Transmitted Off Crossed Circular Polarized Light


Charred wood particles in homes are often the result of backdrafting from a fireplace or wood stove. Charred wood is almost always present in indoor samples as part of the ambient particle load from outside.

Significance in the Environment:

Charred wood is one of the most common urban and suburban airborne particles. In the winter in northern latitudes in can be one of the major airborne particles. In areas where agricultural fields are burned, charred plant material can become the major airborne contaminant. Proximity to wild fires is another source of charred wood. It is always best to match the charred plant material to the plants being burned to confirm the source. Phytoliths become important in identifying the plant of origin.
