What is PM 2.5 and how different it is from PM 10?

Particulate matter (PM) refers to tiny particles or droplets in the air with a diameter of 2.5 micrometers or less. PM 2.5 are so tiny that they can enter the Bronchia and the Alveoli, while the PM 10 can only reach the nasal cavity, its just the matter of the size between PM 10 and PM 2.5. Both can be associated with health concern issues, since the particles are so small that can transmit deeper into our respiratory system.
