Impacts of Indoor Air Quality on Working‐Age Populations' Subjective Well‐Being: Evidence From China Labor Dynamics Survey

ABSTRACTOutdoor air pollution can affect physical labor productivity and mental health, but it remains to be studied how indoor air quality (IAQ) exposure affects working‐age populations' subjective well‐being and physical health. Here, the first evidence of a link between IAQ and the subjective well‐being of working‐age populations has been provided using the dataset from a longitudinal survey in China. Using household ventilation as an instrument variable (IV) of IAQ revealed that IAQ improvements increased working‐age populations' subjective well‐being and life satisfaction by significantly affecting their physical health. Our analysis shows that an increase in IAQ by one standard deviation improves working‐age populations' subjective well‐being by 0.041 standard deviations. The marginal willingness to pay for IAQ is approximately 98.09 CNY. Compared with outdoor air quality, the impact of IAQ on well‐being and life satisfaction is more conspicuous. The results are robust to a variety of alternative specifications. For developing countries, improving IAQ is a new channel toward enhancing life quality, with lower economic and social costs.

Ventilation Strategies to Mitigate Air Pollution Impact on Hospital Professionals in Intensive Care Units in the Democratic Republic of Congo

This study critically examines the impact of indoor air quality (IAQ) on occupant health in two critical care units (ICUs) at Jason Sendwe Hospital (JSH) and General Carrier de Mine Hospital (GCMH) within the Southern DRC metropolitan area, focusing on their impact on occupant health and well-being. Utilizing a mixed methods approach that includes health questionnaires, continuous environmental monitoring (monitoring CO2, VOCs, PM2.5, PM10, temperature, and relative humidity), and computational fluid dynamics (CFD) analysis, this research aims to identify correlations between environmental factors and the health of hospital staff and patients. The investigation was conducted across both the rainy and dry seasons, revealing significant seasonal variations in IEQ parameters and exploring the incidence of symptoms commonly associated with sick building syndrome among hospital staff. Higher CO2, VOCs, and particulate matter levels during the dry season indicated the inadequacy of current ventilation strategies to maintain optimal air quality. This study proposes the implementation of air filtration and purification systems and the refurbishment of natural ventilation systems as effective measures to improve IAQ. Additionally, alternative ventilation strategies, including occupancy reduction and the integration of supply and exhaust ventilation, were explored to address the challenges of inadequate ventilation. The findings reveal the urgent need for hospitals to adopt ventilation strategies that ensure the health and well-being of occupants, highlighting the importance of continuous IAQ monitoring, community engagement, and the integration of advanced ventilation technologies in healthcare settings. This comprehensive exploration offers valuable insights for improving ventilation in ICUs, contributing to creating healthier indoor environments in hospital settings, especially in regions facing unique environmental challenges.

Home indoor air quality and cognitive function over one year for people working remotely during COVID-19

The coronavirus disease 2019 (COVID-19) pandemic triggered an increase in remote work-from-home for office workers. Given that many homes now function as offices despite not being designed to support office work, it is critical to research the impact of indoor air quality (IAQ) in homes on the cognitive performance of people working from home. In this study, we followed 206 office workers across the U.S. over one year under remote or hybrid-remote settings during 2021–2022. Participants placed two real-time, consumer-grade indoor environmental monitors in their home workstation area and bedroom. Using a custom smartphone application geofenced to their residential address, participants responded to surveys and periodic cognitive function tests, including the Stroop color–word interference test, Arithmetic two-digit addition/subtraction test, and Compound Remote Associates Task (cRAT). Exposures assessed included carbon dioxide (CO2) and thermal conditions (indoor heat index: a combination of temperature and relative humidity) averaged over 30 min prior to each cognitive test. In fully adjusted longitudinal mixed models (n ≤ 121), we found that indoor thermal conditions at home were associated with cognitive function outcomes non-linearly (p < 0.05), with poorer cognitive performance on the Stroop test and poorer creative problem-solving on the cRAT when conditions were either too warm or too cool. Most indoor CO2 levels were <640 ppm, but there was still a slight association between higher CO2 and poorer cognitive performance on Stroop (p = 0.09). Our findings highlight the need to enhance home indoor environmental quality for optimal cognitive function during remote work, with benefits for both employees and employers.

Impact of Indoor Air Quality and Multi-domain Factors on Human Productivity and Physiological Responses: A Comprehensive Review

Indoor environmental quality (IEQ) significantly impacts human health, well-being, and productivity. However, a comprehensive and in-depth review of the combined effects of IAQ and other multi-domain factors on human productivity is lacking. There has not been any prior review that encapsulates the impact of multi-domain factors on productivity and physiological responses of occupants. To address this gap, this review paper investigates and highlights the impact of IAQ and multi-domain factors (thermal, visual, and acoustic) on human productivity and occupant well-being in the built environment. The review explores various research methods, including evaluation of human productivity and creativity, data collection, and physiological signal analysis. We also examined the interactions between IAQ and multi-domain factors, as well as strategies for optimizing productivity through integrated building design and smart systems. The key findings from this review reveal that IAQ significantly impacts human productivity and occupant well-being, with interactions between IAQ and other IEQ factors further impacting these effects. Despite advances in the field, there are several limitations and gaps in the current research methods and study designs, including small sample sizes, limited and insufficient experimental design and control, reliance on laboratory or simulated environments, lack of follow-up and long-term data, and lack of robust performance metrics. The review proposes future research directions, including specific applications, and follow-up work to address these limitations and further advance the understanding of IAQ and multi-domain factors in the built environment. The implications of this review for policy and practice include the need for holistic and integrated approaches to IAQ and IEQ management, with a focus on creating healthy and productive indoor environments. This review emphasizes the importance of considering the complex interplay between IAQ and multi-domain factors, as well as the potentials of adopting smart control systems and sustainable design strategies to optimize productivity and occupant well-being in the built environment. By addressing these critical issues, we can enhance the overall quality of life for building occupants and contribute to a more sustainable future.

INVESTIGATING INDOOR AIR QUALITY IN TRAINING ROOM ENVIRONMENTS OF A TECHNICAL UNIVERSITY SPORTS FACILITIES

Air quality analyses were conducted in sports facilities at the Silesian University of Technologyin Poland, with specific focus on training rooms occupied by students. The study aimed to assessthe impact of indoor air quality (IAQ) on human health, taking into consideration variousventilation methods and the number of individuals exercising indoors. Air samples were collectedfrom five training rooms in three sports facilities. The results indicate that outdoor air primarilyinfluences air quality in sports facilities. Internal factors, such as the number of students, floorsurfaces and mattresses, influenced pollutant concentrations (CO2 and PM2.5). Overall, CO2 levelsremained within safe limits, but fluctuations occurred due to physical activity, reaching as high as1859.7 ppm. The average median concentration of indoor PM2.5 was 16.7 μg/m, while outdoorlevels averaged 12.2 μg/m. A correlation between indoor and outdoor PM2.5 pollution underscoresthe importance of using air purifiers to enhance air quality in sports halls.

Inverted core–shell structured hollow particles for improved volatile organic compounds removal and photocatalytic regeneration

As the amount of time people spend indoors increases, the impact of indoor air quality on health has become more important, and numerous studies have been conducted to eliminate indoor air pollutants such as volatile organic compounds (VOCs). Among the several methods for removing VOCs, the adsorption is the most widely used in that it requires a simple mechanism and low energy, but has a limitation in that it is difficult to regenerate after saturation. In order to solve this problem, composite materials combining adsorbents and photocatalysts have been developed, but there is still an issue that the photocatalytic activity can be lowered by covering the surface of the photocatalyst with the adsorbent. Here, mesoporous carbon/silica/titania double shell hollow nanoparticles (MC/SiO2/TiO2 HNPs) are prepared through etching, calcination and carbonization of polystyrene/polyacrylonitrile/SiO2/TiO2 multi-layered core/shell nanoparticles. Attributed to the high specific surface area of the MC/SiO2/TiO2 HNPs, high VOCs adsorption efficiency can be achieved. Moreover, the photocatalytic activity can be maximized since the TiO2 shell is exposed to the surface without any covering materials.

Physicochemical Quality of Oyster Mushroom for Functional Food

This article presents studies on the physicochemical quality of oyster mushrooms grown within a housing and controlled by the Internet of Things (IoT). The goals of this study were to assess (1) the impact of indoor air quality on the growth and quality of mushrooms and (2) the antioxidant content of oyster mushrooms. In this study, the air temperature and humidity of oyster mushroom house per unit time was recorded and controlled automatically by an IoT system. Additionally, their physicochemical and microbiological quality were evaluated using physico-analytical instruments, and the potency of their ergothioneine (EGT) content was investigated using the HPLC method. The temperature of the air inside was between 29 and 35 °C, and the relative humidity was between 60% and 90%. The average texture of mushroom is soft. The average length, width, and height of the fresh mushroom were 41.5 mm, 60.0 mm, and 29.5 mm, respectively. The microbiological test confirmed that there was no salmonella infection in the collected mushrooms. The button-stage mushrooms have less total fungus than the bloom-stage mushrooms. The extraction standard method employs an EGT content of 0.674 mg/g as determined by chromatography data analysis. The oyster mushrooms can be consumed as a healthy meal, and the study of EGT showed also very prospective as one of immunotherapeutic food.

Experimental study on the impact of indoor air quality on creativity by Serious Brick Play method

Companies are increasingly asking their employees to find creative solutions to their problems. However, the office environment may reduce an employee’s creative potential. In this study, the role of indoor air quality parameters (PM2.5, TVOC, and CO2) in maintaining a creative environment (involving lateral thinking ability) was evaluated by Serious Brick Play (SBP), an adaptation of the LEGO Serious Play (LSP) framework. This study was conducted in a simulated office space with 92 participants over a period of 6 weeks. The SBP required participants to address a challenge by building using Lego bricks, and then describe the solution within a given timeframe. The creations and descriptions were then graded in terms of originality, fluency, and build. The results indicated that higher TVOC levels were significantly associated with lower-rated creative solutions. A 71.9% reduction in TVOC (from 1000 ppb), improves an individual’s full creative potential by 11.5%. Thus, maintaining a low TVOC level will critically enhance creativity in offices.

Impact of Indoor Air Quality and Breathing on Back and Neck Pain: A Systematic Review.

Back pain and neck pain are important public health concerns and are among the most common and disabling conditions globally. However, the relationships among indoor air quality (IAQ), breathing parameters (pulmonary function, respiratory disorders), and back pain and neck pain have not been adequately assessed. The purpose of this study was to systematically review the literature about the impact of IAQ and breathing parameters on back pain and neck pain (PROSPERO ID: CRD42022380515). CINAHL, EMBASE, PEDRo, and PubMed databases were searched through January 19, 2023. Inclusion criteria for study eligibility were observational studies (except case reports) or randomized controlled trials (RCTs), published in peer-reviewed journals in the English language, human research, original research, examined the relationships between IAQ, or breathing parameters with back pain or neck pain. Review procedures were conducted and reported according to PRISMA recommendations. Empirical evidence statements were developed for observational studies, and grades of evidence statements were developed for RCTs. Sixty-seven eligible studies were found (54 observational studies and 13 RCTs) that enrolled 345,832 participants. None of the studies assessed the combined impact of IAQ and breathing parameters on back pain or neck pain. No level 1 studies were found, which precludes making strong statements about causality and strong recommendations about the efficacy of IAQ and breathing exercise interventions for reducing pain and disability related to back pain and neck pain. Evidence indicates that poor IAQ and respiratory disorders are related to an increased risk of back pain and neck pain. Conflicting evidence exists about the association between pulmonary function with back pain and neck pain. Evidence for breathing exercise interventions was mixed with numerous limitations. This review provides preliminary evidence on the relationships of IAQ and breathing parameters with back pain and neck pain, which can be used to guide future research and clinical implementation efforts. Assuming positive findings in subsequent research, a wide range of stakeholders involved with this complex human-building-environment interface can be equipped to address IAQ and breathingparameters, along with other established risk factors to help those suffering from back pain and neck pain.

Removal of volatile organic compounds by mobile air cleaners: Dynamics, limitations, and possible side effects

Air cleaners are becoming increasingly popular as a response to the increased focus on the impact of indoor air quality on human health, comfort and performance. In this study, the removal of particulate matter (PM) and volatile organic compounds (VOCs) by mobile air cleaners is investigated in an unoccupied university classroom. From time-resolved measurements by proton-transfer-reaction time of flight mass spectrometer (PTR-TOF-MS) the study reports on VOC removal and by-product formation from different air cleaning technologies. Results revealed an inconsistency between expected and experimentally obtained clean air delivery rates (CADRs). For seven out of eight air cleaners examined, the CADRs for all VOCs tested (methanol, acetaldehyde, acetone, acetic acid, isoprene, butanone, toluene, benzaldehyde and limonene) were significantly lower than the corresponding CADRs for PM. In general, single pass removal efficiencies (REs) for VOCs were found to decrease as a function of time. The VOCs demonstrated very distinctive dynamic behavior. Results indicated adsorption as the main removal mechanism of VOCs for all air cleaners for which a significant removal (RE ≥ 5%) was observed. Formation of by-products (incl. CH2O and C4H6O) was associated with technologies containing an UV lamp. Reemission of specific VOCs was observed for adsorption-based air cleaners during operation in a newly vented room. The results highlight the inadequacy of how we currently report air cleaner performance.

A Pilot Study on the Combined Multi-domain Impact of Indoor Air Quality and Noise on Office Productivity

As people spend 90% of their time indoors, it was necessary to improve indoor environmental quality to enhance human productivity. Indoor environmental quality consists of indoor air quality (IAQ), thermal, visual, and acoustic comfort. However, only a few studies have investigated the combined effects of IAQ and noise. During and after the COVID-19 pandemic, portable air cleaner is often used in buildings to reduce the concentration of particles in the air, but it also generates noise. The objective of this study is to determine the effects of a portable air cleaner on IAQ and noise level, and more importantly the resulting combined effects on office productivity. For this purpose, we conducted human subject tests in an office and each test lasted for 1.5h. For each case, the air temperature, relative humidity, and supply airflow rate were kept constant while the air cleaner was switched between on and off for various noise levels and IAQ. We recruited 7 participants and collected data on the concentration of CO2, particles, and TVOC every 5 minutes. We used wristbands to measure heart rate and skin electrodermal activity. And we used headbands to measure electroencephalogram (EEG) and facial activity. The questionnaire survey was used to learn the occupants’ responses to the indoor environment. To learn their productivity, occupants also did math addition tasks and typing tasks. We found that when using the portable air cleaner, the noise level raised from 55dB to around 70dB. The particle and TVOC concentrations were reduced by 90% and 20%, respectively. The questionnaire survey showed that the occupants felt unsatisfied due to noise. And the noise dissatisfaction exceeded the improved IAQ. By analyzing the EEG and the number of jaw clenches, the occupants felt more nervous and concentrated when the air cleaner was on. We confirmed the impact of noise and the combined impact of IAQ and noise on office productivity.

Evaluating the effects of indoor air quality on teacher performance using artificial neural network

PurposeA building's Indoor Air Quality (IAQ) has a direct impact on the health and productivity on its occupants. Understanding the effects of IAQ in educational buildings is essential in both the design and construction phases for decision-makers. The purpose of this paper is to outline the impact air quality has on occupants' performance, especially teachers and students in educational settings.Design/methodology/approachThis study aims to evaluate the effects of IAQ on teachers' performances and to deliver air quality requirements to building information modelling-led school projects. The methodology of the research approach used a quasi-experiment through questionnaire surveys and physical measurements of indoor air parameters to associate correlation and deduction. A technical college building in Saudi Arabia was used for the case study. The study developed an artificial neural network (ANN) model to define and predict relationships between teachers' performance and IAQ.FindingsThis paper contains a detailed investigation into the impact of IAQ via direct parameters (relative humidity, ventilation rates and carbon dioxide) on teacher performance. Research findings indicated an optimal relative humidity with 65%, ranging between 650 to 750 ppm of CO2, and 0.4 m/s ventilation rate. This ratio is considered optimum for both comfort and performanceOriginality/valueThis paper focuses on teacher performance in Saudi Arabia and used ANN to define and predict the relationship between performance and IAQ. There are few studies that focus on teacher performance in Saudi Arabia and very few that use ANN in data analysis.

Evaluation of indoor particulate matter and associated PAHs during the winter season in Northern India: A comprehensive impact of regional appearances

As population around the world is spending approximately 90% of their time indoors, monitoring of indoor air pollutants and their successive health risk assessment has become a prominent area of research and expertise. This paper puts forward the study conducted in a typical Indian city, Lucknow from November 2021 to February 2022 in three microenvironments namely industrial, commercial and residential. The study targets indoor air quality with an equivalent assessment of outdoor air quality as an analogy for proper evaluation. The study initiated with a questionnaire survey which was principally conducted to assess the impact of indoor air quality on children's health. On the basis of the survey result six households from three microenvironment were selected for both indoor and outdoor monitoring of PM>2.5, PM2.5, PM1.0-2.5, PM0.50-1.0, PM0.25-0.50 and PM<0.25, and polycyclic aromatic hydrocarbons (PAHs) associated with PM2.5. A remarkable powerful connection between Fluorene and Phenanthrene was obtained in residential households, which may be imputed to their release from combustion of oil, coal, wood, and other organic matter. Moreover, the incremental health risk assessment was performed on children with different age groups. The results obtained for all age group were high as compared to the USEPA standard prescribed for ILCR, however, children aged 1 to 3 years were evaluated to be most vulnerable among all. The outcomes of this study will be the first step in providing a superior understanding about the quality of air in a plethora of microenvironments. This would further aid to get an insight into the ill impacts of sub-micron particles with a better understanding to frame new guidelines for possible regulations.

Effects of covid-induced lockdown on inhabitants’ perception of indoor air quality in naturally ventilated homes

The intensified indoor living during the spring 2020 lockdown, with enhanced user awareness of the prevailing conditions in their homes, constituted a natural stress test for the housing design in place today. Surveys conducted during this period have yielded lessons for designing better intervention strategies for the residential sector, taking into account the systematic morphological and economic limitations of the buildings concerned. These considerations should inform the development of policies and strategies for improving environmental quality compatible with lower residential energy consumption and higher quality of life. This study explores the effect of occupant behaviour on home ventilation and the perception of the impact of indoor air quality on user health before and during lockdown. The method deployed consisted in monitoring environmental variables and conducting user surveys before and after restrictions came into force. The findings showed that prior to lockdown, occupants were unaware of or paid little heed to changes in indoor air quality, failed to perceive stuffiness, and, as a rule, reported symptoms or discomfort only at night during the summer months. During lockdown, however, users came to attach greater importance to air quality, and a greater sensitivity to odours and a heightened awareness of CO2 concentration prompted them to ventilate their homes more frequently. In the spring of 2020, occupants also indicated a wider spectrum of indisposition, in particular in connection with sleep patterns.

SAW-Based Differential Sensor Exploiting Metallocorroles Properties for Selective CO Measurement

During the last decades, the potential impact of indoor air quality on human health has stimulated an interest in hazardous compounds survey, such as carbon monoxide (CO). The detection of these compounds has consequently become a vital need. To address this issue, we propose a Surface Acoustic Wave (SAW) device functionalized with metallocorroles used for the selective detection of CO.Here, we insist on the necessity to detect CO in the presence of interferents, such as O2 that is obviously present in the air, carbon dioxide (CO2) present in significant quantity in urban area (400 ppm) and humidity (H2O) which is a well-known interferent in the case of SAW-based gas sensors.We will report on the interest of a differential configuration of the sensor that takes advantage of accurate organic layers, to improve the stability of the sensor’s signal and lower the sensitivity to interferents.Acknowledgments: this work was supported by the PIA-Excellence ISITE-BFC (CoMICS program 2019-2022: Chemistry of Molecular Interactions - Catalysis and Sensors) and the ISITE CO2DECIN.REFERENCES: [1] Di Natale, C.; Gros, C.

Influence of interfering gases on a carbon monoxide differential sensor based on SAW devices functionalized with cobalt and copper corroles

During the last decades, the potential impact of indoor air quality on human health has stimulated an interest in hazardous compounds survey such as carbon monoxide (CO). The detection of this compound has consequently become a vital need. To address this issue, we propose a Surface Acoustic Wave (SAW) device functionalized with metallocorroles used for the selective detection of CO. Here, we insist on the necessity to detect CO in the presence of interferents, such as O2 that is obviously present in the air, CO2 present in significant quantity in urban area (400 ppm) and humidity (H2O) which is a well-known interferent in the case of SAW-based gas sensors. We report the interest of a differential configuration of the sensor that takes advantage of accurate organic layers, to lower the sensitivity to outer parameters as well as interferents. The sensitivity of the sensor under various conditions and the repeatability of the measurements are finally shown to assess the efficiency of our device.

Field-based longitudinal study design for measuring the association between indoor air quality and occupant health status in residential buildings

There has been a growing interest in the association between indoor air quality (IAQ) with an increase in the time spent at home. However, there is still a lack of evidence on the impact of IAQ on occupants' health and well-being in the long term. This study aimed to develop a field-based longitudinal study design to evaluate the IAQ level and daily symptoms of adults and children living in different types of buildings over one year. We proposed vital principles to be considered when recruiting the study participants so that potential confounders, such as age, underlying diseases, and the geographic area would be either removed in advance or matched between different building types. We suggested collecting exposure and outcome data in three categories: lifestyle and housing environment, IAQ measurement, and occupants' health. We presented web-based survey tools for collecting housing and health data, and the frequency of data collection varied from weekly to six-month intervals. We developed two different models using a generalized mixed model for modeling the association between housing environment, IAQ, and human health. The current study design could be applied for future studies on the association between built environment and health, regardless of the type of buildings.•A real-time indoor air quality monitor was used to monitor indoor air parameters every 5 mins over one year.•A simple web-based survey tool was developed to collect data for occupants' daily symptoms in the long term.•A binomial generalized linear mixed model and a Poisson generalized linear mixed model was developed to evaluate the association between indoor air parameters, and building types and daily symptoms.
