Abstract

The article discusses the impact of the hardness of drinking water on human health and some results of our research in this area are given. The main aim of the study is to determine the content of calcium and magnesium cations in drinking water of filling points and assessing possible effect of such water on the health of Lviv residents. In 10 samples of drinking water taken at different filling points it is determined: total hardness and calcium by complexometric method; magnesium hardness as the difference between total hardness and calcium hardness; total alkalinity in the water samples during titration of HCl solution. It is calculated concentration of calcium and magnesium cations for values of calcium and magnesium hardness. The results show that no sample does not meet the physiological usefulness of drinking water by concentrations of calcium and magnesium cations. The content of these elements in water is lower than the normative value. Comparison of the total hardness and total alkalinity enables suggests that water previously processed on filters with cation exchange loading. Water of all investigated samples is very soft with a total hardness 0-1,4 mM/dm3. Over consumption of such water there is a danger of population infestation by cardiovascular diseases.
