The analysis of some physicochemical parameters and the heavy metals of Cr, Co, Ni and Cu were
carried out in samples of plastic bottled drinking water of Seven brands in Iraqi Kurdistan Region for a three
sampling collection during November 2013 to May 2014. The analysis of different parameters namely; pH, turbidity,
total hardness, dissolved oxygen (DO), chloride (Cl-), calcium (Ca+2) were carried out as per standard methods. The
present study aimed to compare the measured results of the physicochemical properties of the bottled water with the
reported results on the plastic bottles of the manufacturer’s labeling brands and also to compare with the guideline
value of World Health Organization (WHO). Furthermore, this study also objected to indicate the levels of these
heavy metals (Cr, Co, Ni and Cu) content in the samples of the studied brands. The results obtained were found
exceedence of WHO drinking water standard for Chromium & Nickel in Life, Alla, and Kani; exceedence for Nickel
in OXAB and Hayat; even so they have not been reported on the label. Therefore, further studies are recommended;
especially, analyses of microbiological tests, and also analysing more heavy metals.
