AI Article Synopsis
- The study investigated the bactericidal and fungicidal effectiveness of ozonated water according to standard testing guidelines (EN 1040 and EN 1275) using various clinical strains, including multidrug-resistant bacteria.
- The research utilized a prototype device for intraoperative ozone therapy that demonstrated high ozone concentrations capable of killing most tested bacterial and yeast strains within 30 seconds, with some exceptions for fungal spores.
- The findings confirmed that the ozonated water produced met the required standards for antimicrobial activity, suggesting its potential use for tissue protection against infections during surgeries.
Article Abstract
Background: The purpose of this study was to analyze basic bactericidal and fungicidal activity of ozonated water according to EN 1040 "Chemical disinfectants and antiseptics--Quantitative suspension test for the evaluation of basic bactericidal activity of chemical disinfectants and antiseptics" and EN 1275 "Chemical disinfectants and antiseptics--Quantitative suspension test for the evaluation of basic fungicidal or basic yeasticidal activity of chemical disinfectants and antiseptics" with additional clinical multidrug-resistant bacterial strains and evaluate whether the ozonated water acts as a rapid and efficient antimicrobial agent and as such could be applied during intraoperative ozone treatment for tissue protection against infection with pathogenic bacteria.
Material/methods: A prototype device for intraoperative ozone therapy was used. Besides standard bacterial and fungal strains, 60 clinical bacterial isolates were analyzed.
Results: The ozone concentration in ozonated water was sufficient to kill almost all cells of the bacterial and yeast strains tested after 30 seconds. Effective action against Aspergillus brasiliensis spores required a longer time than those required in the case of bacterial cells or vegetative cells of yeast.
Conclusions: The prototype device used in our study produced high ozone concentrations in freshly prepared ozonated water. This liquid complied with the requirements of the EN Standards: basic bactericidal and basic yeasticidal activities.

As the global consumption of pharmaceuticals increases, so does their release into water bodies. The effects, although not fully understood, can be detrimental to aquatic ecosystems and human health. The new Urban Wastewater Treatment Directive (UWWTD) in European Union requires implementation of quaternary wastewater treatment processes to limit the loads of pharmaceuticals reaching water bodies.

Comorbidities related to cardiovascular disease (CVD) and environmental pollution have emerged as serious concerns. The exposome concept underscores the cumulative impact of environmental factors, including climate change, air pollution, chemicals like PFAS, and heavy metals, on cardiovascular health. Chronic exposure to these pollutants contributes to inflammation, oxidative stress, and endothelial dysfunction, further exacerbating the global burden of CVDs.

Technical and economic criteria were used to evaluate the feasibility of the treatment of an industrial effluent (10 m/h) for water recovery and reuse. The treatment evaluation included the following: (1) effluent characteristic determination; (2) selection and evaluation of the effluent treatment at lab scale, establishing operating conditions and process efficiency; (3) scaling up the treatment process to the industrial level; (4) treatment plant design and commercial availability analysis of the required equipment; and (5) the costs of the inversion and operation of the plant treatment, cost/m for water recovery, and time of investment recovery. The physicochemical characteristics of the effluent exposed the polluted wastewater with sodium chloride salts and colourants, predominating a mixture of tartrazine, Red 40, and brilliant blue from the synthesis of food additives.
