All of the options mentioned (salt from the sea, volcanic eruptions, emissions from engines, and soot from fires) are important sources of particles in the atmosphere. Salts from the sea are aerosols that contribute to particulate matter in the atmosphere. Volcanic eruptions can release ash and sulfur dioxide that can contribute to air pollution. Emissions from engines, especially from transportation sources, are significant contributors to particulate matter in urban areas. Soot from fires, especially from wildfires, can also contribute to air pollution.
