Resumo
Introduction: Since the early days of humankind, peloids have been used for therapeutic purposes. However, the
safety and efficacy of these materials for therapeutic treatments has never been regulated in most of the countries
where it is commonly used.
Materials and methods: In this study, samples os peloids from different regions of Brazil (´Aguas de S˜ao Pedro,
Paraty and Arax´a) were characterized: mineral composition (X-ray diffractometry), physicochemical characteristics
(pH, redox potential, moisture, % loss on ignition at 550 ◦C and 1000 ◦C, cooling kinetics, swelling
power, specific surface area), concentration of trace elements (X-ray fluorescence, Neutron activation analysis,
Graphite furnace atomic absorption spectrometry) and radiological activity (Gamma spectrometry).
Results: The results showed great variability in mineral composition, physicochemical characteristics, elemental
concentration, concentration of activity and little variation in cooling kinetics. However, this variation is also
found when comparing the results with some those presented by other authors.
Conclusion: This study concludes that the three peloids studied are good candidates to be used for topical
application. Metals and potentially toxic elements present are in concentrations levels that are unlikely to cause
risk to health.
