Abstract
The aim of this study is to determine natural radioactive and heavy element concentrations in Mersin drinking waters before commissioning of Akkuyu nuclear power plant and to collect data that will be reference for possible environmental contaminations in the future. Therefore, this study comprise whole of the province. Drinking water samples were taken from provincial center, districts and populated villages. Water samples were analysed to determine radioactivity and heavy metals concentrations. The annual effective dose equivalent taken from natural radioactive substances and cancer risks were calculated for each people living in the city. In addition, Hazar Index (HI) and cancer risk were calculated, which were caused by heavy elements. The mean gross alpha and beta radioactivity concentrations in drinking water were measured 0.059±0.051 Bq/L and 0.120±0.095 Bq/L, respectively. The annual cumulative effective dose for people was found as 30.83 μSv and the average estimated excess cancer risk related this exposure was calculated as 16.9×10-5. Also, mean metal concentration of Cr, Ni, Zn, Cu, Ba and Cd in drinking water were determined as 1.33, 4.65, 54.8, 11.1, 26.3, 0.36 μg/L, respectively. Pb and As in all water samples were determined lower than detection limits (LDL). The hazard quotient (HQ) of heavy metals was decreased in the order of Cd > Cr > Cu > Ni > Zn > Ba in water. Mean calculated Hazard Index (HI) depending heavy metal concentration is found to be 6.8×10-1 for drinking water. Cancer risks of heavy metals are decreased in the order of Cd > Cr > Ni for the region.
