Summary
Uranium levels in Northern Rajasthan
Area of Science:
- Environmental Science
- Public Health
- Analytical Chemistry
Background:
- Drinking water quality is crucial for public health.
- Elevated uranium levels in water pose health risks.
- Contamination of groundwater sources is a growing concern.
Purpose of the Study:
- To measure uranium concentration in drinking water from Northern Rajasthan.
- To assess health risks associated with uranium exposure.
- To compare findings with World Health Organization (WHO) guidelines.
Main Methods:
- Inductively coupled plasma mass spectrometry (ICP-MS) was used for uranium analysis.
- Water samples were collected from hand pumps in Northern Rajasthan.
- Annual effective dose was calculated using ICRP 72 dosimetric information.
Main Results:
- Uranium concentration ranged from 2.54-133.0 μg/L, with a mean of 38.48 μg/L.
- Most samples exceeded the WHO safe limit of 30 μg/L.
- Annual effective dose ranged from 2.11-110.45 μSv, with one sample exceeding 100 μSv/y.
Conclusions:
- Drinking water in Northern Rajasthan shows significant uranium contamination.
- Public health is at risk due to exceeding safe uranium limits.
- Further investigation and mitigation strategies are recommended.

01:19Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview
In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then passed on to...
01:20Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Interferences
Inductively coupled plasma–mass spectrometry (ICP–MS) is a highly selective and sensitive technique for accurate elemental analysis. Though the analysis of ICP–MS mass spectra is comparatively straightforward, it is affected by spectroscopic and non-spectroscopic interferences. Spectroscopic interferences arise when the plasma contains ionic species with an m/z value the same as the analyte ion. Spectroscopic interference can be categorized as isobaric, polyatomic ions, and refractory oxide ion...
01:19Inductively Coupled Plasma Atomic Emission Spectroscopy: Principle
Inductively coupled plasma (ICP) is the most widely used plasma source in atomic emission spectroscopy (AES), also known as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The ICP source, or torch, consists of three concentric quartz tubes with argon gas flowing through them. A spark from a Tesla coil initiates the ionization of argon, generating a high-temperature plasma.

01:17Precipitation and Co-precipitation
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
01:29Atomic Emission Spectroscopy: Lab
AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...
