Abstract

Introduction: Cuba has a large reserve of natural peloids, specifically of coastal, saline and hydrothermal origin. Currently, peloid-based therapy is included in the national integral rehabilitation system, starting from the secondary level of health care. However, the current status of the chemical characterization of such peloids in Cuba is rather poor. Even though a Cuban Norm for Peloids exists, its scope is limited, because it does not regulate the permissible limits for organic compound and inorganic elements (including radionuclides) present in the peloids, as indicators of pollution and potential toxicity for humans. Objectives: To develop a procedure involving nuclear and nuclear-related techniques that enables the physicochemical characterization of the main natural peloids being used for therapeutic purposes in the country.
Methods: The combination of determining the physicochemical parameters, the inorganic/organic and radiological composition, as well as the morphological and structural characteristics in order to assess the quality of the main national peloids.
Results: For the first time, the organic, inorganic and radiological characterization of the main Cuban peloids has been studied, allowing the evaluation of the peloid's quality based on established radiological norms and values from international guidelines for sediments and cosmetic products guidelines. This study provides the scientific basis for the development of future regulations for the therapeutic use of peloids.
Conclusions: The physicochemical characterization performed on national peloids permitted their classification as non-contaminated in relation to the determined trace elements and to the identified organic compounds. On the other hand, the determined levels of equivalent radioactive dose do not exceed the levels for occupationally exposed persons or therapy users, established by the international regulatory organisms. A scientific basis for the preparation of future regulations for the therapeutic use of national peloids was provided.
