Short report 22.09.2015, Action A5 “Environmental analysis”
Abstract
Based on linking of wide range of chemical elements in soil and groundwater through neural network analysis (ANN), following chemicals having the most significant influence on human health of Slovak population were identified: groundwater contents of Ca, Mg and water hardness (Ca+Mg). Low, deficit contents of these three parameters of chemical composition of groundwater/drinking water have significant influence on increased mortality for cardiovascular and oncological diseases. Both diseases represent decisive cause of deaths in the Slovak Republic (about 75% together).
The elaborated limit values for these environmental indicators for drinking water used for public water supply were defined at following levels: Ca+Mg = 2 – 6 mmol.l-1, Ca > 40 mg.l-1, Mg = 20 – 60 mg.l-1. For bottled water we propose limit values for Ca >50 mg.l-1 a Mg > 25 mg.l-1.
