Investigation of atmospheric deposition of some natural radionuclides and trace elements in Aegean region

Recently, the use of radioisotopes and trace elements in environmental studies is increasing. These radioisotopes and trace elements are emitted from natural and anthropogenic sources in the environment and can remain in the atmospheric, marine and terrestrial environments for many years. Some of these radioisotopes and trace elements directly pollute the environment, while others give important information about the transport of pollutants into the environment. In the study, the annual total depositional fluxes of 210Po, 210Pb, 7Be and trace elements (Li, Be, B, Na, Mg, Al, Si, P, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Mo, Ag, Cd, Sn, Sb, Ba, La, Ce, Tl, Pb and U) have been calculated using data collected from Aliağa, Bornova, and Dikili stations between November 1, 2014 and October 31, 2015. The annual 210Po flux was found as 34.8 Bq m-2 y-1 in Aliağa, 29.2 Bq m-2 y-1 in Bornova, 21.1 Bq m-2 y-1 in Dikili; the annual 210Pb flux was found as 41.7 Bq m-2 y-1 in Aliağa, 43.6 Bq m-2 y-1 in Bornova, 28.6 Bq m-2 y-1 in Dikili; the annual 7Be flux was found as 1391 Bq m-2 y-1 in Aliağa, 1253 Bq m-2 y-1 in Bornova, 1122 Bq m-2 y-1 in Dikili between November 1, 2014 – October 31, 2015.
