Item DETERMINATION OF HEAVY METALS IN FISH, WATER AND SEDIMENTS OF AVSAR DAM LAKE IN TURKEYÖztürk, M; Özözen, G; Minareci, O; Minareci, EIn the present study, some heavy metals (Cd, Cr, Cu, Fe, Ni and Pb) were seasonally determined in water, sediment and some tissues of Cyprinus carpio from Avsar Dam Lake, which is an important water source for irrigation and drinking in Turkey. Heavy metal levels in water, sediment and fish samples were analyzed by inductively coupled plasma spectroscopy (ICP/AES). The obtained results showed that the average values of Fe in water samples were higher than the respective reference values for fresh water. Results for levels in water were compared with national and international water quality guidelines, as well as literature data reported for the lakes. The analysis of heavy metals in sediments indicated that among the six heavy metals tested, Fe was maximally accumulated, followed by Ni, Cu, Cr, Pb and Cd. Heavy metal concentrations were found to decrease in sequence of the Cyprinus carpio samples, in the muscle and stomach-intestine as Fe > Cu > Pb > Ni > Cr > Cd; in the gill, heart and liver as Fe > Cu > Ni > Pb > Cr > Cd and in the air sac as Fe > Cu > Ni > Pb > Cd > Cr. In the fish samples, cadmium, chromium, nickel and lead concentrations exceeded the tolerable values provided by international institutions.Item ASSESSMENT OF THE SURFACE WATER QUALITY IN EASTERN MARMARA SEAMinareci, O; Yavuz, M; Cakir, MThe Sea of Marmara is polluted with domestic and industrial wastewater, drainage water from agricultural lands, shipping, and loads carried by streams. Because there are settlement areas where the industry is very concentrated in the Eastern Marmara coastal regions, stations are determined on the coasts of East Marmara. It is aimed to determine water quality in the Eastern Marmara Sea. Parameters of temperature, pH, conductivity, dissolved oxygen, oxygen saturation, turbidity, salinity, anionic detergent, phosphate, ammonium, nitrite, nitrate, boron, total coliform and fecal coliform were determinated. The values were compared with the criteria values specified in the regulations and the values in other studies.Item Antimicrobial Activity of Five Endemic Asperula Species from TurkeyKalyoncu, F; Minareci, E; Minareci, OIn this study, methanol and ether extracts of five endemic Asperula species (Rubiaceae) from Turkey (A. antalyensis, A. brevifolia, A. pseudochlorantha, A. purpurea subsp. apiculata and A. serotina), used in the traditional system of medicine, were tested for antimicrobial activity by the agar well diffusion method and the broth dilution method. The most active species were Asperula brevifolia and A. serotina which showed broad-spectrum antimicrobial activity against Gram-positive and Gram-negative bacteria and maximum inhibition was shown by methanol extract of A. antalyensis against Candida albicans as 32 mm. Methanol extracts of Asperula species were among the most active with the MIC values ranging from 7.6 to 14.8 mg/mL.Item ASSESSMENT OF THE SURFACE WATER QUALITY IN THE KUCUK MENDERES RIVER, TÜRKİYEMinareci, O; Koruk, MThe Kucuk Menderes River is one of the important rivers of the Aegean Region in Turkiye. The river carries agricultural pollution and domestic and industrial wastewater to the Aegean Sea. Therefore, the aim of this study is to determine the parameters of pollution in the Kucuk Menderes River. The parameters of pH, temperature, dissolved oxygen, conductivity, salinity, turbidity, phosphate, ammonium nitrogen, nitrite, nitrate, boron, total coliform and fecal coliform were determined. The average values of these parameters were the followings: pH 9.27, temperature 19.5degree celsius, dissolved oxygen 4.92 mg/L, conductivity 2695 mu s/cm, salinity 0.4 parts per thousand , turbidity 177 mg/L, phosphate 0.17 mg/L, ammonium nitrogen 0.43 mg/L, nitrite nitrogen 0.09 mg/L, nitrate nitrogen 1.73 mg/L, boron 1 mg/L. The values were compared with the criteria values specified in the regulations and those in other studies.Item Ecological quality status of the Turkish coastal waters by using marine macrophytes (macroalgae and angiosperms)Taskin, E; Tan, I; Minareci, E; Minareci, O; Çakir, M; Polat-Beken, ÇMarine macrophytes (macroalgae and angiosperms) were defined as one of the biological quality elements to assess the ecological quality status of transitional and coastal waters by the European Water Framework Directive (WFD, 2000/60/EC). In the present study, the Ecological Evaluation Index (EEI-c) was tested to assess the anthropogenic impact by using marine benthic macrophytes (macroalgae and angiosperms) and pressures by using MA-LUSI in the Turkish marine waters. Macrophyte samples were collected from 56 stations on the coasts of Turkey (at 17 Black Sea, 15 Marmara Sea, 13 Aegean Sea and 11 Mediterranean coastal water bodies) in the summer period between 2014 and 2016. In total, 209 marine macrophytes (macroalgae and angiosperms) taxa were found in all stations. The study revealed high ecological status class for 15 sites, good for 21 sites, moderate for 6 sites, poor for 10 sites, and bad for 4 sites. The MA-LUSI index was tested from the Corine land cover map which affects 1.5 km buffer zone around the sampling sites. The relationship between the pressure index MA-LUSI and EEI-ceqr (eqr: ecological quality ratio) was also tested, and a negative linear relationship was found between MA-LUSI and EEI-ceqr in the Turkish sites. The present study supports the use of the EEI-c index for ecological quality state classification in a wide area of Turkish coastal waters.Item Investigation of Boron Pollution in the Gediz RiverMinareci, OThis study was conducted to determine the concentration of boron in the waters of the Gediz River. According to the results, the boron concentrations ranged from 0.125 to 4.548 mg/L. The average boron value (2.428 mg/L) was compared with Environmental Regulations, Water Pollution Control Regulations and Quality Criteria for Inland Water Resources by Class. The Gediz River was determined as class IV (very polluted) in terms of the boron parameters. It was concluded that the reason for the high boron values were natural and/or industrial discharges at some stations.Item PHYSICOCHEMICAL PARAMETERS OF SEA WATER AT TURKEY COASTSMinareci, O; Taskin, E; Minareci, EIn this study, it is aimed to determine some physico-chemical parameters on the Turkey coasts. pH, temperature, salinity, dissolved oxygen, turbidity, conductivity, phosphate and ammonium nitrogen parameters were determined. The sampling were carried out from 56 points (17 The Black Sea, 15 The Marmara Sea, 13 The Aegean Sea and 11 The Mediterranean), once a year, during the summer-fall period, between 2014-2016. In the Black Sea, mean pH 8.25, temperature 26.53 degrees C, salinity 16.84 parts per thousand, dissolved oxygen 5.45 mg/L, turbidity 2.77 mg/L, conductivity 26574 mu S/cm, phosphate 10.87 mu g/L and ammonium nitrogen 0.046 mg/L; in the Marmara Sea, mean pH 8.18, temperature 25.56 degrees C, salinity 22.27 parts per thousand, dissolved oxygen 5.56 mg/L, turbidity 1.15 mg/L, conductivity 34977 mu S/cm, phosphate 11.14 mu g/L and ammonium nitrogen 0.112 mg/L; in the Aegean Sea, mean pH 8.01, temperature 26.87 degrees C, salinity 35.69 parts per thousand, dissolved oxygen 5.40 mg/L, turbidity 2.08 mg/L, conductivity 53867 mu S/cm, phosphate 9.72 mu g/L and ammonium nitrogen 0.023 mg/L; in the Mediterranean, mean pH 7.87, temperature 28.58 degrees C, salinity 36.01 parts per thousand, dissolved oxygen 4.61 mg/L, turbidity 0.55 mg/L, conductivity 54259 mu S/cm, phosphate 7.90 mu g/L and ammonium nitrogen 0.024 mg/L were found.Item DETERMINATION OF SOME HEAVY METAL CONCENTRATIONS IN WATER AND SEDIMENT SAMPLES TAKEN FROM GEDIZ RIVER (TURKEY)Minareci, O; Ozturk, M; Minareci, EIn this study, heavy metal concentrations of Gediz River were determined between July 2001 and April 2002. Cu, Fe, Mn, Zn, Cd, Co, Cr, Ni and Pb content of water and sediment samples were investigated. The values obtained in this study were compared with permitted maximum heavy metal concentrations for irrigation. All metal concentrations found were low (Cu 0.10, Fe 0.28, Mn 0.19, Zn 1.32, Cd 0.004, Co 0.006, Ni 0.12, Pb 0.22 mg L-1) but chromium (0.12 mg L-1) was at limit concentration at some stations. According to these results, the water is acceptable for irrigation. Furthermore, water sample results were compared with inorganic pollution limit amounts announced by the Water Pollution Control Regulation. It is obvious that the water pollution at Gediz River reached levels threatening public health, because of the high chromium (0.12 mg L-1) and lead (0.22 mg L-1) levels.Item Detergent and phosphate pollution in Gediz River, TurkeyMinareci, O; Öztürk, M; Egemen, Ö; Minareci, EThe Gediz River, located in western Turkey, drains a region with a high population density and a strong economic activity. These factors, together with a lack of facilities for appropriate treatment of domestic and industrial sewage, are putting increasing pressure on water resources. The aim of the present study was to identify point sources of detergent pollution and to assess the surface water quality in the Gediz River by monitoring physicochemical variables. Point sources of wastewater, including some with a high pollution load, were detected in the most populated and industrialized areas of Manisa and Muradiye municipalities. These sources contribute to increasing degradation of water quality observed in the river. Concentrations of anionic detergents and phosphate were 0.084 - 5.592 g m(-3) and 0.0044 - 0.248 g m(-3), respectively. Gediz River is a significant contributor of nutrients to the Aegean Sea.Item THE STUDY OF SURFACE WATER QUALITY IN BUYUK MENDERES RIVER (TURKEY): DETERMINATION OF ANIONIC DETERGENT, PHOSPHATE, BORON AND SOME HEAVY METAL CONTENTSMinareci, O; Cakir, M; Minareci, EThe Buyuk Menderes basin is very wide and the people living here deal with farming, which increases the importance of the river to the region. The pollution of the river increases because the industry, urbanization and agricultural activities are very intense in the river basin. For this reason, the aim of this study is to map the extent of pollution of Buyuk Menderes River, to detect sources causing pollution in the river and also to suggest solutions for taking necessary precautions. Anionic detergent, phosphate, boron and heavy metal concentrations were determined in water samples taken from Buyuk Menderes River in this study. Mean concentrations of anionic detergent, phosphate, boron, copper, chrome, nickel and lead were found 0.2345 mg l(-1), 0.0181 mg l(-1), 0.8352 mg l(-1), 0.0035 mg l(-1), 0.0045 mg l(-1), 0.0247 mg l(-1), 0.0002 mg l(-1), respectively.Item Investigation of Detergent, Phosphate and Boron Pollution in Karacay (Manisa)Minareci, O; Minareci, E; Öztürk, MThe aim of this study is to determine the physico-chemical parameters and anionic detergent, phosphate and boron content of the water samples obtained from Karacay, a tributary of Gediz River. According to analysis results, the anionic detergent concentration 0.071-1.122 mg/L, phosphate concentration 0.002-0.225 mg/L and boron concentration 0.134-3.937 mg/L were found between these amounts. The average values gathered were compared with the Turkish Environmental Legislation, Water Pollution Control Regulation, Quality Criterions According to Classes of Continent Interior Water Sources and Karacay is III. class, namely it is polluted in terms of anionic detergent and it is II. class, namely in the class of less polluted water in terms of phosphate. Boron parameter was found to be IV class over the inorganic pollution limit values in all stations except for a station.Item INCIDENCE OF SEVERE GLUCOSE-6-PHOSPHATE DEHYDROGENASE (G6PD) DEFICIENCY IN COUNTRYSIDE VILLAGES OF THE CENTRAL CITY OF MANISA, TURKEYMinareci, E; Uzunoglu, S; Minareci, OAim: The primary objective of this study was to determine the incidence of severe G6PD deficiency in selected countryside villages of central city of Manisa in Turkey. Secondarily to inform and protect G6PD deficient people from acute hemolytic crisis and neonatal jaundice by delivery of the updated protective food and drug list prepared in the light of the WHO-G6PD Working Committe reports. Methods: In this study, the incidence of severe G6PD deficiency were screened by Beutler's Fluorescence Spot test among 1604 people living in the contryside villages of central city of Manisa in Turkey. Results: Thirty five out of 1604 tested people were found to have severe G6PD deficiency. The incidence of severe G6PD deficiency were 2.2 % in sampled population. There was a difference for the incidence between male (3.2%) and female (1.14%) as expected due to X-linked heritance. There was no significant differences in the prevalence of severe G6PD deficiency between the countryside villages connected to central city of Manisa. Conclusion: The high incidence of severe G6PD deficiency implies that this inherited metabolite disorder is an important health problem in Manisa region and it is necessary to carry out large-scale screening in the whole population since severe-full G6PD deficiency related health problems are preventable. For this reason it must be included in the pool of genetic screening tests in regional health policy.Item Ecological quality status of the Turkish coastal waters by using a marine macrophytic biotic index (EEI-c)Taskin, E; Tan, IBH; Cakir, M; Sungur, O; Minareci, O; Minareci, E; Atabay, HThe present study includes the results of the second benthic macrophytes' monitoring period of a survey of ecological status from the Turkish coasts. The biotic index Ecological Evaluation Index (EEI-c) was used to assess the ecological status classes (ESC) and MA-LUSI the anthropogenic pressures. Sampling was made by the quadrat (20 x 20 cm) method, and the samples were collected from 93 sites in Turkish coastal waters between 2017 and 2019. In total, 240 taxa were found in the Turkish marine waters. Forty sites were classified into High ESC, 24 sites into Good, 12 sites into Moderate, 13 sites into Poor, and 4 sites into Bad ESC. The relationship between the pressure index MA-LUSI and EEIeqr values was also tested, and a negative correlation (R2 = 0.62) was found.
