Many restaurants and restaurants in the catering industry produce lampblack, which is discharged outside without any organization or purification. Oil fume contains a large amount of hydrocarbons, which can easily mix with other dust in the atmosphere to form inhalable particulate matter and destroy air quality. Edible oil smoke is one of the main sources of volatile organic compounds (VOCS) and PM10 (inhalable particulate matter, particulate matter less than 10 microns) in the atmosphere.
