What can be cozier than curling up alongside a wood fire during a cold evening? Despite its romantic image, wood fires are a potential source of health issues linked to the pollutants released during combustion. Since 1988, the U.S. Environmental Protection Agency (EPA) has regulated the use of wood stoves in the home as a result of pollution concerns. While a fire may warm your toes, wood fires are an environmental risk.
History
The types of pollutants that are released during wood fires have varied through history with the material being burned and the additives used.
Major Pollutants
Carbon monoxide and nitrogen oxides are two major pollutants released during wood fires.
Identification
Several additional organic pollutants are associated with burning wood, such as benzene and formaldehyde.
Particulate Matter
Particulate matter consists of solid particle matter such as carbon char and is classified by the EPA as fine or coarse based on its diameter in micrometers (µm).
Phenols
Phenols are highly toxic, white crystalline compounds that are naturally present in wood tar and are released during wood fires.
