Forest Fire

Forest fires create strong winds and carry large amounts of burnt soil, charred wood and plant material, pyrolized phytoliths, and other charred biologicals in their plume.

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.
