What is PM 2.5 and why we need to worry
Particulate matter (PM) of the order of size of 2.5 microns is called PM2.5. According to the World Health Organisation (WHO), PM 2.5 can penetrate the lung barrier and enter the blood system.
“Chronic exposure to particles contributes to the risk of developing cardiovascular and respiratory diseases, as well as lung cancer,” states the WHO website.
The particles with a diameter of 10 microns or less (PM10) can penetrate and lodge deep inside the lungs.
