“…In many buildings, moisture or condensate penetrates wall cavities or other hidden areas associated with the main airspace. This contributes to the fact that mold spores effectively enter the main room [20], as most fungal spores have a diameter of less than 10 μm, and cracks and gaps, as well as internal wall cavities, even at minimum sizes, usually exceed 1 mm. This is fully confirmed by the conclusion about the penetration of particles of different sizes (Figure 2) [21].…”

Introduction. Today there is an urgent need to create regulations governing the level of microorganisms in the air of office premises. This problem in Ukraine did not attract as much attention as it did now, during the COVID-19 pandemic. In other countries, on the other hand, it has not only been the subject of researches for the past 20 years, but has also introduced certain sanitary rules that employers must follow. In particular, according to research conducted in the United States, indoor air pollution is one of the five most dangerous factors for human health. The most important component that determines the safety and suitability of air is its microbiome, which may contain both pathogenic microorganisms and microorganisms that are not dangerous, but can cause adverse reactions: allergies, immune system stress and more. The purpose of the study is to analyze the literature and regulatory framework in Ukraine and other developed countries regarding the hygienic regulation of microbiological condition of office air. Materials and methods of research. Analytical review of scientific publications was carried out using scientometric databases, sanitary legislation of developed countries, periodicals and publications. Results. In the USA, the EU, Japan, Brazil and many other developed countries of the world there are hygienic standards that regulate the permissible limits of the number of microorganisms in the air of office premises. It should be noted that these regulations have significant differences in methodological approaches to risk assessment and criteria. Basically, from 250 to 1000 colony-forming units/m 3 are allowed for bacterial microflora and fungi according to the standards of different countries and organizations. Literature data show a significant correlation (r = 0.35-0.40) between the concentration of microorganisms (bacteria and fungi) in indoor air and microclimate parameters, which may be the basis for improving prevention measures. In Ukraine today, the regulatory framework for the number of microorganisms in the air applies only to premises in health care facilities or premises in the production of pharmaceutical products or food businesses. At the same time, regulations on administrative or office space that would provide safe limits for the presence of microorganisms in their air -have not been developed and implemented in health care practice. Conclusions. There is a significant need to develop sanitary and anti-epidemic rules for work in office premises in Ukraine, which, in particular, regulates the number of microorganisms (bacteria and fungi) in the air. To address this issue, the scientific and regulatory experience of the EU, the US and other developed countries in regulating the permissible concentration of microorganisms in office air can be very useful. Also, it is very important to consider not only the quantitative but also the qualitative composition of the microbial environment that can affect the human body. When developing preventive measures, it is quite appropriate to de...

“…For instance, Muise et al have indicated that fungal and mould spores can enter electrical wall services as a result of air leakage (Muise, Seo, Blair, & Applegate, 2010). It has also been demonstrated that building enclosures that increase the level of air tightness can reduce the number of contaminants in an occupied space when coupled with low flow continuous ventilation.…”

“…Breda et al (2010) recorded that the rheumatic diseases (inflammation and stiffness in muscles, joints, or fibrous tissues) are exacerbated by indoor environmental conditions, including dampness and fungi infestation. Rheumatoid arthritis, ankylosing spondylitis, Sjogren's syndrome, and psoriatic arthritis have been observed among occupants in water-damaged buildings with mould growth (Muise et al 2010).…”

Outbreaks of building-related illnesses, collectively termed as sick building syndrome (SBS) among building occupants reported in the recent decades, draw remarkable resemblance to early events of epidemic hysteria. Tarantism, the dancing mania of peasant women (animal-like squealing, obscene shouting, laughing, or weeping) during the fifteenth to seventeenth century, St. John's or St. Vitus' dances in Northern Europe, the hysterical fits of women due to smells from hemp steeped in water (Ramazzini 1713), industrial outbreak among workers in a cotton mill in the eighteenth century England (Gentleman's Magazine 1787), are historically recorded events. Many other early psychogenic illnesses reported from schools, hospitals, prisons, and in warfare, exemplify the results of various reasons, like prominent social concerns and exposure to physical, biological, or chemical agents (Bartholomew and Wessely 2002; Sirois 2013). The SBS manifests as the complex spectrum of ill health symptoms, such as mucous membrane irritation (rhinorrhea, nasal congestion, sore throat, eye irritation), asthma symptoms (chest tightness, wheezing), neurotoxic effects (a headache, fatigue, irritability), gastrointestinal disturbance, skin dryness, sensitivity to odours. These symptoms may appear among occupants in office buildings, schools, public buildings, hospitals, and recreational facilities. The rapid spread of symptoms often leads to the virtual closure of the facility, and resolution of the illness also takes place within a short time after leaving the facility (Laumbach 2008; Takeda et al. 2009). Building-related illnesses have been viewed as ubiquitous in modern high-rise buildings. These are designed to be airtight on energy-saving considerationwindows remain sealed, deprived of natural ventilation and daylighting, and HVAC system re-circulates the air in the building, with the minimal replacement of fresh air. Concerns about human health due to deteriorating indoor environmental quality are steadily increasing with a public outcry among the building occupants and also
