Say, let's get governments to ban forest fires. They must release an awfully lot of this stuff. And, of course, the are man-made since forest fires didn't exist more than 400 years ago - right?

Yep it is going to get chilly. No burning wood..
Wood Burning Creates Dioxin, Radioactive Particles and Releases Stored Lead
Lead: produced from burning 2.2 pounds of wood = 0.1mg to 3 mg.
"Burning 1 kilogram of wood produced as much as 160 micrograms of total dioxins.
his result was obtained when various specimens of wood were burned in different
toves. Soot was collected and analyzed by well-designed and documented
rocedures. Tetrachlorinated, hexachlorinated, heptachlorinated, octachlorinated
ioxins were present. The isomers of the dioxins were separated and quantitated.
he highly chlorinated dioxins were the major components. In the soot from a
eries of experiments, their total content ranged from 10 to 167 mg/kg of fuel.
he total yields of tetrachlorinated dioxins (TCDDs) ranged from 0.1 to 7.8
g/kg of fuel."

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