Particulates PM10 PM2.5 TSP monitoring

Sampling dust and particulate matter is important as dust and particulate matter can affect the health of human populations, as well as the natural environment. Dust and particulate matter can cause respiratory problems when breathed in by humans. Dust and particulates above 10 micrometer (PM10) are filtered and generally do not enter the lungs.

Dust and particulates below PM10 are likely to enter the lungs. Dust and particulate matter that is smaller than 2.5 micrometers (PM2.5) can enter into the Alveoli where gas exchange occurs. This PM2.5 is more dangerous as it can affect the exchange of gases within the lungs and even penetrate the lung into the blood stream and cause other health issues.

These two size classes (PM10 and PM2.5) are the normal sampling standards found throughout the world, they represent the particulate pollution that effects human health and thus sampling them provides an accurate insight into how dust and particulate matter at both PM10 and PM2.5 effect human health.
