16-6 Assesment of isotonic thermal chlorosodic waters of the Middle Benue Trough, Nigeria for use in drinking cure / 日本温泉気候物理医学会雑誌

ABSTRACT

Introduction: Two springs namely Bitrus (flowing borehole) and Ruwan Zafi, both in Awe - North Central Nigeria were sampled and analysed for elements of pharmacodynamic significance. Methods: The electrometric method was used to determine electrical conductivity, pH value, iodide and fluoride content. The spectrophotometric method was used for the determination of ammonium, iron, magnesium, nitrate, nitrite, silicate, bromate, and sulphate content. Furthermore, the flame photometric method was used for the determination of sodium, and potassium content. Finally, the complexometric titration was used to determine calcium, and magnesium, the argentometric titration to determine chloride, while the acidimetric titration was used in the determination of hydrocarbonate. Result: Their rich mineral endowment is easily traced to their ancient marine source in the Cretaceous. These waters interact with host-beds of shale, silt, sandstone, which are sometimes calcareous on their way up under natural artesian conditions. With average temperature of 40 degree Centigrade, they make for invaluable balnear resources. Both springs have mineralization greater than 1000 mg/l and as such qualify as mineral/medicinal waters. Conclusion: Due to their Isotonic nature and moderate mineralization, they are suitable for use in drinking cure as their chemistry compares favourably with that of a well-known spring water in Poland used for the same purpose-Inowroclaw(mineralization 0.29%).
