Research SummariesPortable HEPA air cleaners can complement asthma education programs and be part of an effective overall strategy to reduce asthma triggers in the bedrooms of children with asthma. Indoor Air
Emissions from a residence and its furnishings were comparable in magnitude to emissions from occupants and occupant activities (e.g. cooking and cleaning). Indoor Air
This study used advanced instruments to study hundreds of volatile organic compounds (VOCs) in two homes over time. Acrolein, acetaldehyde, and acrylic acid concentrations were above chronic advisory health guidelines. Environmental Science & Technology
This study used silicone wristbands to passively measure exposure to semi-volatile organic compounds (sVOCs) in office buildings across several countries. They found office workers exposed to several banned substances including PBDEs, certain pesticides, and PCBs. Environment International
Air cleaners generating hydroxyl radicals can contribute to the formation of secondary organic aerosol (SOA), a known health hazard. Environmental Science & Technology Letters
Burning candles can have a negative impact on indoor air quality, especially when air movement creates a flame disturbance. Indoor Air
Residential oven use resulted in elevated levels of siloxanes, a concerning class of chemicals, likely due to silicone materials inside the oven. Environmental Science & Technology Letters
PM2.5 may be an important index of workers’ satisfaction with COVID-19 countermeasures and productivity. Indoor Air
Portable HEPA air cleaners can reduce exposure to viral aerosols in indoor environments, especially when combined with universal masking. CDC MMWR
The concentration of SARS-CoV-2 recovered on residential HVAC filters may be a useful tool for estimating airborne levels in homes. Science of The Total Environment
Fine respiratory aerosols (≤5μm) emitted by COVID-19 patients when talking and singing contain more SARS-CoV-2 copies than coarse aerosols (>5μm). PrePrint
The amount of virus that transferred from a contaminated object to a finger (and vice-versa) was estimated to be around 20%, but it depended on the type of virus, surface, and other factors. PrePrint |
