    A survey on drinking water preferences and point of use water treatment systems in Adana, Turkey
    (Desalination Publ, 2020) Aydin, Rozelin; Sirin, Sema
    The World Health Organization (WHO) reports show that the accessibility of improved drinking water in Turkey has improved by 100% since 1990. However because of the threat of water-borne diseases, many still think that it is not wise to drink tap water. This has increased the demand for point-of-use water treatment systems in Turkey. This study aims to assess public preferences on drinking municipal tap water amongst the inhabitants of Adana, Turkey, and to establish the awareness of filter replacement of point of use water treatment systems. 5,139 individuals were interviewed (women 44% and men 56%) and a high percentage of the respondents expressed a preference for using tap water rather than bottled or filtered water. The users of filtered water stated that they preferred the filtration system to remove the pathogens and to change the odor/taste/color of the water. As the age of consumers increased, the bottled and filtered water utilization increased while tap water utilization decreased. In terms of gender, men had a higher ratio to prefer drinking tap water than women. Consumption of tap water decreased as education level and income increased.

    Assessing community awareness for participatory conservation of cultural heritage: the case of Tepebag Tumulus and its surroundings in Adana Turkey
    (Emerald Group Publishing Ltd, 2023) Umar, Nur; Yuceer, Hulya; Aydin, Rozelin
    Purpose The purpose of this paper is to identify the levels of awareness of locals about conservation and cultural heritage, in order to develop suggestions and methods for them to participate in these processes. Design/methodology/approach The method of research is based on face-to-face surveys, mainly questionnaires that were conducted with 1,200 local people. The data obtained was evaluated using the SPSS 25.0.0 V program. Findings The results show that locals mainly find appropriate the assets that reflect their culture but disregard archaeological remains. The participation of locals in the conservation process will end up benefiting them economically. Social implications It is currently accepted that effective conservation cannot be achieved unless its technical considerations are considered together with social and cultural aspects. Ensuring the participation of local people in the conservation process has proved to be important in the development of holistic and sustainable outcomes. In places, where multilayered cultural heritage exists and local residents are from different cultural backgrounds, a detailed assessment of cultural heritage perception that involves local people gains significance. Originality/value It is project-based in the sense of adding the dimension of community awareness to the practice of cultural heritage conservation in the multilayered and multicultural places.

    Evaluation of household water treatment systems in terms of physicochemical and microbiological parameters, Adana Province (Turkey) example
    (Desalination Publ, 2019) Aydin, Rozelin
    Access to safe drinking water is very important in order to protect human health. Although extensive monitoring and controlling of tap water, people state that they do not consume tap water in Turkey. Realization of minor changes in parameters such as odour, colour and taste or misdirected news on the visual media led public to use either bottled water or household water filtration systems. The aim of the present study was to reveal the present situation of contamination in the waters obtained from residential water filtration device by analyzing physical, organoleptic, some chemical and microbiological parameters. Physicochemical properties of taste, colour, odour, turbidity, pH, temperature, conductivity, total hardness, iron, aluminum and nitrate values of 300 samples (inlet and outlet of water) were evaluated. Within the scope of microbiological analysis of Clostridium perfringens, Pseudomonas aeruginosa, coliform, Escherichia coli, colony counting at 22 degrees C and 37 degrees C were examined. The results of the physicochemical analysis showed that tested values stated in the regulation. Microbiological results of samples did not comply with required standards. In particular, E. coli outbreaks showed that water contamination and disinfection procedure were inadequate. According to the paired t test results, we found that E. coli, colonic counts at 22 degrees C and 37 degrees C were statistically significant (p < 0.05). As a conclusion, household water filtration devices cannot demonstrate the performance that they show for chemical pollution when it comes to microbiological contamination.

    Impact of a wastewater treatment plant on microbial community composition and function in a hyporheic zone of a eutrophic river
    (Nature Portfolio, 2015) Atashgahi, Siavash; Aydin, Rozelin; Dimitrov, Mauricio R.; Sipkema, Detmer; Hamonts, Kelly; Lahti, Leo; Maphosa, Farai
    The impact of the installation of a technologically advanced wastewater treatment plant (WWTP) on the benthic microbial community of a vinyl chloride (VC) impacted eutrophic river was examined two years before, and three and four years after installation of the WWTP. Reduced dissolved organic carbon and increased dissolved oxygen concentrations in surface water and reduced total organic carbon and total nitrogen content in the sediment were recorded in the post-WWTP samples. Pyrosequencing of bacterial 16S rRNA gene fragments in sediment cores showed reduced relative abundance of heterotrophs and fermenters such as Chloroflexi and Firmicutes in more oxic and nutrient poor post-WWTP sediments. Similarly, quantitative PCR analysis showed 1-3 orders of magnitude reduction in phylogenetic and functional genes of sulphate reducers, denitrifiers, ammonium oxidizers, methanogens and VC-respiring Dehalococcoides mccartyi. In contrast, members of Proteobacteria adapted to nutrient-poor conditions were enriched in post-WWTP samples. This transition in the trophic state of the hyporheic sediments reduced but did not abolish the VC respiration potential in the post-WWTP sediments as an important hyporheic sediment function. Our results highlight effective nutrient load reduction and parallel microbial ecological state restoration of a human-stressed urban river as a result of installation of a WWTP.

    Impacts of Tourism-Led Constructions on Geoheritage Sites: the Case of Gilindire Cave
    (Springer Heidelberg, 2020) Aydin, Rozelin; Yuceer, Hulya
    Geological heritage sites are of great importance both for better understanding of the formation of the earth and for transferring its memory to future generations. People's curiosity to access this information leads to tourism activity, in which caves constitute a significant place as sources of geotouristic attractions. In the case of Turkey, caves can also be considered as the major source of tourist attractions and thus economic gain providers for local communities. Focusing on the contribution of tourism to the economy, most local authorities allow tourism activity for the caves without adequate research. This leads to the construction of buildings for the needs of visitors and the installation of walking pathways, ladders, and luminaires inside the caves, which are in most cases harmful to cave ecosystems. Located on the Mediterranean coastline of Turkey, Gilindire Cave presents such a case. Unlike other caves in Turkey, it is among three caves that were found to occur in the Cambrian limestone caves literature. Thus, any data to be detected in this environment is of scientific importance. However, service buildings constructed in the upper elevation of the cave and visitor stairs and luminaires installed in the interior constitute major threats to accessing this valuable information. In this context, the study aims to examine the caves in the scope of geotourism and tourism-led constructions through the example of Gilindire Cave. As a result, the study underpins the importance of diligent investigation of cave ecosystems prior to any tourism-led activity and principles for the service structures to be built in such geoheritage sites.

    Sodium lauryl ether sulfate (SLES) degradation by nitrate-reducing bacteria
    (Springer, 2017) Paulo, Ana M. S.; Aydin, Rozelin; Dimitrov, Mauricio R.; Vreeling, Harm; Cavaleiro, Ana J.; Garcia-Encina, Pedro A.; Stams, Alfons J. M.
    The surfactant sodium lauryl ether sulfate (SLES) is widely used in the composition of detergents and frequently ends up in wastewater treatment plants (WWTPs). While aerobic SLES degradation is well studied, little is known about the fate of this compound in anoxic environments, such as denitrification tanks of WWTPs, nor about the bacteria involved in the anoxic biodegradation. Here, we used SLES as sole carbon and energy source, at concentrations ranging from 50 to 1000 mg L-1, to enrich and isolate nitrate-reducing bacteria from activated sludge of a WWTP with the anaerobic-anoxic-oxic (A(2)/O) concept. In the 50 mg L-1 enrichment, Comamonas (50%), Pseudomonas (24%), and Alicycliphilus (12%) were present at higher relative abundance, while Pseudomonas (53%) became dominant in the 1000 mg L-1 enrichment. Aeromonas hydrophila strain S7, Pseudomonas stutzeri strain S8, and Pseudomonas nitroreducens strain S11 were isolated from the enriched cultures. Under denitrifying conditions, strains S8 and S11 degraded 500 mg L-1 SLES in less than 1 day, while strain S7 required more than 6 days. Strains S8 and S11 also showed a remarkable resistance to SLES, being able to grow and reduce nitrate with SLES concentrations up to 40 g L-1. Strain S11 turned out to be the best anoxic SLES degrader, degrading up to 41% of 500 mg L-1. The comparison between SLES anoxic and oxic degradation by strain S11 revealed differences in SLES cleavage, degradation, and sulfate accumulation; both ester and ether cleavage were probably employed in SLES anoxic degradation by strain S11.

    The Ancient City of Anazarbos and Its Significance as a World Heritage Site
    (Springer, 2021) Yuceer, Hulya; Gulsen, F. Fatih; Aydin, Rozelin; Guler, Selen
    The concept of world heritage constitutes an important political, cultural and economic agenda in contemporary society, even though it has been criticized for being Eurocentric. In the case of developing countries such as Turkey, inclusion in the UNESCO World Heritage List helps generate much needed income through grants and tourism activity. There are currently eighteen sites in Turkey that are on the World Heritage List, and another eighty-three on the tentative list, the majority of which have been inscribed in the last decade. However, such an acceleration of attempts to promote sites as world heritage because of their attributes can also lead to conflicts about the values of the sites, project management, community enhancement and the degree to which important related studies are carried out. The ancient city of Anazarbos is one that exemplifies such a situation. The site's history as cultural and military cross-roads in the Cilicia region, and the potential to reveal those who successively inhabited and controlled it paved the way to its inclusion in the tentative list in 2014 by meeting the outstanding universal values. In this context, this study aims to provide an accurate background of in the hope of raising its status so that further research can be carried out. The study first presents the case for the concept of world heritage and then offers a thorough assessment of the city in terms of its heritage significance. Following a discussion on the values associated with the site and the changing dynamics after its inclusion to the list, the study concludes with suggestions for its holistic conservation.
