Features of the content of drinking water in the city of Magadan and population health
By methods of atom-emission and mass spectrometry with inductively bonded argon plasma there was determined the content of 25 macro- and trace elements in tap cold drinking water used by the residents of the city of Magadan for food purposes and in hair samples of 30 young male Europeans aged of 17-23 years, who are the residents of the city of Magadan. According to our data the content of 25 elements in drinking water conforms to standards, but that content of such essential elements as Co, Cr, Cu, I, Mn, Na, Se, Zn is shown to be lower than referential indices. After boiling the water the concentration of trace elements is changed. The content of Cd, Cu, K, P, Pb, Zn, Ni becomes lower significantly. In healthy young men aged of 17-23 years, from the number of natives Europeoids, residents of the North there was detected deficit of Co and I (86% and 62%, respectively), lower concentrations of Ca, Mg, Se, Zn (76%, 69%, 24%, 24%, respectively). The constant use by residents of the city of Magadan of ultrafresh brackish drinking water in food aims may be the one of the main reasons of the imbalance of macro- and micronutrients in the body, characterized by features of the so-called "northern" type with a marked deficiency of basic essential elements.
