Comparative Distribution of Selected Essential Metals in Drinking Water by Atomic Absorption Spectrophotometric Method

This study reports the concentration levels of selected essential metals; Ca, Mg, Na, K, Fe and Zn in the drinking water collected from different areas of Islamabad. The levels of these metals present in the drinking ground water were compared with standards reported worldwide. The analysis was carried out using atomic absorption spectrophotometry. The mean metal concentration for Na was far less than those reported worldwide, while the average concentrations of K and Zn were also less than those reported worldwide. The mean concentration of Fe was equal to those reported worldwide standards. Sodium showed maximum concentration while Fe was estimated to be the lowest among the selected metals.
