Abstract |
|
|
| Natural uranium is found in various sources of water and its assessment in drinking water is important from viewpoint of public health. Intake of uranium through air and water is normally low, but in circumstances in which uranium is present in a drinking water source, the majority of intake can be through drinking water route. Present report is a preliminary study on evaluation of uranium in ground water of Tiruvannamalai district, Tamilnadu, India. Water samples were randomly collected from hand pumps around Tiruvannamalaidist, Tamilnadu. Concentrations of uranium in the samples were measured using the LED fluorimetric technique. Results showed variations in concentrations obtained from place to place and values ranged from1.9 to 23.4 ppm with the mean value of 6.94ppm.The measured values were found lower to permissible limits of AERB, USEPA, WHO, UNSCEAR and ICRP. Risk assessment of uranium in water is also calculated using life time cancer risk, life time average daily dose and hazard quotient. Finally it was concluded that there was no excess lifetime cancer risk and chemical risk to humans due to uranium concentration in water of the study area. |
