| Abstract: | Water, sediment and
Biota (plankton, seaweeds, prawn, crabs, gastropods, bivalves and fish) samples
collected from the study region were subjected to analyses of 210Po and 210Pb. It
showed non-uniform distribution of these radionuclides in the biota, in a
descending order: molluscs > crustaceans > fishes. Concentration of 210Po
and 210Pb were 1.65 mBq/l and
3.38 mBq/l in water samples and 4.38 Bq/kg and 2.31 Bq/kg in sediment samples
respectively. Soft tissues and muscle of animals accumulated higher level of 210Po
while shells and bones contained more 210Pb. Bivalve mollusc Perna
viridis accumulated higher levels of both 210Po and 210Pb
thus suggesting that this species can serve as a bioindicator in marine
environment. Concentration factor of 210Po for the biotic components
ranged from ~ 103 to ~104 while for 210Pb it
ranged from ~ 102 to ~ 103. |
