  • Soot
    • It contributes to the warming of the atmosphere.
    • Black carbon is a form of particulate air pollutant.
    • It is produced from incomplete combustion.
    • It consists of pure carbon in several linked forms.
    • The source of the black carbon includes biomass burning, cooking with solid fuels and diesel exhaust, etc. 
  • Haze
    • It is traditionally an atmospheric phenomenon in which dust, smoke, and other dry particulates obscure the clarity of the sky.
    • It is the main cause of air pollution.
    • Dense haze is known as Smog.
  • Mist
    • It is a phenomenon caused by small droplets of water suspended in the air. 
    • Mist often forms when warmer air over water suddenly encounters the cooler surface of the land.
    • Mist is thinner and more transparent.
  • Fumes
    • It refers to vapors (gases), dust, and/or smoke given off by a substance as a result of a chemical transformation such as reaction, heating, explosion, or detonation.
    • Inhalation of fumes causes symptoms of cough, shortness of breath, eye, nose, and throat irritation, and upper chest pain.
