Abstract
Heavy metals are natural ingredients of the Earth’s crust. Due to their persistence, high toxicity and the tendency to accumulate in the ecosystem, heavy metals pose a threat to human health. The aim of the paper is to examine the content of heavy metals in the PET packaging of water, the pH value as well as the electrical conductivity of commercially produced bottled water. The analysis used bottled water purchased in Una-Sana Canton markets from twelve different manufacturers. PET packaging samples were digested in the microwave oven Anton Paar Multiwave PRO, and analysed on the PerkinElmer Atomic Absorption Spectrum AnalyserAAnalyst 800 with Zeeman correction. Cadmium (Cd), lead (Pb), cobalt (Co), zinc (Zn), and iron (Fe) were analysed by flame technique. The measured concentrations of heavy metals in PET packaging were low, and these values do not deviate from the European Parliament and Council Directive 94/62/EC on packaging and packaging waste. The electrical conductivity for all samples was in accordance with the Ordinance on table water in B&H. The analysed PET packaging does not present a danger to human health because the measured concentrations of heavy metals comply with Directive 94/62/EC.
