House fire particles tend to be dominated by charred wood, high hydrocarbon content soot agglomerates from burning plastics and
synthetic fibers, charred paint, and soot coated glass fiber. The charred wood tends to be dominated by Douglas fir or Pine from the structural wood
used in the building. Hardwoods from molding, furniture, and decorator wood is also generally present. The agglomerated soot tends to be absent in
wild fires, fireplace emissions, field burning, and the backyard burning of leaf and plant trimming.
