Hydrogeochemistry characteristics of groundwater and health risk assessment in Yalvaç–Gelendost basin (Turkey)

Abstract In this study, hydrogeochemical processes controlling groundwater chemistry and quality were investigated. Drinking water is supplied from (mostly spring well water) in the study area. The various parameters such as physicochemical parameters, major ions, trace elements nitrogen derivatives of samples analyzed. These analysis results are compared with drinking standards for suitability it does not exceed permissible limit values, except As F contents some samples. ion Yalvaç–Gelendost basin suggest that silicate weathering exchange main variation quality. types Ca–Mg–HCO 3 , Mg–Ca–HCO Ca–HCO basin. Non-carcinogenic health risk assessment associated arsenic, nitrate fluoride was assessed by oral (ingestion) dermal pathways adult child. For child, hazard coefficient index values less than 1, a negative effect on usage (skin contact) absorption expected. But, potential non-carcinogenic intake likely to occur adults. addition, carcinogenic element evaluated adults child related effect. through may pose risks children. adults, has been determined ingestion exposure cause cancer. Arsenic toxic human content decreases seasonal case, arsenic decreases.
