Özet

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.
