“…A database compiling indoor concentrations in office buildings was developed by including the results from 69 studies 19,21,25‐91 . Of these, 12 are reports from the French air quality monitoring network 55‐59,63‐67,70,71 .…”

Indoor air pollutant health prioritization in office buildings

This work presents an original method to identify priority indoor air pollutants in office buildings. It uses both a chronic risk assessment approach by calculating a hazard quotient, and a hazard classification method based on carcinogenic, mutagenic, reprotoxic, and endocrine disruptive effects. A graphical representation of the results provides a comprehensive and concise visualization of all of the information, including the number of buildings where each substance was measured, an indicator of exposure data robustness. Seventy-one out of 342 substances (20%) for which indoor air concentrations have already been measured in office buildings were identified as priority pollutants. The results were compared to previous prioritization studies in various types of indoor environments to assess the reliability of the method and highlight its advantages. Sensitivity analyses were performed to reduce the geographical scope (OECD countries only), time scope (after 2010 only), and measurement duration (working hours only) and showed little influence on the results. Finally, 123 additional substances that could be present in office indoor air but could not be assessed due to the lack of measurement data are proposed for future monitoring surveys to update the prioritization of indoor air pollutants in offices.

“…This may occur because these public places contained few PAH sources. The second-highest concentration level (39.58–155.11 ng/m 3 ) was observed in hotels in Jinan (China) in public bars in Warri (Nigeria) and in office buildings in Changchun (China) [ 100 , 101 , 102 ]. The higher concentration of PM-bound PAHs in hotels in Jinan than that in hotels in Jeddah possibly occurred due to the local background urban concentrations, and is consistent with the results for Beijing and Jeddah [ 88 , 89 ].…”

“…The relatively high concentration in public bars may be the result of factors such as tobacco smoking, while in office buildings, this may occur due to emissions from machines such as printers [ 103 ]. The seasonal differences observed in office buildings may occur due to the gaseous/particles phase distribution of PAHs at different temperatures and various outdoor pollution sources via window opening or ventilator operation [ 102 ]. The highest concentration level (550–39,000 ng/m 3 ) was observed in fire stations, ships, and Chinese kitchens [ 83 , 84 , 104 ].…”

Particulate matter (PM) is a major factor contributing to air quality deterioration that enters the atmosphere as a consequence of various natural and anthropogenic activities. In PM, polycyclic aromatic hydrocarbons (PAHs) represent a class of organic chemicals with at least two aromatic rings that are mainly directly emitted via the incomplete combustion of various organic materials. Numerous toxicological and epidemiological studies have proven adverse links between exposure to particulate matter-bound (PM-bound) PAHs and human health due to their carcinogenicity and mutagenicity. Among human exposure routes, inhalation is the main pathway regarding PM-bound PAHs in the atmosphere. Moreover, the concentrations of PM-bound PAHs differ among people, microenvironments and areas. Hence, understanding the behaviour of PM-bound PAHs in the atmosphere is crucial. However, because current techniques hardly monitor PAHs in real-time, timely feedback on PAHs including the characteristics of their concentration and composition, is not obtained via real-time analysis methods. Therefore, in this review, we summarize personal exposure, and indoor and outdoor PM-bound PAH concentrations for different participants, spaces, and cities worldwide in recent years. The main aims are to clarify the characteristics of PM-bound PAHs under different exposure conditions, in addition to the health effects and assessment methods of PAHs.

“…20–22 Especially when there is no apparent indoor source, indoor and outdoor PM 2.5 levels are highly correlated. 23 At the same time, common human activities, for example, smoking and cooking are the main indoor sources of PM 2.5 . 24,25 For some rural families, biomass burning in the autumn and winter could also generate various levels of PM 2.5 , 26 exacerbating indoor air pollution.…”

“…Based on studies of high-rise buildings, when analysing their indoor PM 2.5 and metallic element distribution patterns, the indoor PM 2.5 concentrations were found to be lower in rooms on higher floors, 35 but these were not correlated with the area or volume of the room. 23 Meanwhile, metal components of PM 2.5 show some degree of vertical distribution in the indoor environment of high-rise buildings. In particular, the concentration of the element Arsenic (As) is strongly positively correlated with the floor level, while other elements’ concentrations show negative correlations.…”
