Should Children Drink Water with Very Low Mineral Content? Implications of the Global Expansion of Water Filtration Systems and Relevance of Consumption of Water with Higher Mineralization Levels
The consumption of water with very low mineral content (W-VLMC; water with total dissolved solids below 50 mg/L), despite limited and inconsistent evidence and the resulting knowledge gaps, has not been associated with health risks for the general population. However, certain population subgroups (those eating very unbalanced diets or avoiding certain foods, engaged in prolonged periods of fasting, and/or doing prolonged or strenuous exercise as well as pregnant or breastfeeding women) should be mindful of maintaining sufficient intake of all essential minerals through their food if regularly using this type of water as their main beverage. The rapid expansion of water filtration systems—often producing W-VLMC—creates a timely and valuable opportunity to advance research on the health implications of W-VLMC intake. As these systems become increasingly common in educational settings and homes, children represent a subgroup experiencing rising exposure to W-VLMC. Additional studies are needed to assess the health effects of such exposure from early childhood. A complementary yet contrasting perspective is that the use of water intended for human consumption—with stringent quality control standards—and natural mineral waters—inherently pure, thus eliminating the need for filtration—with higher mineralization in both types of water, may provide an additional dietary source of essential minerals, especially for all the population subgroups mentioned above.

Microplastic pollution and human risk assessment in Turkish bottled natural and mineral waters
Microplastics (MPs), which arise from the deterioration of larger plastics that are frequently used in daily life and are smaller than 5 mm in size, are found in many environments and can pose a serious threat to human health. Humans ingest these microplastics unintendedly through drinking water. Although plastic pollution has been extensively investigated in a variety of water sources, research on MP contamination in bottled waters is scarce. Hence, in this study, the presence and distribution of MPs were investigated in 150 samples of bottled natural and mineral water brands in Türkiye. Using FTIR stereoscopy and stereomicroscope analysis, MPs were detected in 43 out of the 50 (86%) of these brands. Among the four types of polymers detected, the most abundant type was polyethylene (33%), polypropylene (31%), polyethylene terephthalate (25%), and polyamid (11%). In comparison to natural waters, mineral waters had larger average-sized particles (63.98 ± 4.06 vs. 104.83 ± 14.28 µm) and higher MP concentrations (4.6 ± 0.5 vs. 12.6 ± 1.6 particles/L). Although the most dominant shape was found as fiber in natural waters, fragments were more prevalent in mineral waters. The estimated daily intakes (EDI) for adults and children were expected to be 0.019 and 0.42 MP/kg/bw/day, respectively, in natural waters while EDI were 0.009 and 0.04 MP/kg/bw/day, respectively, in mineral waters. The results of the study suggest that the EDI and annual intake (EAI) are negligible when compared to other studies. The baseline data on MP contamination of bottled water provided in the present study may be significant and useful for researchers to have a better understanding of microplastic contamination exposure.

Rethinking the concept of 'healing settlements' : water, cults, constructions and contexts in the ancient world : Roman Archaeology Conference 2016 : proceedings of the session of study (nr. 27), Sapienza University, Aula 'Partenone,' 17th March 2016
This volume brings together papers dealing with therapeutic aspects connected to thermo-mineral sites both in Italy and in the Roman Provinces, as well as cultic issues surrounding health and healing. The first part of the book consists of contributions that are focused on the numerous problems concerning the exploitation of curative springs and the settlement patterns at spa sites in terms of topography, infrastructure, architecture, cult, society and economy, emphasizing the particularities accompanying the use of beneficial sources and comparing them to that of common sweet waters. The papers in the second part of the volume are concentrated on religious aspects connected to health, fertility and healing, focusing especially on sites located at particular natural surroundings such as caves and water sources. Together, the contributions in this book give us an idea of the amount and quality of research currently being undertaken in different parts of the Roman world (and complemented by one paper on the Greek world) on the topic of health and healing associated with cults and salutiferous waters.

Radiological characterization related to lithology and risk assessment of bottled natural mineral water
The enhancement of natural radioactivity in groundwater, specifically in natural mineral water, is related to the lithological formations through which water bodies or courses pass. Although natural mineral waters are exempt from monitoring for radioactive substances according to Council Directive 2013/51/EURATOM, this study focuses on the radiological characterization of natural mineral water under Spanish Royal Decree 3/2023. The water studied was taken from Catalan aquifers with different lithological characteristics (sedimentary, metamorphic or granitic) and is sold on local markets. Moreover, radiological data on the water was correlated with its lithological origin and the health risk for different age groups was assessed. Our results showed that of the 26 natural mineral waters studied, 10 exceeded gross alpha screening value (100 mBq/L), all from granitic aquifers. Further research on natural individual radionuclides was conducted on these ten samples.

Evaluating boron levels in Turkish mineral waters: a comparative study of three analytical techniques
Turkey is abundant in natural mineral water sources, thanks to its location on the Alpine-Himalayan belt. Natural mineral water is drinking water characterized by its natural mineral, trace elements, and carbon dioxide content. Because of quite insufficient data, the boron content in bottled natural mineral waters in Turkey was analyzed by three different methods and compared: inductively coupled plasma mass spectrometry technique, carminic acid, and azomethine-H methods, in this study. The boron levels in mineral waters ranged from a minimum of 0.05 mg/L to a maximum of 8.61 mg/L. It was also safe by the upper limit level estimated by the World Health Organisation. As boron plays a beneficial role in human physiology, consuming natural mineral water may offer a positive contribution to public health by supporting boron intake in our country. The other outcome of our research was that the spectrophotometric carminic acid method can yield results similar to those obtained using the inductively coupled plasma mass spectrometry technique since the boron level of Turkish mineral water was within the limits level of the carminic acid method. However, the result of the azomethine-H method was found not to be suitable. Cross-sensitivity with other elements in mineral water might have caused this.

Balneotherapy using thermal mineral water baths and dermatological diseases: a systematic review
Balneotherapy includes practices and methods using medically and legally recognized mineral-medicinal waters, muds and natural gases from natural springs for therapeutic purposes. One of the most widely used method in balneotherapy is bathing with thermal mineral water. In the course of the years, scientific community has produced an increasing number of evidences that this practice is an effective method for treating signs and symptoms of several pathologies such as rheumatic, cardiovascular and dermatological diseases. This systematic review is aimed at evaluating the effect of balneotherapy with thermal water baths as a treatment to manage signs and symptoms of patients affected by all types of dermatological diseases. The systematic review was conducted according to the PRISMA Statement, and its protocol was registered on PROSPERO platform (CRD42022295913). The research was performed on the databases Pubmed, Scopus, Web of Science and Cochrane. We included clinical trials evaluating the effects of balneotherapy using thermal mineral water baths for managing dermatological diseases in humans, published in English and Italian language. Eight studies were included, seven of them enrolled adults affected by psoriasis and one studied atopic dermatitis patients. The common result of all the articles included was a clear improvement of signs and symptoms of psoriasis and eczematous diseases after use of thermal mineral water baths. These effects seem to be strictly related to physical and chemical properties of thermal water used for balneotherapy. However, studies in this field are still limited to support robust evidence of the effectiveness of balneotherapy using thermal mineral water baths and often their quality is low. Thus, new clinical studies need to be carried out, using more correct methods for conducting the studies and for processing statistical data.

Radon concentration in self-bottled mineral spring waters as a possible public health issue
Since 2013, the Council Directive 2013/51/Euratom has been regulating the content of radioactive substances in water intended for human consumption. However, mineral waters are exempted from this regulation, including self-bottled springs waters, where higher radon concentration are expected. Therefore, a systematic survey has been conducted on all the 33 mineral spring waters of Lazio (a region of Central Italy) in order to assess if such waters, when self-bottled, may be of concern for public health. Waters have been sampled in two different ways to evaluate the impact of bottling on radon concentration. Water sampling was possible for 20 different spring waters, with 6 samples for each one. The results show that 2 (10%) of measured mineral spring waters returned radon concentrations higher than 100 Bq L
−1
, i.e., the parametric value established by the Council Directive. These results, if confirmed by other surveys involving a higher number of mineral spring waters, would suggest regulating also these waters, especially in countries like Italy for which: (
i
) mineral water consumption is significant; (
ii
) mineral concession owners generally allow the consumers to fill bottles and containers, intended for transport and subsequent consumption, directly from public fountains or from fountains within the plant; (
iii
) the consumers’ habit of drinking self-bottled mineral water is widespread.
