About Particle PM2.5
Airborne particles less than 2.5 micrometres in diameter, referred to as PM2.5, can be hazardous to human health or cause a nuisance when present in the air at elevated levels. They are capable of penetrating the lower airways of humans and can cause possible negative health effects.
The guideline for Particle PM2.5 is 25µg/m³ (24hr avg).
Particle PM2.5 is measured in micrograms per cubic metre.
