Black carbon aerosol is another name for:

The correct answer is Soot.

Key Points

• Black carbon aerosol, commonly known as soot, is a significant component of particulate matter (PM).
• Soot is primarily produced from the incomplete combustion of fossil fuels, biofuel, and biomass.
• It consists of fine particles that are less than 2.5 micrometers in diameter (PM2.5).
• These particles are known to have adverse health effects, including respiratory and cardiovascular diseases.
• Black carbon aerosol contributes to global warming as it absorbs sunlight and heats the atmosphere.

Additional Information

• Smog: A type of air pollution that is a mixture of smoke and fog, typically resulting from industrial and vehicular emissions.
• Smoke: A visible suspension of carbon or other particles in the air, typically produced by burning organic matter.
• Ozone: A reactive molecule composed of three oxygen atoms, found both in the Earth's upper atmosphere (where it is protective) and at ground level (where it is a pollutant).
• Particulate Matter (PM2.5): Fine inhalable particles, with diameters generally 2.5 micrometers and smaller, which can pose health risks when inhaled.
• Black carbon's impact on climate is distinct from long-lived greenhouse gases as it has a shorter atmospheric lifetime but is highly effective at absorbing sunlight and heating the atmosphere.
