Wildfire Particles
Pyrolized Calcium
Oxalate Phytoliths
Pyrolized calcium oxalate
phytoliths are a marker for
forest fire smoke, or any
industrial, commercial, or
other activity that involves
the
burning of plant material
containing a concentration
of calcium oxalate
phytoliths. They have been
used to identify homes
impacted by wildfires,
businesses impacted by
emissions of restaurants,
towns impacted by slash
burns, Teepee burners,
hog-fuel boilers, etc. The
predictable chemical
changes that take place as a
result of short exposure to
high temperatures often
result in a particle with
characteristic optical
properties and a
shape reminiscent of the
original phytolith.
