    Opis:
    The aim of the study was to analyze the content of Ni in fractions of 1.0–0.2 mm, 0.2–0.1 mm, 0.1–0.063 mm, 0.063–0.02 mm, and <0.02 mm of river bottom sediments and plants (root, stem, leaf) of broadleaf cattail (Typha latifolia), yellow water lilies (Nuphar lutea), and cowbane (Cicuta virosa). Nickel content in bottom sediment was slightly higher than the geochemical background. The largest amounts of Ni were associated with the finest fraction, while the smallest with the thickest fraction. The highest content of this element was recorded at the point Ełk Barany, which was connected with developing industry in the city of Ełk. All of the tested plants showed greater Ni contents than the amount naturally occurring in plants. In most cases, most of Ni was associated with plant roots, and the least with leaves. It has been proven that aquatic plants can be good indicators of the aquatic environment status.

    Opis:
    The purpose of the work was to determine the relationship between the state of the water environment quality of selected rivers (Zn, Cr, Pb, Cd and Cu tests in bottom sediments), and the sources of pollution resulting from the close proximity to the cities, through which they flow. The following rivers were selected for the study: the Biała river flowing through the city of Białystok, the Narew river flowing through the city of Tykocin and the village of Złotoria, the Supraśl river flowing through the village of Michałowo and Gródek as well as the Biała river flowing through the city of Bielsk Podlaski. The sediments were collected four times from the same points in 2016 in the period from July to October. The sediment samples were collected from the points located on rivers before and beyond towns and villages. The contents of the following metals were tested in the bottom sediment samples: Zn, Cr, Pb, Cd and Cu. The analyses were carried out applying the flame absorption spectrometry method. The statistical multivariate CA and FA analyzes were used. The highest contents of Zn, Pb and Cr were recorded in the bottom sediments from the following rivers: Biała (Białystok) and Biała inflow of Orlanka (Bielsk Podlaski), which resulted from the anthropogenic activity. The research also showed the impact of the agricultural activity due to the slightly elevated Cd level.

    Opis:
    The aim of the work was to analyze the content of Ni, Pb and Cd in organs (root, stem, leaf) Typha latifolia L. and Nuphar lutea as well as bottom sediments of the Ełk River and selected tributaries. An attempt was also made to indicate the factors and processes governing the behavior of the investigated metals in the water environment of the examined rivers. The research object was the Ełk River with its three tributaries - the Gawlik River, the Binduga River and the Kuwasy Canal. Samples of bottom sediments, leaves, stems and roots of Typha latifolia L. and Nuphar lutea were collected in August of 2015. The content of metals was determined by flame atomic absorption spectrometry (F-AAS). The results of analyses of sediments and plant material indicate a lack of environmental pollution by nickel (2.58-8.50 mg-kg-1) and lead (3.82-15.99 mg-kg-1) of the Ełk River and its tributaries whereas the cadmium content ranged from 0.16-0.76 mg-kg-1. Nuphar lutea and Typha latifolia L. showed a varied capacity to accumulate nickel (1.20-10.51 mg-kg-1) and lead (0.04-14.16 mg-kg-1), occurring primarily in the roots. The smallest concentration of nickel and lead was recorded in the stems. The highest concentration of cadmium (2.56 mg-kg-1) was noted in the roots and the lowest (0.01 mg-kg) in the leaves. Factor analysis pointed to the processes of mobilizing elements from bottom sediments as a result of pH drop and their uptake by macrophyte roots and sorption processes of metal ions by macrophytes from river waters and their intensive accumulation in bottom sediments.

    Opis:
    The article presents the results of studies upon metals (Pb, Zn, Cr, Ni, Cu, Co) in bottom sediments and in various parts of the aquatic plants taken from the Bug river (Poland). The metal contents in the examined environmental elements were determined by AAS technique. The aim of this study was to evaluate the content of metals in bottom sediments and macrophytes (root, stem, leaf) occurring in the Bug river. It was hypothesized that the heavy metal content in plant tissues reflects the amount of metals in sediments. It has been shown that the average metal distribution in the examined plants present in the Bug river and bottom sediments was as follows: Pb, Zn, Co, and Cu sediments>root>leaf>stem, while in the case of Ni and Cr, the contents were greater in roots than in sediment (root>sediment>leaf>stem), although the differences in contents were not large. The study showed that most metals are present in roots and only a small part of them is transported to the stem and leaves. The size of the metal movement within plants may depend on their contents. It was found that for Ni, Cr and Cu in 2014, the bioaccumulation factor was above one, which confirms the high efficiency of metals uptake from the environment as evidenced by statistical analysis. Bioaccumulation factor (BF) was smaller than one for Pb, Co and Zn, confirming the high ability to retain metals in the root. Aquatic plants are an effective barrier for the surface water by accumulating heavy metals in their biomass. Macrophytes are proposed to monitor the river pollution.

    Opis:
    The paper attempts to determine the degree of impact of discharged wastewater from five treatment plants on the Bug River ecosystem and its inflow, the Kamianka. For laboratory tests, samples of bottom sediments and aquatic plants were collected in 2014. The content of heavy metals: Zn, Pb, Ni in bottom sediments and aquatic plants (root, stem, leaf) growing close to the discharge of purified sewage, were analyzed. The amount of metals in the samples was determined applying the AAS method in its flame version. The average content of the metals determined in bottom sediments from the study points located before the treatment plant were Zn – 21.8; Pb – 11.5; Ni – 13.7 mg kg−1. However, the content of these metals was higher in samples from the collection points which were located after the place of purified sewage discharge and amounted to: Zn – 34.3; Pb – 12.2; Ni – 16.9 mg⋅kg−1. The test plants were Acorus calamus L., Nuphar lutea L., Typha angustifolia L. The content of metals in the individual parts of macrophytes (root, stem, leaf) was as follows: Zn > Pb > Ni. In the bottom sediments and aquatic plants of the Bug and Kamianka rivers, a higher content of lead, zinc and nickel was found after the discharge of treated sewage in relation to their content than before discharge, but it was not a threat to the aquatic environment of the watercourses studied. Statistical analysis showed that the amount of sewage discharged to the tested receivers influenced the content of organic matter, zinc and nickel in bottom sediments.

    Opis:
    The aim of present study was to determine the content of phosphorus in bottom sediments from rivers of the Upper Narew catchment area. The study deals with tracing the changes of phosphorus in bottom sediments on the background of the spatial distribution of point sources of this nutrient, and identifying the main factors of its enrichment related to morphometry and management of catchment. The study was focused on the Narew River in 10 measurement sections within the stretch Bondary – Tykocin and the Supraoel River, on which six measurement points were selected. During the selection of the bottom sediment sampling sites, the presence of sites where the aquatic environment is improved in phosphorus (mainly sewage treatment plants), was adopted as the main criterion. Samples for analyses were also collected from 17 smaller and larger tributaries of Narew River. The highest contents of phosphorus in bottom sediments were found in Narew River (1.31 gP kg–1 d.m.), while the lowest in river Strabelka (0.10 gP kg–1 d.m.). Comparison with other research revealed that studied sediments were characterized by a typical content of phosphorus, and locally increased amounts of this element are the result of limited, however still existing anthropogenic pressure. The results indicate a relationship between phosphorus in bottom sediments and the nature of particular rivers catchments, including the amount of sewage discharged into these rivers.
    Celem pracy było określenie zawartości fosforu w osadach dennych rzek z obszaru zlewni górnej Narwi. W pracy analizowano zmiany zawartości fosforu w osadach na tle przestrzennego rozkładu punktowych źródeł tego składnika oraz zidentyfikowano główne czynniki jego wzbogacania związane z morfometrią i zagospodarowaniem zlewni. Badaniami objęto rzekę Narew w 10 przekrojach pomiarowych na odcinku Bondary – Tykocin oraz rzekę Supraśl, na której wytypowano 6 punktów pomiarowych. W czasie doboru miejsc pobierania próbek osadów dennych za główne kryterium przyjęto obecność ognisk wzbogacania środowiska wodnego w fosfor, głównie oczyszczalni ścieków. Do analiz pobierano również próbki z 17 mniejszych i większych dopływów Narwi. Największe zawartości fosforu wykazano w osadach dennych Narwi (1,31 g kg–1 s.m.), a najmniejsze w osadach Strabelki (0,10 g kg–1 s.m.). Porównanie z innymi badaniami wykazało, że badane osady charakteryzują się typową zawartością fosforu, a lokalnie zwiększone ilości tego składnika są wynikiem ograniczonej wprawdzie, ale istniejącej presji antropogennej. W pracy wykazano, że istnieje zależność zawartości fosforu w osadach dennych od charakteru zlewni poszczególnych rzek, w tym od ilości ścieków odprowadzanych do tych rzek.

    Opis:
    The study concerns with the effect of catchment area use on lead and zinc accumulation in the bottom deposits of lakes. It was carried out in two water bodies in the Olsztyn Lakeland. The catchment areas of the investigated lakes are used for various purposes, ranging from forests to agricultural production. Lake Ardung (N 53o45, E 20o 55) is situated in the eastern part of the Masurian Lakeland, approximately 25 km east of Olsztyn. The lake has an area of 26.2 ha and a maximum depth of 3.6 m. The lake’s catchment area of 1539 ha is covered by farmland in 2 %, grassland in 2 %, fallow land overgrown with shrubs in 11.4 % and forests in 84.6 %. Lake Bukwald (N 53o58, E 20o 16) is located in the vicinity of the village of Bukwald, municipality of Dywity, around 20 km north of Olsztyn. The lake’s catchment area of 1156.8 ha comprises arable land in 60 %, forests and afforested areas in 31 % and wasteland in the remaining part. The studied water bodies were characterized by low concentrations of the analyzed elements. The average lead and zinc levels reached 28.3 mg/kg d.m. and 32.3 mg/kg d.m., respectively in Lake Ardung, and 33.3 mg/kg d.m. and 91.9 mg/kg d.m., respectively in Lake Bukwald. The total zinc and lead accumulation in the bottom deposits of the investigated water bodies, in terms of the surface area of the lakes and their catchments, was significantly higher in Lake Bukwald than in Lake Ardung.
    Do badań mających na celu określenie wpływu użytkowania zlewni jezior na akumulację ołowiu i cynku w ich osadach dennych wytypowano dwa zbiorniki położone na obszarze Pojezierza Olsztyńskiego. Zlewnie badanych jezior obejmują obszary o zróżnicowanym zagospodarowaniu - od obszarów leśnych po użytki rolne. Jezioro Ardung (N 53o45 , E 20o 55 ) położone jest we wschodniej części Pojezierza Mazurskiego ok. 25 km na wschód od Olsztyna. Powierzchnia jeziora wynosi 26,2 ha, natomiast jego maksymalna głębokość 3,6 m. Na obszarze zlewni jeziora o powierzchni 1539 ha grunty orne stanowią 2 %, łąki i pastwiska 2 %, odłogi w znacznym stopniu zakrzewione 11,4 % i 84,6 % lasy. Jezioro Bukwałd (N 53o58 , E 20o 16 ) położone jest w okolicach wsi Bukwałd w gminie Dywity około 20 km na północ od Olsztyna. Całkowita zlewni jeziora Bukwałd wynosi 1156,8 ha, z czego 60 % stanowią grunty orne, 31 % to lasy i tereny zalesione, pozostałą część stanową nieużytki. Badane osady charakteryzowały się niskim stężeniem badanych pierwiastków i w jeziorze Ardung średnie stężenie Pb wynosiło 28,3 mg Pb/kg s.m., natomiast Zn - 32,3 mg Zn/kg s.m., zaś w jeziorze Bukwałd było to 33,3 mg Pb/kg s.m. oraz 91,1 mg Zn/kg s.m. Także całkowita akumulacja cynku i ołowiu w osadach badanych zbiorników zarówno w odniesieniu do powierzchni lustra wody, jak i zlewni była zdecydowanie większa w osadach jeziora Bukwałd niż śródleśnego jeziora Ardung.
