What comes out of a smokestack?

Smoke, along with various gases and particulate matter, typically comes out of a smokestack. This emissions include pollutants such as carbon dioxide, nitrogen oxides, sulfur dioxide, and sometimes unburned hydrocarbons, depending on the type of fuel being burned. Additionally, depending on the filtration and scrubbing systems in place, there may be varying levels of harmful substances released into the atmosphere. Proper regulation and technology can help minimize these emissions to protect air quality.
