Size distribution of trace elements and major ions in the eastern Mediterranean atmosphere

2005-10-01
Size distribution of trace elements is measured at the Mediterranean coast of Turkey, by analyzing hi-vol impactor samples collected between August 1993 and May 1994. Mass median diameters of marine elements are between 4.6 and 5.3 mu m, and those of crustal elements are between 3.0 and 3.5 mu m. Mass median diameters of crustal elements are 30% smaller in samples impacted by Saharan Dust. Pollution derived elements, As, Cd, Mo, Pb, Se, and Zn have MMD's between 1.25 and 1.01 mu m. Although 70-90% of the masses of these elements were associated with particles smaller than 2.1 mu m, 10-30% of their mass was associated with coarse particles. Coarse component in concentrations of Cd, Pb, Sb and particulate Hg are due to adsorption of fine anthropogenic particles on coarse crustal aerosol, whereas coarse fraction Zn, As, Se, In, Mo and Au are crustal at Al concentrations > 100 ng m(-3). Bromine, Cr, Ni, and V have bimodal distributions. The fine component, which account for approximately 30-40% of their masses are due to anthropogenic sources, whereas the coarse component, which accounts for 30-50% of their masses are due to sea salt for Br, and crustal particles for Cr, Ni, and V.

Seasonal chemical and mineralogical variability of atmospheric particles in the coastal region of the Northeast Mediterranean
Kubilay, NN; Saydam, AC; Yemenicioglu, S; Kelling, G; Kapur, S; Karaman, C; Akca, E (1997-02-01)
A time-serial analysis of atmospheric particles collected since 1990 at a coastal site bordering the northeastern Mediterranean Sea shows that the collected samples display seasonal patterns in both concentration and color. The 1990-91 and 1992 collections yield an annualised average of around 0.5 g/day dust loading reducing to around 0.3 g/day when the sea-salt contribution is excluded. The highest concentrations of atmospheric particles of continental origin for both natural (e.g. Fe, Mn) and anthropogeni...
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...
Spatio-temporal aerosol trace metal concentrations and sources in the Levantine Basin of the Eastern Mediterranean
Koçak, Mustafa; Kubilay, N; Herut, B (2004-05-01)
The current study considers the spatial and temporal variability in aerosol trace metal concentrations (Al, Fe, Mn, Cr, Cu, Pb, Cd, Zn) in the Levantine Basin of the Eastern Mediterranean, utilising an extensive sample library (n = 621) collected between 1999 and 2001, at two coastal sites located at the northern, Erdemli (Turkey) and southeastern, Tel Shikmona (TS, Israel), region of the Basin. A critical evaluation of the datasets from the two locations was presented. Enhanced concentrations of Al (1.7 x)...
Temporal variations and sources of Eastern Mediterranean aerosols based on a 9-year observation
ÖZTÜRK, FATMA; zararsız, Abdullah; Dutkiewicz, V. A.; Husain, L.; Hopke, P. K.; Tuncel, Süleyman Gürdal (2012-12-01)
Concentrations of 48 elements, NO3-, SO42-, CI-, NH4+ and black carbon (BC) were determined in PM10 aerosols collected daily at a rural Eastern Mediterranean (EM) site (Antalya, 30.34 degrees E, 36.47 degrees N) from 1993 to 2001. Temporal variations (daily, seasonal and long term), sources and source regions of EM aerosols were delineated. Concentrations of elements with marine and crustal origin were more episodic as compared to anthropogenic ones. Most of the variables showed well defined seasonal cycles...
Ionic composition of lower tropospheric aerosols at a Northeastern Mediterranean site: implications regarding sources and long-range transport
Koçak, Mustafa; Mihalopoulos, N (2004-05-01)
Daily bulk aerosol filter samples were collected at Erdemli (36.6degreesN, 34.3degreesE) on the Mediterranean coast of Turkey for a 4-year period between 1996 and 1999. Concentrations of the water-soluble ions (Cl-, Br-, NO3-, SO42-, C2O42- MSA(-), Na+; NH4+, K+, Mg2+ and Ca2+) were measured in a total of 610 samples. In addition, three-dimensional (3-D), 3-day back trajectories of air masses arriving daily at Erdemli were calculated to determine potential aerosol source regions. The results indicated that ...
