Statistical analysis and seasonal variation of 210-Leadin the riverine environment of south Karnataka

Discuss the seasonal change of 210Pb in the soil and sediment of the Cauvery River environment in the current study. Using a conventional radiochemical analytical approach, the concentration of 210Pb has been determined from samples taken during the pre-monsoon and monsoon seasons. In monsoon and pre-monsoon, the maximum activity in soil was determined to be 38.34 ± 1.8 Bq kg−1 and 12.82 ±1.12Bq kg−1, respectively. However, the lowest activity was seen during the monsoon (5.63±0.7Bq kg−1) and pre-monsoon (3.07±0.55Bq kg-1). During the monsoon and pre-monsoon seasons, the maximum sediment activity was recorded at 22.5 5 ± 1.4 Bq kg−1 and 12.40±1.10Bq kg−1, respectively. However, during the monsoon and pre-monsoon, the lowest activity was 7.14+0.8Bq kg−1 and 2.97+0.54Bq kg−1, respectively. Compared to before the monsoon, there was significantly more activity during the monsoon.
