Resumo
Chemical composition of mineral water is the result of soil and water interaction
and depends on the soil geology, because the chemical elements become part of
these waters through the leaching and dissolution processes of soil. Mineral waters
are defined as those that come from natural springs or that are artificially collected
with chemical composition or physical chemical properties which imbues them with
medicinal action that distinguishes them from ordinary water.
According to the mineral summary of Departamento Nacional de Produção Mineral
- DNPM, the consumption of mineral water has been increasing year by year,
being in 2014 the global consumption 6.2% greater than in 2013 (which already
had consumption 7.0% greater than in 2012), a fact that reinforces the importance
of the characterization and regulation of the mineral waters. In thermal parks as
Caxambu’s park, the waters are used as health therapy, diuretic waters, cathartic
waters and anti-inflammatory waters. Parque das Águas of Caxambu, the largest
mineral water park in the world, has 12 springs: Leopoldina, Beleza, Duque de Saxe,
Princesa Isabel and Conde D’Eu, Dom Pedro, Viotti 1 and 2, Venâncio, Mayrink I,
II and III and Ernestina Guedes and also a 60 m deep geyser. Thus, the main goal
of this study was to perform a chemical characterization of these waters in which
the elements Ba, Ca, Co, Cr, Cs, Eu, Fe, K, La, Na, Rb and Sb were found using
Instrumental Neutron Activation Analysis – INAA technique. Mineral water samples
were dried in a cellulose substrate and irradiated at the IEA-R1 reactor in which they
were exposed for 6h to a thermal neutron flux of 1012 neutrons per cm2 per second.
The results showed a similar behavior among the samples and it was possible to
identify a higher concentration of Na, K and Fe and predominance of alkaline and
alkaine earth metals in all samples. Further, Venâncio, Beleza, Ernestina springs and
geyser showed the highest concentrations of these elements.
