Research SummariesBuildings can protect their occupants from outdoor particulate pollution. Protection increases with larger particle sizes (10 μm) compared to smaller (0.1 μm). Atmospheric Environment
In a study of domestic cleaners, the VOC with the greatest average concentration was d-limonene, a common additive in cleaning products. Journal of Occupational and Environmental Hygiene
Within one week of operating a portable ultrasonic humidifier to maintain 70% relative humidity, airborne bacteria concentrations exceeded 1,000 CFU/m3. Indoor Air
Indoor airborne bacteria were significantly different between three building types tested: commercial buildings, residences, and subways. Environmental Science & Technology
Facially applied personal care products, such as moisturizers, have the potential to deliver enhanced VOC doses via inhalation due to close proximity of the nose and mouth to the emission source. Indoor Air
Personal exposure to PM2.5 is not necessarily correlated to outdoor levels. Environmental Research
Elevated and hazardous levels of airborne particles and formaldehyde may be encountered following a structural fire. Journal of Occupational and Environmental Hygiene
No correlations between IAQ parameters could be associated with positive/negative SARS-CoV-2 samples. Journal of Occupational and Environmental Medicine
Persistent physical symptoms after COVID-19 infection should not be automatically ascribed to SARS-CoV-2. JAMA Internal Medicine
