environmental factors before the Teesta River outlet from the Himalayas (within 15 km of the river).

The study was performed in five fourth-order tributaries of the Bystrzyca Lubelska River (Eastern Poland, Lublin Upland), differing in the degree of river-bed transformation and level of pollution. Hydro-morphological methods (descriptive method by Ilnicki and Lewandowski - IL, and index method by Oglecki and Pawlat - OP) and biological indices based on the composition of zoobenthos (Diversity - D, and index based on proportions between the density of Oligochaeta and Chironomidae - O/Ch) permitted distinguishing of four classes, from II to V. The distinguishing of only two quality classes (III and IV) was possible by means of physical-chemical methods and by benthic index BMWP_PL. Those two methods seem to show the lowest sensitivity to the spatial variability of the environment quality. The BMWP_PL index was the least sensitive to year-to-year environmental changes, and O/Ch was the most sensitive. Relatively high conformity was obtained between hydro-morphological assessments performed by means of the OP and IL methods. Results obtained by means of these tools weakly corresponded with the physical-chemical assessments. The latter assessments were the most similar to those obtained by means of the BMWP_PL (degree of similarity = 57%) and D (47%) indices, and considerably less in the case of O/Ch (36%). The BMWP_PL and D indices better corresponded with the results of the hydro-morphological assessment performed by means of the IL method than with those performed by means of the OP method while D index showed a reverse pattern. The O/CH index proved useful for the assessment of the degree of organic pollution of the river’s water, but not the sediments.

The paper presents the results of the hydrogeochemical analysis of sulphurous waters in the southern part of Poland in the Nida Basin region for a time span of 2014-2016. In this area occur four chemical types of natural outflows of sulphurous waters. These are: water of the SO4-(HCO3)-Ca, S type (spring Piestrzec and Senislawice), Cl-SO4-HCO3-Na, S (s. Owczary); Cl-SO4-Na, S (s. Gadawa); Cl-Na, S, I (s. Szczerbaków). Water mineralization of varies from 2.4 to 50.6 g/dm3. Geochemical modeling with Phreeqc allowed to determine the saturation state of the water solution relative to the mineral phases of the rock medium.

The “Franciszek” dipheading is one of the main components of the transportation infrastructure in the “Pomorzany” zinc and lead mine in the Olkusz ore district. The heading was cut out of the aeration zone, created by mine drainage in Quaternary sands and Middle and Lower Triassic carbonates. This study presents the results of the examination of the chemical composition of water leaks identified in the dipheading. It was found that the chemical composition of the water under examination depends on geogenic factors, mainly the mineralogical composition of the rocks that are infiltrated by the meteoric waters which feed the leaks, as well as the geochemical processes associated with metal sulphate weathering in the carbonate rock environment (with dolomites and limestones). The significant influence of anthropogenic factors was also identified, including the most important one linked to the migration of polluted waters from the surface mine facilities.

The aimof this study was to investigate the chemical composition of groundwater and the factors affecting it in the Stara Rzeka catchment located in the marginal zone of the Carpathian Mountains in theWioenickie Foothills. Nineteen samples of water were collected from wells and their pH and electrolytic conductivity were measured. The chemical composition of the samples, including 14 ions was determined by ion chromatography. Principal component analysis (PCA) allowed to isolate the factors affecting the quality of groundwater. Geological structure and anthropogenic pressure proved to be the determining factors. The cluster analysis was also used in this study and it allowed to group the analyzed waters in terms of their mutual similarity. Additionally, the chemical composition of water samples was determined with regard to their suitability for human consumption.

The purpose of this paper is to describe the variability of the chemical characteristics of springwater in the Marków Potok catchment. Five springs were selected for research purposes. The research was performed in spring and summer 2013 and 2014. Ca was found as the most common cation, HCO3 was the most common anion and NO3 was dominated in the biogenic compounds in the analysed springwater. Comparing the period of spring and summer the highest values of most of the chemical characteristics of water occurred in the summer, the lowest in the spring. It was found that chemical properies of water springs were shaped by the diverse geological structure of the catchment area, climatic conditions, the process of dilution and the biological activity of the basin.

Content available remote Diversity of Mollusca in lowland river-lake system: lentic versus lotic patches
EN
Longitudinal organisation of macroinvertebrate fauna along river is one of the most important problem commonly used to explain the functioning of flowing water ecosystems. The river system can be treated as a mosaic of landscapes patches and riverine macroinvertebrates’ community structure is a function of longitudinal changes in its key abiotic patterns. The aims of the study was to analyse the taxonomic structure of molluscs in the river-lake system, to compare river and lake malacofauna and to determine the factors responsible for its diversity in lakes and river stretches. The study based on comprehensive analysis of malakofauna sampled at 10 sites in the Krutynia River and in all 19 lakes it flows through were performed in the years 2008–1011. River Krutynia is one of the most important rivers in Masurian Lakeland (north-eastern Poland) with length of 100 km and mean annual discharge of 10.6 m3 h-1. It forms a characteristic river-lake system typical for the lakeland landscape in Central Europe. The density and taxonomic composition of molluscs were found as strongly dissimilar in a local scale – between closely located lakes and between particular parts of flowing waters, divided by the lakes. Multivariate methods were used to demonstrate a clear dissimilarity of lake and river malakofauna and to show that the mean content of phosphorus, nitrogen and organic matter in bottom sediments were correlated with each other in lakes but not in the river. The most important species differentiating river sites into larger groups with respect to the similarity was Theodoxus fluviatilis while Stagnicola corvus and Anisus vortex were such species differentiating lakes. The numbers and percentages of Dreissena polymorpha and Unionidae were negatively correlated with nutrients in river sediments. There was a strong positive relationship between nutrients’ concentrations in sediments and the percentages of Viviparus, Obtained results of multiple regression indicate a strong effect of nutrient and organic matter concentrations in the sediments and the distance from the site to the lake on the domination structure of molluscs.

Przedstawiono wyniki 2-letnich (2006-2007) badań jakośclowych i ilośclowych makrozoobentosu, a szczególnie zmienności przestrzennej i struktury dominacji w rzece Płocicznej (Drawieński Park Narodowy). Analizowano wpływ fizycznych cech siedlisk (character przepływu, typ podłoża) i parametrów chemicznych wody na faunę denną w systemie rzeczno-jeziornym. Badania obejmowały trzy siedliska lenityczne (w górnym biegu rzeki) i dwa lotyczne (w biegu dolnym). Profil wzdłużny rzeki był silnie zróżnicowany - od odcinków z przepływem laminarnym o podłożu piaszczysto-mulistym (stanowiska 1-3) do odcinków z przepływem turbulentnym o podłożu żwirowo-kamienistym (stanowiska 4-5). W rzece stwierdzono łącznie 16 grup makrozoobentosu. Najczęściej spotykane były taksony należące do Bivalvia, Ephemeroptera, Trichoptera i Diptera. W dolnym biegu rzeki zaznaczyła się dominacja mięczaków z małżami skójką zaostrzoną (Unio tumidus) i inwazyjną racicznicą zmienną (Dreissenapolymorpha). Zbiegiem rzeki rosła liczebność organizmów, ale obniżała się bioróżnorodność oceniana przez indeks Shannona. Analizy chemiczne wody wykazały stopnlowe oczyszczanie się rzeki w wyniku przepływu przez system rzeczno-jeziorny, co obrazowały redukcje stężeń składników mineralnych i zawiesiny.

This paper presents the results of a two-year study (2006-2007) on qualitative and quantitative research of macrozoobenthos, especially a spatial variability and domination structure in the Płociczna River (Drawa National Park). The influence of the physical features of habitats (character of water flow, type of bottom sediment) and the chemical parameters of water on bottom fauna in river-lake system was analyzed. The investigations involved three lentic (upper course of river) and two lotic (lower river) habitats. The long river profile was strongly differentiated - from sections with the laminar flow and sand-silty bottom sediments (station 1-3) to turbulent flow with gravel-stony sediments (station 4-5). A total of 16 groups of macrozoobenthos were identified. Taxa representing Bivalvia, Ephemeroptera, Trichoptera and Diptera belonged to the most frequently occurring organisms. In lower course of river the domination of Bivalvia was stated with Unio tumidus and invasive species Dreissena polymorpha (Pali.). Within the river course the increase of abundance was recorded along with a decrease of Shannon biodiversity index. An analysis of water chemistry indicated a systematic purification of the river in river-lake system, which was reflected in the reduction of mineral components and suspended matter.

Four small (surface area: 0.4-2.3 ha), but relatively deep (max. depth: 6,5-7.8 m) man made reservoirs, created between 1979 and 1988 on recultivated waste heap of former sulphur mine in Machów (N 50o31'35"; E 21°37'51"), were studied in summer and autumn 2003. In autumn one lake - Kacze was not mixed down to the bottom, which could point to its meromixis. The other lakes were found to be dimictic. In all the lakes high values of total hardness, conductivity, chlorides, sulphides and low amounts of total phosphorus and nitrogen were found. Both phytoplankton and hydromacrophyte communities were poorly developed. Considerable amounts of green-yellow bacteria were also noted in plankton. The water chemistry as well as quantity and quality of plant communities reflect the chemical composition of loam soils which constitute the waste heap.

W czerwcu i listopadzie 2003 r. dokonano wstępnych badań limnologicznych czterech małych (powierzchnia: 0,4-2,3 ha), lecz stosunkowo głębokich (głębokość maksymalna: 6,5-7,8 m) antropogenicznych zbiorników wodnych, utworzonych w latach 1979-1988 na zrekultywowanym zwałowisku zewnętrznym kopalni siarki "Machów" (N 50°31'35"; E 21°37'51"). Jesienią w jednym z jezior (Kacze) stwierdzono stratyfikację termiczno-tlenową, co może sugerować występowanie meromiksji. Pozostałe jeziora uznano za dimiktyczne. We wszystkich zbiornikach stwierdzono wysokie wartości twardości ogólnej, przewodnictwa elektrolitycznego, chlorków i siarczanów oraz niską zawartość azotu i fosforu ogólnego. Zbiorowiska litoplanktonu oraz makrofitów były słabo rozwinięte. W planklonie zbiorników zanotowano także duże ilości zielono-żółtych bakterii. Zarówno skład chemiczny wody jak i jakość i ilość zbiorowisk roślinnych jest odzwierciedleniem składu chemicznego gleb zwałowiska, zbudowanego głównie z iłów krakowieckich pochodzących z nadkładu kopalni siarki.

Latem 2000 roku badano chemizm wód 6 źródeł wybijających w różnych miejscach wyspy Wolin. Oznaczano i obliczano 21 wskaźników jakości wód pozwalających określić stan równowag kwasowo-zasadowych i utleniająco-redukujących tych wód oraz ich mineralizację i zasobność w substancje biogenne. Dane pomiarowe zestawiono z wynikami badań wód źródliskowych prowadzonych w latach wcześniejszych. Wyniki badań przemawiają za tym, że wody badanych źródeł pochodzenia opadowego wypływają z dwóch odrębnych - północnego i południowego - obszarów wodonośnych na wyspie Wolin, po przesączeniu się przez warstwy gleb i skał osadowych zasobnych w CaCO, i materię organiczną. Chemizm wód badanych źródeł w okresie letnim w ostatnich latach nie ulegał istotnym zmianom.

Chemical composition of water from 6 water-heads situated in the area of Wolin lsland was examined in summer 2000. Water quality 21 indicators measured and derived parameters have been determined allowing the evaluation of acid-base and redox' balances in the waters, their mineralisation and nutrient content. The obtained data have been compared with the results of earlier studies on the chemical composition of spring waters. The results of examination indicate that water in the studied springs, the general source of water beeing the atmospheric precipitation, outlet from two separate water bearing areas in Wolin lsland - southern and northern, having permeated through the layers of soil and deposit rocks rich in CaCO3 as well as in organic matter. The composition of water from the examined water-heads did not change considerably during the recent years.

W artykule analizowano kierunki przemian zachodzące w składzie fizyko-chemicznym wód jez. Sławskiego (817,3 ha) będącego główną atrakcją turystyczną obok okolic Łagowa na Ziemi Lubuskiej. Poza tym, zlewnia tego jeziora, daje początek rzeki Obrzycy, która jest głównym źródłem wody do picia (ok. 34 tys. m3/dobę) dla miasta Zielona Góra (ok. 120 tys. mieszkańców) i wymaga szczególnej ochrony. Przeanalizowano wyniki badań fizyko-chemicznych wód jeziora Sławskiego, prób pobranych w okresie od listopada 1998 roku do października 2000 roku. Dobór wskaźników wziętych do analizy kierunków zmian chemizmu wody jeziora, wynika z ich powtarzalności w kolejnych latach badawczych. Stwierdzono, że jezioro Sławskie ulega degradującemu oddziaływaniu gospodarczej i bytowej działalności człowieka. Przejawia się to we wzroście substancji pochodzenia antropogenicznego (organicznych i mineralnych). Prezentowane wyniki są częścią obszerniejszych badań nad wpływem rolniczego i turystycznego użytkowania zlewni rzeki Obrzycy na jakość jej wód.

The article studies directions of changes in the physical, chemical and bacteriological composition of the waters in Sława Lake (817,3 ha) being the main tourist attraction in the vicinity of Łagów in the Lubuski Region. Apart from that, the basin of this lake gives the beginning to the river Obrzyca which is the major source of drinking water (approx 34 thousand m3 a day) for the city of Zielona Góra (approx 120 thousand inhabitants) thus requires a special protection. The results of physical and chemical testing of the lake waters have been analyzed involving specimens taken in the period from November 1998 to October 2000. The selection of indicators used in analyzing the directions of changes in the lake water chemistry resulted from their repeatability in the successive years under investigation. It has been concluded that Sława Lake has been negatively influenced by both economic and every-day life activities of people living in the region. It is shown in, among other things, the increase of anthropogenic substance (both organic and mineral). The presented results are a part of more extensive research work on the influence that agricultural and tourist use of the Obrzyca river basin has on the quality of its waters.
