Wood-burning stoves have been a popular heating source for decades. Unfortunately, wood-burning stoves can emit substantial quantities of pollutants to outdoor and indoor air. Among the pollutants are: chlorinated dioxin, carbon monoxide, methane, volatile organic compounds (VOC), nitrogen oxides, polycyclic aromatic hydrocarbons (PAH), and fine particulate matter (PM10, PM2.5, fine and ultra fine particles). Recent studies indicate that the use of wood-burning stoves for heating of dwellings is one of the important outdoor particle sources [Glasius et al. 2004] in residential district in Denmark. This has resulted in an increase in public exposure to indoor and outdoor wood smoke related pollutants, which has prompted widespread concern about the adverse human health consequences that may be associated with wood smoke exposure.
