Excerpt: “Our analysis demonstrates that in most U.S. residences PM2.5, acrolein, and formaldehyde dominate health impacts due to chronic exposures to nonbiological air pollutants. The DALY losses from these three pollutants appear to be much larger than the DALY losses due to CO deaths from acute poisoning in homes.
SHS and radon are also significant contributors to populationwide DALY losses, but these exposures occur in a smaller fraction of homes. Formaldehyde is primarily emitted from materials throughout the home. Similarly, acrolein is also emitted from such materials; however, cooking is also a potentially significant indoor source (Seaman et al. 2007). PM2.5 concentrations indoors, unlike acrolein and formaldehyde, are due to both indoor and outdoor sources, and outdoor concentrations may exceed indoor levels in many locations (Weisel et al. 2005).”
PM: Particulate matter
DALY: disability-adjusted life-years
SHS: secondhand smoke
