It has been shown that the Black Sea macrophytes (in particular, multiyear algae
Phyllophora crispa and Cystoseira crinite) and the mollusks (sedentary filter
feeders mussels – Mytilus galloprovincialis) can be the indicated species for
estimation of the radioecological state of coastal water areas. So, radioecologycal
monitoring for successful solve the ecological problems should include the investigation of three aspects: of concentration, migration regularity and dose estimation.
Radiological study the quantitative characteristics of the Black Sea hydrobionts
describing the features of biotic migration of plutonium in the sea-ecosystem may
serve as the basis for assessment of the radioecological situation in the Black Sea
and its forecast for a wide range of concentration activity of plutonium in the sea
water.
Such a comparative analysis with the use of the Polikarpov’s conceptual model
and radioecologycal monitoring observations in natural ecosystems may be applied
for the evaluation and prediction of the environmental situation in the different
aquatic reservoirs.
The developed analytical approaches can serve as a basis for evaluating current
radioecological situation in the Black Sea ecosystems against radionuclides of
plutonium and other radioisotopes. These approaches can be used for prognosis
radioecologycal state of sea area in a wide range of expected concentrations of
radionuclides in the water environment.
The result of research biogeochemical process in the Black Sea ecosystems with
using man-made radionuclides in complex together with natural radioisotopes as
radio tracers of these process and allows us not only receive information about
currently situation in the sea, but investigate regularities of radionuclide behavior in
the Black Sea itself and in Mediterranean basin. This new knowledge of
radioecologycal regularities of migration and redistribution of radioisotopes of
plutonium and quantities parameter of them make possible evaluation of
radioecologycal state of different Black Sea areas and its forecast and make deeper
our understanding of many process of functioning of the sea ecosystems and
mechanisms of these process. It is important not only for radioecology but also
for molismology and hydrobiology in general.
