“…Both samples C and D, which were made of cotton as the main material, had TVOC concentrations below 460 µg m –3 . These TVOC concentration levels corresponded to a level that is harmless to the human body (no relevant health-related concerns, TVOC < 1000 µg m –3 ) ( der Ad-hoc-Arbeitsgruppe, 2007 , Fromme et al, 2019 , Salthammer, 2022 ). In the case of sample E, the TVOC concentrations of E2 and E3 were relatively high at 1330 ± 259 µg m –3 and 1036 ± 204 µg m –3 , respectively.…”

“…Shrubsole et al concluded that individual VOC guidelines are more appropriate than the TVOC guideline s [ 24 ]. According to Salthammer, T., TVOC cannot be used for health and odor-related issues [ 25 ]. Some investigators argue that health-related effects of air quality should be assessed using specific VOCs rather than TVOC, as TVOC does not reveal the toxicity of individual VOCs to humans [ 26 , 27 ].…”

Is indoor environment a risk factor of building-related symptoms?

et al. 2023

The indoor environment, particularly indoor air quality (IAQ), is significantly associated with building-related symptoms (BRSs) in humans. In our previous studies, we demonstrated a significant relationship between BRSs and indoor chemical concentrations. In Japan, the Ministry of Health, Labor, and Welfare (MHLW) guideline recommends an air quality target of 13 volatile organic compounds (VOCs) and a provisional target of 400 μg/m3 for total VOCs (TVOC). The objective of this study was to determine the relationship between TVOC levels and the risk of BRSs using the Japanese provisional target TVOC level of 400 μg/m3. The relationship between odor intensity and BRSs while the TVOC levels were under 400 μg/m3 was also examined. The study was conducted in a laboratory house (LH) on the campus of Chiba University from 2017–2019. The study included 149 participants who spent 60 minutes in the LH. The participants were asked to evaluate the IAQ of the LH. A significant relationship between the risk of BRSs and the provisional target TVOC level was observed (odds ratio: 2.94, 95% confidence interval: 1.18–7.35). Furthermore, a significant relationship between odor intensity and risk of BRSs in spaces with TVOC levels less than 400 μg/m3 was detected (odds ratio: 6.06, 95% confidence interval: 1.21–30.44). In conclusion, the risk of BRSs is significantly lower in spaces with low TVOC levels and low odor intensity. Reducing the concentration of airborne chemicals and odor intensity may improve IAQ and prevent BRSs.

“…Another parameter that can be measured easily and quickly is the sum of volatile organic compounds as the so-called TVOC PID value [75]. TVOC stands for “Total Volatile Organic Compounds” [76] and PID for the measurement method using photoionization. However, TVOC PID is not directly linked to the population density and the breathing rate of people, so that this parameter should at best be used in addition to the CO 2 concentration.…”

Requirements to minimize airborne infections related to virus aerosol contamination at indoor cultural events

The SARS-CoV-2 pandemic has resulted in many live events being canceled or held without spectator participation. It is therefore necessary to develop strategies to determine the conditions under which cultural activities can be maintained. In this study the results from available literature were combined with findings, guidelines and regulations for other indoor environments and recommendations were derived. In the cultural sector, the number of experimental investigations, surveys and simulations is comparatively small. This is probably due to the complexity of the events in terms of location and visitor flow, so the respective conditions under which they take place can be very different. It is therefore practically impossible to predict the risk of infection for a specific situation with potential virus spreaders attending or to derive general rules that go beyond the known measures of vaccination, testing, masks and distance. Cultural events can be held under pandemic conditions, provided certain conditions are met. Most study results agree on this. However, any recommendations for hygiene, safety and ventilation measures in cultural institutions can only minimize the risk of infection, but cannot completely rule it out. It is also of considerable importance that visitors protect themselves individually and act responsibly.
