galloprovincialis AND Mya arenaria FROM THE
ROMANIAN BLACK SEA SHORE

Abstract
The concentration factors (CF) of three radionuclides
for the marine bivalve molluscs Mytilus galloprovincialis
LAM. and Mya arenaria L. have been determined under 
laboratory conditions. The highest CF for the mussel M.
galloprovincialis (adult) are: for 59 Fe=2,245 (shell)
and 1,41 (soft parts); for 65 Zn=313 and 2,008, respectively.
The highest CF for the soft clam M.arenaria (adult) are: for
59 Fe=303 (shell), 212 (soft parts) and 930 (syphon); for
65 Zn=17,96 and 190, respectively; for 85 Sr=6,6 and 11,
respectively. Both species can be considered as possible
indicator organisms for radioactive contamination by 59 Fe
and 65 Zn in the Black Sea coastal marine environment.
