Health Risk Assessment Division, Michigan Department of Public Health, Lansing, Mich., USA Residential wood smoke contains inorganic and organic particulates, ash, car bon monoxide, nitric oxide, nitrogen dioxide, formaldehyde, polycyclic aro matic hydrocarbons (benzo[a]pyrene, benzo[k]fluoranthene, benzo[b]fluoran thene, benzo[ghi]perylene, and indeno[1,2,3-cd]pyrene), phenols and sulfur dioxide. Benzo[a]pyrene and formaldehyde are classified as group B2 and group B1 carcinogens, respectively, by the United States Environmental Pro tection Agency. Reported concentrations and potential health risks of the released contaminants are discussed. In general, wood smoke is an irritant to the eyes, nose, and the respiratory tract. It has the potential to cause chronic respiratory problems. Because there are indications that wood smoke may cause adverse effects on human health, exposure to this source of air pollution should be minimized.
