Estimation of 210Po and 210Pb and its dose to human beings due to consumption of marine species of Ennore Creek, South India

Estimation of 210Po and 210Pb and its dose to human beings due to consumption of marine species... A systemic study on the natural radionuclides such as 210Po and 210Pb in the environmental matrices and biota of Ennore Creek has been undertaken to establish a baseline data on the radiation profile of Ennore Creek environment. The environmental samples such as water, sediment, and biota (seaweeds, molluscs, crustaceans, and fishes) have been subjected to analyses. It has been observed that the concentration of 210Po and 210Pb in the water samples of Ennore Creek as 2.7 and 1.63 m Bq L−1, respectively. The activity concentration of 210Po and 210Pb in the sediment sample was 17.9 and 28.9 Bq kg−1, respectively. The bivalve mollusk Perna viridis have been identified to accumulate higher concentrations of 210Po and 210Pb suggesting that they could serve as bioindicator of radionuclides in the Ennore Creek environment. The committed effective dose for human beings was found at 81.13–216.8 and 2.1–297.2 μSv year−1 for 210Po and 210Pb, respectively. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Environmental Monitoring and Assessment Springer Journals

Abstract

A systemic study on the natural radionuclides such as 210Po and 210Pb in the environmental matrices and biota of Ennore Creek has been undertaken to establish a baseline data on the radiation profile of Ennore Creek environment. The environmental samples such as water, sediment, and biota (seaweeds, molluscs, crustaceans, and fishes) have been subjected to analyses. It has been observed that the concentration of 210Po and 210Pb in the water samples of Ennore Creek as 2.7 and 1.63 m Bq L−1, respectively. The activity concentration of 210Po and 210Pb in the sediment sample was 17.9 and 28.9 Bq kg−1, respectively. The bivalve mollusk Perna viridis have been identified to accumulate higher concentrations of 210Po and 210Pb suggesting that they could serve as bioindicator of radionuclides in the Ennore Creek environment. The committed effective dose for human beings was found at 81.13–216.8 and 2.1–297.2 μSv year−1 for 210Po and 210Pb, respectively.
