    BACTERIAL COMPOSITION INHABITING WATER COLUMN AND BOTTOM SEDIMENT IN TWO DIFFERENT RUNNING WATER ECOSYSTEMS OF MERIC-ERGENE RIVER BASIN (TURKISH THRACE)
    (Parlar Scientific Publications (P S P), 2017) Mimiroglu, Pinar Altinoluk; Elipek, Belgin Camur
    This study has been carried out to determine the presence and distribution of total heterotrophic bacteria (THB), coliform bacteria (CB), faecal coliform bacteria (FCB) and Escherichia coli bacteria inhabiting different running waters of Meric-Ergene River Basin in Turkey. The highest number of THB bacteria in water body was found in August at a site located in the Ergene River, and the lowest in December at a site located in the Meric (Maritsa, Evros) River. The highest number of THB in sediment was found in February at a site located in the Ergene River, and the lowest in July at a site located in the Meric River. Some physicochemical measurements have been done at the same time as the bacterial sampling to determine environmental conditions of the ecosystems. According to Spearman's correlation index, some environmental conditions were found to have a remarkable correlation with bacterial distribution (p<0.05). This research concluded that pollution load significantly increased bacteria count and played an important role in variation of bacterial quality of the rivers.

    Determination of Snowmelt Water Quality in Outdoor Green Areas: A Case Study at Van Province (Turkey)
    (Istanbul Univ Press, Fac Aquatic Sciences, 2021) Yeler, Okan; Divrik, Menekse Tas; Elipek, Belgin Camur
    Freshwater resources are used for many purposes such as drinking, tap water, industrial usage and agricultural irrigation. Although unpolluted surface waters and groundwater are preferred for the irrigation of landscape plants in parks and gardens, snowmelt water is generally ignored. Like other precipitation types, snow can absorb solid and liquid substances in the atmosphere and it can rain on the earth with its natural chemical structure changed. Also, this water from snowmelt which includes different chemicals can enter surface waters and groundwater resources. In this study, the snowmelt water quality in outdoor green areas of the Van Province was examined. Some physico-chemical features (pH, conductivity, salinity, Ca, Mg, total hardness, Cl, NO3-N, NO2-N, SO4, and PO4) of the snow samples were taken at monthly intervals from six sampling stations between the dates of December 2019 - February 2020. Also, metal ion concentrations (Cd, Pb, As, Cu, Cr, Co, Ni, Zn, Fe, Mn, B, Se, Ba, Al, Na, Be, V, Mo, Si, K, Sr, Ag, Sb, Tl) and the values of SAR (Sodium Adsorption Ratio) and Na% in some sampling stations, which have intense industrial and settlements located in the area, were determined to evaluate the water quality level of the snowmelt water. While, it was observed that some parameters values exceeded the first quality level when compared with the quality levels of the surface water resources control regulation of Turkey and the rates in irrigation water quality values, a general evaluation of the results showed that snowmelt can be alternative irrigation water for plants. Also, the species of the landscape plants in the studied area were identified and the possible effects of the parameters on the development of the plants were discussed.

    DETERMINING OF WATER QUALITY BY USING MULTIVARIATE ANALYSIS TECHNIQUES IN A DRINKING/USING WATER RESERVOIR IN TURKEY
    (Parlar Scientific Publications (P S P), 2017) Elipek, Belgin Camur; Guher, Huseyin; Oterler, Burak; Divrik, Menekse Tas; Mimiroglu, Pinar Altinoluk
    l This study has been carried out to assess the water quality of a drinking/using water reservoir in Turkey by using the different multivariate statistical techniques (Bray-Curtis cluster analysis (BCCA), principle component analysis (PCA), and correspondence analysis (CA) methods). The annual dataset belonging physical and chemical features in the reservoir was obtained by the monthly intervals between the years 2010 and 2011. A total of 15 parameters (temperature, dissolved oxygen (DO), biological oxygen demand (BOD5), light permeability, conductivity, salinity, chloride, pH, total hardness, Ca, Mg, NO2-N, NO3-N, o-PO4, SO4) have been monitored at three different sampling stations in the reservoir and a total of 495 observations were grouped statistically. The sampled periods have been classified into three different groups by using the BCCA. The results were supported by the PCA and CA statistical methods. Consequently, in order to determine and to evaluate for large complex datasets that belong to environmental properties, multivariate analyses are very useful techniques. Thus, the sampling periods to monitor the physicochemical including in a water resource can be determined.

    Influence of Environmental Conditions on the Phytoplankton Community Assemblages in Suloglu Reservoir (Edirne, Turkey)
    (Central Fisheries Research Inst, 2018) Oterler, Burak; Elipek, Belgin Camur; Arat, Salih Murat
    Freshwater resources are some of the most important basic needs necessary for usage by people, especially for drinking water. Reservoirs that are built to store freshwater resources and access water on demand, may be prone to get more environmental effects than natural resources. Phytoplankton, which is the first level of in primary production, is specifically affected by environmental changes in different ways. This study investigated the algal flora of Suloglu Reservoir (Edirne, Turkey) which is utilized as a freshwater reserve, as well as environmental variables influential on its community structure. For this reason a sampling campaign was performed in three stations selected in the reservoir in 3 different depths between January 2013 and November 2013. The study found 111 phytoplanktonic algae taxa belong to the divisions of Chlorophyta, Bacillariphyta, Cyanobacteria, Euglenophyta, Charophyta Miozoa and Ochrophyta. Chlorophyta members were generally dominant, and some environmental factors (i.e. light, pH values, temperature) were significantly effective on the distribution of all algal communities. The Shannon diversity values changed in the range of 1.02-2.75. CCA analysis results showed that there was a noticeable relationship between water quality parameters (chlorophyll-a, pH and water temperature) and time-based changes in dominant phytoplankton species. Moreover, recommendations were provided for sustainable usage of the reservoir whose trophic level was determined.

    Spatial and temporal evaluation of the physicochemical quality of domestic/industrial water in the Kirklareli Reservoir (Turkish Thrace)
    (Serbian Chemical Soc, 2022) Guher, Huseyin; Oterler, Burak; Elipek, Belgin Camur; Yeler, Okan; Aydin, Gazel Burcu
    The Kirklareli Reservoir, located in the Meric-Ergene River Basin, is an important drinking/industrial freshwater resource of the Kirklareli Province. In order to ensure the sustainable use of this important reservoir, its current situation should be examined periodically and evaluated by multivariate analyses. For this reason, water samples were taken between the dates April 2018 and February 2019 at monthly intervals from 3 different stations. The data on the environmental and physicochemical variables (water temperature, dissolved oxygen, pH, salinity, conductivity, total dissolved solids, chlorophyll-alpha, light permeability, fluoride, chloride, NO2-N, NO3-N, PO4, SO4 and essential/potentially toxic elements) were measured and evaluated according to the classes of surface water quality control regulation of Turkey. The parameters exceeding first-class water quality values (chlorophyll-alpha, pH, NO2-N, chloride, selenium) were mapped in GIS using the spline integration approach. In addition, the sodium absorbtion ratio, Kelly index values and magnesium ratio, were calculated to evaluate the water quality for agricultural irrigation water standards. The water quality of the reservoir was evaluated using multivariance analyses (Bray-Curtis similarity index, correspondence analyses, Pearson correlation index). As a result, it was emphasized that the use of the GIS approach is a potential useful method for monitoring the sustainable water quality of the Kirklareli Reservoir, which was determined to have an oligomesotrophic character.

    (Parlar Scientific Publications (P S P), 2016) Aydogdu, Halide; Elipek, Belgin Camur
    The qualitative and quantitative distributions of airborne and waterborne microfungi were determined in the streams at Meric-Ergene River Basin which is one of the biggest wetlands of Turkey. A total of 17 localities at 8 different streams in the basin were sampled in June 2009 and June 2010. While a total of 51 species within 25 microfungi genera were isolated, 37 species of them were observed at water samples and 27 species of them were observed at air samples. Only 12 species of them were found in both sides. The species isolated from the water Alternaria citri, Penicillium citrinum, Cladosporium sphaerospermum, Aspergillus niger and Aspergillus fumigatus were the most abundant ones in the year 2009 (abundance 19.15%, 8.96%, 7.21%, 5.72%, and 4.48%, respectively), and the species Penicillium oxalicum, Cladosporium sphaerospermum, Sarocladium strictum and Davidiella macrocarpa were the most abundant ones in the year 2010 (abundance 1.63%, 1.13%, 1.13%, and 0.75%, respectively). The species isolated from the air Alternaria citri, Graphiopsis chlorocephala, and Cladosporium herbarum were the most abundant ones in the year 2009 (abundance 24.05%, 2.22%, and 2.06% respectively), and the species Fusarium poae, Alternaria citri, and Sarocladium strictum were the most abundant ones in the year 2010 (abundance 34.56%, 7.76%, and 4.35%, respectively). Furthermore, some physicochemical features (air and water temperature, dissolved oxygen, pH, conductivity, light permeability, and bicarbonate) of the sampling localities were measured to determine the relationships between the distributions of the microfungi and environmental conditions.
