Survey of uranium concentrations in drinking water in Inner Mongolia autonomous region
Objective To investigate of the concentrations of uranium in drinking water in Inner Mongolia Autonomous Region for providing theoretical basis for the health protection of local residents and the assessment of nuclear emergency.Methods During the dry season and wet water season,tap water and well water samples were collected from 12 cities in Inner Mongolia,644 unfiltered water samples and 34 filtered water samples were collected,and the uranium concentrations in drinking water was measured using a trace uranium analyzer.Results During dry and wet seasons the uranium concentration were 0.85-23.61 μg/L and 0.98-23.65 μg/L in tap water,3.74-88.28 μg/L and 3.68-95.36 μg/L in well water,respectively.Conclusions The levels of uranium concentrations in drinking water in Inner Mongolia has been preliminarily ascertained,and the installation of filtration devices can significantly reduce the content of uranium in drinking water.
