AbstractThe aim of this study was to examine the community structure and vertical micro-distribution of psammonic ciliates in two lakes of different trophic status in eastern Poland. Additionally, the size and trophic structure of these microorganisms, and the influence of physical and chemical water parameters on their abundance, were analysed. Psammon samples were collected during spring, summer, and autumn of 2010. In each of the lakes samples were collected in the euarenal, higroarenal, and hydroarenal zones of the psammolittoral. In order to determine the micro-vertical distribution of ciliates, each sample was divided into two sub-samples: the upper part (0–1cm) and the lower part (1–2cm). The species diversity of ciliates decreased with depth. The tendency was particularly clear in mesotrophic lakes. Irrespective of the lake’s trophic type and arenal zones, significantly higher numbers and biomass of ciliates were recorded in the surface layer of the psammolittoral. The upper layer of sand was dominated by omnivorous taxa, whereas the deeper layer showed increases in the proportions of bacterivore species. The factors limiting the occurrence of ciliates are mainly concentrations of total organic carbon and nutrients.

Horizontal Distribution of Psammonic Ciliates in Two Lakes of Different Trophic Status: Relationship to Physical and Chemical ParametersThe aims of this study were to identify the taxonomic diversity and abundance of psammonic ciliate communities in mesotrophic and eutrophic lakes (Łęczna-Włodawa Lakeland, eastern Poland). The effect of selected physical and chemical water parameters on ciliates community was also analysed. Psammon samples were collected during three seasons: spring, summer and autumn of 2010. In each lake, in the psammolittoral, samples were collected in the euarenal, higroarenal, and hydroarenal zones. A total of 53 ciliate taxa were recorded. The highest value of the Shannon-Weaver index was recorded in summer in eutrophic lake (2.79). At the same time in mesotrophic lake, a lower value of the index was determined (0.79). The mean numbers of ciliates ranged from 516 ind.cm-3in the eutrophic lake to 191 ind. cm-3in the mesotrophic lake. In eutrophic lake, the highest number of ciliates was recorded in the euarenal (649 ind. cm-3), and the lowest in the higroarenal (425 ind. cm-3). In the mesotrophic lake, the highest average numbers were determined in the higroarenal (235 ind. cm-3), and the lowest in the hydroarenal (155 ind. cm-3). Irrespective of the lake trophy, Hymenostomata (Paramecium sp., Glaucoma sp., Uronema nigricans) occurred in the highest numbers (from 13 to 95%). The results demonstrated that N-NH4, P-PO4and TOC can strongly regulate the abundance and taxonomic composition of ciliates. The strongest correlations between numbers of ciliates and physical and chemical water parameters were observed in the higro- and hydroarenal zones of the eutrophic lake.

This study focuses on the different physical and chemical water quality parameters of two catchment areas centring on the extent of water pollution in the two basins. Data containing physical and chemical water quality parameters for the Crocodile (West) Catchment area (Gauteng) and the Berg Catchment area (Western Cape) at reconnaissance level of detail were collected from the Department of Water Affairs (DWA) over a period of 5 years, 2007–2011. The relevant data were screened and sorted using the SPSS Software Version 2.0. The data were subjected to ANOVA statistics to search for significant variations in the water quality parameters of concern across the study period in each of the catchment area. The physical and chemical analyses were carried out to determine whether the water quality falls within the total water quality range as prescribed by DWA and WHO for domestic use. Pearson correlation analyses were used to determine the relationship between physical and chemical water quality parameters and the rainfall data over the study period.

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.

Peat soil is a type of soil that is formed from the accumulation of plant debris which undergoes a decomposition process. This is why peat soil contains high organic matter and is acidic. Peat soils will affect the parameters of a surrounding aquatic ecosystem, such as the Rasau peat swamp ecosystem in the village of Rantau Panjang. Peat swamp water parameters are influenced by substances stored in the peat such as having a low pH, high heavy metal content, and having high TSS, TDS, BOD and COD values. The water parameter of peat swamp with mangrove vegetation is better than that of peat swamp that does not have mangrove vegetation. This can be seen if the peat swamp water parameters are laboratory tested. The physical parameters of water, namely temperature, TDS, DHL, color, and turbidity were lower in the Rasau peat swamp with mangrove vegetation compared to the non-vegetated ones. The chemical parameters of the Rasau peat swamp with high density mangrove vegetation such as higher pH, and lower BOD, COD, and iron (Fe) when compared to peat swamps without mangrove vegetation. However, the physical and chemical parameters of vegetated and non-vegetated peat swamps are still above the PPRI No. 82 of 2001.

Objectives: Urinary schistosomiasis is known to be endemic in the lake Nokoué areas of the District of So-Ava. For the past ten years, the National Control Programme for Communicable Diseases of the Ministry of Health has been making efforts to control schistosomiaisis morbidity through mass drug treatment with Praziquantel. This study aimed to assess the diversity and dynamic of potential snails known as schistosomiasis intermediate hosts. Methodology and Results: This study was carried out for 12 months (from July 2015 to June 2016) and consisted in the periodical analysis of the physical and chemical water parameters (temperature, oxygen concentration, pH, nitrite and nitrate rates. Salinity, total dissolved solids (TDS) and, biochemical oxygen demand) in relation with diversity, distribution and relative abundance of freshwater snails (Bulinus forskalii, B. globosus and B. truncatus). To this end, seven harvesting sites on Lake Nokoué were, reasonably selected for monthly hydrobiological and malacological data monitoring. The results showed a variable correlation between the dynamic of schistosomiasis intermediate host snailsm and several physico-chemical water parameters. Bulinus globosus was negatively influenced by salinity and nitrate rates while B. forskalii was negatively influenced by pH, Oxygen, TDS, salinity and nitrate rates. The three species of freshwater snails were strongly influenced by the water temperature. Conclusion: The results suggest a seasonal schistosome transmission induced by the seasonal dynamic of intermediate host snails. Water quality seems appropriate to the development of host snails from December to March and would be the strong period of schistosomiasis transmission. However, furthermore studies will need for well understanding the dynamic transmission necessary for developing adapted strategy control.

This study was undertaken by analyzing data from satellite image (Landsat-8 OLI) and geographical information system (GIS) to find the relationship between water parameters and water indices of spectral images. The main purpose of this research was to develop a model for the physical and chemical parameters of Gharraf stream in Iraq. The water  parameters used in this study included: acidity (PH), Total Dissolved Solids (T.D.S),  Alkalinity(ALK), Electrical Conductivity (E.C), Calcium(Ca), Chloride (CL), Sodium (Na), Sulfate (SO4), Potassium (k), Total suspended solid (T.S.S), Total Hardness (TH).Where the samples were taken to seventeen stations with two seasons and at the same time took a satellite image on 4/FEB, 11 / MAY.GIS techniques were used in the beginning to project the coordinates of seventeen stations along the stream in Landsat-8 satellite image for extract data. Then, these data are treated in SPSS software for purpose finding correlation and regression equations. Positive strong correlations between the reflectance of the satellite image and the water parameters in 4/FEB and 11/ MAY with five stations, helped to build six regression models. These models could be used to predict these six water parameters (PH, E.c, CL, SO4, Na and K) at any point along the stream in Iraq from the satellite image directly.
