RESUMEN
This study aims to estimate geothermal potential, radioactivity levels, and environmental pollution of six most popular spas in Central Serbia (Ovcar, Gornja Trepca, Vrnjacka, Mataruska, Bogutovacka and Sokobanja), as well as to evaluate potential exposure and health risks for living and visiting population. Thermal possibilities of the studied spas showed medium and low geothermal potential with total thermal power of 0.025â¯MW. Gamma dose rates in air varied from 63 to 178â¯nSv h-1. Specific activities of natural radionuclides (226Ra, 232Th and 40K) and 137Cs in soil were measured; annual effective doses and excess lifetime cancer risk from radionuclides were calculated. Radon concentration in thermal-mineral waters from the spas ranged between 1.5 and 60.7 Bq L-1 (the highest values were measured in Sokobanja). The annual effective dose from radon due to water ingestion was calculated. The analyzed soils had a clay loam texture. The presence of As, Cr, Cu, Fe, Mn, Ni, Pb, Cd, Zn, and Hg in soil was investigated. The concentrations of As, Cr, Ni, and Hg exceeded the regulatory limits in many samples. Soil samples from Mataruska spa were generally the most contaminated with heavy metals, while the lowest heavy metal concentrations were observed in Sokobanja. Health effects of exposure to heavy metals in soil were estimated by non-carcinogenic risk and carcinogenic risk assessment. Total carcinogenic risk ranged between 6â¯×â¯10-4 and 137â¯×â¯10-4 for children and between 0.1â¯×â¯10-4 and 2.2â¯×â¯10-4 for adults. The sum of 16 PAHs analyzed in soil samples varied from 92 to 854⯵g kg-1.

A number of factors, for example water temperature, can encourage the growth of microorganisms such as Legionella spp in spa facilities. Individuals who attend this type of facility are often subjects at risk for infection who are undergoing inhalation therapy and hot tub treatments. A very accurate management of these facilities is therefore required to avoid infection by Legionella spp. The purpose of this study was to verify the current Italian national and Apulia regional legislation regarding the control of contamination by Legionella spp. in spa facilities.

Japan is situated on the Pacific fire rim and has a large number of hot springs (onsens). There are over 27,000 sources of such springs and the country has a well regulated system of onsens. Within this geographical and cultural peculiarities certain unique traditional health practices have evolved, prominent among which is Touji or onsen therapy. The article highlights various healing practices surrounding onsens, institutionalization of these practices, current policy regulations, standards and their contemporary challenges. This research used publicly available information from literature sources and data through expert interviews. It draws attention to the fact that touji has been marginalized in the recent health policies. The study highlights that onsen as a therapeutic landscape has an important role in maintaining health and wellbeing in the country and holds immense value in building social cohesion in local communities. The study points to the need for appropriate studies on the social and symbolic healing elements related to onsen landscapes, as well as the need for developing a comprehensive strategy for strengthening their culturally specific health management roles.
