Lake level is one of the most important lake characteristics which allows the results of different effects to be identified and detected. In this work time series of the water levels of Belorussian lakes were analysed in order to detect pattern variations, to evaluate quantitatively the transformation of the hydrological regime of lake ecosystems and to develop prediction models. The possibility of plotting predicting models of lake water levels one year in advance was shown. The complication in plotting predicting models is in its individuality, the huge volume of initial data and the impossibility of immediate assessment of the results. Additional complications are caused by the inhomogeneity of time series of water levels in lakes. Full article

The study focused on the effect of iron and aluminium coagulants (PIX®113, PAX®18) commonly used for purification of open waters on key stages of embryonic development of pike (Esox lucius L.). Fertilized pike roe was incubated in lake water and in water with the admixture of coagulants, applied in the concentration of 50.0 mg dm−3 at selected stages of embryogenesis: blastopore closure, inoculation, and the hatching of larvae. In the course of the experiment, live embryos were observed and total lengths of the larvae were measured. Simultaneously, selected hydrochemical indicators were gauged. It was discovered that coagulants had the strongest effect at the first stage of embryogenesis (the end of the process of gastrulation). At that stage the survival rate of embryos was the lowest (73.5–75.0%) and the percentage of deformities in the hatched larvae was the highest (9.7–10.0%). Full article

This study presents plankton communities (phytoplankton and zooplankton) in the three reservoirs of the River Vistula’s oxbow lake near Zator (Oświęcim Basin). Selected physicochemical parameters of the oxbow lake waters and the bottom sediments were analysed. Aquatic ecosystems in the investigated area have been heterogeneously contaminated with heavy metals (mostly by zinc, cadmium, lead and chromium), because of contaminated waters of the Vistula, and with manganese and iron. The highest differences were observed between Krajskie and Miejsce oxbow lakes among chlorides and the conductivity of the water and among Cr and Fe in the bottom sediments. This indicates a strong influence of the River Vistula. The plankton structure was different in each of the oxbow lakes. The index of taxa similarity showed also differences in the structure of plankton in oxbow lakes, which was convergent with the chemical parameters of oxbow lakes. The index of taxa similarity was similar for all three oxbow lakes only for one group of algae (Chlorophyta) and one group of plankton animals (Rotatoria). Lower similarity was shown between one oxbow lake impacted by the River Vistula (Krajskie) and another oxbow lake completely separated from the River Vistula (Oko). Full article

Biomass and species composition of phytoplankton in relation to the physical and chemical conditions of the water in Lake Adale were studied from March, 2011 to September, 2011. All the physical, chemical and biological parameters measured varied temporally. The temperature of the lake was measured by digital oxygen meter and varied from 22 °C to 26 °C. The chemistry of the lake was basically similar to the dilute East African lake waters, with maximum pH values of 9.2 as measured in situ by a portable digital pH meter. The inorganic nutrients, which were of moderately high levels, varied temporally as a function of hydrological, hydrographic and biological conditions of the lake and were measured by a Hach kit (DR/2000 spectrophotometer) for nitrate, and colorimetrically with the ascorbic acid method for phosphate and molybdosilicate method for silica. The phytoplankton community, which was consistently dominated by cyanobacteria, exhibited low species diversity. Phytoplankton biomass measured as chlorophyll a varied from 23.35 to 55.18 mg m−3 .The concentration of chlorophyll a was calculated according to Talling and Driver (1963) using absorbance measurements made at 665 and 750 nm. The biomass of the lake indicates that the lake is a productive one. The factors responsible for the observed temporal variations in the physical, chemical and biological features of the lake are discussed. Full article

Boron and Manganese Fractions in Dystrophic Lake Waters (Wigry National Park, NE Poland)
by Adam Cudowski, Andrzej Stefan Górniak and Marta Hryniewicka

Abstract
Physicochemical studies in four dystrophic lakes (Suchar Wielki, Suchar II, Suchar IV, and Wądołek) were carried out in Wigry National Park, NE Poland. Total manganese concentrations oscillated within the range of 386.6–647.5 μg Mn dm−3, while those of soluble reactive manganese, [...] Read more.
Physicochemical studies in four dystrophic lakes (Suchar Wielki, Suchar II, Suchar IV, and Wądołek) were carried out in Wigry National Park, NE Poland. Total manganese concentrations oscillated within the range of 386.6–647.5 μg Mn dm−3, while those of soluble reactive manganese, 112.5–328.2 μg Mn dm−3. Fairly high boron contents were recorded in the studied lakes, which amounted to 0.09–2.20 mg B dm−3. The increase in dissolved reactive manganese (DRMn) and decrease in dissolved boron concentration with the lake depth were observed. Almost half (47%) of the total manganese pool was composed of dissolved reactive soluble fraction (DRMn), then dissolved organic form (DOMn, 41%), whereas the particulate fraction (PMn) made up the smallest share (12%). Microbial decomposition of lake organic matter disappears and requirements of authotrophic plankton for Mn2+ decreases when the water temperature drops, thus the fraction prevails. The following regularity was recorded in all analysed dystrophic lakes: iron concentration decreases along with the depth, hence boron content can also be observed due to precipitated borates to bottom sediments, where they are accumulated.

Coagulation behaviour of polyaluminium chloride (PACl) was comparatively investigated in terms of the removal of turbidity and colour with surface water. The growth of flocs was also compared. The results show that the decrease in saturation and values of dissolved oxygen was ca. 20% for ALCAT and PAX 18 at both dosages and 15% for PAX XL 19H, respectively. The floc formation growth indicated that PACl coagulation occurred not only by charge neutralization but also by a form of sweep flocculation. Besides, flocs formed by ALCAT had better sizes than the flocs formed by PAX 18 and PAX XL19H. The rate of sedimentation was stable during coagulation with higher doses, and it was dependent on the substance used. Full article

The paper showed the changes of characteristics of river water flowing through the cascades of reservoirs. One of the cascades is located in a highly urbanized area of Lodz. The second is in a suburban area on the northern outskirts of Lodz agglomeration. However, it still remains under the influence of storm water discharged from the highway. Every 2 weeks, in 4 monitoring points (on the input and on the output of each cascade), the measurements of basic physical and chemical water parameters were made (using data registered in cross-sections obtained between 2006 and 2012). The analysed characteristics can be divided into three groups: 1. No changes in the seasonal fluctuations of analysed characteristics before and after the cascade of reservoirs and no differences between urban and suburban areas in the influence of the cascades on river water; 2. Significant changes in the seasonal fluctuations of analysed characteristics before and after the cascade of reservoirs and no differences between urban and suburban areas in the influence of the cascades on river water; 3. Significant changes in the seasonal fluctuations of analysed characteristics before and after the cascade of reservoirs and also significant differences between urban and suburban areas in the influence of the cascades on river water. The first group includes the temperature and pH of the water, the second group water conductivity and the third group water turbidity and dissolved oxygen in water. Full article
