( what is
size (in meron) of particulate matter in
smoke and mist?
Answers
Answer:
Particle sizes for PM from solid waste combustors usually range from 0.01 to 300 microns (micron, one-millionth of a meter) in diameter; 20 to 40 per cent of PM is less than 10 microns in diameter; and up to 10 per cent is less than 2 microns in diameter

What is PM, and how does it get into the air?Size comparisons for PM particlesSize comparisons for PM particlesPM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.
What are the Harmful Effects of PM?
Particulate matter contains microscopic solids or liquid droplets that are so small that they can be inhaled and cause serious health problems. Some particles less than 10 micrometers in diameter can get deep into your lungs and some may even get into your bloodstream. Of these, particles less than 2.5 micrometers in diameter, also known as fine particles or PM2.5, pose the greatest risk to health.
