Salt waters of the Tuzla Region are saturated salty solutions with sodium chloride as a dominant component. According to the results of the previous analyses these waters are classified as the sodium-calcium-magnesium-potassium-chloride-sulphurous boron mineral water. The content of biological active oligoelements (zinc, copper, chromium, sulfur, selenium) was determined. This research involved a chemical analysis of the salt water and the salty solutions that are being used in balneotherapy in the Tuzla Sanatorium "Slana banja". The analysis showed a significant content of sulfide-sulfur either in natural or in diluted salt water and we monitored its concentration in the course of balneotreatment of the patients.
The salt water chemical analyses revealed a high concentration of chloride (175000 mg/L), sulfate (6300 mg/L), boron (170 mg/L), magnesium (110.11 mg/L) and sulfide-sulfur (41.34 mg/L). The content of the same components decreased to one third in the diluted salt water.
The concentration of fluoride (>0.1 mg/L), copper (1.25 mg/L), zinc (0.45 mg/L) and selenium (>0.01mg/L) are not significant from the aspect of balneology. Sulfide-sulfur losses due to evaporation and possible oxidation in the course of balneotreatment (11.70%) were evidenced. In spite of this, sulfide-sulfur concentration in the salt water being used in balneotherapy, is higher than the minimal highest concentrations required for its penetration (9.43 mg/L).
The results obtained give new information on the Tuzla salt waters quality and they can also be characterized as sulfide-mineral water (sulfur-bath) according to the classification of mineral-curing waters. This research is a contribution to the researches on the Tuzla salt waters in the light of balneotherapy, and gives a new significance to these waters as a natural factor of medical rehabilitation.
