Sargassum vulgare was sampled by free dives in Iskenderun Bay, Hatay, Turkey, in September 2018. Sargassum vulgare is a material with high economic value because it has compounds that can be used in medical applications such as alginic acid and at the same time it contains carbohydrates and vitamins. Alginates were extracted with a sequential extraction protocol from Sargassum vulgare. Structural characterization of alginate obtained from Sargassum vulgare was determined by FT-IR spectrum, phase structure by XRD diffractometer, and surface morphology by SEM image. Within the scope of the study, alginate obtained from Sargassum vulgare and herbal preservative 705 used in the field of cosmetics were compared. After pretreatment of Sargassum vulgare with ethanol, alginate extraction was performed. Microorganisms of Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, Escherichia coli, Aspergillus brasiliensis were used to examine the antimicrobial activity of the obtained alginate and showed that the contamination risk was tolerable for all microorganisms examined on the seventh day of incubation. Alginate obtained from Sargassum vulgare was found to be more effective than herbal preservative 705 at 0 hours. Pseudomonas aeruginosa, Staphylococcus aureus are microorganisms with the highest effect in the 0 hour. Since alginate obtained from Sargassum vulgare is more effective on microorganisms in a shorter time than herbal preservative 705, it is predicted that it can be a product that can be used in the field of cosmetics.

Occurrence of disinfection by-products in low DOC surface waters in Turkey ATEŞ, Nuray; Kaplan, S. Sule; ŞAHİNKAYA, Erkan; KİTİŞ, Mehmet; Dilek, Filiz Bengü; Yetiş, Ülkü (2007-04-02) A total of 29 surface waters from different regions of Turkey were sampled once a month during 2004. Filtered raw water samples were characterized, chlorinated and the concentrations of disinfection by-products (DBPs) were measured. All waters were low in DOC ranging from 0.91 to 4.42 mg/L. The range of annual average trihalornethanes (THMs) and haloacetic acids (HAAs) concentrations in all waters was 21-189 and 18-149 mu g/L, respectively. Total mass contributions of halides in THMs and HAAs to absorbable ...
Sources and Wet Deposition Fluxes of Polycyclic Aromatic Hydrocarbons (PAHs) in an Urban Site 1000 Meters High in Central Anatolia (Turkey) GAGA, EFTADE EMİNE; Tuncel, Süleyman Gürdal; TUNCEL, SEMRA (2009-01-01) Wet-only precipitation samples were collected using an Andersen wet only sampler (Andersen Samplers, Inc., Atlanta, GA, USA), between December 2000 and June 2002, in Ankara, Turkey. Polycyclic aromatic hydrocarbons (PAHs) were first pre-concentrated using solid phase (SPE) and ultrasonic extraction procedures. They were then analyzed using gas chromatography-mass spectrometry (GC-MS). Phenanthrene (Phe), fluoranthene (Flt), benzo (b+k) fluoranthene (B (b+k) F) and pyrene (Pyr) were the major components of S...
Investigation of short and long term trends in the eastern mediterranean aerosol composition Öztürk, Fatma; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2009) Approximately 2000 daily aerosol samples were collected at Antalya (30°3430.54” E, 36°47’30.54”N) on the Mediterranean coast of Turkey between 1993 and 2001. High volume PM10 sampler was used for the collection of samples on Whatman41 filters. Collected samples were analyzed by a combination of analytical techniques. Energy Dispersive X-Ray Fluorescence (EDXRF) and Inductively Coupled Plasma Mass Spectrometry (ICPMS) was used to measure trace element content of the collected samples from Li to U. Major ions...
Evaluation of site effect within the tectonic basin in the northern side of Ankara Eker, Arif Mert; Kockar, Mustafa Kerem; Akgün, Haluk (2015-06-18) This study mainly concentrates on the determination of site effects for the Plio-Quaternary and especially alluvial soils of the Cubuk district and its close vicinity in Ankara, Turkey. In the study area, particularly in the vicinity of the asymmetric graben that has formed due to the tectonic activities along the NE-SW trending normal faults, a microtremor survey was implemented to identify the local site response under a possible seismic event. The results were compared and correlated by using passive and...
Evaluation of Groundwater Storage changes at Konya Closed Basin Turkey using GRACE based and in situ measurements Yılmaz, Koray Kamil; Yılmaz, Mustafa Tuğrul (null; 2016-04-17) The Konya Closed Basin (KCB) located in Central Anatolia, Turkey, is the primary grain producer in Turkey. The lack of sufficient surface water resources and recently changing crop patterns have led to over-exploitation of groundwater resources and resulted in significant drop in groundwater levels. For this reason monitoring of the groundwater storage change in this region is critical to understand the potential of the current water resources and to devise effective water management strategies to avoid fur...
