Analysis, Assesment and Principal Component Analysis of Heavy Metals in Drinking Waters of Industrialized Region of Turkey

Since they may expose to inorganic pollutants, drinking waters should be investigated and monitored in industrialized regions. In this study, drinking water samples taken from eight different locations in heavily industrialized region of Turkey, namely Marmara region, were analyzed to determine heavy metal and harmful trace element (Fe, Co, Cd, Hg, Pb, Zn, Sb, Cu, Ba, Mo, Cr, Mn and V) concentrations. Besides analytical analysis, principal component analysis (PCA) technique, spatial relationships related to these metal elements were also examined. Inductively Coupled Plasma-Mass Spectrometer (ICP MS) was used to determine the metal concentrations. The average concentrations in ìgL-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 3. ; Sr 252. The obtained results indicated that the heavy metals concentrations in drinking water samples did not exceed the limits values declared in the guidelines of WHO (World Health Organization), EPA (Environment Protection Agency) and TSE-266 (Turkish National Standards). However, some V and Cu concentrations found to be very close to tolerable limits declared by EPA.
