Opis:: Artykuł przedstawia wyniki analiz wybranych wskaźników chemicznych osadów dennych wód Raszynki, jej dopływów oraz Stawów Raszyńskich. Odczyn osadów w większości przypadków jest obojętny lub lekko kwaśny, optymalny dla rozwoju fauny i flory środowiska wodnego. Przeważają osady mineralne lub z domieszką substancji organicznej. Zawartość azotu ogólnego i pojemność sorpcyjna zależą od pojemności substancji organicznej w osadach. Osady nie są skażone chemicznie.
The article presents results of analyses of selected chemical indicators of the bottom depo sit taken from the Raszynka River, its tributaries and several ponds located in the catchment. Reaction (pH) of the sediments was mostly neutral or slightly acidic – optimum for the growth of aquatic flora and fauna. Mineral sediments with small admixtures of organic matter prevailed. Concentration of total nitrogen and sorption capacity depended on the content of organic matter in the sediments. The analysis indicate that contamination of the bottom sediments does not exceed standards.

Opis:: The study area of the Nida valley was examined to investigate variations in groundwater and surface water levels, as well as the interaction between them. In the valley, there were three branches. The two actives were the Nida River itself and the Smuga Umianowicka branch while the Stara Nida branch was dry during the measurement session. Over a 12-month period from June 2021 to June 2022, 7 monitoring points were equipped with piezometers, comprising 5 groundwater points and 2 surface water points. The monitoring frequency was set to 30 minutes. The results of this research indicate that there are significant differences in the water level at the same observed point at different times. This study demonstrates seasonal changes in both surface water and groundwater levels with higher levels in autumn and winter and lower levels in spring and summer, which are closely tied to the changes in meteorological conditions during the research period, such as precipitation and air temperature. The study results also indicate that during summer and winter at the Nida River and its riparian area, losing stream is the primary process occurring in the studied reach. Conversely, during autumn and spring, the main process is gaining stream. At the human-maintained Smuga Umianowicka branch and in its riparian area, losing stream is the main process during summer and autumn, and gaining stream is the main process during spring. During winter, losing stream and gaining stream processes can occur simultaneously, and neither process takes place mainly.

Opis:: Water quality is an environmental priority for irrigation in rainfed agriculture. Recently, water quality has been affected by the uncontrolled disposal of wastewater, the use of chemical fertilizers in agriculture and, most significantly, by the excessive exploitation of water resources during the low season. The basin of the Maffragh in the Algerian north-east real is fed by two main rivers: Wadi El Kebir East and Bounnamoussa. From its source, the stream is continually contaminated with domestic and agricultural discharges through the tributaries causing a significant deterioration in water quality. In order to know the current state of water quality in the Maffragh basin and to determine its suitability for irrigation without any prior treatment, research has been conducted in the two streams at representative sampling points in catchment areas used for irrigating crops. To assess the quality of water and detectable compounds monitoring, laboratory methods are used. The various volumetric and colorimetric assays were carried out according to Jean Rodier. Organic parameters such as nitrites, ammonium and phosphates, were measured using a UV/VIS 6705 JENWAY spectrophotometer, at wavelengths of 543 nm, 630 nm and 880 nm respectively for nitrites, ammonium and phosphates. The BOD5 and COD parameter was measured using a DIN EN 1899-1-H51 spectrophotometer and DIN ISO15705: 2002 spectrophotometer. The performed analyses on conductivity shows oscillating values ranging between 425 and 495 μS∙cm–1 for January 2018, while for the low water level of July 2018 the conductivity varies between 433 and 796 μS∙cm–1; this parameter is determinant for water quality assessment and its use for irrigation. Beside the conductivity test, the Riverside–Wilcox diagram was applied, to combine conductivity and sodium absorption rate (SAR). The obtained results of the two seasons show satisfactory results in the applicability of the water to irrigate in the basin.

Opis:: The aim of the study was to use regenerated activated carbon to adsorb phenol from a river. Coconut shell activated carbon was derived from used tap water filter cartridges. The activated carbon was carbonised and then activated with KOH at 200°C, under a nitrogen atmosphere. The resulting adsorbent was characterised on the basis of nitrogen adsorption by Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM) analysis and point of zero charge (pH PZC). The study of periodic adsorption included kinetic and equilibrium modelling, determined the effect of solution pH on efficiency and the possibility of regeneration and reuse of the adsorbent. The efficiency of phenol removal from model water was evaluated, followed by the possibility of their adsorption from a polluted river in Silesia Province. Phenol adsorption followed pseudo-second-order kinetics. The adsorbents showed high adsorption abilities, as determined by the Langmuir isotherm model. The model fits the experimental data well. The concentration of phenol in the river was in the range of 0.45-0.77 mg∙dm-3, which means that its value was at least five times higher than the standard values. The use of regenerated activated carbon from waste filter cartridges removed phenol from the river by 78% using optimal test parameters.

Opis:: In recent years, a growing problem of water deficit has been observed, which is particularly acute for agriculture. To alleviate the effects of drought, hydrogel soil additives – superabsorbent polymers (SAPs) – can be helpful. The primary objective of this article was to present a comparison of the advantages resulting from the application of synthetic or natural hydrogels in agriculture. The analysis of the subject was carried out based on 129 articles published between 1992 and 2020. In the article, the advantages of the application of hydrogel products in order to improve soil quality, and crop growth. Both kinds of soil amendments (synthetic and natural) similarly improve the yield of crops. In the case of natural origin polymers, a lower cost of preparation and a shorter time of biodegradation are indicated as the main advantage in comparison to synthetic polymers, and greater security for the environment.

Opis:: Several conjunctive use approaches can be distinguished. Drought cycling of groundwater (GW) usage and storage relies on more surface water (SW) during wetter years and delivers more water from GW during drought years. This method has the benefit of temporal changes in water availability. Additionally, it is usually desirable in areas with internal variability of SW where surface storage of wet-year surpluses is uneconomical, suffer excessive evaporative losses, or cause unacceptable environmental disruption. In previous studies, the purpose of operating the drought cycling was to reduce operating costs. In these studies, the objective function of the proposed model was to minimise the present value cost derived from the system design and operation to satisfy a predefined demand during a finite planning and operation horizon. However, it is important to consider other objectives in operating water resources systems, including minimising water shortages accurately. Hence, in this study, two scenarios were focused on: 1) mi-nimising water shortagages, 2) minimising operational costs. Pareto solutions are then presented with the objectives of minimising costs and water deficit. In this study, the weighting method has been used to extract Pareto options. The results show that reducing costs from 234 to 100 mln USD will increase water shortage from 9.3 to 11.3 mln m3.

Opis:: Developments in agriculture, industry, and urban life have caused the deterioration of water resources, such as rivers and reservoirs in terms of their quality and quantity. This includes the Saguling Reservoir located in the Citarum Basin, Indonesia. A review of previous studies reveals that the water quality index (WQI) is efficient for the identification of pollution sources, as well as for the understanding of temporal and spatial variations in reservoir water quality. The NSFWQI (The National Sanitation Foundation water quality index) is one of WQI calculation methods. The NSFWQI is commonly used as an indicator of surface water quality. It is based on nitrate, phosphate, turbidity, temperature, faecal coliform, pH, DO, TDS, and BOD. The average NSFWQI has been 48.42 during a dry year, 43.97 during a normal year, and 45.82 during a wet year. The WQI helped to classify water quality in the Saguling Reservoir as “bad”. This study reveals that the strongest and most significant correlation between the parameter concentration and the WQI is the turbidity concentration, for which the coefficient correlation is 0.821 in a dry year, and faecal coli, for which the coefficient correlation is 0.729 in a dry year. Both parameters can be used to calculate the WQI. The research also included a nitrate concentration distribution analysis around the Saguling Reservoir using the Inverse Distance Weighted method.

Opis:: The results of the study of the macrophytes of the rivers Turia, Vyzhivka and Tsyr, the right-bank tributaries of the upper reaches of the Pripet River, are presented. The species composition of aquatic and coastal aquatic vascular plants was investigated during the vegetation seasons of 2018 and 2019 at 9 observation points located along the rivers from the source to the mouth. The most numerous species composition, 57 species, was found in the Turia River, 36 in the Vyzhivka River, and 28 species were identified in the Tsyr River. The macrophyte index for rivers (Pol.: makrofitowy indeks rzeczny - MIR) was determined from the results, and the ecological state of the rivers was assessed according to the methodology of the macrophyte assessment of rivers (Pol.: makrofitowa metoda oceny rzek - MMOR). The investigation showed that water quality in the Turia River on sites No. 1, 3 and 4 belongs to class III, satisfactory category. The surface water quality on site No. 2 of the Turia River belongs to class II, a good category. The water quality in the Vyzhivka River on all test sites belongs to class II, a good category, which testifies to favourable ecological conditions for the development of higher aquatic plants along the whole course. The water quality in the Tsyr River on test site No. 8 (Kamin-Kashyrskyi, upper course) corresponds to class II, good category. On test site No. 9 (middle course), the quality of surface waters of the Tsyr River worsens to the class III, satisfactory category.

Opis:: Badania prowadzono w latach 2002-2005 w cennych pod względem przyrodniczym terenach karpackich. Ich celem było określenie koncentracji działalności gospodarczej związanej z obsługą ruchu wczasowo-aturystycznego na wybranych obszarach Podhala oraz jakości wód powierzchniowych odpływających z tego obszaru. Badaniami objęto zlewnie Białego i Czarnego Dunajca oraz Białki, istotnie różniące się liczbą napływających turystów. Stwierdzono, że najbardziej intensywną działalność gospodarczą prowadzi się na typowo turystycznych obszarach zlewni Białego Dunajca. W Zakopanem liczba podmiotów gospodarczych w przeliczeniu na 1 000 stałych mieszkańców wynosiła 165, a w Poroninie, Białym Dunajcu i Kościelisku 60-78. W rolniczej gminie Czarny Dunajec wskaźnik ten utrzymywał się na znacznie niższym poziomie i wynosił 26 podmiotów gospodarczych na 1 000 mieszkańców. Konsekwencją takiej działalności gospodarczej było znacznie większe stężenie substancji chemicznych w wodach Białego Dunajca niż Czarnego Dunajca i Białki. Stężenie PO₄ było ok. 3,3 razy, N-NO₃ ok. 1,4, Na 1,2-6,0 i Cl do 2,0 razy większe.
Studies were carried out in the period of 2002-2005 in the naturally valuable Carpathian regions. The objective of the paper was to recognize the types and intensity of business activities connected with tourism services in selected regions of the Podhale as well as the quality of surface waters flowing out of region. The study involved catchment basins of the Bialy, Czarny Dunajec and the Białka, which differed significantly in the number of incoming tourist. It was found that the most intensive business activity was conducted in a typically tourist area of the Biały Dunajec. In Zakopane the number of business enterprises per one thousand residents amounted 165, at Poronin, Biały Dunajec and Kościelisko it was in the range of 60-78 units. In the agricultural commune Czarny Dunajec this indicator was significantly lower - 26 firms per one thousand residents. As a consequence of such business activities, much higher concentration of chemical substances was found in the Bialy Dunajec as compared with the Czarny Dunajec and the Białka. The concentration of PO₄ was about 3.3 times higher, that of N-NO₃ about 1.4 times, Na from 1.2 to 6.0 times and Cl two times higher in the former than in the two latter rivers.

Opis:: Monitoring of surface waters within the transboundary section of the Western Bug River showed, that during 2014–2018, a significant excess of the maximum permissible concentration (MPC) was observed for some substances for fish ponds. As a result of this, the water in the river for these substances was rated as “dirty” in terms of purity and corresponded to water quality class IV, namely: phosphorus was observed to exceed the MPC at the observation point Ambukіv village in 2015 (9.7 times), for manganese – an excess of the MPC at the observation point Ambukіv village in 2018 (9.7 times) and in point Zabuzhzhia village in 2014 (7.9 times), 2015 (8.0 times), 2017 (7.1 times), 2018 (8.3 times); for the total iron – the exceeding of MPC at the observation point Ambukіv village in 2016 (5.95 times) and 2017 (6.13 times); at the observation point Ustilug town in 2016 (5.23 times); in the observation point Zabuzhzhia village in 2016 (9.44 times) and 2017 (5.27 times). The assessment of the surface waters based on the determination of the pollution factor showed that during the study period their quality did not deteriorate but did not meet the norms. In general, surface waters of the river correspond to the second class of quality and are characterized as “poorly polluted” waters by the level of pollution.

Opis:: European cities face urban, demographic and climate challenges. According to forecasts, annual extreme phenomena will intensify - including torrential rains. Comprehensive solutions (also those based on nature), climate adaptation strategies, runoff management, incorporation of new design (e.g. sponge cities) are urgently required in order to strengthen urban resilience and to minimise the effects of extreme weather events (droughts, floods or heat islands). The aim of the research was to develop a methodology for activating selected elements of blue-green infrastructure within areas of natural and cultural protection as an adaptive tool of urban planning. Modelling of infiltration possibilities, programmed with SCALGO Live Poland software, was performed as a case study based on a research city - Sandomierz (in Poland). Selected parameters (stormwater surface runoff, chosen runoff areas, land cover) are strongly correlated with urban indicators relating to the vegetation coverage (biologically active area - BAA). Results pointed out urban units, which BAA is lower than 25% (e.g. Old Town Square, courtyards of tenement houses). Modelling was carried out for these units by concentrating on the undeveloped area for which the BAA was increased. The enhancement assumed values in the range of 41-45%. In analysed cases, an improvement (decrease) in runoff volume was obtained, even by 8.69%. Simultaneously, infiltration increased by 19.61%, calculated over entire runoff area. Implementation of solutions based on these results, in the form of appropriate planning provisions, can raise the quality of environment (e.g. improving water infiltration) and life (e.g. more effective air cooling on hot nights).

Opis:: The objectives of developing oil palm plantations should feasible economically and without causing massive erosion. This research proposes soil and water conservation strategies that are ideal and optimal for oil palm cultivation depending on land capability class. The conservation test for plants was performed according to land capability classes on a plot measuring 22 m × 4 m. Runoff and erosion rates were measured using Multislot Divisor Method. Nutrient leaching was analysed based on the content of C-organic (Ctot) (Walkley–Black method), total nitrogen (Ntot) (Kjeldahl method), P-available (Bray-1 method) and K2O (extraction with 1N NH4OAc at pH 7.0). From the results, land capability class III, cover crops (soybean) + manure (P3) treatment effectively reduced runoff and soil erosion (22.63 m3∙ha–1∙y–1 and 13.04 Mg∙ha–1∙y–1), as well as nutrient leaching, compared to other treatments. Furthermore, sediment trap + cover crop + manure (P3) controlled runoff, erosion and nutrient leaching on land capability class IV, producing the lowest runoff (129.40 m3∙ha–1∙y–1), soil erosion (11.39 Mg∙ha–1∙y–1), C-organic (1.3%), and P (1.95 mg kg–1). Soil conservation treatment significantly reduced erosion and runoff (p < 0.05) on land capability class VI. The bench terrace + cover plants + manure treatment-controlled runoff, erosion, and soil nutrient leaching.

Opis:: The intensification of agricultural production is one of the factors determining economic development. Increasing mechanisation and use of fertilisers in agriculture lead to higher yields, but at the same time they can pose a threat to the environment. The overuse of chemical fertilisers contributes to increased concentration of nutrients in agricultural runoff. One of such areas is the Szreniawa River catchment, the study area located in the southern part of Poland. In this catchment, intensive mostly mechanical ploughing is applied in, for instance, vegetable production. The area has loess soils, which with intensive ploughing are susceptible to erosion. The study aims to determine changes in the quality of flowing waters against the background of agricultural production and land-use characteristics. Surface waters were classified as class II and occurred at all analysed points. The highest concentrations of N-NO3 , N-NH 4 and P-PO 4 were found at a point in the middle of the catchment (lower part of research area). There, the lowest concentrations were recorded in 2018, which was related to the amount of precipitation during the growing season. On the other hand, the volume of plant and animal production closely correlated with the quality of surface water in the area. This was also confirmed by the land use structure. In conclusion, intensive agricultural production, mainly in terms of plough tillage causes significant hazards associated with soil erosion especially on agriculturally sensitive soils, although it provides good yields.

Analizy chemiczne wody na obecność jonów azotanowych(V), jonów amonowych i jonów fosforanowych(V) wykonano w Laboratorium Badawczym Chemii Środowiska w Falentach. Na podstawie przeprowadzonych badań nie stwierdzono poprawy jakości wód rzeki Gowienica. Zarówno w roku 2012, jak i 2013 średnie stężenie azotu azotanowego(V) z okresu badań odpowiadało II klasie jakości wód powierzchniowych, a azotu amonowego – klasie I. Średnie stężenie fosforu fosforanowego( V) wskazywało natomiast na klasę wyższą niż I i II. Źródeł występowania wysokich stężeń azotu azotanowego(V) i azotu amonowego w niektórych miesiącach upatruje się głównie w spływach powierzchniowych z pól uprawnych i w odpływach wody z gospodarstw rolnych, zwłaszcza zajmujących się produkcją zwierzęcą. Za przyczynę wysokiego stężenia fosforu fosforanowego(V) uważa się natomiast głównie odprowadzanie ścieków bytowo-gospodarczych oraz wód z oczyszczalni ścieków bezpośrednio do koryta badanej rzeki. W pracy przedstawiono także stosunek zawartości azotu do fosforu w zależności od punktu badawczego.
The paper presents results of a two-year study (2012-2013) of nitrogen and phosphorus concentrations in waters of the Gowienica River with typically agricultural catchment basin. Water quality of the river affects the waters of Lake Miedwie, which is a source of drinking water for the population of the city of Szczecin. Water samples were collected at four sites from April to October each study year. Chemical analyses of nitrate, ammonium and phosphate ions in water were performed in the Research Laboratory of Environmental Chemistry in Falenty. Obtained results showed no improvement in water quality of the Gowienica River. In both 2012 and 2013 mean concentration of nitratenitrogen classified river water to the second quality class and mean concentration of ammoniumnitrogen to the first class. Mean concentrations of phosphate phosphorus were out of class of river water quality. High monthly concentrations of nitrate- and ammonium-nitrogen originated in the surface run-off from agricultural fields and drain water from farms, especially those with animal production. The main reason of high concentrations of phosphate-phosphorus was the direct discharge of sewage waters and waters from municipal wastewater treatment plant to the river. The paper also presents the ratio of nitrogen to phosphorus, depending on the location of sampling sites. Research has been done within the Multiannual Programme – Action 1.3, conducted by the Institute of Technology and Life Sciences in Falenty.

Opis:: The research analyzed seasonal changes of the oxygen regime and related indicators on the example of water objects of the Ukrainian Polesie Region. The region shows different directions of economic use. Zebrafish (Danio rerio Hamilton–Buchanan) and the Prussian carp (Carassius auratus gibelio Bloch) were used as test objects to investigate survival responses. Dissolved oxygen (DO) concentration in water, pH values and temperatures were determined by standard methods. Based on research results, the main problems were determined pertaining to the oxygen regime of investigated waters, i.e. the increase in temperature and toxicity of the aquatic environment in the summer. A rather dangerous decrease in DO concentration, almost up to the levels of maximum allowable concentration (MAC) (4.10 mg∙dm–3 in group E1 and 6.07 mg∙dm–3 in group E2), was observed in August and it was typical for the reservoirs with a slow water movement. Flowing river waters (group E3) were eliminated due to their better aeration compared to other groups. The correlation analysis based on the presented data revealed a high and average degree of probable correlation between the DO concentration and water temperature, as well as an average degree of correlation with general toxicity determined on sensitive species of D. rerio, and in group E1 on the persistent species C. auratus gibelio as well. The interrelations and equations of the rectilinear regression can be used to predict the oxygen regime of the waters investigated and other surface waters having similar problems.
