Burning solid fuel yields particulate pollution - solid
particles smaller than a red blood cell which have been
implicated in 30,000 deaths in the US and 2.1 million deaths
world wide per year. . "Particulate pollution is the
most important contaminant in our air. ...we know that when
particle levels go up, people die1. "
Indeed, wood smoke is chemically active in the body

“Each year, smoke from wood stoves and fireplaces
contributes over 420,000 tons of fine particles throughout the
country – mostly during the winter months. Nationally,
residential wood combustion accounts for 44 percent of total
stationary and mobile polycyclic organic matter (POM) emissions
and 62 percent of the 7-polycyclic aromatic hydrocarbons (PAH),
which are probable human carcinogens and are of great concern
to EPA.”3
