Resumo
Mineral water, according to the Brazilian Law N 7.841 of August 8, 1945, "are
those from natural springs or springs artificially captured that have chemical composition
or physical or physicochemical properties other than ordinary waters, with
characteristics that give them a drug action". In this same law, mineral waters can
be classified according to their chemical composition in: oligomineral, radiferous,
alkaline-bicarbonated, alkalineearthy, sulfated, sulphurous, nitrated, chlorinated, ferruginous,
radioactive, thorioactive and carbogasous. In several Brazilian hydromineral
resorts, springs of radioactive mineral water are commercially exploited and are consumed
by the population that believes this practice is beneficial. For example, in
thermal parks like Caxambu, Cambuquira, São Lourenço and Lambari (MG), the waters
of the various springs are used for human consumption and are often associated
with medicinal use, like diuretic and cathartic waters (with properties of cleaning,
purification, facilitating hepato-biliary functions and stimulating intestinal function
directly or indirectly), and waters with antiphlogistic properties (anti-inflammatory).
Therefore, due to the recommendation of these waters as a form of treatment spent in spas, the present work was developed in Centro de Radiometria Ambiental – IPEN,
with the aid of those responsible for the spas of Lambari and Águas de Contendas
and, with the objective to perform an inorganic chemical characterization of the
mineral waters of Parque das Águas of Lambari and Águas de Contendas. Samples
of mineral waters were analyzed in duplicates and concentrated from 500 mL. The
samples were irradiated at the IPEN Research Reactor IEA-R1, for a period of 6h
under a thermal neutron flux of 1012 n cm2s1. In the samples of mineral waters of
the Parque das Águas of Águas de Contendas the elements Ca, Co, Fe, Hf, K, Na,
Rb, Sb, Sc, Th, Zn, La and Sm were found. Similarly, in the Parque das Águas of
Lambari the elements Ca, Co, Fe, K, Na, Rb, Sb, Sc, Zn, La and Sm were found.
The analysis of the samples of these water parks evidenced that the elements of
greatest occurrence were La and Co.
