Absztrakt (kivonat)
In this paper there are presented the results of studies performed on characteristics of some existent mineral waters, in three different regions of Romania (West Region, Centre Region and North Region). Regarding this aim, the quantitative chemical analysis of macro elements: sodium (Na), potassium (K), calcium (Ca) and magnesium (Mg) was performed, using a flame atomic absorption spectrometer VARIAN Spectr AA 110 type. In this case, the flame emission and absorption method was used. As a conclusion, for sodium the maximum value recorded in mineral waters from the three regions taken into discussion, was obtained in sample A1 (294 mg/L) in the west region, for potassium the maximum reached was 47.4 mg/L in sample B3 in the north region, for calcium the maximum value was recorded as 330 mg/L in sample A3 from north region, and magnesium recorded the maximum value of 76 mg/L in sample B3 for north region. All samples studied, are within normal limits established by law.
