title: [Calcium, magnesium, iron and zinc in drinking water and status biomarkers of these minerals among elder people from Warsaw region].
abstract: The aim of this study was to estimate the influence of calcium, magnesium, iron and zinc contents in drinking water on chosen parameters of nutritional status of these minerals in 164 elder people, 75-80 age, living in Warsaw region. Blood, hair and saliva were collected to assess the calcium, magnesium, iron and zinc nutritional status, while the samples of drinking water were collected to determine these minerals in water Mineral concentrations in blood, hair saliva and water were assessment using the atomic spectrophotometer absorption method It was showed that contribution of drinking water to calcium, magnesium, iron and zinc intake was: 15%, 4%, 5%, 9%, respectively. The relationship between the contents of these minerals in drinking water and their levels in the blood, hair and saliva had low correlation coefficients. It probably showed that homeostasis was maintained in the human body and other factors such as demographic or lifestyle factors were important.
