The concentrations of polycyclic aromatic hydrocarbons (PAHs) were determined in 25 surface sediment samples from five sites located at Oludeniz Lagoon of the Turkish Mediterranean coast. The total concentration of the PAHs (1.85 +/- 1.39 mg/kg) was lower than the sediments from highly urbanized areas, while it was comparable with the sediments from similar locations. Acenaphthene and chrysene were dominant ones with the concentrations of 0.620 and 0.515 mg/kg, respectively. The isomeric ratios indicated that combustion is the predominant source of PAHs in the sediments. Factor analysis solution supports the same finding with three major factors accounting for 71.7 % of the variability in the data. Factor 1 with 43.4 % of the total variance identified as a pyrogenic source (coal combustion; 4 rings PAH and traffic related pollution; 5-6 rings PAHs). Factor 2 (explains 39 % of the total variance) represents PAHs originating from traffic, and factor 3 (explains 12 % of the total variance) represents petrogenic source. Our results suggest that combustion of fossil fuels affects most of the points, followed by combustion of biomass and human activity.

Grain size distributions in airborne dust, river-suspended loads, and marine sediments from southeastern Turkey (NE Mediterranean Sea) Ediger, Vedat (2020-01-01) Between February 2001 and January 2002, near the coast of Erdemli, southeastern Turkey, 7 airborne dust samples, 7 coastal river-suspended sediment samples, and 3 marine sediment cores were collected. The main objective of this study was to understand the interrelationships among the multisources, multitransportation paths, and changing depositional conditions around the continental shelf of the Lamas River delta. In addition to a detailed study of satellite photos to track atmospheric dust in the region, g...
Organic nitrogen in rain and aerosol in the eastern Mediterranean atmosphere: An association with atmospheric dust Mace, KA; Kubilay, N; Duce, RA (2003-05-31) From March through early May of 2000, rain and bulk aerosol samples were collected at a coastal site on the eastern Mediterranean Sea at Erdemli, Turkey, and analyzed for nitrogen (N) species, including nitrate (NO3-), nitrite (NO2-), ammonium (NH4+), water-soluble organic N, urea, and dissolved free amino acids. Other ions were also analyzed, including Ca2+, Mg2+, K+, Na+, Cl-, and SO42-. Water-soluble organic N was found to contribute similar to17% and similar to26% of the total water-soluble N in rain an...
Seasonal Changes in the Composition and Abundance ofZooplankton in the Seas of the Mediterranean Basin Kovalev, Av; Mazzocchı, Mg; Toklu Alıçlı, Benin; Skryabın, Va; Kıdeyş, Ahmet Erkan (2003-01-01) Seasonal changes in the composition, abundance and biomass of zooplankton in the seas of the Mediterranean basin (the Mediterranean, Black and Azov seas) have been reviewed using our own data and data from the literature. In the deep-water central regions of the seas, the seasonal cycle of zooplankton abundance is characterised by one maximum occurring in spring or summer. In the coastal regions, two to three peaks (spring, summer and autumn) exist for the zooplankton abundance. The amplitude of seasonal fl...
Zooplankton of the Black Sea and the Eastern Mediterranean Similarities and dissimilarities Kovalev, Av; Mazzocchı, Mg; Sıokoufrangou, I.; Kıdeyş, Ahmet Erkan (2001-01-01) A synthesis of data on abundance and biomass of zooplankton in the Eastern Mediterranean (EMED) and the Black Sea shows major differences in the composition and structure of pelagic communities in the two basins. Few Mediterranean planktonic animals have invaded in the Black Sea. The great bulk of Black Sea species is represented by coastal inhabitants that spread throughout the whole basin. This process has been called “neritization” of the Black Sea fauna. Peculiarities in zooplankton assemblages of the B...
Pah composition of snow samples in Ankara city GAGA, EFTADE EMİNE; Tuncel, G; Tuncel, Süleyman Gürdal (2004-01-01) Surface snow samples were collected in different sites of Ankara in the winter of 2002 to investigate their concentrations of Polycyclic Aromatic Hydrocarbons (PAHs). The collected samples were pre-concentrated by Solid Phase Extraction (SPE) and analyzed by Gas Chromatography-Mass Spectrometry (GC-MS). Extraction procedure and analysis parameters were optimized and a sampling apparatus for collection of surface snow samples was developed. Phenanthrene was found to be dominant at all sites examined. The maj...
