Soot is an accumulation of impure carbon particles resulting from the incomplete combustion of hydrocarbons. The most important effect on human health is that it causes various types of cancer and lung diseases.
Soot (soot), a pollutant carried in the ambient air, consists of many different sources, all of which are the result of a pyrolysis process. The thermal decomposition of materials at high temperatures in an inert atmosphere is called pyrolysis. In this process, the chemical composition of the burning material changes. The main sources of soot are: internal combustion engines, power station boilers, ship boilers, central steam-heat boilers, waste incineration, field burning (stubble burning), fires, forest fires, fireplaces and furnaces. At the same time, oil lamps, candles, quartz and halogen bulbs, exhaust emissions of vehicles and malfunctioning furnaces are also sources of soot.
Very low concentrations of soot accumulate on surfaces and from ventilation systems. Soot also causes discoloration of walls, ceilings, floors and surfaces.
The formation of soot is largely dependent on the composition of the fuel. The sooting tendency of fuel components is listed as naphthalenes, benzenes and aliphatics. Institution formation is a complex process. A series of molecules undergo many chemical and physical reactions within a few milliseconds. Soot is a powder-like form of amorphous carbon.
Soot contains polycyclic aromatic hydrocarbons (PAHs) and these are known mutagens.
Soot, especially diesel exhaust pollution, accounts for more than a quarter of the total hazardous air pollution.
