Abstract
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 (Águas de São Pedro, Paraty and Araxá) 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.
引言自人类早期以来,类骨盆就被用于治疗目的。然而,在大多数常用这些材料的国家,这些材料用于治疗的安全性和有效性从未受到监管。材料和方法在本研究中,对来自巴西不同地区(Águas de São Pedro、Paraty和Araxá)的类骨盆样品进行了表征:矿物成分(X射线衍射法)、物理化学特性(pH、氧化还原电位、水分、550°C和1000°C下的灼烧失重%、冷却动力学、溶胀力、比表面积),微量元素浓度(X射线荧光、中子活化分析、石墨炉原子吸收光谱法)和放射性(伽马光谱法)。然而,当将结果与其他作者提出的一些结果进行比较时,也发现了这种变化。结论本研究的结论是,所研究的三种骨盆是用于局部应用的良好候选者。存在的金属和潜在有毒元素的浓度水平不太可能对健康造成风险。
