|Title:||Study on the Distribution and Bioaccumulation of Natural Radionuclides, <sup>210</sup>Po and <sup>210</sup>Pb in Parangipettai Coast, South East Coast of India|
<sup>210</sup>Po and <sup>210</sup>Pb
|Abstract:||Water, sediment and Biota (plankton, seaweeds, prawn, crabs, gastropods, bivalves and fish) samples collected from the study region were subjected to analyses of <sup>210</sup>Po and <sup>210</sup>Pb. It showed non-uniform distribution of these radionuclides in the biota, in a descending order: molluscs > crustaceans > fishes. Concentration of <sup>210</sup>Po and <sup>210</sup>Pb 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 <sup>210</sup>Po while shells and bones contained more <sup>210</sup>Pb. Bivalve mollusc <i>Perna viridis</i> accumulated higher levels of both <sup>210</sup>Po and <sup>210</sup>Pb thus suggesting that this species can serve as a bioindicator in marine environment. Concentration factor of <sup>210</sup>Po for the biotic components ranged from ~ 10<sup>3</sup> to ~10<sup>4 </sup>while for <sup>210</sup>Pb it ranged from ~ 10<sup>2</sup> to ~ 10<sup>3</sup>.|
