PM10 is emitted by which sources?

PM10 is emitted by which sources?

• A. Volcanoes
• B. Sea spray
• C. Wind-blown soil
• D. Diesel engines and burning wood

Answer: (D)

PM10 are particles with a diameter of 10 micrometers or smaller, and they are commonly produced by burning fuels. Combustion processes release fine soot, ash, and other particulates that stay suspended in the air, making diesel engines and burning wood typical sources of these particles. While natural sources like volcanoes, sea spray, and wind-blown soil do emit airborne particles, their contributions to PM10 are more variable and often dominated by larger or different particle types; the combustion sources consistently produce substantial PM10 in many environments. This is why diesel engines and burning wood are the best match for PM10 emissions.
