Title

Determination of radon concentration and heavy metals (Ni, Pb, Cd, As, Cr) in drinking and irrigated water sampled from Kulim, Malaysia

Pages

  341-349

Abstract

 Background: The presence of heavy metals and radon in Water are considered as a poten al threat to public health. Modern day industrializa on has led to increase pollutants in ecosystem whilst the main source of public radia on exposure, especially exposure from radon, is caused by portable Water. This study aimed to es mate the health risk related to radon concentra on and heavy metals in drinking and irrigated Water. Materials and Methods: Water samples, from different sources, were collected from Kulim, Malaysia and analyzed for radon and heavy metals using RAD7 and Atomic Absorp on Spectrometry. Results: Results showed that the maximum average value of radon concentra on (16. 06± 1. 7) Bq/l was found in well Water used for drinking and irriga on. Minimum average value of radon concentra on (2. 65± 0. 33) Bq/l was found in tap Water used for drinking purpose. From the measured radon concentra ons, age dependent associated annual effec ve doses and contribu on of radon in drinking Water to indoor air was calculated which were found below the lower limit of recommended ac on level. Metal concentra ons were found higher in stream and lake Waters used for irriga on, compared to well and tap Waters. The average daily intake of drinking Water and health risk indices were found higher for infants and lower for children and adults. Conclusion: radon concentra ons in well, stream and lake Waters were found higher than EPA recommended level and lower than WHO ac on level while the annual effec ve doses and level of heavy metals in Water reported in this study were found lower than recommended levels.
