摘要：Ninety drinking water samples of fifteen each from three urban and three rural areas of Peshawar were collected and analyzed for their heavy metals, minerals, SO4, NO3 and Cl. In the urban area were Hayatabad, City and Sadder while from rural area Shikhmohamadi, Palosi and Jagra. Among the heavy metals and minerals Pb, Cr, Fe, Zn, Mn, Ca, Cu and Mg were determined by atomic absorption spectrophotometer, Na and K by flame photometer, Cl by titration method, SO4 by spectrophotometer and NO3 by nitrogen analyzer. The mean value of Pb, Cr, Fe, Zn, Cu and Mn among different locations were, 0.15±0.11, 0.21±0.05, 0.68±0.15, 0.09±0.14, 0.11±0.03 and 0.01±0.01 mg/L respectively. The mean value of Na, Mg, K and Ca were 26.61±3.70, 23.47±4.24, 3.11±1.77 and 40.96±16.94 mg/L respectively. For SO4, NO3 and Cl mean value 12±6.54, 5±1.26 mg/L and 14±4.90 mg/L respectively. Minerals content result obtained indicated that their level in different locations were in safe level as recommended by WHO and for heavy metals they are above the safe limit as recommended by WHO. Hence considered unfit for drinking purpose and it was concluded that the water from Peshawar region should be checked and monitored regularly in order to omit all possible sources of contamination or to reduce it.
