Abstract

The paper discusses the speciation and behavior of 210Po and210Pb in the soil and sediment samples in the Cauvery River environment. The samples were collected and the concentration of 210Po and 210Pb was measured using the standard radiochemical analytical method. The physicochemical parameters of the soil and sediment were studied to understand the dynamics of 210Po and 210Pb activity in the riverine environment. The dependence of the physicochemical parameters like clay and organic matter content on the speciation of 210Po and 210Pb in the riverine ecosystems were also studied. The mean activity of 210Po and 210Pb in soil was found to be 6.80 and 6.58 Bq kg–1, respectively. The mean activity of 210Po and 210Pb in the sediment was found to be 3.30 and 6.34 Bq kg–1, respectively. The activities of 210Po and 210Pb in both the soil and sediment are not in equilibrium. The activity concentrations of 210Po and 210Pb were correlated with the organic matter content in both the soil and sediment samples. Multivariate statistical analysis was used to confirm the interrelation between the physicochemical parameters and the activity of 210Po and 210Pb.
