Monitoring the levels of radon and toxic elements pollutants in bottled drinking water

Background: the existence of radioactive isotopes and toxic elements inwater poses a potential threat to public health. due to the high consumptionof bottled water, the focus of this study is on measuring the concentration ofradioactive isotopes (222rn and 226ra) and toxic elements (cr, mn, co, ni, cu,zn, cd, pb) in different brands of bottled drinking water. materials andmethods: therefore, twenty-four samples of bottled water have beencarefully selected from local markets in saudi arabia. nuclear track detectorof type cr-39 and inductive coupled plasma-mass spectrometer were used tomeasure radioactivity concentrations and toxic elements, respectively.results: it is observed that the activity concentration of 222rn and 226ra in allsamples was lower than the recommended values set by different agenciessuch as who, and epa. the annual effective dose for three age groups(infants, children, and adults) was calculated from the concentration of 222rn.these measurements provide basic information for consumers who could beat risk of exposure through bottled water consumption. conclusion: then alltypes of bottled drinking water are suitable and safe for daily populationingestion.
