There is ample evidence that residential wood combustion (RWC) emits significant quantities of pollutants that are
known to impact health, including particulate matter, carbon monoxide, nitrogen oxides, and a number of known human carcinogens, including benzene and polycyclic aromatic hydrocarbons (Naeher et al., 2007). According to the U.S. Environmental Protection Agency (U.S. EPA), exposure to fine particulate matter (particles with an aerodynamic diameter equal to or less than 2.5 micrometer, i.e., PM2.5) from woodsmoke is a major health threat (U.S. EPA, 2009).
There is a large body of evidence showing cardiovascular and respiratory health effects associated with ambient PM2.5 concentrations (Brook et al., 2010). The U.S. EPA has set national PM2.5 ambient air quality standards for annual and daily (24 hour) averaging times, but sub-daily elevated periods of PM2.5 can also be of concern.
Recent work has identified adverse respiratory impacts specifically from sub-daily (4 hour) exposures to woodsmoke (Barregard et al., 2006; Barregard et al., 2008; Danielsen et al., 2008).
Further, wood burning appliances are typically operated inresidential areas so that a large fraction of emissions can result in concentrations to which people are actually exposed (Ries et al., 2009).
A key challenge in the assessment of woodsmoke conditions in rural areas is the location of wood burning
sources, compounded by landscape features such as valleys. These features can create significant PM2.5 spatial
variability, including “hotspots” of elevated concentrations on top of regional PM2.5 contributions. Regulatory ambient air pollution monitoring networks are typically not dense enough, particularly outside of major urban areas, to effectively characterize this spatial variability.
