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.
(2) No difference in the yield of bacterial mutagens per gram of fuel burned was found between cyclic operation under low and moderate sooting conditions.
(3) The report also warned of a growing risk of contaminated water supply because of sea-level rise and flooding, and poor air quality as hotter temperatures cook the smog, and soot from wildfires drifts across the country.
(4) When soot from those fires settles over the ice, it captures the sun's heat.
(5) The impact of the soot is as significant as it is surprising — it was not mentioned as a warming factor in the UN's major 2007 report on climate change.
(6) Under the same incubation conditions without soot, free B[a]P was extensively metabolized by microsomes, principally to B[a]P-9,10-diol.
(7) Nitrogen dioxide is shown to be a more hazardous pollutant than flame-soot within the given combination.
(8) To determine the factors affecting the bioavailability of particle-associated PAH, we have studied the ability of microsomes to facilitate transfer of benzo[a]pyrene (B[a]P) adsorbed on the surface of diesel exhaust soot particles to the microsomes and the ability of the microsomes to metabolize the transferred B[a]P. 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.
(9) The transport rates of each material component of diesel exhaust particles (soot, slowly cleared organics, and fast-cleared organics) were derived using available experimental data and several mathematical approximations.
(10) The intense phototoxic activity of native soot ingested by the ciliates was shown to be dependent on the amount of polycyclic hydrocarbons contained.
(11) The figure includes around 29,000 deaths hastened by inhaling minute particles of oily, unburnt soot emitted by all petrol engines, and an estimated 23,500 by the invisible but toxic gas NO 2 emitted by diesel engines.
(12) His head pounds, “my chest gets heavy, stomach gets tight” and “I feel suffocated, anxious.” “I have difficulty breathing at the end of the day, my face is black with soot,” says Kumar, waiting for his next fare on a noisy corner in south Delhi, beside a road jammed with honking cars, trucks and buses.
(13) But by far the greatest source of renewable energy used globally at present is burning biomass (about 10% of the total global energy supply), which is problematic because it can cause deforestation, leads to deposits of soot that accelerate global warming, and cooking fires cause indoor air pollution that harms health.
(14) Among carcinogens identified in the work environment, tars, soots and oils with content of polycyclic aromatic hydrocarbons (46.5%), chromium compounds (24.3%), "other" chemicals like ferric oxide, dichlorobenzidine, N-Phenyl-2-naphthylamine (9.1%), and asbestos (9.1%) have predominated in proportions given in brackets.
(15) A rapid optical method for determining the quantity of soot in the lungs of rodents exposed to diluted diesel exhaust has been developed.
(16) In using the standard alkali digestion method for pulmonary asbestos fibre count, it was found that carbonaceous particles often obscured the presence of asbestos bodies (coated fibres) rendering their quantification inaccurate, particularly in lungs with a high soot particle content and a low fibre count.
(17) But when recent observations about the atmospheric height of soot particles were used, a model simulation by the Centre for International Climate and Environmental Research-Oslo (Cicero), published in the journal Nature Communications , found that its warming impacts were roughly halved.

(20) Together, these tricks of the auto trade should increase a car’s fuel economy and lower its carbon dioxide (CO 2 ), soot or toxic nitrogen dioxide (NO 2 ) gas pollution levels by about 10-20%.
