Health effects of residential wood smoke particles: the importance of combustion conditions and physicochemical particle properties

Table 2 Emission characteristics for the different classes of wood combustion appliances

Type of combustion appliance	Particle class(es) dominating the emissions	References
Open fireplaces	organic carbon/soot	[14, 58, 62, 64, 67]
Conventional wood stoves	organic carbon/soot	[12, 62, 64, 67, 81]
Masonry heaters	organic carbon/soot	[11, 76, 119]
Conventional boilers for wood logs	organic carbon/soot *
Modern wood stoves	inorganic ash/organic carbon/soot *
Modern boilers for wood logs	inorganic ash/organic carbon/soot *
Pellet stoves and boilers	inorganic ash	[69, 120]

Based on the available data on the physicochemical properties of particles emitted from different types of combustion appliances we have suggested the class(es) of particles that are likely to dominate the emissions. The references used to support the text are included in the table.
