Soot from an Apartment Fire

This is from an environmental tapelift collected in an apartment that experienced a fire.

Reflected Darkfield Illumination

Definition/Function:

High hydrocarbon content soot agglomerates are black, very low reflectivity, globular, loosely consolidated masses of submicrometer soot particles.

Significance in the Environment:

High hydrocarbon content soot agglomerates are typical of uncontrolled fires where liquid fuels are involved. Liquid fuels include any plastic that forms a liquid as it is heated. These particles have a very high sticking coefficient and tend not to travel far from the source.

Characteristic Features:

The soot particles are organized into fractle submicrometer, micrometer, multiple micrometer, and tens of micrometer units making up the single mass. This opaque fractle structure from the nanometer scale through the tens of micrometers is the characteristic feature.
