Abstract |
|
In the present study, the groundwater samples from 30 locations in Mahendragarh district of Haryana state were collected and analyzed for uranium concentration using L.E.D Fluorimeter Quantalase LF-2a. This fluorimeter can measure uranium concentration in water samples from 0.5 μg/L to 1000 μg/L with an accuracy of +/- 10% or 0.05 ppb whichever is greater and repeatability of better than +/- 5%. The uranium conc. Was found to be varying in a range of 0.56 – 57.53 μg/L with the mean value of 18.87 μg/L. The cancer risk for mortality and morbidity was calculated and found to be in the range from 5.89 x 10-7 – 6.03 x 10-5 with the mean value of 1.98 x 10-5 and in the range from 9.11 x 10-7 – 9.32 x 10-5 with the mean value of 3.06 x 10-5 respectively. Chemical toxicity risk, which is also expressed as Lifetime Average Daily Dose (LADD) value was also calculated and found to be varying in a range of 0.01 – 1.13 μg/kg/Day with the mean value of 0.37 μg/kg/Day. Annual Effective Dose due to ingestion was found to be varying from 0.32 – 32.60 μSv/Year with the mean value of 10.69 μSv/Year |
