AI overview
Soot is a black powder made of tiny carbon particles that forms when fuel burns incompletely, and it comes out in the exhaust from vehicles and other sources. It matters because soot pollution affects air quality and human health, which is why devices like particle filters are used to reduce its emissions.

Soot ( ) is a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons. Soot is considered a hazardous substance with carcinogenic properties. Most broadly, the term includes all the particulate matter produced by this process, including black carbon and residual pyrolysed fuel particles such as coal, cenospheres, charred wood, and petroleum coke classified as cokes or char. It can include polycyclic aromatic hydrocarbons and heavy metals like mercury.
