The Analysis and Evaluations of Heavy Metal Concentrations in Tap Water Samples Taken from Different Locations in Marmara Region

Abstract

Chemical qualification of water we consumed is so important in that sustainable healthy life. The water should not include hazardous material such as heavy metals and metalloid and their concentrations should not exceed tolerable limits declared in the guidelines of WHO (World Health Organization), EPA (Environment Protection Agency), Turkish Water Pollution Control Regulation. As part of study, drinking water samples were taken from eight different locations that has intensive industrial characteristic and their heavy metal concentrations were determined with Inductive Coupled Plasma Mass Spectrometry (ICP-MS). The mean concentrations in μgL^-1 were as follows: Hg, Cd and Co BDL ; Pb 0.18 ; Zn 27.32 ; Sb 0.04 ; Cu 6.35 ; Mn 2.15 ; Cr 1.07 ; V 1.86 ; Mo 0.52 ; Ba 35.22 ; Sr 252. As a result of present survey, it was seen that some elements concentration (V and Cu) found to be very close to their threshold limits.
