Procena zdravstvenog rizika upotrebe mineralnih voda na području Vrnjačke Banje – hemijski i mikrobiološki aspekt

Abstract

Cilj istraživanja je bio da se uradi procena rizika po zdravlje ljudi od upotrebe mineralnih voda iz Vrnjačke Banje. Procena je izvedena na osnovu rezultata ICP-OES analize hemijskog sastava voda i na osnovu bakterijske analize uzoraka. Ispitan je uticaj šest potencijalno toksičnih elemenata (As, Ba, B, Mn, Ni i Sr). Analizom akutnog i dugoročnog koeficijenta rizika po zdravlje ljudi utvrđeno je da ne postoji povišeni rizik osim dugoročnog rizika od pojave kancerogenih oboljenja usled prisustva barijuma. Vrednosti koeficijenta rizika, u tom slučaju, su bile oko 0,01 što je deset puta više od donje granične vrednosti. Rezultati bakterijske analize voda ukazali su na povišeno prisustvo aerobnih mezofilnih bakterija (25-90 jedinki/mL na 22°C tj. 6-28 jedinki/mL na 37°C) u uzorcima 03, 06 i 07 i sulforedukujućih klostridija u uzorku 05 (15 jedinki/50 mL).

The aim of this work was to make assessment of human health risk caused by consummation of mineral waters from Vrnjačka Banja. This evaluation was made based on results of chemical (ICP-OES) and bacteriological analysis of water samples from this spa. The influence of six potentially toxic elements (As, Ba, B, Mn, Ni i Sr) was examined. Acute and long-term hazard quotient (HQ) analysis has showed that there is no elevated health risk for human other than long-term risk of potentially carcinogenic diseases development due to the presence of barium in water. In that specific case, HQ values were about 0.01 which is ten times more than the lower limit value. According to bacteriological analysis of samples presence of aerobic mesophilic bacteria was determined (25-90 CFU/mL at 22°C ie. 6-28 CFU/mL at 37°C) in samples 03, 06 and 07, meanwhile, sulfite-reducing clostridia was detected only in sample 05 (15 CFU/50 mL).
