Soot


Definition:

  • (n.) A black substance formed by combustion, or disengaged from fuel in the process of combustion, which rises in fine particles, and adheres to the sides of the chimney or pipe conveying the smoke; strictly, the fine powder, consisting chiefly of carbon, which colors smoke, and which is the result of imperfect combustion. See Smoke.
  • (v. t.) To cover or dress with soot; to smut with, or as with, soot; as, to soot land.
  • (a.) Alt. of Soote

Example Sentences:

  • (1) With the exception of PMMA and PTFE, all plastics leave a very heavy tar- and soot deposit after burning.

  • (4) When soot from those fires settles over the ice, it captures the sun's heat.

Our results indicate that rat lung and liver microsomes were able to facilitate the transfer of small amounts of B[a]P from diesel particles (less than 3%), but only a fraction of the amount transferred (1-2%) was metabolized.
