Sažetak
Water is an essential substance for all living organism and it is a source of various nutritive substances. Natural water, i.e. water that is free of the products of human activities, generally reflects the geochemistry of the environment through which it flows. At the same time, water is at risk of pollution due to various human activities, such as industry or traffic. Awareness of the endangering of natural water resources as well as knowledge about leaching of some heavy metals from plumbing system (e.g. Cu, Ni, Pb), resulted, among others, in the interest of people all around the world in everyday use of bottled, commercially distributed, water. Along with the production and consumption of bottled water, that are permanently increasing, an interest of the researchers in testing of the commercially distributed bottled waters has been occurring worldwide during the past several years and a survey of scientific database Web of Science reveals that scientific papers dealing with the results of various testings of bottled waters are regularly published. Bottled water can be of natural origin, or its qualitative and quantitative composition can be regulated by processing in a production plant. Therefore, metals and metalloids content of a bottled drinking water can reflect geochemistry of its origin, but can also, intentionally or unintentionally, introduced during the production process, filling of bottles, etc. Also, some elements can be leached from the material of a bottle. Thus it is well known that aluminium (Al) or lead (Pb) can be leached from glass bottle into water, while from PET bottles the leaching of antimony (Sb) occurs. In this work, determination of ca. 20 selected chemical elements (Al, As, B, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Sr, Ti, Tl, V, Zn) in the bottled waters of different brands was performed. For this communication, only those bottled waters which are labeled as “product of Croatia” were analyzed: 19 brands of still and sparkling water were included in the study. The samples were randomly taken from various supermarkets in the town of Zagreb, with the intention to find as much as possible various Croatian brands of bottled drinking water. Determination of almost all elements was done by direct measurement of the previously acidified (HNO3, supra pur, ψ = 1 %) samples of the waters by mean of atomic emission spectrometry with inductively coupled plasma (ICP-AES), while calcium was measured in 100- fold diluted sample solutions.
