Pollutants.
What we measure and why.
Particulate Matter (PM1, PM2.5, PM10)
Risk Level: High Risk
Category: Pollutant – Fine and Ultra-Fine Airborne Particles
Description:
Particulate Matter (PM) refers to a mix of tiny solid and liquid particles suspended in the air, classified by their size. Due to their small size, PM1 and PM2.5 can penetrate deep into the respiratory system, bypassing natural defences and entering the bloodstream. Chronic exposure increases the risk of cardiovascular diseases, respiratory illnesses, and neurological disorders. Vulnerable groups such as children, the elderly, and individuals with pre-existing health conditions are most at risk.
Health Effects:
-
PM1: Associated with systemic inflammation, oxidative stress, and potential impacts on brain health.
-
PM2.5: Causes respiratory irritation, worsens asthma, and contributes to cardiovascular problems.
-
PM10: Triggers respiratory discomfort and can aggravate conditions like bronchitis.
