The main objective of this study was to estimate the drinking water quality and public health assessment due to nitrate, nitrite and fluoride contaminations in Ahmadpur East, Punjab, Pakistan. Thirty-six drinking water samples were collected in the study area. Concentrations of geo-chemical parameters (pH, TDS and EC), nitrate, nitrite and fluoride were examined. The mean values of concentrations of nitrate, nitrite and fluoride were found 0.4197, 0.006 and 0.67mg/L, respectively. Mean values of potential of hydrogen (pH), total dissolved solid (TDS) and electrical conductivity (EC) were found 7.28, 630ppm and 1257 μS/cm, respectively. Health risk assessment was estimated by chronic daily intake (CDI), hazard quotient (HQ) and Total Health Index (THI) due to fluoride, nitrate and nitrite for infants, children, teenagers and adults. The CDI and HQ of fluoride estimated greater permissible limit in different age groups than nitrite and nitrate in urban region of the study area. THI in...
