 Abstract:

   The main objective of the research was to make a comprehensive assessment of bottled water produced in the Republic of Crimea, as well as of several popular brands of water from the sources of Russia (“Holy spring”) and Italy (“ASQUA PANNA”), in terms of their physiological usefulness, with the identification of possible risks to the health of consumers. To achieve this goal, 10 brands of bottled water were purchased in the trading networks of the Peninsula. Also, for comparison, a sample of tap water supplied to the population of Simferopol was selected. All samples were transferred to the accredited laboratory of the Institute (experimental part), which determined the following indicators: dry residue, pH, Ca2+, Mg2+, Na+, K+, HCO3–, SO42-, Cl–, PO4-, NO32-.

   As a result of the comparative analysis of the obtained salt composition of the studied water samples with the current standards in the Russian Federation (SanPiN 2.1.4.1116–02 “physiological usefulness”, SanPiN 2.1.4.1074-01, GN 2.1.5.1315-03 “quality of drinking water”), deviations of the chemical composition of some water samples from the requirements of the standards for bottled water, as well as inconsistency of the composition presented on the label were revealed. Of the 10 samples studied, none met the standards of “physiologically complete” water. All samples had low content of chlorides, sulphates, potassium, magnesium, sodium, calcium, mineralization, and pH. Also on the label there was no information about the pH value, which is one of the main indicators characterizing the quality of the water used.

Keywords: bottled water, physiological usefulness, chemical composition, public health, drinking water.
