Düzce’de Satılan Şişe Suları İle Musluk Sularının Ağır Metal Düzeylerinin İncelenmesi

Türkçe

Objective: The aim of the study is to compare bottled spring water with Düzce tap water in terms of heavy metals content. Methods: To analyze the tap water samples were taken from 14 different determined locations at the same date. Commercial natural spring water samples were in 500 ml plastic bottles sold 10 examples from different brands. Heavy metal concentrations in water samples were measured by Inductively Coupled Plasma-Mass Spectrometer (ICP-MS). Results were evaluated based on the specified criteria of the US Environmental Protection Agency (EPA), the World Health Organization (WHO) and the Ministry of Health of Turkey. Results: Heavy metal levels in tap water and commercial water samples were lower than limits set by EPA, WHO and the Ministry of Health of Turkey. Average heavy metal content of the commercial water was found to be statistically significantly lower than average tap water heavy metal level, including boron (B), aluminum (Al), chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), arsenic (As) strontium (Sr), molybdenum (Mo), cadmium (Cd), mercury (Hg) and lead (Pb). Conclusion: In terms of heavy metal levels it that is safe to drink tap water and commercial bottled waters.
