Opis:: W pracy określono i porównano zawartości azotu i materii organicznej w osadach dennych wybranych rzek zlewni górnej Narwi. Badaniami objęto rzekę Narew w 10 przekrojach pomiarowych oraz rzekę Supraśl, na której wytypowano 6 punktów badawczych. Pobrano także próbki do analiz z 17 mniejszych i większych dopływów Narwi. Azot ogólny oznaczono metodą Kjeldahla, po uprzedniej mineralizacji na mokro w stężonym kwasie siarkowym w obecności 30% H₂O₂. Wyniki badań kształtowały się następująco: azot - od 0,37 do 8,43 g·kg⁻¹ s.m., substancja organiczna - od 0,16% do 27,81%. Zaobserwowano istotną zależność pomiędzy ilością materii organicznej a zawartością azotu w osadach dennych badanych rzek.
The study defined and compared the contents of nitrogen and organic matter in bottom sediments of selected rivers from upper Narew basin. Investigations comprised 10 measuring points of Narew river and 6 points of the Supraśl river. Samples were also taken from 17 smaller and bigger tributaries of the Narew river. After mineralization in concentrated H₂SO₄ at the presence of 30% H₂O₂, total nitrogen was determined by Kjeldahl method. The results of investigations were: nitrogen - from 0.37 to 8.43 g·kg⁻¹ DM, organic matter - from 0.16% to 27.81%. Investigations showed a significant relationship between the quantity of organic matter and nitrogen content in bottom sediments from the rivers under study.

Opis:: Aquatic ecosystems are a valuable part of natural environment. The increasing level of pollution in waters transforming biocoenoses and other adverse effects of the impact of toxic substances have contributed to the development of biological monitoring. The aim of the study was to determine the changes in contents of zinc and lead in bottom sediments and roots of aquatic plants: Phragmites australis and Acorus calamus in the river Narew. There were 14 points on the river, from where samples of bottom sediments and plant material were collected. The contents of lead and zinc were determined by means of flame atomic absorption spectrophotometry using Varian device. It was proven that bottom sediments were characterized by low contents of zinc and lead except from two sampling points: in Bondary and Narew. Achieved results of analyzes of plant material showed a slight exceeding in the case of lead. Spatial distribution of zinc and lead contents in examined roots of plants coincided with their contents in bottom sediments, which was also confirmed by statistical analysis. It was proven that aquatic plants had greater tendency for accumulation of metals than bottom sediments.

Opis:: The study dealt with the bottom sediments from the Narew River in the section Bondary-Tykocin 18 tributaries in the catchment of the upper Narew. Samples were collected in summer (August) and autumn (October) 2005 from the surface layer of bottom sediments in the shore zone. Determinations of organic carbon were performed on a TOC 1200 analyzer (Thermo Euroglas). The bottom sediments collected from the upper Narew contained less organic carbon, which resulted from intensive mineralization. Sediments from the small rivers were most abundant in organic carbon. These rivers are characterized by a low flow rate and, in most cases, they are overgrown by water plants. The organic carbon contents were highly varied between the sampling points. Positive linear correlation was found between combustion loss and organic carbon content.
Badaniami objęto osady denne z rzeki Narew na odcinku Bondary-Tykocin oraz 18 jej dopływów w obrębie zlewni górnej Narwi. Próbki pobrano latem (sierpień) i jesienią (październik) 2005 r. z powierzchniowej warstwy osadu dennego w strefie brzegowej. Węgiel organiczny oznaczano na analizatorze TOC 1200 firmy Thermo Euroglas. Osady denne pobrane z rzeki Narew zawierały mniej węgla organicznego - jest to wynik intensywnej mineralizacji. Najzasobniejsze w węgiel organiczny były osady denne małych rzek. Rzeki te mają małe prędkości przepływu, w większości przypadków są porośnięte roślinnością wodną. Zawartość węgla organicznego wykazała dużą zmienność w zależności od lokalizacji punktów poboru próbek. Stwierdzono dodatnią korelację liniową między zawartością straty prażenia a węglem organicznym.

Opis:: Creating the buffer zones is a function intended to designate an area in particular, of a constant distance around the spatial objects. The aim of the study was to create maps as thematic layers, which served to identify areas of existing and potential contamination of surface water and other environmental elements. Among others, it made possible to localize the areas potentially affected by the surface water pollution due to transport; localize the areas potentially affected by the surface water pollution due to the discharge of sewage from human settlements; localize the zones with mitigated impact of communication emissions due to the natural protection of forests taking the form of so-called geochemical barriers. The spatial analyzes allowed to generate model-zones of the existing and potential threat of water pollution in the Narew river catchment. Designated danger zones can be verified by studies as well as they can be very helpful in determining the monitoring network and for water quality modeling process.

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 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 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 main purpose of the study was to evaluate water quality of the Supraśl river and identify its main pollution sources. On the river and its tributaries, 8 control points were selected, located near Krynica, Gródek, Nowosiółki, Zasady (mouth of the tributary Sokołda), Supraśl, Nowodworce, Dobrzyniewo (mouth of the tributary Biała) and Dzikie. The control points were selected in such a way as to take into account the impact of major point sources of analyzed components located along the river and its main tributaries on water quality in the main stream catchment. Water samples were collected once a month during the period from May to November in 2014. In water samples the concentration of dissolved oxygen, Cl^-, SO₄^2-, N-NH₄⁺, P-PO₄^3- and the values of pH, BOD₅ and electrolytic conductivity were indicated. Based on the obtained results, loads of the individual components in river waters were calculated as a product of concentration and Supraśl waters flow rate in a particular month. Supraśl waters, due to values of most analyzed parameters, should be classified as first quality class. The source of Cl^-, SO₄^2-, N-NH₄⁺ in Supraśl waters were treated wastewater and other anthropogenic sources associated with the basin development. Reduced Supraśl water quality is caused by the inflow of organic substances expressed by BZT₅ from natural and anthropogenic origin and concentration of PO₄^3-, which were mainly delivered with treated wastewater.
