RESEARCH ON NaCl SALINE AEROSOLS I. NATURAL AND ARTIFICIAL SOURCES AND THEIR IMPLICATIONS.

This paper is the first of a series of new researches on the NaCl aerosols, which includes the bibliographical analysis and synthesis regarding the structure, the form and the sizes of the particles of the NaCl aeroions in correlation with the production procedures. There are also analyzed some practical applications pointed out both by some ancient Greek and Roman texts and by the presentday literature; at the same time there is underlined the existence, even from Antiquity, of an ethnoscience which led to the current knowledge in the halotherapy field. Concerning the artificial sources of the aerosols employed in the multiple-usage halochambers, there have been taken into consideration the most well-known procedures which are based on the mechanical separation or erosion, followed by the physical dispersion in the atmosphere; on the breaking of the gas bubbles in the sparging with air or other inert gases by means of the supersaturated saline solutions; on the atomization of the saturated saline solutions in the vacuum centrifugal air separators and the carrying-away of the superficial particles resulted from solvolyses and the consecutive anhydrizations of the structures from the surface of the halite blocks. These procedures will be included in the subsequent research. [ABSTRACT FROM AUTHOR]
