Analysis of Uranium Concentration in Drinking Water Samples Using ICPMS

Abstract

Uranium concentration in drinking water samples collected from some areas of Northern Rajasthan has been measured using inductively coupled plasma mass spectrometry. The water samples were taken from hand pumps. The uranium concentration in water samples varies from 2.54-133.0 μg L with a mean value of 38.48 μg L. The uranium concentration in most of the drinking water samples exceeds the safe limit (30 μg L) recommended by the World Health Organization. The annual effective dose associated with drinking water due to uranium concentration is estimated from its annual intake using dosimetric information based on ICRP 72. The resulting value of the annual effective dose from drinking water sources is in the range of 2.11-110.45 μSv. The annual effective dose in one of the samples was found to be greater than WHO-recommended level of 100 μSv y.

Measurement of soil-gas radon in some areas of northern Rajasthan, India

“…High radium content in soil samples and uranium content in water samples were reported in Sri Ganganagar district of Rajasthan State by our group (Duggal et al 2013;Rani et al 2013). The aim of the present investigation is to examine the concentration of radon in the soil-gas of Sri Ganganagar district, Rajasthan at different depths and to find a relationship between the soil-gas radon concentration and depth.…”

Ingestion doses and hazard quotients due to intake of Uranium in drinking water from Udhampur District of Jammu and Kashmir State, India

“…Figure 3 shows the graphical representation of pH, TDS and Conductivity with different locations of Udhampur district. TDS concentrations of water samples are vary from 0.063-0.728 ppt, only 2-3% (Rani et al, 2013), Roper (Singh et al, 2008), and Malwa (Mehra et al, 2007) of Punjab; Kangra of Himachal Pradesh; Fatehbaad , Hisar (Kansal et al, 2011) and Sirsa (Kansal et al, 2011) of Haryana; and Kathua and Jammu (Kumar et al, 2016) districts of Jammu & Kashmir are comparable to present work and Lower than Amritsar (Rani et al, 2013), Bathinda (Bajwa et al, 2015), Andrah Pradesh (Brindha and Elango, 2013), and Western Haryana (Singh et al, 2014) as shown in Table 4. The reported values were also compared with worldwide as shown in Table 5.…”

“…10 (Kumar et al, 2016) to remove suspended particle and is transferred to 50 mL polyethylene plastic bottles previously cleaned with distilled water. The fluorimetric method for Uranium is among the most sensitive and efficient, of detection limit 0.5 mg L À1 to 1000 mg L À1 with an accuracy of ±10% or 0.05 mg L À1 whichever is greater and repeatability is better than ±5% (Kumar et al, 2016) and in ICP-MS, the precisions achieved were ±5% relative standard deviation (RSD) with comparable levels of accuracy (Rani et al, 2013). Uranium concentration of collected samples was calculated by LED-Flourimeter (Quantalase Enterprise Pvt.…”

“…Uranium is the naturally occurring heaviest radioactive toxic element and occurs naturally in low concentrations of a few parts per million in all type of soils, rocks, plants, sands, bedrocks and water. Due to its presence in the certain types of rocks and soils, the water passing through and over the rock and soil formations dissolves many compounds and minerals; therefore, varying amounts of Uranium are present in some water sources (Rani et al, 2013). Natural water such as seawater contains a few traces of Uranium of range 0-4 ppb and up to 1000 ppb in surface (Singh et al, 1999).…”

Uranium Levels in Groundwater of North India

“…The uranium concentration in Hanuman Garh district varies from 4.74 to 98.7 µg/L and Shri Ganga Nagar District from 4.42 to 133.0 µg/L, Churu district from 10.75 to 81.3 µg/L and Sikar district varied from 2.54 to 28.38 µg/L used inductively coupled plasma mass spectrometry (ICPMS) for the measurement of uranium in water [20]. Parameters for radiological effect of uranium such as annual effective dose, commutative dose and life time stochastic health effect in Rajasthan was within safe limit [20].…”
