<em>Nymphaeion</em> alliance vegetation is dominant floating-leaved vegetation in the Danube–Tisza–Danube hydrosystem in northwestern Serbia and comprises <em>Nymphaeetum albae</em>, <em>Nymphaeetum albo-luteae</em>, <em>Nymphoidetum peltatae</em> and <em>Trapetum natantis</em> associations. Comparative analysis of physical-chemical water parameters on localities where these – in most parts of Europe endangered and vulnerable stands – develop showed that most phytocenoses are associated with specific habitat conditions. Of the analyzed water properties, the factors that cause <em>Nymphaeion</em> alliance phytocenoses differentiation are primarily pH, alkalinity and COD-MnO<sub>4</sub>. Formation of the <em>Nymphaeetum albae</em> stands is significantly associated with the highest values of pH, COD-MnO<sub>4</sub> and alkalinity, and the lowest nitrate, nitrite, dissolved and the total phosphorus content values, in comparison to the other studied associations. <em>Nymphoidetum peltatae</em> stands develop in waters characterized by the lowest pH and COD-MnO<sub>4</sub>, low alkalinity, and the highest nitrate and nitrite values in relation to the other analyzed phytocenoses. <em>Trapetum natantis</em> stands, on the other hand, prefer the warmer sections of the canal network, neutral pH, and the highest values of BOD<sub>5</sub>, dissolved and total phosphorus. Habitat conditions in which <em>Nymphaeetum albo-luteae</em> stands develop are of the widest range in comparison to other investigated phytocenoses.

The objective of the present study was to determine the diversity of phytoplankton and itsrelationship with physical-chemical water parameters of Gampong Pulot Lagoon, Leupungsubdistrict, Aceh Besar. The collecting of phytoplankton and water quality were conducted inDecember 2014. According to field assessment, there were six stations to represent the study site.We recorded 25 species of phytoplankton from class Bacillariophyceae, Dinophyceae andCyanophyceae. The abundance of Bacillariophyceae was 1202.02 ind / L classified as moderate,while Dinophyceae and Cyanophyceae were 621.13 ind / L and 208.49 ind / L, respectively,classified as low abundance. Bacillariophyceae was dominated by Rhizosolenia sp. with 26% ofcomposition. The diversity index has varied from 1,88 to 2,63 indicated as moderate value.  Basedon Principal Component Analysis (PCA) showed that the physical-chemical water parameters relatedto the abundance of phytoplankton in Gampong Pulot Lagoon.Keywords: phytoplankton, lagoon, diversity, leupung

Macrozoobenthos used as a bioindicator of the waters, this happens because of the nature of the benthos which has mpergerakan low so it got a lot of influence from the environment. This study aims to determine the condition of the river Kundur with a view the community structure of macrozoobenthos which include: species composition, abundance, diversity, uniformity and dominance as well as the physical and chemical parameters of water as a paremeter supporters. Based on the results of observations, macrozoobenthos were found during the study in the river Kundur consists of 3 phylum, 4 classes, 17 family with 11 species. The composition of the class of macrozoobenthos in the whole of the observation station consists of a Gastropod (37%), Insecta (23%), Malacostraca (20%), Polychaeta (10%) dan Malacostraca (20%). The value of an abundance ranged from 325,7 - 3309,6 ind/m3. With the value of the total abundance at Station I which is equal to 3690,1 ind/m3, Station II 3723,1 ind/m3, Station III 3692,3 ind/m3 can be categorized diversity are light polluted with the value of the index of uniformity (E) that describes the spread of the individual tends to be uniform or relatively the same. While the condition of the physical-chemical parameters and the substrate bottom of the river Kundur in general has a range of relatively homogeneous, spread evenly throughout the observation stations and still be able to support life macrozoobenthos. To the results of measurements of the parameters of physico-chemical water and substrate in the river kundur in general has a range of relatively homogeneous in the whole observation stations and still be able to support the life of the macrozoobenthos.

This paper aims to reach clear conclusions and conclusions about the importance of management in increasing water quality, monitoring wind, taste and color, and so on. . Studies have been carried out in Radoniq Lake, monitoring physical and chemical parameters as well as heavy metals. Research results have been successful since we have managed to come up with concrete results and conclusions about what it is aimed at. Normally, heavy metals are defined in some locations such as : H-1, H-2, H-3, H-4, H-5 (Fe, Mn, Al, NO 3, NO 2, NH 4+). So the management of water resources has an irrefutable importance in achieving the desired performance on the market, which has also been proven by scientific research, the results of which will appear in some cases exceed international standards.

AbstractWater and sediment chemical compositions were investigated in 75 post-mining lakes in the eastern part of the Muskau Arch region (Western Poland, Central Europe). The lakes, originating from lignite and clay surfaces and underground mining activity, exhibited a wide gradient of physical and chemical water parameters. The most pronounced variability in water parameters was observed in pH values, conductivity, and oxygen concentration in the mixolimnion and monimolimnion. In addition, the lakes varied in terms of their trophic status, indicated by their dissolved organic carbon (DOC) and phosphorous concentrations. In general, lakes with higher pH values had higher trophic states, and some even exhibited hypertrophic conditions. The Monte Carlo test indicated that the water pH, phosphorus, DOC, and silicon concentrations could significantly explain the chemical characteristics of sediments.
