This research evaluated the trace metal pollution and the pollution sources in the coastal sediments of Fethiye-Go center dot cek Bay by using the spatial distribution maps, correlation and statistical analysis, which were acquired from 69 sampling points. Spatial distribution maps for eleven elements (namely Al, As, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Ti, V, and Zn) revealed that there is an enrichment of the studied elements, especially near Fethiye harbor. Moreover, the contamination evaluation carried out by using different evaluation methods suggests considerable contamination of As, Co, Cr and Ni. There is a high correlation between Ni, Co, and Fe, Even the minimum Ni concentrations are 9 fold enriched relative to the Earth Crust's values. The controlling factors for element dis-tribution in the area are both natural and anthropogenic. The natural sources are related to the weathering of the geological units and hydrothermal activity. In contrast, various anthropogenic sources include coal smoke, fuel oils used near the crowded harbors, urbanization and the increase in the population recently. When the ecological risk of these enriched elements is considered, the level of probability of toxicity comes out to be the highest, which demonstrates that the accumulation of trace metals in harbor sediments should be considered in the near future to prevent any contamination toward biota and human.

Spatial distribution and source identification of persistent organic pollutants in the sediments of the Yesilirmak River and coastal area in the Black Sea Dinc, Burak; ÇELEBİ, AHMET; Avaz, Gulsen; Canl, Oltan; Guzel, Baris; EREN, BEYTULLAH; Yetiş, Ülkü (2021-11-01) Surface sediments from the Yes,ilirmak River and the near coastal area in the Black Sea were collected using sediment traps to assess the spatial distributions of persistent organic pollutants and find their potential sources. Analyses were carried out to determine the concentrations of the persistent organic pollutants of seventeen polychlorinated dibenzo-p-dioxins and dibenzofurans, sixteen polycyclic aromatic hydrocarbons, seven polychlorinated biphenyls, and eight organochlorine pesticides using high-re...
Investigation of the sediment pollution in Izmir Bay: trace elements Atgin, RS; El-Agha, O; Zararsiz, A; Kocatas, A; PARLAK, HATİCE; Tuncel, Süleyman Gürdal (2000-07-14) The pollution of Izmir Bay was investigated by measuring the trace elements of the surface sediments. The sediment samples were collected from 100 locations in Izmir Bay, five rivers and five sewer outfalls. The collected samples were acid digested and analyzed by flame atomic absorption spectrometry (FAAS), flame atomic emission spectrometry (FAES), graphite furnace atomic absorption spectrometry (GFAAS) and X-ray fluorescence spectrometry (XRF) for a total of 16 trace elements. Selected samples were also ...
Comparison of phosphorus reduction alternatives in control of nutrient concentrations in Lake Uluabat (Bursa, Turkey): Partial versus full sediment dredging YENİLMEZ, Firdes; Aksoy, Ayşegül (2013-01-01) In this study, Water Quality Analysis Simulation Program (WASP) was used to simulate the impacts of various phosphorus (P) load reduction scenarios on nutrient concentrations in Lake Uluabat, a Ramsar site (a wetland of international importance designated under the Ramsar Convention), including sediment dredging options and source reduction. The model was calibrated for various water constituents including ortho-phosphate (PO43-) and nitrate (NO3-). The calibrated model was used as a management tool to pred...
Assessment of temporal variation and sources of PCBs in the sediments of Mediterranean Sea, Mersin Bay, Turkey Gedik, Kadir; İmamoğlu, İpek (Elsevier BV, 2011-01-01) Information on temporal distribution of polychlorinated biphenyls (PCBs) in the coastal sediments of Mediterranean Sea, Mersin was compiled using data published between 1980 and 2009, and the present study. The first congener specific PCB results from the region yield concentration levels of Sigma(41) PCBs in sediments ranging from 0.61 to 1.04 ng g(-1). Sediment profiles show penta-, hexa- and hepta-chlorobiphenyls, specifically, #149 and 153 as the most abundant congeners in all samples. Comparison of tot...
Seismic evidence of shallow gas in the sediment on the shelf off Trabzon, southeastern Black Sea Okyar, M; Ediger, V (1999-04-01) High-resolution seismic surveys carried out on the shelf off Trabzon (southeastern Black Sea) show that the sub-bottom stratigraphy consists of two main depositional sequences (A and B) one of which contains zones of acoustic turbidity. Of these, the upper depositional sequence (A) is thought to comprise Holocene sediments, while the lower depositional sequence (B) is interpreted as approximating to the Pleistocene. The boundary between these sequences is defined by a reflector (R), which is interpreted as ...
