We study the space-and-time variations of the delivery of fluxes of 26 elements (Na, K, Rb, Cs, Cu, Ag,
Au, Ca, Sr, Ba, Zn, Cd, Hg, Hf, Ta, As, Sb, Cr, Se, Mo, W, Mn, Br, Fe, Co and Ni) with atmospheric
precipitations to the sea surface in the regions of Sevastopol and the South Coast of Crimea. It is estab-
lished A series of general regularities of the delivery of the sum of these elements and their soluble and
insoluble forms. We also give the characteristics of their space-time variability.
Keywords: atmospheric precipitations, chemical elements, space-time variability.
The monitoring of the delivery of chemical elements (Na, К, Rb, Cs, Cu, Ag, Au, Ca, Sr, Ba, Zn, Cd, Hg,
Hf, Ta, As, Sb, Cr, Se, Mo, W, Mn, Br, Fe, Co, Ni, Th, U, Sc, La, Ce, Sm, Eu, Tb, Yb, and Lu) with atmos-
pheric precipitations to the sea surface in the region of Sevastopol is carried out since 2004 by applying the neu-
tron-activation and X-ray radiometric analyses. Since 2006, Nd is also detected in addition to the indicated col-
lection of elements. Even the first results  obtained in May–June 2004 demonstrated that the delivery of these
elements leads to the pollution of seawater and the dry land in the region of Sevastopol and that the dependence
of the fluxes of these elements on the time and space coordinates is not monotonic. The ranges of this variabil-
ity were estimated for the first time according to the data of monitoring preformed in 2004–2008 in the region of
Sevastopol and in 2008 near the South Coast of Crimea (SCC) for 11 elements (Th, U, La, Ce, Nd, Sm, Eu, Tb,
Yb, Lu, and Sc). It was shown that the penetration of these elements affects the chemical composition and ra-
diation characteristics of the surface waters in the regions of monitoring , in particular, due to the delivery of
Sm. These results are fairly important for the investiga-
tion of the processes of migration of chemical elements in oceanology, geochemistry, and ecology. This is con-
nected with the regulation of the maximum permissible concentrations of numerous elements from the investi-
gated family in the biosphere. At the same time, the role of the other elements from this family in the biogeo-
chemical cycles of the Black-Sea region is either studied quite poorly or analyzed for the first time.
The aim of the present work is to study the time and space variations of the delivery of Na, К, Rb, Cs, Cu,
Ag, Au, Ca, Sr, Ba, Zn, Cd, Hg, Hf, Ta, As, Sb, Cr, Se, Mo, W, Mn, Br, Fe, Co, and Ni with atmospheric pre-
cipitations to the coastal regions near Sevastopol (2004–2008) and to the South Coast of Crimea (2008).
Material and Methods
The samples of precipitations were taken by using plastic samplers 0.55 m in diameter filled with
mliter of bidistilled water. Each sample was continuously taken for a calendar month. In Sevastopol, the
Marine Department, Ukrainian Scientific-Research Hydrometeorological Institute, Sevastopol, Ukraine.
