- Yüksek Lisans TeziAçık Erişim2025Ergene Meriç Havzası Çorlu Çayı su kalitesinin bakteriyolojik ve fizikokimyasal açıdan değerlendirilmesi
Birce Büyükdumanlı
Bu çalışmada, Ergene Meriç Havzası Çorlu Çayı'nın fizikokimyasal ve bakteriyolojik su kalitesi değerlendirilmiştir. Araştırma, bölgedeki su kaynaklarının kirliliğini inceleyerek, sanayi, tarım ve yerleşim alanlarının bu kirliliğe olan katkılarını ortaya koymayı amaçlamaktadır. İlkbahar ve sonbahar 2024 tarihlerinde beş farklı istasyondan alınan su örnekleri üzerinde yapılan fizikokimyasal analizler, çözünmüş oksijen, pH, sıcaklık, tuzluluk, bulanıklık, kimyasal oksijen ihtiyacı (KOİ), biyolojik oksijen ihtiyacı (BOİ), askıda katı madde (AKM), toplam organik karbon (TOK) ve bakteriyolojik analizler (koliform bakteriler ve E. coli) değerlendirilmiştir. Sonuçlar, özellikle organik kirliliğin yüksek olduğu ve bakteriyolojik kirliliğin kontrol altına alınmadığı bir durumu işaret etmektedir. Mevsimsel analizlerde Nisan 2024 için Çözünmüş oksijen değerinin genel olarak düşük KOİ ve BOİ değerlerinin yüksek olması suyun fekal kaynaklı organik kirlilikle yüklü olduğunu göstermektedir. Kasım 2024 tarihinde istasyonlar bakteriyolojik olarak incelendiğinde; kasım döneminde mevsimsel yağışların olması sebebi ile kısmi bir seyrelme gözlemlenmiştir. Buna bağlı olarak organik parametrelerde ve bakteriyolojik kirlilikte bir miktar azalma olduğu görülmüştür. Ancak AKM ve TOK yüksekliği bakteriyel mevcudiyetin devam ettiğini ve fekal kaynaklı kirliliğin tam olarak ortadan kalkmadığını göstermektedir. Çorlu Deresi bakteriyolojik olarak yüzme veya sulama gibi insan teması kullanımlar için uygun olmadığı, mevcut koşullar suyun organik yükler ve fekal açısından sürekli baskı altında olduğunu ortaya koymaktadır. Bu bulgular ışığında, bölgesel su yönetimi politikalarının güçlendirilmesi, arıtma sistemlerinin modernize edilmesi, tarımsal ve endüstriyel atıkların kontrol altına alınmasının gerekliliği önerilmektedir.

Sadiye Yüce Tavukçu
Bu tez çalışmasında, Ergene Nehri'nin Ulaş, Esenler, Yukarı Sevindikli, Aşağı Sevindikli ve Ballı Hoca istasyonlarında 2024 yılının Nisan ve Kasım dönemlerinde gerçekleştirilen su kalitesi izleme çalışmaları kapsamında fizikokimyasal ve bakteriyolojik parametrelerin mekânsal ve mevsimsel değişimi değerlendirilmiştir. Çalışmanın amacı, nehrin mevcut su kalitesini güncel veriler ışığında ortaya koymak, organik ve mikrobiyolojik kirliliğin boyutunu incelemek ve havza genelindeki kirlilik baskısını bilimsel olarak ortaya koymaktır. Elde edilen bulgular, Ergene Nehri'nin özellikle orta ve aşağı kesimlerinde yoğun kirletici etkiler altında bulunduğunu göstermiştir. Aşağı Sevindikli, Ballı Hoca ve Esenler istasyonlarında ölçülen yüksek KOİ, BOİ, AKM ve bulanıklık değerleri, bu bölgelerin hem noktasal (endüstriyel ve evsel atıksu deşarjları) hem de yayılı (tarımsal faaliyetler ve yüzey akışı) kirlilik kaynaklarının birleşik etkisi altında olduğunu ortaya koymaktadır. Kasım döneminde KOİ ve BOİ değerlerinde belirgin artış gözlenmiş olup bu durum, düşük debi koşullarında azalan seyreltme kapasitesiyle ilişkilendirilmiştir. Bakteriyolojik analizlerde tüm istasyonlarda >100 CFU/mL düzeyinde fekal indikatör bakterilerin tespit edilmesi, Ergene Nehri'nin rekreasyonel kullanım açısından ciddi hijyenik risk taşıdığını ortaya koymuştur. Genel olarak değerlendirildiğinde, Ergene Nehri'nin su kalitesi Yerüstü Su Kalitesi Yönetmeliği (2012) sınıflandırmasına göre büyük ölçüde III. sınıf (kirlenmiş su) seviyesinde bulunmuştur. Bu durum, nehrin hem ekolojik işleyiş hem de halk sağlığı açısından baskı altında olduğunu göstermektedir. Elde edilen bulgular doğrultusunda, havza ölçeğinde kirlilik kontrolünün güçlendirilmesi, ileri arıtma teknolojilerinin yaygınlaştırılması, tarımsal yayılı kaynakların sınırlandırılması ve düzenli izleme çalışmalarının sürdürülmesi önerilmektedir. Çalışma, Ergene Havzası'nın çevresel sürdürülebilirlik açısından kritik bir bölge olduğunu bir kez daha ortaya koymuştur.

Hayrullah Öğedey
Sürdürülebilir çevre koruması için uygun ve finansal olarak uygulanabilir bir arıtma yöntemi belirlemek kritik öneme sahiptir. Çalışmada, Çapakçur Deresi'ne uygulanan elektrokoagülasyon (EK) ile tatlı su salyangozu bazlı biyolojik arıtmayı birleştiren çift aşamalı bir arıtma yaklaşımı değerlendirilmiştir. Elektrokoagülasyon, Viviparus contectus'u içeren ilk aşamanın ardından ikincil arıtma olarak uygulanmıştır. Doğrudan deşarj yönetmeliklerine uymak için, Çapakçur Deresi'ndeki KOİ konsantrasyonunu (204,5 mg L⁻¹) azaltmak için elektrokoagülasyon (EK) kullanılmıştır. Elektrokoagülasyon koşullarının optimizasyonu, akım yoğunluklarının (0,5, 1, 1,5 ve 2 mA cm⁻²), başlangıç pH'ının 5 olması ve 5 ila 20 dakika arasında değişen reaksiyon sürelerinin değerlendirilmesiyle gerçekleştirilmiştir. Arıtma ve işletme giderlerinin değerlendirilmesi, optimum proses parametreleri doğrultusunda gerçekleştirilmiştir. V. contectus tarafından optimum KOİ giderim performansı (%86,71), 20 dakikalık işletme süresiyle pH 5'te gerçekleşmiştir. V. contectus'un alüminyum elektrotlarla optimum koşullar altında 1,25 $/kg COD işletme maliyet etkinliği elde edilmiştir. Sonuç olarak, hibrit bir arıtma prosesi kullanmak atık sudan hem organik hem de inorganik maddelerin uzaklaştırılmasını sağlar.

Pala, Aysegul; Ince, Muharrem; Serdar, Osman
The aim of this study is to test freshwater gammarids as ecotoxicological biomarkers. Gammarids were collected from fresh water and adapted to the laboratory environment. Then, the influence of various variables was investigated. For monitoring and detecting the bioaccumulation level in Gammarus pulex exposed to controlled copper ions and to evaluate potential human and ecological risks, the use of G. pulex as sentinel indicators of water quality is one rational approach. Copper bioaccumulation rate and fate are currently not sufficiently studied. For optimization, the experimental conditions to ensure bioaccumulation level and to find the effects of various variables on proses, a Box–Behnken experimental design was performed. Used mentioned model with statistical underpinnings for Cu2+ ions bioaccumulation have been analyzed, tested and verified and the viability of G. pulex as a biomonitor. The variables’ optimum levels (temperature; 18.1, pH; 4.3, initial concentration of Cu2+ ions, mg L−1; 11.2 and exposure time, h; 42.2) were achieved by employing the quadratic regression model. Critical role of G. pulex in freshwater biomonitoring and their potential to be evaluated as biomarkers for Cu2+ ions was confirmed. It was also explored to see if G. pulex may serve as a potential tool for estimating aquatic quality.

Kutlu, Banu; Sarlgül, Ali
Surface water samples from the area of Munzur Stream in Türkiye (a Ramsar site) were evaluated for their suitability for irrigation and drinking purposes using different water quality indices. The human health risks were assessed as well. The study was conducted over a period of 24 months from January 2019 to December 2021 by taking samples from nine stations every month in order to determine the water quality of Munzur Stream, located in Tunceli. According to the results, Munzur Stream is in good condition in terms of the quality of drinking water and irrigation water. The concentrations of heavy metals such as Cu, Ni, Fe and Hg were high, though the water quality parameter according to Türkiye Ministry of Forestry and Water Affairs Surface Water Quality Regulations (TSWQR) was significantly lower than the permitted limits. In Munzur Stream, the irrigation water for all stations was reported to be excellent, good and suitable in terms of SAR, Na% and MH, respectively. The principal component analysis data formed the four principal components, explaining 98.22% of the total variance. The sources of pollution in this area include the rock types of the basin, soil erosion, domestic waste water discharge and agricultural flow of inorganic fertilisers.

Utku, Anıl; Utku, Esen Damla; Kutlu, Banu
Water, which is very important for life and civilizations on Earth, has been a source of life for all living things. However, freshwater resources gradually decrease due to climate change, pollution, and population growth. Water pollution is the quality changes that occur due to various activities of people, change the chemical, biological, and physical properties of water, restrict or prevent its use, and disrupt ecological balances. The water quality criteria determined to keep this pollution under control ensure the safe use of water. Water quality observations have gained more importance today due to intense environmental concerns and water pollution. This situation revealed the necessity of water quality assessment for water source use. In this study, the CNN-LSTM-based hybrid model was proposed to assess water quality. The proposed model was compared with AdaBoost, DT, GNB, kNN, LGBM, RF, and LSTM according to accuracy, precision, recall, F-score, and AUC. The proposed model has 98.81% accuracy, 99.03% precision, 99.65% recall, 99.33% F-score, and 93% AUC. Practitioner Points: CNN-LSTM hybrid model was developed to water quality assessment. The proposed model is compared with established techniques like AdaBoost, DT, GNB, kNN, LGBM, RF, and LSTM. The developed model has 98.81% classification accuracy. Experimental results show that the developed model will ensure the use of safe water according to water quality criteria.

The European Water Framework Directive (WFD) (2000/60/EC) is the most visionary piece of European environmental legislation that aims to achieve good water status of both surface water and groundwater bodies. The Directive provides a fundamental basis for surface water monitoring activities in the European Member States. The objective of this study is to investigate the occurrence of micropollutants in the Yesilirmak River and to develop a cost-effective monitoring strategy based on spatiotemporal data. A 2-year seasonal monitoring program was conducted between 2016 and 2018, and the water samples were analyzed for 45 priority substances as defined by the WFD and 250 national river basin–specific pollutants. In the basin, 166 pollutants were quantified in at least one of the samples with individual concentrations ranging from 6 × 10−6μg/L to 100 mg/L. Fifty-four pollutants with a frequency of occurrence greater than 5% were selected for further evaluation. Based on statistical evaluation of the data, 20 pollutants were identified as the pollutants of primary concern. These 20 pollutants were grouped under three categories (metals, biocides, and industrial organic compounds) and their spatiotemporal distributions in the basin were assessed to establish a monitoring strategy specific to each pollutant category. The results of the study revealed that the common season for the monitoring of all pollutant categories was the spring. This study provides a generic methodology for the development of a cost-effective water quality monitoring strategy, which can be applicable for use in different basins and pollutant datasets.

Kizak, Volkan; Kapaligoz, Serdar
Goldfish (Carassius auratus) growth was studied comparatively in microgreen aquaponic (APS) and sump filter systems (SFS), and the ef fects of these two different filter systems on water quality parameters were investigated. Arugula (Eruca vesicaria) was used in APS and produced as microgreens. NH3-N, NO2-N, NO3-N, POj and NH4 were measured at specific periods for 60 days. No statistical differences were found between both systems in terms of food conversion ratio (FCR), specific growth rate (SGR), survival and mean body weight of goldfish. In the beginning of the experi-ment, water pH level was around 8.5 while trend towards declining at the end of period. Nitrification process was successful in both systems, and declin ing pH towards from basic medium to approaching neutral levels made positive contribution to perfor mance of nitrifying bacteria. Although there was a significant decrease in the level of NH4, the level of NO3-N increased continously after the 30,h day in APS. According to these results, arugula micro-greens used mostly NH4 instead of NO3-N in higher pH level. Goldfish-arugula microgreen aquaponic system is similar with SFS in terms of keeping water quality in optimal conditions and any adverse effect on goldfish growth and welfare was not ob served in both systems. Although in high pH, it was also seen that arugula seedlings can be produced efficiently as microgreens.

It was assessed the efficiency of the electrocoagulation (EC) in slaughterhouse wastewater (SW) treatment by using antioxidant parameters of Gammarus pulex. The SW was treated by EC. Superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) activities and malondialdehyde (MDA) levels in G. pulex exposed to pre- and post-treated of the SW during 24 h and 96 h were analysed. Standard methods were applied during the analysing process of the physicochemical quality parameters for both untreated and treated SW. All measured physicochemical parameters were decreased following the treatment process via EC. After the treatment process, it was observed that while SOD activities and MDA levels were decreased, CAT activities were increased and GPx activities did not exhibit any change. In conclusion, the present study demonstrated the abilities of untreated SW to promote oxidative stress in model organism. The SOD, CAT activities and MDA levels in G. pulex revealed that EC process were efficient in the SW treatment.

Topal, M.; Arslan Topal, E.I.
In this study, the concentrations of Zn and Cr in downstream waters from Uzunçayir Dam (Tunceli, Turkey) were monitored during spring (March, April, May) and summer (June, July, August) season. Zinc and Cr concentrations in surface water samples were detected using the ICP-MS device. According to the data obtained the lowest Zn and Cr concentrations in the spring season were 65.43±3.2 μg/L in March at 10th day for Zn and 0.28±0.02 μg/L in March at 10th and 20th day for Cr, the highest Zn and Cr concentrations were determined to be 83.12±4.1 μg/L in May at day 30 for Zn and 0.48±0.02 μg/L in May at day 30 for Cr. The lowest Zn and Cr concentrations in summer season were 55.48±2.7 μg/L at 30th day in August for Zn and 0.54±0.03 μg/L at 10th day in June for Cr. The highest Zn and Cr concentration in summer season were found as 69.48±3.5 μg/L in June at day 10 for Zn and 1.23±0.06 μg/L in August at day 30 for Cr. The Zn and Cr concentrations in the downstream of Uzunçayir Dam were found to be smaller than the Zn and Cr concentrations given by the Surface Water Quality Regulation (SWQR). As a result, it was determined that there was no harm in using water from the Uzunçayir Dam as irrigation water or drinking water in terms of Zn and Cr concentrations.

The species of the genus Hirudo are threatened but still used worldwide in human treatment. We studied the density changes of southern medicinal leech Hirudo verbana and some water quality parameters monthly during a year in the Akpinar Marsh, Eastern Anatolia, Turkey. Samples of H. verbana were collected using a modified unit square design and unit time collecting method as an indicator for population density. Some water parameters such as water temperature, dissolved oxygen, pH, some cationic elements (lithium, sodium, ammonium, potassium, magnesium, calcium) and anionic elements (fluoride, chloride, sulphate, nitrate, phosphate, bromide) were determined. These parameters were analysed to detect their impact on population density of this medicinal leech. The populations of H. verbena were most dense in May-June; the species was found in smallest numbers in November and hibernating in December-March. A significant correlation (p<0.05) between the number of medicinal leeches in the unit area and monthly water temperature, amount of ammonium and fluoride was determined using the Pearson correlation coefficient. In the Akpinar Marsh, the largest adult medicinal leeches (>5 g) in the fourth size group formed 12.50-27.50% of the population and the smallest (<1.0 g) in the first size group formed 7.50-38.24%.

Karabas, Necati; Tas, Seyfettin; Erguven, Gokhan Onder; Bayhan, Hurrem
Spatio-temporal variation of the total and fecal coliform groups as bacteriological indicators in the marine environment was investigated in surface water of the Golden Horn Estuary in monthly intervals between June 2012 and May 2013. Temperature, salinity, Secchi depth, pH, dissolved oxygen and oxygen saturation were measured at 10 stations simultaneously with bacteriological analyses. Highest total coliform counts in surface water was 940×103 CFU/100 ml at the Alibeykoy Creek in November and highest fecal coliform was 178×103 CFU/100 ml at the same area in October. The lowest coliform counts were observed during summer, while the highest counts were in autumn. During rainy days, some domestic wastewater overflowing from sewerages are discharged to the estuary, which those water adversely affect water quality. The total and fecal coliform counts in surface water increased gradually from the lower to upper section of the estuary. Although the Black Sea water pumping from the Strait of Istanbul to the Golden Horn by Kagithane Creek is an important factor in the decrease of pollution and better water quality, there are still some runoff materials including uncontrolled discharges particularly in the Alibeykoy Creek. The results of this study showed that that the bacteriological pollution increased due to municipal wastewater resulting from overflow after the precipitation and the surrounding waters of the Golden Horn basin mix with surface waters. Thus, the most important factor in order to decrease the bacteriological pollution is to provide a full control of the surface discharges.

In this study, the preliminary findings obtained from 3 sampling points, which represent the whole, on Maruf Irrigation Dam, which is located in Boyabat district of Sinop province, for 12 months between September 2015 and August 2016 were examined. The parameters monitored are temperature, dissolved oxygen, pH, electrical conductivity, total hardness, total alkalinity, chemical oxygen demand, biological oxygen demand, and dissolved anions and cations (sodium, potassium, calcium, magnesium, ammonium, nitrate, phosphate, chloride, sulfate, and sulfite). Because of its low dissolved ionic matter content, Maruf Dam was characterized as an alkali dam with mid-hard water and low electrical conductivity. In terms of parameters A and B of Surface Water Quality Management Regulation, the dam is considered high-quality and unpolluted. Besides the irrigation purposes, for which the barrage was constructed, the dam can also be used for aquaculture, animal breeding, and farming needs.

In this study, certain water quality parameters (water temperature, dissolved oxygen (DO), pH, total inorganic nitrogen (TIN), phosphate (PO4), nitrite (NO2), nitrate (NO3), ammonium (NH4), and (BOD5) in the effluents and the efficiency of the treatment systems for eliminating wastes at a commercial trout farm with a capacity of 10 tons/year in Izmir (Kemalpasa) were examined. The DO, temperature, pH, TIN, PO4, NO2, NO3, and BOD5 measured, were different in the outlet waters when compared with the inlet waters (p<0.05). The settling basin did not reduce the TIN and PO4, on the contrary, it caused an increase in the nitrogen (N) up to 19.9% and phosphorus (P) up to 20.30%, while the wetlands reduced the N, P, and BOD5 up to 53.2%, 58.2%, and 36.5%, respectively (p<0.05). According to the chemical and biological methods, the averages of the TIN and P loads for one tone of cultured trout without treatment were estimated to be were 80 kg and 7 kg, respectively. The annual TIN load of this trout farm was estimated to be 21.3 kg while the TP load was 2.9 kg for one tone of cultured trout when the treatment efficiency was taken into account. The microbiological analyses conducted with the effluent waters showed that the rate of aerobic mesophilic bacteria was found to be high in the summer but low in the winter. It was also detected that the coliform group bacteria were present in the environment in the summer while their occurence was with-in standards in the winter. Interactions of the 9 water quality parameters were identified through the linear regression analysis in order to reduce the environmental effects of the facility DO=28.296 - (0.248 x BOD5)- (2.948 x pH) + (0.189 x temperature) + (0.851 x inlet water) + (0.163 x winter) (R-2=0.912). According to this model, the DO values were increased by the temperature, inlet water and the winter season while reduced by the BOD5 and pH. The dissolved oxygen content in the wetland outlet water was measured as being high because of the nutrient and temperature rises which boosted photosyntesis. It was concluded that using mechanical settling methods were inadequate to minimise the nutrients released into the receiving water body so wetlands should be constructed in such a way as to receive the flow of effluents from the trout farms. As a result the quality of water used by the facility has no adverse impact on the aquaculture and environmental ecosystem.
