soot particles
Airborne carbon flecks
Soot particles are the fine black specks of carbon produced by incomplete combustion of organic matter—wood, coal, oil, or other fuels.
The term appears in scientific and environmental contexts discussing air quality and pollution: Soot particles from diesel exhaust contribute to respiratory disease.
Distinguished from ash, which is the mineral residite left after complete burning.
