What is in Wood Smoke?

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]
