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. 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 quantitated. 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."
[Science, Vol. 266 Oct. 21, 1994,T.J. Nestrick and L.L. Lamparski, Anal.
Chem. 54, 2292 (1982)].
"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]

Winters in Canada are getting even colder.
With the ban on wood logs being next.
