Cooper: 1980 Environmental Impact of Residential Wood Combustion Emissions and its Implications
Constituents of Wood Smoke from an EPA Study.
Dioxin:"Burning 1 kilogram of wood produced as much as 160
micrograms of total dioxins. This result was obtained when various
specimens of wood were burned in different stoves. Soot was collected
and analyzed by well-designed and documented procedures. Tetrachlorinated,
hexachlorinated, heptachlorinated, octachlorinated dioxins were
present. The isomers of the dioxins were separated and quantified.
The highly chlorinated dioxins were the major components. In the
soot from a series of experiments, their total content ranged
from 10 to 167 mg/kg of fuel. The total yields of tetrachlorinated
dioxins (TCDDs) ranged from 0.1 to 7.8 mg/kg of fuel."

Radwaste from Fireplaces in United States "With the exception of some very low California readings, all measurements of wood ash with fallout-cesium exceeded - some by 100 times or more - the levels of radioactive cesium that may be released from nuclear plants (about 100 picocuries per kilogram of sludge). Wood ash-cesium levels were especially high in the Northeast" [Science News, 1991]

Outdoor Wood Boilers pose a burden of smoke pollution year round as they are used to heat water in addition to residential heat.
