Radiological and Chemo-Toxicological Risk Assessment of Naturally Occurred Uranium in Ground Water from Aurangabad District of Maharashtra

Abstract

In the present study, 40 water samples from different locations in Aurangabad districts of Maharashtra state were collected to analyze for Uranium and associated water quality parameters. Uranium was analyzed with the help of LED Flourimeter (Quantalas India Pvt. Ltd) Model no. LF-2a. The uranium concentration in collected water is varying in the range of 0.012 ppb to 16.673 ppb with an average value 2.75ppb and Median is 3.77 ppb. The Average concentration of uranium was calculated with the range 0.0003 Bq/L to 0.417 Bq/L with an average value 0.068 Bq/L and median is 0.025 Bq/L. The calculated cancer risk of mortality was found in the range of 1.270 X 10-8 to 1.7465 X 10-5 with an average value 2.8466 X 10-6, and also the calculated cancer risk of Morbidity was found in the range from 1.9440 X 10-8 to 1.4580 X 10-1 with the mean value 3.6494 X 10-3 respectively. In the calculation of Lifetime Average Daily Dose was found in the range from 0.00034 to 0.47637 μg/kg/Day with an average value 0.07764 μg/kg/Day and median value 0.02834 μg/kg/Day. The calculated Annual Effective Dose due to ingestion of Uranium in drinking water is varying in the range from 0.00680 to 9.44796 μSv/Year with an average value 1.53991μSv/Year and the median value is 0.56207 μSv/ Year
