The spatial and species features of heavy metals (Ti, V, Cr, Mn, Ni, Cu, Zn, Zr, Mo, Pb) contents in higher aquatic plants of reservoirs and rivers within Belarus have been analyzed on monitoring data. The group of submerged plants are characterized by high ash content; and they accumulate large amounts of Ti, Mn, Cu, Zn, Zr, Pb. There are statistically signi ficant differences between the plants in ecological groups of reservoirs and rivers in terms of Mn, Cu, Pb contents in the tissues (elements with a 100 % frequency). According to the spatial analysis the reservoirs of the northern geochemical province account for 71 % of the Mn anomalies and 80 % of the Cu anomalies, including the Braslav region – 46 % of the Mn anomalies and 59 % of Cu. Mn, Cu, Pb maximum concentrations are characteristics of submerged macrophytes such lakes as Snudy, Losvido, Maloye Beloye, Beloye (Luninets District), Beloe (Surmino), Svityaz. Among submerged macrophytes within lakes the abnormal accumulation of Mn has been noted for Charophyta (61 % of cases), Myriophyllum and Ceratophyllum, Cu – Charophyta, Isoetes and Lobelia dortmanna, Pb – Isoetes, Charophyta and Potamogeton. The macrophytes within rivers are characterized by the higher ash content and the average content of Mn, Cu and Pb in comparison with the lakes plants. Areas with identified Cu and Pb anomalies in the submerged plants are confined to the central geochemical province of Belarus (the Svisloch river accounts for 67 % of anomalous values of Cu and 33 % of Pb). Anomalous values of Cu have been fixed in the tissues of the Ceratophyllum and Potamogeton, Pb – mostly in Potamogeton. The cluster analysis has distinguished a group of plant species as a part of the following genera: Potamogeton, Myriophyllum, Elodea, Ceratophyllum and Sparganium. The group is characterized by elevated contents of Ti, V, Cr, Mn, Ni, Cu, Zn, Zr, Pb and recommended as indicators of polluting water objects with heavy metals.

This paper deals with pollution of natural and waste waters with heavy metals in the conditions of technogenic impact. It describes one of the numerous methods for neutralizing various contaminants in the aquatic environment, in particular phytoremediation, which has been used for more than 50 years in various countries. The paper considers the role of higher aquatic plants which, according to a variety of confirmatory studies, can be used to extract toxic components from natural and waste water - heavy metal ions. The authors consider a possibility of inorganic origin pollutants extraction with the help of higher water plants of Myriophyllum verticillatum L. and Elodea canadensis Michx. in laboratory conditions. The authors determined pollutants concentration change dependence in the solution with a process duration of less than 10 hours. The authors proved that the maximum purification efficiency is achieved only with the combined use of higher aquatic plants and perfetron. The results of the studies indicate a possibility of water purification from heavy metal ions (ferric iron, bivalent copper, bichromate ions) with the help of higher water plants Myriophyllum verticillatum L. and Elodea canadensis Michx.

Abstract The study was conducted on the Biała Lądecka River which is a mountain river. It is similar to many European mountain rivers in terms of hydromorphology and catchment management. The aim of this study was to determine the bioconcentration factors of heavy metals (Pb, Cd, Hg, Ni, Cr, Cu and Zn) in Ranunculus aquatile (L.) Dumort., Fontinalis antipyretica (L. ex Hedw.), and Lemanea fluviatilis (L.) C.Ag. The content of metals in water, sediment, and submerged plants was determined. The metal concentrations in plants can be arranged as follows: Hg < Cd < Cr < Ni < Cu < Pb <Zn. The highest concentrations of Hg, Ni, Cr, and Cu were observed in F. antipyretica, but the highest concentrations of Pb, Cd, and Zn were in R. aquatile. L. fluviatilis always contained the least amounts of heavy metals. Bioconcentration factors (BCFs) were lowest in L. fluviatilis and highest in F. antipyretica. Among the analyzed metals, plants accumulated the highest amount of Zn, and the least of Hg. The BCFs for Zn were from 24111 (in L. fluviatilis) to 97574 (in R. aquatile), and BCFs for Hg were from 29 (in L. fluviatilis) to 226 (in F. antipyretica).

Ecological Forms

The influence of different species and ecological forms of higher aquatic plants on the abundance, biomass and species diversity of zooplankton was investigated in experimental ecosystems (microcosms). It was shown that in the absence of fish and macroinvertebrate predators, the abundance and diversity of zooplankton in the plants beds increased. Not only phytophilous, littoral, and small planktonic crustaceans, but also some large obligate planktonic crustaceans, reached a high abundance among the plants. Plants belonging to different ecological groups stimulated an increase in the abundance of different groups of zooplankton. In the beds of submerged plants, the number of Cladocera increased to a greater extent than Copepoda or Rotifera. The abundance of Copepoda, both Cyclopoida and Calanoida, grew in the beds of helophytes. The relative number of predators in the community increased among the plants. The species structure and quantitative parameters of zooplankton had their own characteristics in monospecies and mixed phytocenoses of the same plant species. The index of species diversity of zooplankton acquired the highest values in the mixed phytocenosis. Higher aquatic plants increase spatial heterogeneity, which stimulates the development of facultative planktonic and benthic species. The formation of phytogenic detritus and the lifetime release of organic substances by plants into the water causes the development of bacteria and protozoa, which expands the quality and size range of food organisms for zooplankton. Therefore, zooplankton becomes more diverse in terms of the set of trophic groups.

The article examines the species composition of macrophytes (higher aquatic plants) and ichthyofauna of Lake Martyshiv (waterbody of the Osokorky floodplain, eco-corridor of Kyiv). The features of the ecological distribution of higher aquatic plants within the lake Martyshiv are analyzed. The macrophytes are represented by typical limnophilous(lacustrine) complexes. The presence of various groups of macrophytes in the lake indicates a low level of anthropogenic load and is not so differentfrom the values characteristic of a surface water filesunder standard conditions. 22 species of higher aquatic plants have been registered. Phragmites australis (Cav.) Trin. ex Steud., Typha angustifolia L. and Typha latifolia Lare the most common swamping indicator species. Among the studied plants, it should be noted Nuphar lutea (L.) Smith which is protected on the territory of Kyiv in accordance with the decision of the Kyiv Council of December 23, 2004 No. 880/2290. In the ichthyofauna of Lake Martyshiv, 30 species of fish that belong to 9 familieswere identified. In the structure of ichthyocenosis, phytophils (50%) and zoobenthophages (50%) were the dominant ecological groups in terms ofthe method of oviposition and the type of nutrition, respectively. According to the habitat in the reservoir, bottomfishand thicket-livingcategories prevailed (43.3 and 33.3%, respectively). Four species were found in the ichthyofauna of the lake (Rhodeus amarus (Bloch, 1782), Cobitis taenia (sl) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758), Aspius aspius Linnaeus, 1758), which are included to the listof Resolution of the 6thBerne Conventionthat wasadopted to create the Emerald Network. In addition, Carassius carassius Linnaeus, 1758, listed in the Red Book of Ukraine, as well as the elmLeuciscus idus Linnaeus, 1758, which was included in the new edition of the Red Book of Ukraine, were discovered.The research results illustrate preliminary data on the current distribution of species and biological diversity of aquatic ecosystems of the Osokorkyfloodplain. The presence of a number of ecological groups of macrophytes creates a number of biotopes that are important for the existence and reproduction of fish. Thepreservation of LakeMartyshiv in a lesstransformed state providesgroundsforthe creation of a landscape reserve of local importance.Key words:Lake Martyshiv, macrophytes, ichthyofauna, biodiversity, environmental transformation, habitat. У статті розглянуто видовий склад макрофітів (вищі водяні рослини) та іхтіофауни оз. Мартишів (водойма Осокорківської заплави, екокоридору м. Києва). Проаналізовано особливості екологічного розподілу вищих водяних рослин у межах оз. Мартишів. Макрофіти представлені типовими лімнофільними (озерними) комплексами. Наявність різних груп макрофітів у межах озера вказує на низький рівень антропогенного навантаження та мало відрізняється від значень, характерних для масиву поверхневих вод у референційних умовах.Відзначено 22 види вищих водяних рослин. Найпоширеніші види-індикатори процесів заболочення: Phragmitesaustralis(Cav.)Trin. exSteud., Typha angustifolia L. та Typha latifolia L. Серед досліджуваних рослин варто виокремити глечики жовті Nuphar lutea(L.) Smith,які натериторії Києва охороняються на підставі рішенняКиївської міської ради від 23.12.2004 року No880/2290.У складі іхтіофауни оз. Мартишів виявлено 30 видів риб, які належали до 9 родин. У структурі іхтіоценозу за домінуючими екологічними групами за способомвідкладання ікри та типом живлення були фітофіли (50%) та зообентофаги (50%) відповідно. За середовищем існування у водоймі домінували риби придонних та заростевих груп (43,3 та 33,3% відповідно). В іхтіофауні озера було виявлено 4 види (Rhodeus amarus (Bloch, 1782), Cobitis taenia (s.l.) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758), AspiusaspiusLinnaeus, 1758.), які включені до списку Резолюції 6 Бернської конвенції, прийнятої для створення Смарагдової мережі. Крім того, був виявлений CarassiuscarassiusLinnaeus, 1758., що включений до Червоної книги України, а також в’язь Leuciscus idus Linnaeus, 1758, якого буде внесено до нового видання Червоної книги України.Результати досліджень ілюструють попередні дані щодо сучасного розподілу видів та біологічного різноманіття водних екосистем Осокорківської заплави. Наявність низки екологічних груп макрофітів створює низку оселищ, важливих для існування та розмноження риб. Збереження оз. Мартишів у мало трансформованому стані дає підстави для створення ландшафтного заказника.Ключові слова:озеро Мартишів, макрофіти, іхтіофауна, біорізноманіття, трансформація середовища, середовище існування.

<p>The work concerns the occurrence conditions <em>Drosera anglica.</em> (EN) within the site located 10  km  from the village of au nord   Końskie near   the Czarna River. The species is very dispersed but in a few places the density was 5-10 of specimens per 1m<sup>2</sup>. This species grows within a patch which is poor in terms of its flora. No significant expansion of trees or shrubs has been noted. This is related to quite a high level of water. Such conditions are favourable to the development of another species under threat of extinction, <em>Rhynchospora alba. </em>Plant-based patches with participation of sundew are heterogeneous in terms of syntaxonomy.  Presence of species has been observed, e.g. from the classes of <em>Phragmitetea </em>and <em>Scheuchzerio-Caricetea nigrae</em>. Soil analyses indicate that the soils under observation are not very acidic, with average content of CaO and ash content which is optimal for this species with the ratio of C:N which indicates a temporary mire. The content of heavy metals is in norm and poses no threat to the surroundings (Pb 64-65 ppm, Cd 2.7-2.9 ppm). Wide ranges in the analysed samples refer to chromium. They do not have an adverse effect on the development of <em>Drosera anglica</em>. A very crucial threat is the consequence of succession, competition and hydrological conditions.</p>

Metals Accumulation

The spatial variation of trace elements contents of heavy metals (Ti, V, Cr, Mn, Ni, Cu, Pb) in higher aquatic plants of Belarusian lakes has been analyzed according to monitoring data. Natural variability limits of metals contents in aquatic plants of lakes within principal rivers basins of Belarus have been determined. The data on trace elements contents in macrophytes of Belarus are comparable with the data obtained in Poland and other neighbouring countries. Aquatic plants in lakes are characterized by selective metals accumulation, which is different for ecological groups of submersed, emergent and macrophytes with floating leaves. Statistically significant differences between river basins in the contents of Mn, Cu and Pb have been established in the submersed macrophytes. For all ecological groups, the highest concentrations of Mn in lakes macrophytes tissues are observed in the basins of the Dniapro, Prypiać, Zachodni Buh, and the lowest – the Biarezina. The lakes of the Zachodni Buh and Dniapro basins are distinguished by lower Pb concentrations in aquatic plants. Significant differences in the content of Mn and Cu in the plant tissues within different trophicity lakes have been established. The lowest concentrations of Mn are observed in mesotrophic lakes with signs of oligotrophy. Group analysis of lakes based on the content of Mn, Cu, Pb in macrophyte tissues and spatial constraints has been performed. Among the allocated groups are the lakes of the Braslav district characterized by elevated content of Mn and Cu; lakes of the Vilija basin, distinguished by the lowest average levels of Cu and Pb; lakes of the northern part of Belarus, notable for increased contents of Cu and Pb.
