We study the space-and-time variability of the concentrations of 27 microelements (Sc, Cr, Mn, Fe, Ni,
Co, Cu, Zn, As, Mo, Ag, Cd, Sn, Se, Sb, Ba, La, Ce, Sm, Eu, Tb, Hf, Hg, Pb, Au, Th, and U) and Sr in
the sea, river, and waste waters of the South Coast of Crimea in 2002–2007. Parallel with the data about
elements studied earlier, we present, for the first time, the data of investigations of the contents of rare-
earth elements (Lu, Nd and Yb) whose concentrations in the major part of the analyzed samples of sea-
water were lower than the limit of their quantitative determination. We present the ranges of the concen-
trations of elements and perform their comparison with the data of the previous period of monitoring.
Keywords: neutron-activation analysis, concentration of microelements.
For the first time, the simultaneous investigations of the contents of 27 microelements (Sc, Cr, Mn, Fe, Ni,
Co, Cu, Zn, As, Se, Mo, Ag, Cd, Sn, Sb, Ba, La, Ce, Sm, Eu, Tb, Hf, Au, Hg, Pb, Th, and U) in seawaters of the
South Coast of Crimea were performed by the method of many-element extraction neutron-activation analysis in
the test ranges of the Gurzuf, Yalta, and Simeiz Bays in 1991–2000 [1–7]. In the first period of studies, a trend
of increase in the concentrations was revealed for Cr, Mn, Fe, Co, As, Mo, Sn, Sb, Ba, La, and Hg and the oppo-
site trend was observed for Cu, Zn, Se, Ag, and Pb.
The aim of the present work is to continue the studies of the space-and-time variability of the fields of con-
centrations of the indicated elements by the method of extraction neutron-activation analysis and clarify the
character of this variability in 2002–2007.
Methods and Materials of Investigations
We examined the samples of water taken in the Gurzuf, Yalta and Simeiz test ranges. The schematic map
of location of the sampling stations in 2002–2003 was presented in  and the map of location of the stations in
2004–2007 is shown in Fig. 1.
The samples were taken from the surface and bottom layers at each station (October 17, 18, and 23 in 2002,
December 13 and 17 in 2003, September 9 and 13 in 2004, August 10, 15, and 16 in 2005, August 6 and 7 in
2006, and July 4 and 5 in 2007).
