Special Issue Information

Dear Colleagues,

The nexus between indoor environmental quality and human health has been gathering more and more attention, especially during the COVID-19 pandemic when most of the infections occur indoors. The infected people release the infectious aerosols which contain SARS-CoV-2 viruses in indoor air. Some measures for enhancing indoor air quality, in particular those reducing indoor airborne particles, are potentially effective in reducing the aerosol transmission of viruses. Ventilation can effectively dilute the indoor-originated indoor pollutants, such as formaldehyde, volatile organic compounds, and pathogens of infectious diseases, and it is recommended to increase ventilation in order to prevent the indoor transmission of COVID-19. However, ventilation sometimes brings in the outdoor air, with unfavorable temperature, humidity, and outdoor pollutants, if the outdoor air is not well treated before introducing it indoors. The link between the air quality and the infection risk has made it possible to use bioeffluents, such as CO2 concentration, as indicators for the estimation of the infection risk in buildings. Even though measures to improve indoor air quality generally reduce the infection risk of COVID-19, some disinfection or cleaning measures potentially bring in unfavorable by-products such as ozone to occupied spaces, threatening human health. Beyond indoor air quality, evidence shows that indoor environment parameters, such as temperature, relative humidity, and lighting, also play important roles in determining the infectivity of the virus, thus impacting human health during the pandemic. Hence, the COVID-19 pandemic has brought the relationship between indoor environment quality and human health to the fore again, and a better understanding of this topic is required.

This Special Issue of Atmosphere will collect research efforts exploring the relationship between indoor environment quality and human health in the context of the COVID-19 pandemic. We invite studies of both the change of indoor environmental quality due to COVID-19 measures and the impact of indoor environmental quality on COVID-19 transmission. Studies can be based on laboratory and climate chambers, field monitoring, simulation, and surveys. We also welcome review and position papers.

The SARS-CoV virus spreads in the atmosphere mainly in the form of aerosols. Particle air filters are widely used in indoor heating, ventilation, and air-conditioning (HVAC) systems and filtration equipment to reduce aerosol concentration and improve indoor air quality. Requirements arise to rate filters according to their mass-based filtration efficiency. The size distribution of test aerosol greatly affects the measurement results of mass-based filtration efficiency and dust loading of filters, as well as the calibration of optical instruments for fine-particle (PM2.5) mass concentration measurement. The main objective of this study was to find a new method to generate a chemically nontoxic aerosol with a similar particle size distribution to atmospheric aerosol. We measured the size distribution of aerosols generated by DEHS (di-ethyl-hexyl-sebacate), PSL (poly-styrene latex), olive oil, and 20% sucrose solution with a collision nebulizer in a wide range of 15 nm–20 μm. Individually, none of the solutions generated particles that share a similar size distribution to atmospheric aerosol. We found that the 20% sucrose solution + olive oil mixture solution (Vss:Voo = 1:2) could be used to generate a chemically nontoxic aerosol with similar particle number/volume size distribution to the atmospheric aerosol (t-test, p < 0.05). The differences in the mass-base filtration efficiency measured by the generated aerosol and the atmospheric aerosol were smaller than 2% for MERV 7, 10, 13, and 16 rated filters. The aerosol generated by the new method also performed well in the calibration of optical-principle-based PM2.5 concentration measurement instruments. The average relative difference measured by a tapered element oscillating microbalance (TEOM) and a Dusttrak Model 8530 (calibrated by aerosol generated by the new method) was smaller than 5.8% in the real-situation measurement.
