Abstract
In the present study, analysis of heavy metal and radon concentrations in ten water samples collected from the Khasa River in Kirkuk City, NE Iraq, was investigated. The measurement of the concentrations was carried out by the ICP-MS technique for heavy metal and RAD7 technique for radon. The average concentration values of the heavy metals in the unit parts per billion in the samples are in the following order: Cu (17.72) < Cr (9.42) < Ni (9.08) < Pb (6.78) < As (2.02) < Co (0.83) > Cd (0.1). Hazard quotient and hazard index were used to assess the non-carcinogenic health risk for exposure to heavy metals through ingestion and dermal. The results showed that there is no potential for non-carcinogenic health risk of exposure to heavy metals by ingestion and dermal. Radon concentrations varied from the lowest of 0.035 Bq/L to the highest of 0.359 Bq/L. The annual effected dose of radon was measured for both children and adults, where the annual effected dose average was 0.002893 mSv/year for children and 0.002048 mSv/year for adults, and these values are below the prescribed dose limit of 0.1 mSv/year by the World Health Organization.
