Assessment of Surface Water Quality in the Atikhisar Reservoir and Saricay Creek (Canakkale, Turkey)
(Foundation Environmental Protection & Research-Fepr, 2010) Akbulut, Mehmet; Kaya, Hasan; Celik, Ekrem Sanver; Odabasi, Deniz Anil; Odabasi, Serpil Sagir; Selvi, Kahraman
This study was carried out to evaluate the surface water quality of the Atikhisar Reservoir and Sari ay Creek. Multivariate statistical techniques such as Cluster analysis (CA), principal component analysis (PCA), multidimensional Scaling (MDS), and univariate statistical techniques such as two-way ANOVA were used to analyze the data. Three different groups were formed based on Cluster analysis. Two-way ANOVA test results showed that interaction effects of any variables of the reservoir were non-significant but the interaction effects of pH in the creek were significant. Temperature (T), electrical conductivity (EC), oxygen saturation (OS), biological oxygen demand (BOD), chemical oxygen demand (COD), total phosphate (TP), total nitrate (TN), salinity (Sal), pH, Chl-a, and total suspended solids (TSS) of the reservoir were significantly different among seasons. While differences of T, EC, DO, TP, Chl-a, and TSS of the Sari ay Creek were significant among seasons, only the differences of temperature among the stations were significant. Multi dimensional scaling (MDS) analysis results revealed that the variables such as EC, Sal, OS, T and TN affected the differences among the sites, while the other variable groups were showing a similarity with the COD, BOD, TSS, AD, TP, pH, DO and Chl-a. The principle component analysis (PCA) results showed that the eigenvalues of the first 5 PCA were larger than 1.00, suggesting that they explained 98 % of the total variation.

(2022) Selvi, Kahraman; Kaya, Burcu; Tepeli, Seda Özdikmenli; Kandemir, Gülcan
Bu çalışmada, Çanakkale’nin Yenice ve Bayramiç ilçelerinin demografik özelliklerine göre, su ürünleri tüketimini etkileyen faktörlerin belirlenmesi amaçlanmıştır. Bu kapsamda, 2021 yılının Temmuz ayında basit tesadüfi örnekleme metodu kullanılarak, 320 (160+160) bireye yüz yüze anket uygulanmıştır. Sonuç olarak, her iki ilçedeki katılımcıların, balık fiyatlarının normal olduğunu belirtmesine rağmen, balık eti tüketim tercihinin diğer beyaz et ve kırmızı etten sonra geldiği saptanmıştır. Bununla birlikte balığın sıklıkla taze olarak tercih edildiği ve en çok sağlıklı olduğu için tüketildiği belirlenmiştir. İlçelerdeki balık tüketiminin en fazla sonbahar-kış mevsimlerinde ve ayda 1-3 kg olduğu, katılımcıların balık satın alma yerinin en çok pazar yeri olduğu ve pişirme metodu olarak en çok kızartmayı tercih ettiği belirlenmiştir. Yenice’deki katılımcılara göre (%19,4) yemesinin zor olması, Bayramiç’teki katılımcılara göre (%26,9) ise tadı ve kokusu, balık etinin tercih edilmemesindeki en önemli etken olarak tespit edilmiştir. Buna ilave olarak Yenice ve Bayramiç ilçelerinde tüketicilerin sırasıyla %35 ve %53,8 oranlarında balık haricindeki su ürünlerini tüketmediği tespit edilmiştir. Ayrıca her iki ilçe için en fazla tüketilen deniz balığı türü hamsi, en fazla tüketilen tatlı su balığı türü alabalık olarak belirlenmiştir.
Changing of mollusca fauna in comparison with water quality: Saricay creek and atikhisar reservoir models (Canakkale-Turkey)
(2009) Akbulut, Mehmet; Odabasi, Deniz Anil; Kaya, Hasan; Celik, Ekrem Sanver; Yildirim, M. Zeki; Odabasi, Serpil; Selvi, Kahraman
Species composition, abundance and monthly distribution of the Mollusca fauna and the physicochemical variables of Saricay Creek and Atikhisar Reservoir have been investigated between September 2005-August 2006. Mollusca fauna in Saricay Creek and Atikhisar Reservoir was represented by 21 species of Gastropoda and 8 species of Bivalvia. Diversity, dominance and frequency were recorded monthly. By assessing the data via Shannon-Wiener index, Saricay Creek had an index of 2.58 richness at 8th station while, third station in Atikhisar Reservoir had the poorest with an index of 0.02. According to Bray-Curtis similarity index, the first and third stations were found to be very similar to each other, while 8th and 66 h stations were observed to be the most different from all of the other stations in terms of the dynamics of mollusca fauna. Dreissena polmorpha were the most dominant of 47.16% and frequent species of 48.96%, especially encountered in the Atikhisar Reservoir. The results of One-way Analysis of Similarity (ANOSIM) showed that mollusca compositions were significantly different between sampling sites (p<0.05). ANOSIM and Similarity Percentage analysis (SIMPER) revealed significant differences and a high degree of community dissimilarity within and between the sampling stations. The relationship between the dynamics of organisms and environmental parameters were analyzed using Canonical Correspondence Analysis. This study pointed out that water quality parameters especially COD, BOD, Anionic Detergent, salinity, TP, TN, temperature were effective on the abundance and distribution of Mollusca fauna. © Medwell Journals, 2009.

(Parlar Scientific Publications, 2015) Selvi, Kahraman; Kaya, Hasan; Akbulut, Mehmet; Tulgar, Arinç
The aim of this study was to evaluate some heavy metals concentration (Zn, Pb, Cd, Cu, Fe and Mn) in the water and also in gill, liver, muscle, kidney tissues of European Chub species sampled from Atikhisar Reservoir and Sariçay Creek. As a result of study, it was revealed that the heavy metal levels of the water samples, taken from Sariçay Creek, are statistically higher than the samples, extracted from the Atikhisar Reservoir (p<0.05). All metals, examined within the tissues of the fish from Sariçay Creek were also found out to be statistically higher than the ones from Atikhisar Reservoir (p<0.05). Consequently, this research suggest that the levels of Pb, Cd and Zn, accumulated in the fish samples, which were caught from Sariçay Creek, exceed the limits that are suitable for human consumption. In conclusion, it is estimated that the fish that may be consumed from Sariçay Creek may impair to human health. © by PSP.

(2014) Kaya, Hasan; Akbulut, Mehmet; Selvi, Kahraman; İleri, Burcu; Duysak, Muge
Bu çalışmada su kirliğinin Asellus aquaticus türü üzerinde oluşturabileceği muhtemel oksidatif stres, fizikokimyasal parametreler, su ve canlıda ağır metal birikimi ve canlıda biyomarkırlar birarada kullanılarakdeğerlendirilmiştir. Bu amaçla, bazı bölgeleri evsel ve endüstriyel kirliliğe maruz kalan Sarıçay' dan 3istasyon seçilerek A. aquaticus bireyleri toplanmıştır. Örnekleme istasyonları A. aquaticus bireylerininyaşadığı, fiziko-kimyasal parametreler ve ağır metal içeriği yönünden kirli ve temiz olarak yorumlananbölgelerden seçilmiştir. Toplanan A. aquaticus örneklerinin tür tayini yapıldıktan sonra ağır metal (Cu, Fe,Cd, Pb, Zn) ve biyomarkır (Na+, K+-ATPaz, Glutatyon, TBARS) analizleri yapılmıştır. Yapılan su kaliteanalizlerine göre S3 istasyonu en kirli, S2 istasyonu az kirli ve S1 istasyonu temiz istasyon olarakbelirlenmiştir. Kirliliğin artışına paralel olarak glutatyon (GSH) seviyesinde S2 ve S3 istasyonlarında önemlioranlarda artışlar görülmüştür. Bununla beraber lipid peroksidasyonun göstergesi olan TBARS seviyesi ileNa,K+-ATPase enzim aktivitesinde istatistiksel bir fark belirlenmemiştir. GSH seviyesinin kirli bölgelerdegösterdiği ciddi artışlar (3 kat) su kirliliğinin A. aquaticus türünde oksidatif strese neden olduğunugöstermektedir. Bu sonuçlar, kirliliğe maruz kalan nehirlerde su kirliliğinin belirlenmesi vedeğerlendirilebilmesi için ekolojik, fiziko-kimyasal ve biyokimyasal parametrelerin bir aradakullanılabileceğini göstermektedir.
Heavy Metal Accumulation, Biomarker Responses and Sensitivity to Oxidative Stress in Isopoda Asellus aquaticus from Saricay Creek (Canakkale-Turkey)
(Foundation Environmental Protection & Research-Fepr, 2014) Kaya, Hasan; Akbulut, Mehmet; Selvi, Kahraman; Ileri, Burcu; Duysak, Muge
In this study, the possible oxidative stress that water pollution may cause to Asellus aquaticus is evaluated using the physico-chemical parameters, the heavy metal concentration in the water, and organism and biochemical responses in the living organisms being combined together. For this purpose, the A. aquaticus samples are collected by choosing three stations along the Saricay Creek, some of whose regions are exposed to domestic and industrial pollution. Sampling stations are chosen from regions that are interpreted as polluted or clean according to the heavy metal content and physico-chemical parameters where the A. aquaticus individuals live. After the determination of species is performed, the heavy metal (Cu, Fe, Cd, Pb, and Zn) and biomarker (Na+/K+-ATPase, Glutathione, and TBARS) analyzes were made. According to the water quality analysis, S3 was the most polluted station, S2 was a moderately polluted station, and Si was determined as a clean station. A considerable increase in the amount of glutathione (GSH) was detected in the S2 and S3 stations in parallel with the increase of pollution. However, there were no statistical differences in the TBARS levels as an indicator of lipid peroxidation and Na+/K+-ATPase enzyme activity. The significant increase (three-fold) of the GSH levels in the polluted areas indicates that water pollution causes oxidative stress in the A. aquaticus species. These results show that ecological, physico-chemical, and biochemical parameters can be used together to identify and evaluate the water pollution in rivers that are exposed to pollution.

(CEUR-WS, 2015) Selvi, Kahraman; Kaya, Hasan; Akbulut, Mehmet; Öztekin, Alkan; Çakir, Fikret
This study was conducted in September 2014 to determine the effects of metal accumulation on the Odanata larvae which is a freshwater macroinvertebrate. Polluted area in the lower part of the mine founded on Umurbey Stream (Çanakkale, Turkey) and unpolluted area in the upper part of it are defined as the sampling stations. In this study, GSH (Glutathione), TBARS levels and Na+, K+ -ATPase activity were measured after the determination of metal accumulation (Cd, Cu, Fe, Pb, Zn) in the water and in the Odanata larvae, Ischnura elegans (Vander Linden, 1820). There was a decrease in Na+, K+ - ATPase activity; although the increase in GSH and TBARS levels in organisms sampled from polluted area. These results indicate that; metal accumulation caused to oxidative stress in Odanata larvae I. elegans and this organism reacted by running the compensate mechanisms for it.

(2009) Akbulut, Mehmet; Çelik, Ekrem Şanver; Odabaşi, Deniz Anil; Kaya, Hasan; Selvi, Kahraman; Arslan, Naime; Odabaşi, Serpil S.
Seasonal changes of proportional distribution, biotic indices, abundance, and frequency of benthic macroinvertebrate communities in Menderes Creek were investigated at 5 stations between November 2005 and July 2006. The fauna included a total of 87 taxa belonging principally to Insecta (52 taxa, especially Chironomidae), Oligochaeta (12 taxa), Mollusca (11 taxa), Hirudinae (7 taxa), and Malacostraca (5 taxa). Mean density was estimated to be 778 individuals m-2 for the 87 taxa. Mollusca (38.5%) and Insecta (39.9%) are the dominant groups among the macroin-vertebrate assemblages. Average Shannon-Wiener diversity index was calculated as 1.41, average Margalefs richness index was 1.27, and average Pielou index was 0.61. The results of one-way analysis of similarity (ANOSIM) indicated that macroinvertebrate compositions were significantly different between sampling sites (p> 0.05). ANOSIM and similarity percentage analysis (SIMPER) revealed significant differences and a high degree of community dissimilarity within and between the sampling stations.

Göletin periyodik olarak izlenmesi, çevresel yönetim için yararlı olacaktır.
The use of biomarkers to determine the effects of water pollution on the odonata larvae, Aeshna affinis, in Sariçay Creek (ÇAnakkale- Turkey)
(Parlar Scientific Publications, 2014) Kaya, Hasan; Selvi, Kahraman; Akbulut, Mehmet; Tulgar, Annç
The use of biomarkers in pollution monitoring studies is well-established, but the type of biomarkers which are suitable for use under oxidative stress conditions in this field is not well-known. In this study, biomarker responses to Na+, K+-ATPase, glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) were examined, in the presence of water pollution caused by Aeshna affinis, on odonata larvae collected from Sariçay, some parts of which are subject to domestic, industrial and agricultural pollution. As a result of the study, a significant increase was observed in GSH and TBARS levels in Aeshna affinis individuals collected from the polluted area compared with the living organisms collected from the unpolluted area (p<0.05) whereas a considerable inhibition of Na+, K+-ATPase enzyme activity was discovered (p<0.05). The findings of the study suggest that the polluted area of Sariçay is under oxidative stress from water pollution by Aeshna affinis, which is, however, tolerated by an antioxidant defense system. In addition, the biomarkers used in this study appear to be suitable indicators to see the effects of water pollution on living organisms.
