[Impact of the mineral composition of drinking water on children's health].
The purpose of this investigation was to evaluate the effect of highly mineralized drinking water on children's health. To reveal a relationship of children's health to the chemical composition of portable water, two Kazan districts differing in the conditions of water supply and the mineral composition of the water were selected. A total of 833 schoolchildren aged 7-9 years underwent a questionnaire survey and their objective status was examined. Special methods were used to determine the urinary content of trace elements, such as copper, zinc, cadmium, and gross elements, such as calcium and magnesium, by performing atomic absorption spectrophotometry on an AAS-SA 10 MP apparatus.
