  The effects of the synthetic wastewater on antioxidant defence system in Dreissena polymorpha was evaluated. For this purpose, SOD, CAT, GPX activities and TBARS and GSH levels in tissues were determined by using commercial kits. The activities of SOD and CAT were in sythtetic group were determined lower than the control group in D. polymorpha during 24 and 96 h (p<0.05). After exposure of the cells of D. polymorpha samples to synthetic wastewater, depletion in GSH levels and subsequent increase in TBARS levels were observed, reflecting their unstable state. According to the data obtained from the study, It can be inferred that the biomarkers being domestic monitored are beneficial and effective in evaluating the biochemical mechanisms of wastewater as early warning indicators.

  Sentetik olarak hazırlanmış evsel atıksuyun Phanerochaete chrysosporium ile biyoiyileştirilmesi

  Gözde Ergüven

  Bu çalışma ile P. Chrysosporium beyaz çürükçül mantarı kullanılarak sentetik olarak hazırlanmış evsel atıksudaki kimyasal oksijen ihtiyacı (KOİ), Toplam Organik Karbon (TOK), Toplam Azot (TN), Toplam Fosfor (TP) gibi önemli bazı çevresel parametreler bazında elde edilen giderim verimleri araştırılmış ve Kentsel Atıksu Arıtım Yönetmeliği' ne göre biyoremediasyon sonuçlarının uygun olup olmadığı belirlenmiştir. Çalışma statik 1/1, 1/5 ve Dinamik 1/1, 1/5 seyreltme oranlarında yürütülmüş olup toplmda 11 gün sürmüştür. Çalışma sonucunda en yüksek giderim verimleri 1/5' lik dinamik ortamda KOİ, TOK, TN ve TP için sırasıyla %84, 81, 73 ve 56 olarak bulunurken, en düşük giderim verimleri ise %48, 33, 31 ve 45 olarak statik 1/1' lik ortamda saptanmıştır. Çalışma sonuçlarına göre P. Chrysosporium beyaz çürükçül mantarının sentetik evsel atıksu üzerinde 11 gün gibi makul bir sürede etkin bir biyoremediasyon verimi gerçekleştirdiği ve elde edilen nihai değerlerin de Kentsel Atıksu Arıtım Yönetmeliği' nde belirtilen limit değerlere uygun olduğu gözlemlenmiştir. Bu veriler ışığında, P. chrysosporium beyaz çürükçül mantarının, kenstel atıksuların biyolojik arıtım kademelerinde etkin bir mantar türü olduğu saptanmıştır.

  Erguven, Gokhan Onder; Kanat, Gurdal; Erguven, Gozde

  Water is an indispensable resource for living things to survive. In addition to its direct consumption, water is also used in the preparation of foods necessary for eating and drinking. Therefore, it is extremely important that the water used is drinkable, healthy and safe. The aim of this study is to determine the place of network water as drinking water in consumer preferences. In accordance this purpose, an online questionnaire was prepared with 274 participants from different age groups, including students from Yıldız Technical University (YTU) Department of Environmental Engineering and their relatives and neighbours, including different ages and occupational groups. With this questionnaire, the factors affecting their water preferences and water usage profiles were determined. As a result of the survey, 54.1% of the participants use carboy water, 33.8% use pet bottle water, 12.1% use network water. The criteria that consumers pay attention to in their water preferences are taste, smell, color, cleanliness and the amount of mineral substances in the water, respectively. The reasons for preferring the carboy water, which is preferred by the majority, are that they find the carboy water cleaner and safer and that it tastes better. On the other hand, participants who preferred tap water stated that 33.3% of them preferred this water because its clean and reliable properties, 33.3% of it was affordable and 22.2% of it was easily accessible. When the degree of trust in the network water was questioned, 12.2% of the participants said that they found the network water safe, 40.5% did not find it safe and 47.3% said they were not sure. In addition, when the participants ranked carboy water, pet bottle water and network water according to the degree of reliability, the network water was found to be reliable with a large rate of 89.2%. 35.1% of the respondents stated that they would prefer to drink tap water if the Water Administration periodically discloses their water quality reports and indicates that the network water is clean enough.
