Research SummariesHigher PM2.5 and CO2 concentrations were associated with slower response times and reduced accuracy in office workers. Environmental Research Letters
This review study concluded that total spore counts via spore traps are not a consistently reliable method for identifying dampness in a single house (but Penicillium/Aspergillus counts showed a stronger signal). Journal of Exposure Science & Environmental Epidemiology
Homes receiving an intervention of continuous balanced ventilation with an energy recovery ventilator and improved filtration had the best indoor air quality improvements. Science of The Total Environment
Air cleaners that introduce new chemical agents or initiate complex chemistry can result in the release of reactive intermediates and/or byproducts into the indoor environment. Environmental Science & Technology 
Cases of Legionnaires’ Disease in the Netherlands were more likely to be from residents living near wastewater treatment plants. International Journal of Hygiene and Environmental Health
Personal exposures to volatile organic compounds were greatest at home when compared to other indoor environments, within vehicles, and outdoors. Sensors
Indoor swimming pools run the risk of producing hazardous chlorine gas when disinfectants mix with certain pH reducers. JOEH
Early age exposure to moisture and mold is related to a marker for lung inflammation at age 6. Pediatric Allergy and Immunology
This study evaluated the survival of SARS-CoV-2 on N95 respirators and found that 99% of viable virus was inactivated after 5 days, with relative humidity being a key variable. JOEH
In a hospital, airborne SARS-CoV-2 was highest in rooms with COVID-19 infected patients and in corridors adjacent to these rooms. Environmental Research 
This study found that current ventilation standards are unlikely to control the spread of airborne contagious viruses with high emission rates. Geoscience Frontiers
High volume air sampling for SARS-CoV-2 was more successful as a surveillance method compared to surface sampling. Indoor Air
Expression of the SARS-CoV-2 cell entry receptor (ACE2) was highly variable between individuals. Science Advances |
