Soot is the dark residue formed during the burning of coal and wood. This chemical is categorised as a combination of impurities in carbon produced by inappropriate burning of hydrocarbons.

Although soot is frequently thought of as a fire’s harmless byproduct, it is actually an airborne contaminant that can be dangerous to breath. Numerous additional activities, such as the burning of garbage, steam boilers, and internal combustion engines, also produce soot. Particle filters are typically employed to lessen the amount of soot emitted into the air in the case of gasoline and diesel engines.
